9 tips to start the year saving on electricity

9 tips to start the year saving on electricity

Unfortunately, Spaniards face higher electricity and light costs every year. This means that keeping our house lit and at a suitable temperature becomes a complicated and quite expensive. Next we will review nine tips to start the year saving electricity :

  1. Isolate your house It is the best way to achieve an efficient energy consumption. By controlling the air leaks through doors and windows, we will be able to maintain the adequate temperature in our home much better and, therefore, not waste energy.
  2. Replaces halogen bulbs by LED . The LEDs represent an initial outlay of important money, since they are more expensive. However, we will save between 80 and 90% of the electricity consumption in lighting. In addition, the lifespan of the LEDs is much higher than that of conventional bulbs.
  3. Use efficient heating and cooling equipment . Class A or higher heat pumps are much more efficient than electric radiators or electrical resistance convectors. In the case of boilers, condensing boilers are the best.
  4. Set the heating and air conditioning to the correct temperature . It is recommended that this be between 19 and 21 degrees in winter and between 24 and 26 degrees in summer. Keep in mind that each degree of more or less can increase consumption around 7%.
  5. Take advantage of solar heat . In summer it is recommended to open windows in the morning and at the end of the night, to cool the house. In winter, quite the opposite.
  6. Use class A or higher appliances . The energy consumption of low-energy appliances is much lower than that of a conventional appliance. For example, a class A +++ refrigerator consumes about 70% less energy than a normal class model.
  7. Adjust the contracted power . It is advisable to reduce it to the minimum necessary, in order to reduce the electricity bill. When calculating your ideal hired power, keep in mind that you will rarely use all the appliances at once, so it is better to stay short than to spend.
  8. Compare offers from other electric companies . Once a year we should review our invoice and compare it with the offers offered by the rest of the companies. There are online comparators that can be very helpful.
  9. Unplug all equipment that you are not using . Phantom consumption (stand-by) can amount to 7% of household electricity consumption, according to Eurostat. We have to finish him.

We are sure that by applying these simple tips the saving of the energy bill of your home can be important.

How is Solar Energy produced?

Solar energy is generated when sunlight hits the solar panels, which then convert solar energy into electricity suitable for our homes. This photovoltaic transformation is the way in which solar energy is produced. In this post, we will analyze in depth how a domestic solar system takes advantage of the sun’s energy.

Solar panels convert sunlight into energy

The process of creating energy from sunlight begins with the most important part of a solar installation: solar panels . A typical solar panel is made of monocrystalline or polycrystalline silicon housed in a metal frame with a glass housing.

When sunlight strikes the thin layer of silicon at the top of a panel, it releases electrons from the silicon atoms. The electrons have a negative charge, which means that they are attracted to one side of the silicon cell. This creates an electrical current that is captured by the wiring of the solar panel.

Known as the “photovoltaic effect”, electrons that flow and have been released by sunlight are the basis of electricity generated from solar panels. The more sunbeams fall on the solar panels, the more electrons will be free, so it is important to consider factors such as shade and local cloud cover when designing a solar energy system.

Different solar panels produce electricity at different speeds depending on their efficiency and quality. High quality solar panels will often cost a bit more, but in the long term they will save you money because they produce electricity more efficiently.

Investors convert the energy of solar panels into usable electricity

Once the loose electrons have been collected in individual panels, the resulting current is known as direct current. The electricity we use to power devices, charge electric vehicles and turn on our lights is alternating current. The electricity generated by loose silicon electrons is DC electricity and must be converted to AC power before we can use it.

This conversion is done through devices called inverters . The inverters can be configured as chain inverters, microinverters or power optimizers, but each configuration performs the same general function of converting DC electricity into AC electricity. Once the DC electricity goes through the inverters and it becomes AC electricity. In this way, solar energy can be used at home or in the general electrical network.

Other solar panel technologies

Most of the available solar panels are made of crystalline silicon, but there are some other types of solar panels that produce electricity from the sun.

Cadmium telluride solar panels (CdTe)

CdTe panels use a material other than silicon to produce electricity. While they do not have very high efficiency ratings (yet), CdTe panels can capture solar energy at shorter wavelengths than silicon panels. In addition, manufacturing costs are low.

Solar panels of copper and Indian diselenide (CIGS)

With greater efficiencies than CdTe panels, CIGS panels are a promising panel option. Unfortunately, high production costs have prevented CIGS panels from reaching the general public. CIGS panels use a different material based on copper to generate electricity.

Organic photovoltaic cells (OPV)

Instead of using an inorganic material such as silicon or copper, OPV cells use thin layers of organic vapor to generate an electric current from sunlight. OPV cells have not yet been widely used due to low efficiency and short life compared to other panel technologies.

All these solar technologies fall under the umbrella of thin film panels, and are a very small part of the solar energy market in general. This is mainly because they are not profitable at present. In the future, these options may be technologies that dominate solar energy, but for now silicon solar panels dominate the industry.

How to save on the electricity bill with self-consumption?

Image result for solarElectric self-consumption with solar energy has completely revolutionized the energy sector. We have discovered freedom, independence and sustainability in the same system. At SotySolar we have taken a step further to become your solar advisor , your independent advisor capable of designing the best solution for your company or your home. How do we do it? Now we tell you.

What is self-consumption?

Energy self-consumption through photovoltaic panels is freedom. Thanks to your own installation of solar panels you can capture the energy of the sun and transform it into electricity. What it means to say goodbye to the bill of light.

You can choose an independent installation for your own consumption that will be supported by batteries that store energy . In this way, you will guarantee a constant and continuous supply over time. It is a way to have light anywhere, without paying the high transport costs of the electricity distribution network. These facilities are formed by solar panels , a charge regulator, solar accumulators and photovoltaic inverters.

On the other hand, there is the model connected to the network. It is a system connected to an internal circuit of consumption and the general network. In this case you do not need batteries or accumulators, because if at a specific moment you need more electricity, you always have the electric network at your disposal. In addition, you can choose only to self-consume the energy or even sell the surplus green energy to the electricity companies and charge for it.

Why does SotySolar propose a different system?

The generation of energy through solar panels is not new. Our main innovation is our own business model. We are solar consultants, we connect companies or individuals who want an installation with professionals in the sector.

What we do is conduct a study of each case, completely free, so you know how much you can save on the electricity bill . With the data we obtain, we focus on designing the best solution and finding the most adjusted budget. For this, we have a network of installers, manufacturers, distributors and professionals in the sector. Thus, we guarantee the best price and the maximum guarantee. We advise you and we accompany you throughout the process. And also, to make it more comfortable for you, you can do it online .

The whole process in five easy steps

Once you have contacted us, we start working.

1. The roof

Publishing the roof is the first step and it is very important. We need to know where to install solar panels to analyze their situation and their possibilities. We will also ask you for a electricity bill to know what your consumption is and tell you the savings you are going to get.

2. The offers

Once we have located the roof and we have studied the situation, our platform is put to work to make a selection of self-consumption budgets with the installation of solar panels, the financing options customized for you and, then, we process all the information to send it to you in a simple and understandable format. We like to say that our mission is to facilitate the purchase of photovoltaic solar energy installations. No more secrets, transparently and without having to find budgets until you feel lost .

As we are independent and we want the best for you, our advisors accompany you and advise you in your choice. If in the end you decide not to accept any offer, do not worry, you just have to communicate it so that the installers update their database and do not contact you anymore.

3. The agreement of the conditions

If you decide to take the step towards sustainability, green energy and savings, with a clear budget, it is time for you to choose the installer. You only need to click on the “Choose Installer” button and from there confirm the budget. From the platform we notify the professional or installation company that you are interested in hiring their services, but you have to know that you are not obligated and that you can change your mind. In any case, from this moment, it will be the technician who will contact you to send you the contract and the conditions.

4. The installation

Once you have signed the contract, it is time for installation. The same installer will request the permissions and will manage the documentation that is needed and, in addition, will help you to present the applications to receive grants or subsidies. If you live in a house, in two or three days you will have your installation ready. In the case of industrial buildings, the time depends on how big it is.

5. Save

Once the installation is underway, say goodbye to the electricity bills . It is the moment when you feel free and start saving. From the zero minute you will begin to generate green , clean and sustainable energy . From there you can evaluate the installer , share your experience, monitor your consumption and, if you wish, participate in our forum to talk with others like you.

  • Social Security

The Valencian Government has signed an agreement with several companies marketing the energy sector to avoid water, electricity and gas cuts to people and families at risk and social exclusion , who may request a report from the municipal social services to stop the suspension process of the supply while the Generalitat manages the payment of the invoices owed.

The agreement was signed today by the representatives of Endesa , Gas Natural Fenosa and Iberdrola , and by the president of the Generalitat, Ximo Puig, in an act that also attended by the Minister of Housing, María José Salvador, and the vice president of the Consell and consellera of Equality and Inclusive Policies, Mónica Oltra, whose department coordinates the policies of fight against the energetic poverty.

The president of the Government has described this agreement as "essential" because it "improves the lives of people with more needs", and stressed that the objective of the Consell with this agreement is to ensure that Valencian families "have a decent winter", and do not have the "energy poverty among their concerns". Puig has ensured that the Valencian Government is going to continue working so that energy poverty "does not exist in the Valencian Community", for which a Valencian Plan for the Struggle against Energy Empowerment has been launched, in which Agreements with the marketers also include direct aid to citizens.

The vice president of the Consell has highlighted the importance of agreements such as today that allow large companies to commit to what is a "constitutional right" of citizens and has expressed the commitment of the Council to continue working to add the rest "With corporate social responsibility initiatives such as this, which will avoid cutting off basic supplies or at least notify social services so that they adopt social protection measures."

This agreement will initially benefit 12,000 households, although the goal is to reach 50,000. For this the Ministry of Housing, Public Works and Vertebration of the Territory is going to implement a budget line of 3.7 million euros, which can accommodate those families or people at risk of social exclusion for having an income of less than 1 , 5 IPREM or 2 times IPREM if you live with people with disabilities or high dependency.

The aid to avoid energy poverty will be in cases of electricity or gas cut of 75 euros per monthly bill and up to a maximum of 300 euros per consumer per year, and in case of drinking water cut, up to 15 euros per monthly receipt and a maximum of 60 euros per consumer per year. In addition, the costs incurred to restore supplies in the event of a cut may be subject to aid.

The social services of the local councils will be in charge of detecting households in a situation of vulnerability, with serious difficulties for the payment of electricity or gas supply, or that have already suffered a power cut to their habitual residence, and of being thus they will make an assessment to determine if they can be beneficiaries of the aid. If this is the case, it will notify the supply companies and the regional administration and the suspension of supply procedure will be paralyzed while the payment of the invoices owed is managed. Likewise, if it meets the requirements, the social services will inform the marketing company and the Regional Ministry and the procedure of suspension of the supply will be paralyzed while the payment of the invoices owed is managed.

Immediate restoration of service

For its part, the supplying company will immediately request the restoration of supply. Likewise, they will not request again the suspension of the supply while the granting of the aid is managed. Neither will they require payment of any interest. The City Council will pay directly to the company the total amount of the debt and if the supply has been restored, the rights of reconnection. In addition, the payment of the debt will be communicated to the Generalitat, which will process the payment to the consistory of the amounts it has paid.

The publication of the order that will allow municipalities to apply for these grants will occur at the end of December, although municipalities may adhere to this call from tomorrow, and the payment of grants will be retroactive until October.

1.4 million in aid for households in social exclusion

On the other hand, the Department of Equality and Inclusive Policies will allocate a total of 1.4 million euros in aid for those persons or families who are in a situation of social exclusion, having annual incomes of less than 5,009 euros and have been notified by the supplying company the order to cut water, electricity or gas. This aid will be processed through the municipalities of more than 20,000 inhabitants with the aim that the affected people do not have to do more bureaucracy than the precise, and will be effective from next January 1.

The vice president explained that this aid aims to guarantee a "constitutional right" as it should be the basic supply of water, electricity and gas, and stressed that they will also go to families without children and the elderly, who until now "were excluded when, according to all the studies, they are the group most affected by this situation ". Oltra has stressed that it is also working hand in hand with the large cities and the councils "to expand social investment to combat energy impoverishment", and in this regard has indicated that the Diputación de Valencia "has already announced a departure of 400,000 euros for the towns of less than 20,000 inhabitants ".

For its part, the Ministry of Sustainable Economy, from the IVACE, will work on raising awareness and awareness of the efficient use of energy, in addition to implementing energy saving measures and / or rehabilitation of the homes of families in social exclusion or at risk of being, as pointed out by the vice president.

How to stop fearing and saving with the electricity bill?

Image result for electricityThe dreaded day has arrived, we enter our portal, we open the mailbox and … BINGO! There is the letter from our beloved electric company, what will it be this time? Will I have won some sort of draw?

Well no, against all odds it’s about the bill of light , and what is my face of amazement when I realize that, oh surprise! it has gone back up …

Why does not the receipt of light continue to rise and more now that winter comes?

What will have happened? What is the reason for this “exceptional” increase? surely it will be because of a war in a strange country, or perhaps it is due to another “debt” of the state with some figure of the electrical system. Nothing farther from reality, this time the blame has fallen on the weather.

As you read, this time the responsibility of Spaniards to pay 12% more on our electricity bill is of the weather, and is that going through one of the driest years that are remembered serves as a perfect excuse to justify the increase of the invoice in this year 2017.

– Surely the Government will have taken measures to deal with such a setback. Well, a priori it seems that no, maybe our best option is to invoke the God of rain, wait for us to listen and no one can think of another excuse to return to raise the bill of light next year.

But does Spain and the electricity bill really depend so much on hydroelectric power?

Well, the truth is that no. It is evident that our country can not risk its energy production to a scarce resource such as water. And a good proof of this is that only 29% of the renewable energy that we produce comes from hydraulic energy compared to 98% that produces a world power in this matter, such as Norway.

In other words, in Norway, as they have an abundance of water, they make the most of it, and here we blame the scarcity of a scarce resource for the increase in the electricity tariff. Would not it be better, I say, to look for an abundant resource within our borders and get the most out of the purest Norwegian style?

At this point, the bulb is turned on to a server, never better said. Spain is a world-famous country because of multiple factors, but the Sun may be the most relevant, do not you think?

Well, it seems that a brilliant mind of this country had this idea before me and I am sure that it intentionally took charge of putting all the obstacles possible to the exploitation of the most important energy resource that we have at our disposal.

Think about it for a moment, what would be the excuse to justify a new increase in electricity rates with a much stronger generation of solar energy ? They would surely end and it would be time to put the cards on the table.

How can we save on the electricity bill at the end of the month?

Luckily for us, it is not necessary to wait for that moment to come, it is in our power to take charge of our energetic transformation. With self-consumption solutions we protect ourselves against the constant rises in the price of electricity. Self-consumption will allow you to save directly on the variable term of your electric bill. In addition, in some cases you can lower the electric power contracted by reducing the fixed cost and also if you hire a rate with time discrimination you can maximize the savings on your bill even more .

It should be remembered that self-consumption is a right and to become the owners of our own energy depends solely on ourselves. We have the opportunity to be part of the energy transition as active members. Are you going to waste it?

Reduce heating costs and electricity costs with Smart Home

The guides provide general information. Product details of CosmosDirekt can be found on the respective product pages.

When the window opens, the heating is switched off. When you leave the home, all the lights go out, and so does the radio. Smart home systems help save energy. Especially in the household, where electricity is often wasted by negligence, such automatic solutions are useful. In the article we introduce the appropriate devices that you can use to save energy.

  • Save energy with a smart home heating control

  • Reduce power consumption

Nobody likes to waste money, but many people do – mostly without intention or negligence – because the window is open for ventilation for a quarter of an hour, while the heating continues to boil. The TV is on standby all day, even though there is no one at home who could turn it on. Classic examples of how fast energy is wasted – and how to spend more money unnoticed than necessary. This is where smart home solutions come into play: you can save energy in the home even if you do not think about it. Thanks to intelligent networking, heating and power consumption can be limited to the necessary level.

You should know these terms

sensor Also referred to as a detector, transducer or probe. The sensor can detect certain physical (or chemical) properties: temperature, humidity, light, speed and the like. In the smart home they play an important role as signal generators: If a certain value is exceeded or undershot, this triggers a signal to a connected device.
standby English for “be prepared”. Therefore, also called standby mode for electrical appliances. The actual functions are switched off, but the device can be returned to the function mode without long waiting times. Energy is needed to maintain the standby mode. The consumption is lower than in the operating mode, but adds up over time.

Saving energy with a smart home heating control

The fact that it is possible to increase comfort with Smart Home is obvious: While you step into the shower in the morning, the heating control via Smart Home has already brought the bathroom to a comfortable temperature. Upon entering, the motion detector activates dim light and the radio plays quietly in the background. But Smart Home can do even more: if the last member of the family leaves the apartment, the controller will keep the heat output to a minimum, just high enough to prevent it from cooling down throughout the day. Then the heating control can bring the home back to comfortable temperatures by app or by time switch function, before the first family member comes home again.

These smart devices help save energy

70 to 80 percent of all energy costs are incurred for heating and hot water. For a 70 m 2 apartment in 2015, that was an average of about 1,000 euros, determined the nationwide heating mirror, a cooperation of the non-profit consulting company co2online and the German Tenants’ Association. With Smart Home it is possible to save up to 30 percent of these costs . Every year, that’s 300 euros more in your wallet , thanks to smart thermostats and intelligent heating control via smartphone. We introduce you to various smart home appliances that help save energy and increase comfort in the home.


A reduction of the living temperature by just 1 ° C pays off: you save about 5% to 6% of the heating costs.


The thermostat is simply plugged onto the valve of the radiator and integrated into the Smart Home system – it is ready for use. It automatically regulates the room temperature according to your specifications, which are stored in the heating profile of the room. The heating control can also be regulated by app or remote control. In general, a temperature change is possible directly on the thermostat. Remote access can even raise or lower the temperature while you are on the move. If there is a connection with a door and window contact, the thermostat automatically switches off the radiator when the door or window is opened. Only after closing the heater is reactivated.

room thermostat

The room thermostat can control several radiator thermostats in a room at once. The connection with the underfloor heating is possible. The commands are transmitted by radio, mounting with screws or tape. The heating control is done via the app or PC, by timer or manually on the device. As a rule, room thermostats with several temperature settings are programmable so that individual well-being temperatures can be set for the morning, the day and in the evening. In most cases, a humidity sensor is also integrated, which controls the temperature so that no mold can form. Networking with door and window contacts is also possible. Because the room thermostat can be mounted anywhere in the room, measure the temperature exactly where you want it.


The optimum temperature in living rooms is between 18 and 22 ° C.

Door and window sensor

This contact first checks whether the door or window secured with it is closed or opened. The status can be checked at any time via the Smart Home app, so that you always know if someone has gained access to the home unauthorized. When combined with a radiator or room thermostat, door and window sensors also help save energy. If there is magnetic contact, the heater can run. When the contact is released, the thermostat throttles the radiator. Many suppliers can use the heating control to determine when the sensor transmits its signals. Thanks to a programmed delay, it is possible to prevent the heating system from being shut down when the windows are opened for a short time and then restarted.

Humidity and temperature sensor

For indoors and outdoors, there are sensors that measure temperature and humidity and send this data to the central home control. The sensors are usually mounted on the wall and can measure temperatures from -20 to +80 ° C (outside) or from 0 to 40 ° C (inside). The relative humidity can be between 10 and 90 percent. The data is regularly sent to the control center or a networked weather station. In addition, programming with specific target values ​​is possible via app or directly on the device. If, for example, they exceed or fall below 2 ° C or 10% humidity, the heating control can regulate the thermostat by radio to prevent mold growth on the inside. For external sensors, for example, the connection to electric shutters is conceivable: If the outside is too hot or too cold, the shutters will automatically shut down. In summer, it stays cool inside and warm in winter.

The heating control automatically takes over the direction with profiles

Profiles can be set using the app or the software interface, which causes certain operations to take place automatically . For example, it is possible to automate the raising and lowering of the bath heating in the morning / evening. Many providers allow for a day-specific setting, which, for example, on working days, the profile is activated one or two hours earlier than at weekends. In this way, the right temperature can be assigned for the entire course of the day: cuddly warm in the presence, cool in the absence. In addition, “event profiles” can be defined: Only when all residents – whose location is detected via the smartphone GPS – have left the house will the temperature be shut down. If you have half an hour more time than usual in the morning, the apartment will still be warm.


Which Smart Home profiles are supported and how you create them can be found in the article Smart Home: Installation .

Frequently asked questions about smart home heating control

  • What information is displayed on the radiator thermostat display?
    If the radiator thermostat has been integrated into the smart home system, the display will show an existing network (usually with an antenna symbol). The current room temperature can also be read off. The level of the battery can also be identified by the symbol. Many also show on the display whether a time profile has been activated. Sometimes the time and day of the week are also displayed.
  • To which radiator can the thermostat be connected?
    Smart thermostats can be connected to all standard radiators . It simply removes the old thermostat knob and the new mounted. An exchange of the (through) valve is usually not necessary. Depending on the manufacturer, an adapter ring is required for installation. Many thermostats are compatible with the manufacturers from the outset. For underfloor heating , the simple radiator thermostats are not suitable – this requires special thermostats.
  • Is it possible to set the room temperature even if the heating control has been deactivated?
    Yes. The remote control of the Smart Home system can usually be used to change the temperature. The radiator thermostats themselves have thumbwheels or knobs that increase or decrease the room temperature. Please note: deactivating the Smart Home heating control also switches off the networking with other Smart Home components. This means that the data from door and window sensors can no longer be evaluated. When the heating control is deactivated, an open window will no longer automatically cause the radiator to be throttled.
  • Is it possible to prevent the heating from freezing when the batteries of the radiator thermostat are empty?
    Yes. For most providers, however, the frost protection of the radiator thermostat must be activated. Then the thermostat opens the valves by 15 percent when the batteries go to zero. Otherwise, the valve remains closed, so that the room is not heated unnecessarily when the batteries are empty. Some providers equip their radiator thermostats with a valve emergency position. Then the valve is automatically opened by 15 percent to prevent freezing. For frost-prone rooms, manual activation of the frost protection is recommended, as only then can further parameters such as a minimum temperature be set via the heating control.

What are the benefits of heating control via smart home?

  • You can always set the correct temperature in all heating periods and prevent overheating of the rooms.
  • You can set exactly the periods in which to heat or in which not or only slightly heated.
  • They can optimally regulate the humidity of each room and specifically prevent mold growth.
  • You can also use the app to regulate all functions on the go and to adjust the heating control to unexpected changes.
  • You save between 10 and 30 percent of your energy costs. That’s between 100 and 300 euros per year.

Saving energy made easy: Reduce power consumption with Smart Home

In addition to the intelligent heating control via radio control of power-hungry devices is the second domain of smart home solutions. Of course, the networked control can also contribute to the comfort : The smart socket activates the coffee machine when getting up – as soon as you enter the kitchen, you can expect the freshly brewed coffee. But at the same time, Smart Home helps you to reduce power consumption and thus reduce energy costs . We will introduce you to the key energy saving devices and give you tips on how to further reduce your costs.

Save energy with Smart Home: These smart appliances reduce the power consumption of your household

Fully automatic coffee machines, smart TVs, receivers, wireless routers, printers and laptops – in many households there is plenty of electronics that are only used for a few hours a day, but which are connected to the power grid around the clock. As the German Energy Agency calculated in 2010, the cost of the standby operation of home electronics amounts to an average of 115 euros per year . Particularly fatal: Many modern devices are not even signaled by a light that they run in standby. This also applies to chargers that remain in the socket after you have removed your smartphone or tablet. How high their power consumption is, is difficult to determine. The hidden costs can be quickly and easily tracked down with Smart Home. Saving energy cleverly is then quite easy.

Switching and measuring socket

This device is used to turn on and off electrical appliances. It fits into any normal household socket and can be used in a few minutes. By connecting to the control panel, the connected consumers – from the coffee machine to the radiators – can be switched on and off as required. In combination with a time control, the pot of coffee is brewed punctually every morning by the coffee machine. Or the motion sensor automatically turns on the lamp on the dresser when someone enters the room. Disconnecting the power line will help eliminate unnecessary power in standby with the Smart Switch and Meter Socket. The measurement function also provides information about the power requirement and transmits the values ​​to the app. This allows you to easily monitor and evaluate the energy balance of your devices on smartphones and tablets.


The adapter works in principle as well as the switch and test socket and can also be attached to any household socket. The status can be called up and checked on the go via app. Also, you can easily configure the timing and linking to other elements. In conjunction with the caretaker function, the plug additionally increases safety: then it can switch connected lamps on and off at random to simulate presence. Some providers also enable / disable the connected device directly on the adapter. A measuring function is usually not included.

Wireless wall switch

The wall button – sometimes called a wall transmitter – is an all-in-one switch. Just press the button when leaving the room and the radio in the room and the lights on the shelves and sideboards will go off. And all at once, a tour is no longer necessary. The combination with intelligent radiator thermostats can also be created to save additional energy because the room temperature is lowered. Cabling is usually not necessary, wall switches and wall-mounted transmitters work radio-based. This makes it easy to attach the switch to plaster or to the wallpaper – easily with double-sided tape or with screws at the desired location: next to the ceiling light switch or anywhere else. Per app, the wall button can be configured as desired.


How much power a household consumes depends not only on the number of devices, but also on the number of family members. A one-person household needs about 1,800 kWh, with two people the consumption already increases to 2,700 kWh, with three people to 3,400 kWh. For four people you have to expect about 4,000 kWh. Compare your last electricity bill with these values ​​- and formulate a concrete savings target.

Profiles simplify smart energy saving in the home

Even when saving energy, many functions can be controlled via profiles: Either you create a time profile so that the connected device is activated or deactivated at a certain time. Or you create event profiles . Then the motion sensor can turn on the lights – or you can use the wireless switch to turn off all connected elements at once.


You can find out which Smart Home profiles are supported and how to create them in the Smart Home: Installation article.

Particularly interesting are such time profiles for all who operate a photovoltaic system on the roof . If, for example, a washing machine or a tumble dryer are integrated into the smart home, they can be selectively activated by the control center if the solar system currently supplies a lot of energy. The time period can be set via app control, so that, for example, the laundry is finished when it returns. The exact time when the washing machine is turned on, however, determines the center – which gets information from outdoor sensors about sunshine and strength. The same applies if, for example, e-bikes or electric cars are connected. Then the central office regulates the charge according to the available solar energy. One step further goes one, if one integrates home battery storage. Then smart home also allows intelligent energy management , which makes you largely independent of the electricity supplier.

Experts say that Eiser’s profitability is 5% before the ICSID, compared to 7.3% of the reform

Experts say that Eiser’s profitability is 5% before the ICSID, compared to 7.3% of the reform

The experts of Brattle and BDO appointed in the international arbitration of the Ciadi against Spain about the cuts to the renewable facilities of Eiser Infrastructure Limited and Solar Energy Luxembourg calculate that the profitability of these investors was between 3.7% and 5%. % after the electrical reform in 2013, compared to 7.39% in the new legislation.

These considerations are included in the ICSID award referred to the parties last week, in which for the first time this institution pronounces on the cuts to renewable facilities in Spain, and does so in favor of the plaintiffs, who in In this case, they will be entitled to an indemnity of 128 million. The ICSID received about thirty complaints about this matter.

In the award, neither the expert appointed by the State’s attorney nor Eiser’s attorney included the economic returns of the plants in the percentage of “reasonable profitability” established by the Government. Brattle, designated by Eiser, figures the profitability of the solar thermal projects of the investor at 3.7%, while BDO, chosen by the State, does so at 5%.

“The real profitability before taxes of the plants is well below the target rate foreseen by the new regime,” says the award in view of these testimonies, before confirming that the Eiser facilities did not comply with the standard of “efficient” plants applied “retroactively” in 2013 by the Government.

In fact, the capital costs of the plants were about 40% higher than the level considered “efficient” by the reform. The complainant’s experts, from Brattle, attribute this difference to aspects such as the fact that the plants were owners, instead of tenants, of the land on which the projects were based.

The operating and maintenance costs of the plants also exceeded those considered efficient, even more so when in 2012 new taxes were approved that also levied the gas used by the solar thermal plants. As a result, the revenues of the facilities registered a decrease of 66% after the reform of 2013.

In 2014, one of the plants, Aires Solar, had operating income of 19.92 million, compared to the 27.76 million needed to respond to the company’s debts, while another facility, Dioxipe, received 7.79 million, against the 13.94 million needed to repay the debt.


The award shows precisely that the indebtedness of investors in renewables and their difficulties in repaying the debt after the cuts were not taken into account when defining the new remuneration regime for the reform.

In an interrogation, the director of the solar department of the Institute for Diversification and Energy Saving (IDAE), Carlos Montoya, confirmed that it was the Ministry’s officials who carried out the “estimations and crucial calculations” to define the remuneration standards “without take into account the real characteristics and production of the plants “.

“The new regime does not take into account the real costs, including the debt service, or the actual efficiencies of certain existing CSP (solar thermal) facilities,” the award states.

Montoya added during the hearing that he also used his personal knowledge based on a project or projects he had supervised, and “admitted in his testimony that the process was not based on a

Mathematical analysis of rigorous data, when stating that ‘if you look for […] an average or a mathematical formula, there is not one’ “, indicates the award.


The court ruling also describes the expectations on which Eiser decided to invest in renewables in June 2007. To do so, it carried out ‘due diligences’ and counted on the advice of Gómez Acebo

& Pombo. At that time, the main risk identified was that the project could not be built in the 36 months established in Royal Decree 661/2007.

The debt of the projects was equivalent to 70% of the capital in the case of the Astexol plant, and 63.5% in the case of the other two plants, known as Aste. In December 2011, Eiser valued its investments at 148 million euros.


The costs of the award, which include the fees of the arbitrators and court costs, amount to $ 956,159, of which $ 277,929 correspond to President John R. Crook, 177,439 to referee Stanimir Alexandrov and $ 123,964 to the other arbitrator, Campbell McLachlan .

The court has concluded that it is not the Spanish State that assumes the total cost, but that each party pays its own legal and other expenses, as well as the respective fee for the fees and expenses of the members of the tribunal and of the Accrued rights for the use of the ICSID.

Barcelona will assume the sewer rate of people in situations of energy poverty

Barcelona will assume the sewer rate of people in situations of energy poverty

The municipal government of Barcelona has proposed to assume the sewer rate of people suffering from energy poverty , which means between 10 and 15 euros per year of the water bill.

The City Council also plans to assume the debt in this issue generated by the citizens in precarious situation as well as the renewal of the Bulletin of Recognition of Electrical Installations.

These measures, however, will have to go through the commission and the plenary session first, but the Councilor for Presidency and Energy, Eloi Badia, has assured that all the groups agree so far.

Badia will also propose to the Àrea Metropolitana de Barcelona to do the same with the municipal rate of waste treatment. The mayor has taken the opportunity to criticize Agbar charged against the consistory for not doing homework in this area when he knows that they have been working to approve this initiative for five months.

This is a measure to exempt families in a situation of energy poverty from the sewerage rate included in the water tariff, an issue that serves 7,476 households, equivalent to 18,690 people.

This measure would imply about 100,000 euros for the City Council to assume the cost of the fee, which represents about 7% of the bill.

The water bill includes five concepts : this sewer rate, the supply, the water fee – which depends on the Generalitat -, the VAT and the waste treatment rate – of the Metropolitan Area of ​​Barcelona (AMB) – -, concepts that are grouped in the same invoice to optimize the administrative management, Badia has defended.


They plan to take a proposal to the metropolitan council of the AMB so that the waste treatment fee is not charged to these families in a situation of energy poverty, something that will also be addressed after the summer and that would affect the entire metropolitan area.

The AMB would cover what these families will not pay for the rate , which represents 14% of the bill, and advocate that both the supra-municipal administration and the City Council settle the debt in sewage and household waste that accumulates up to 1,000 euros.

The councilor has argued that “there will still be elements on the receipt on which it will be worth reflecting” and depend on other administrations : the VAT, which regulates the central government and asks to reduce, and the canon, which depends on the Generalitat, which is studying the matter, according to Badia.

Free security accreditation

The City Council has negotiated an agreement between the Energy Agency of Barcelona, ​​the Municipal Institute of Social Services and the Gremi d’Instal·ladors of Barcelona, ​​which establishes a protocol for families with difficulties not to pay for the Recognition Bulletin of Electrical Installations (Brie), required to change the contract or its owner.

Asked by the journalists, Badia pointed out that they have treated about 200 cases of families that have found themselves in the situation of having to pay for this document and can not afford the cost, since it costs about 100 euros, which the City Council will assume, with a approximate cost of 20,000 euros.

Months working with Agbar

He assured that the City Council has been working on this issue with Aigües de Barcelona for at least five months , and regretted that the society accused the municipality of not subsidizing the fees of its competition when it knew that the municipal government was already analyzing it: “It seems that the campaign has been more to dirty a measure that I think we should all celebrate. “

Badia, who voted against the accounts of Aigües de Barcelona, ​​has argued that the benefits should be used to lower rates, and Ortiz has asserted: ” We are talking about basic supplies , goods that are provided in other places as a common public service. We are not talking about buying and selling shoes, we are talking about having access to water “.

Energy advisory points

The Energy Advisory Points (PAE) have attended since 2015 to 4,626 households , added to those served by social services, reach 7,476, Ortiz detailed, which has explained that 1,921 supply cuts have been avoided and have been carried out 658 urgent interventions in homes with “severe deficiencies”.

Has specified that 75% of those served in the PAE are not users of social services , so he has asked the central government not to set this requirement to access social bonds, and noted that the advice points have driven some 50 community workshops, which aim to intensify during the summer, when energy poverty also influences health.

These ‘gadgets’ can save you a lot of money in electricity


These ‘gadgets’ can save you a lot of money in electricity

These days, receiving the bill for electricity means taking a hot flash. Prices have skyrocketed and it seems that they will stay very high for some time. More than ever, we need to save. We can make a conscientious consumption plan that keeps us vigilant about what we plug in or what we turn on … or we can leave it in the hands of technology.

The alternative is as attractive as it is effective. Every time more gadgets are released to the market with the aim of getting you to spend strictly what you need. We present some of the most innovative.


If you do not use it, turn it off

There are smart gadgets that are responsible for monitoring your cluelessness, as when you leave without turning off the light of a room or with a device on. Two very useful examples. The Ecobutton connects to the computer through the USB port and thus detects the time it takes without being in use. When it has exceeded the programmed minutes, it disconnects it. In this way, even the stand-by expense is suppressed .

Much more complete is the EnergyEgg , which consists of two devices: a motion detector and an adapter for the plug. When the set time is exceeded without activity in the room, the adapter cuts off the power of all the systems connected to that socket, but not before warning with a beep in case you want to cancel the action.


Remote control

From mobile devices we can know what happens in our house and make decisions that execute intelligent control systems. First example, the Xiaomi Smart Socket , in appearance a simple plug with adapter.

Through it you can connect any device to the network, with the advantage that it measures the consumption that is made and informs you of it in the mobile. Your app allows you to turn the device off or on remotely, or leave it programmed so that it can be connected in the hours when electricity is cheaper.

The Insight WeMo performs a similar function, with a couple of added advantages: it informs you when the devices have completed their function (the washing machine, the dryer, the oven …) to prevent them from being put on stand-by , and sends alerts if something it does not run as it should (a power failure, the washing machine stopped by a fault …).


Brains that think for you

The most complete gadgets are those that analyze the consumption of your home and advise you on how to reduce it. This is the purpose of Nubings , a system developed by three Galician physicists who, they say, can save 300 euros a year.

It consists of a small device that is installed in the electrical panel of the house and that connects with up to six circuits (plugs, appliances, lighting …). It is analyzing the peaks of consumption, the hours in which it is produced and in what it is spent more. With this information, it tells you through a mobile application if the electricity tariff you have contracted is the one that best suits you, where you have to cut back and if any device is inefficient.

Wattio and Mirubee , also Spanish systems, are the main competition of Nubings in this technological market of energy saving. All easy to install and with some prices (none costs more than 180 euros) that with the savings are amortized in a short time.
