Restaurants that use solar energy
Located in Chile’s Elqui Valley, north of Santiago, Villaseca Solar gathers a group of families with the help of the University and a section of the national government have managed to reverse the situation: whereas previously they had to fight for firewood and being able to cook with solar cookers the development of the site now forms a renowned restaurant offering international dishes produced from renewable energy sources.
The history of the Solar Villaseca is so interesting and attractive as the productions they do it: Before this initiative, the place was an area of ??extreme poverty. Through aid programs, families were able to get some solar cookers for heating water. Excited about this new possibility, the people they came to go further: this renewable energy source could cook up to create the only restaurant in the country that works entirely with solar energy.
Thus arose Villaseca and today the town is news to national and international level.
The particularities of the Elqui Valley help achieve this type of production with solar cookers: here the sun shine on the town almost every day of the year. Thus, the ten ovens working all day to serve about 70 people.
While it is not possible to offer the widest variety of dishes due to this particular form of development, the fact is that you can enjoy the most diverse vegetable salads and casseroles with various meats and poultry.
Meeting point for both local and national and international tourists, Villaseca today is an example of social and green micro-initiatives that are worth playing.
Attempts to inflate the reality of clean energy
The development of clean energy is an increasingly tangible reality in different countries around the globe. Believing in the not too distant future the entire planet’s electricity could be produced without the use of fossil fuels, countries like the United States recently announced its plan to incorporate new technologies and so develop more alternative sources.
In line with these proposals, the protagonist is now Uruguay, which made ??further announcements regarding the production of clean energy. The government’s goal is to advance the development model to arrive at 2015 with 50 percent of its electricity from renewable energy.
To comply with the proposal in just four years the country would be carrying out the goal of the Energy Policy 2015-2030, which states that 50 percent of total energy matrix should come from renewable sources.
Other initiatives set forth in this program include the treatment of 30 percent of aggro-industrial and urban waste to generate energy, a 15 percent reduction in oil consumption of transport and that the scope of electricity within the country is a 100 percent.
As explained from Discover the Verde, the immediate projects to achieve the increased power of this type consist of the installation of wind farms, which come to provide a total of 500 MW. This is an important advance in clean production. Energy efficiency is becoming a priority in the agenda of many countries, this being beneficial to the environment and social and economic development locally and globally.
How to increase the use of clean energy
The rise of the Internet, new media and social networks often makes us think we connect, share and be part of the digital universe is cheap, simple and harmless.
Fortunately Greenpeace always on time to show our true relationship with the planet: the campaign “Unfriendly Coal” (or “Do not be a friend of coal”) was created to encourage users of the Facebook social network – and from that to the social network itself – to become aware of the enormous energy demand required to operate and how this non-renewable energy use promotes global warming.
The campaign is based on the release of ads (for a recent TV ad) and dissemination of a Facebook page that is close to 100,000 fans. The ultimate goal is that Facebook is committed in this upcoming Earth Day to become green.
More specifically: to increase the use of clean energy, to develop a plan to abandon the use of energy from coal by the year 2021, that educates users on energy and carbon footprint and to defend this type of clean energy level local, national and international levels.
Solar tower 140 meters high which produces about 392 megawatts of electricity
The company Google is working on an ambitious new project known as Ivan pah. This is a complex located in the Mojave Desert, California, where thanks to a solar tower 140 meters high will generate about 392 megawatts of power.
The initiative, managed by the company Bright Source Energy and built by Bechtel, is a space with three plants that generate electricity for 14 000 homes in California thanks to its structure were used to capture 173 000 hemostat solar energy.
Construction began in 2010 and is expected to be completed in 2013, creating numerous environmental and social benefits. As explained from Bright Source Energy, the project will prevent the emission of 13.5 million tons of carbon dioxide (CO2) over a period of thirty years. In addition, it will generate more than a thousand new jobs and give a major economic boost to the region.
For the realization of Ivan pah, Google has already invested 118 million euros. This initiative is in addition to others developed in recent years, where the company seeks to manage renewable energy to demonstrate its commitment to the environment and society.
It is essential that large companies are responsible for a large part of greenhouse gas emissions, is tipping towards sustainable development to curb the impact of their activities. For Google this is just the beginning and is still a long way to go.
Center for the Study of energy development issues at the Villa Maria
Representatives of the company Enarsa decided advance in the realization of a poryecto designed to enable in this city a center of study and development of renewable energy. In principle, participate in the development of the proposed addition to the local municipality and local universities Enarsa with six companies in Argentina, Latin America and Europe.
In this sense, it made the filing Tuesday of studies conducted by the listed firms for the implementation of wind farms in the Corridor area Achiras-Villa Maria. The research took shape after the Province of Córdoba progressed into an agreement with Enarsa on joint action to determine the quality of the winds and the feasibility of development investments.
It must be said that companies participating in this initiative are Bibi, of Argentina; Gralco, also of Argentina, but with Italian technology; Alusa Brazil; Radiotromix-Ezentis Wpd Spain and in Germany. It is noteworthy that the sum of proposals would generate 260 megawatts Achiras with an investment of 560 million dollars and 4 to 6 megawatts for the city of Villa María.
In the local case, we evaluate the utility is for scientific and technological development for both students and professionals involved ara Center for the Study and Development of Renewable Energies.
Plans to make energy for the entire world in 2030
Resource depletion and pollution generated by this method is causing a real shift towards forms of production related to renewable energy.
Wind, earth, sun and sea are gaining prominence as clean sources in the not too distant future completely displace the traditional power grid. Experts say the change could occur in just 20 years and reach 2030 without the need for fossil fuels and continue to emit millions of toxic gases into the atmosphere.
While it really looks like a utopia, the study by Mark Delucchi and Mark Jacobson recently published in the journal “Energy Policy (Energy Policy) argues that clean technologies developed so far (wind, tidal, solar and geothermal) are capable of transforming entire global energy production.
As explained from Inhabitat, the numbers published in the report are staggering: a civilization with 100 percent renewable energy should be thought of 90 000 solar power plants of 300 MW, 1.7 billion of rooftop solar panels and 3 KW 4 million wind turbines of 5 MW. All this would require new infrastructure and radical changes in several areas as it would be transport, where vehicles should run entirely by renewable fuels and batteries.
While all this seems unattainable in such a short time, the study serves to demonstrate that more can and must turn to a more sustainable development. The change is already tangible in many parts of the globe where every day is starting new projects related to renewable energy. Only to invest more efforts and work in a global commitment to policies that lead to new initiatives and make them effective in different parts of the world.
The project created a bridge with wind turbines solar panels
Cars that run on biofuels, roads, airplanes and solar boats. Around the globe are increasingly exposed innovative proposals related to the production of renewable energy.
On this occasion, the news comes from southern Italy, near Calabria, with an interesting green project called “Solar Wind.” This is a bridge that was to be destroyed but which required demolition of at least $ 50 million, so the authorities proposed to reuse the structure so friendly to the environment. To do this, it will install 26 turbines in place, granting power to the road of 200 meters of solar panels.
According to Inhabitat, the project was designed by Francesco Colarossi, Giovanna Saracino Saracino and Louise, after winning the “Solar Park South” proposed by the local government.
Thanks to the implementation of wind energy would produce 36 million kilowatt hours annually, while solar panels would do the same with an output of 11 million kilowatts / hour. As a result, the bridge could generate electricity for about 15 thousand Italian households.
In addition, it is intended that the place where this old overpass worked to become a public attraction, with incredible views and the ability to show thousands of citizens the benefits of producing environmentally friendly way.
What at first thought that would be just rubble, today becomes a potential source of energy. This is a proposal can be replicated in different parts of the world thanks to its economic and ecological benefits.
The positive effect obtained from wind energy
The fact that wind energy now plays a leading role in the country’s energy supply should not be an obstacle to their development. Supporters of the facilities producing electricity from wind power can breathe a sigh of relief.
“The ridges of the Jura and remain accessible to the wind,” says Fernand Cuche, State Councilor (Senator) in Neuchâtel the Green Party. In late August, the Federal Court (TF) had accepted an appeal by the developers of a project to build seven plants in the area of the View of the Alps in the canton of Neuchâtel.
A negative response to Switzerland’s Supreme Court would set a final deadline for the development of wind farms in Switzerland.
A negligible contribution
To understand the scope of this decision, we must look back. In March 2005, the Administrative Court of the Canton of Neuchâtel had received an appeal against this bill, introduced by some locals, supported by the Swiss Foundation for Landscape Protection and the Swiss Heritage Association.
Neuchâtel judges considered that protection of the landscape – in this case the ridges of the Jura – was prominent in view of the contribution “weak if not insignificant” wind energy to supply electricity in the country.
“We can not keep any money a form of energy that can be justified anywhere else but in Switzerland it is hardly conceivable. There is enough wind in our country,” said Richard Patthey, secretary of the Swiss Foundation for Landscape Protection.
A shared argument
This kind of argument, however, was not shared by the Federal Court. Its five judges stressed that the fact that wind energy contributes to reduced energy supply can not be considered as a “decisive.”
The roof of the house that reduces energy use
These ingredients are energy efficiency, interior comfort and use of renewable energy. “In VELUX we join the interests of institutions and companies committed to sustainability and social responsibility, values that are the basis of our work. We are pleased to contribute to research and develop new solutions to achieve optimal levels interior comfort with minimum energy consumption.
In this new target VELUX launches two new initiatives: the first window of solar-powered roof, a product that makes use of current technology to improve comfort below deck and energy savings, and a new power-saving function, built in the remote window and solar power, which activates automatically the blinds and mosquito nets to protect from the sun at times of higher radiation.
Window solar-powered roof, transform solar energy into electricity through a photovoltaic cell located, quietly, at the top of the window. Both battery that stores electrical energy as the engine, are perfectly integrated into the window frame.
In addition, VELUX offers a handy kit that lets you convert a manual window opening in a new window powered by solar power easily and without cables.
The other new solution is the “Power Saver”, entered in the command window and solar power are a number of variables that take into account the local average temperature, orientation of windows, location, etc … building a tailored suit every home. When the program has been activated, the script automatically starts the predetermined times. The times have been established for sunscreen products (blinds and mosquito nets) will raise or fall depending on season and time of day.
For example, during the summer in southern sun protection products will be lowered at a specific time in the morning and evening rise, and vice versa in winter. Furthermore, control automatically distinguishes between weekdays and weekends.
How energy-efficient devices for electrical development
“In less than ten years i.e. in 2018, the incorporation of energy efficient devices could slow the growth of electricity demand, achieving reductions in the order of 600 megawatts (MW),” said the Directorate General for Energy Efficiency (DGSE), Ministry of Energy and Mines of Peru (MEM).
The head of the DGSE, Luis Hero, said this would not be the only benefit, as this would also avoid the emission of 35 million tons of greenhouse gases produced by burning fossil fuels for electricity generation.
Wall
And is that because the country’s energy supply by 73% dependent on fossil fuels such as oil (51%), natural gas liquids (17%) and coal (5%), which are being looking not only pollutants but also expensive because they depend on international prices, the DGSE has designed a plan to boost renewable energy sources and energy efficiency.
He explained that energy efficiency itself constitutes a new source of energy as to reduce the volume of current consumption would also reduce the amount invested to import oil.
That is why he said Hero Azalea, projected that the sector as part of an ongoing process to improve the activities related to the generation / production, transportation, processing, distribution, marketing and use of energy sources over the next eight years could reduce national energy consumption by 15%.
“Making a calculation based on current, we can see that the annual savings to be gained in 10 years would be approximately 5 000 300 million U.S. dollars, with an estimated investment of 670 million U.S. dollars (an approximate ratio of 8 to 1)” said the head of the DGSE noting that the benefits go to the care of the environment.
