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.
