Solar panels to power the entire earth
Efforts in favor of clean energy they are still cautious and discreet, but still draws a future where oil, coal and natural gas become less necessary.
A timely article by TreeHugger announced that manufacturers of solar photovoltaic cells increased their production by 51% in 2009. And while the growth was even higher in 2008, the fact that in recent months have produced more than 10,700 megawatts of solar cells worldwide indicates a foothold in the right direction. A production of these characteristics can power about 5 million homes and today the sun’s energy to reach 100 countries.
Even better news is that renewables are not only a matter of individuals and households, companies also began to soak up sun, and now Walmart, supermarkets and chain stores, announces it will install solar panels between 20 and 30 stores in California and Arizona.
Walmart has hired the firm SolarCity for designing, installing and maintaining solar energy systems that cater to their huge business in 20-30% of the total energy need. Rather than buy the panels, the energy service contract WalMart, as if it were a utility.
For experts it is crucial that the chain has decided to use the services of a leading solar energy, which speaks of his efforts are not just about image but also the safety and long-term commitment to energy revolution.
And while a solar panel no longer a technology somewhat inaccessible to most citizens of the world, energy-saving alternatives begin to be at hand. What are yours.
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.
Rio III: Want to make solar energy in public
The municipal government of the city of Rio Tercero launch in the coming days the “Green Power”, which aims to install solar panels on several municipal public schools. The first stage involves the use of solar energy to heat some municipal buildings, replacing gas or electricity. Then bet that is used as the sole source of energy in these departments.
The first experiment was to open in December in one of the neighborhood health centers, located in Monte Grande Park neighborhood. In that building, which lacks natural gas, will install 12 solar panels that provide hot water, heating and air conditioning. This initial investment will be 40 thousand dollars.
According to Mayor Luis Brouwer de Koning, the idea is to install in several municipal system. He argued that besides being “clean energy” mean a reduction in fixed costs of energy. He said it also plans to move this system to supply the demand side of the municipal building, and set the criterion that each new municipal building to be built admire this innovation.
Spain became a leader in solar energy
China, which enjoys an incredible global financial assets that ranked as the world’s second largest economy. Or in continental terms, European is what develops further action and investment in clean energy. However, even in crisis, Spain has managed to sign up as a reference in the matter, because today is a leader in solar energy.
After a hard work and by good growth policies, Spain surpassed the United States became the world’s largest producer of solar thermal energy, creating an installed capacity of 432 megawatts (MW), 10 more than Americans.
The achievement was made possible due to the thermal plant “Florida” in Badajoz, most other plants that produce record capability on the mainland. Among all plants make up a territory in excess of 550,000 square meters to capture solar energy has been become the largest in the world among the plants in operation.
Inevitably, the world’s leading nations have begun to invest and set plans in renewable energy. The oil reserves are not eternal and an estimated remaining oil for thirty years at peak production and then begins to decrease. That is why new renewable energy sources are the main stake in Spain, has started positively.
The solar energy is produced through the use of the sun’s energy for heat and for the production of mechanical energy and then electric.
