such as oil, coal, and natural gas. That massive fossil fuel consumption produces some nasty side effects, including climate change, acidified oceans, and oil spills.
These problems are likely to grow far worse in coming years, as worldwide energy use is expected to at least double by 2050.
Renewable power sources, such as solar photovoltaics and wind turbines, aim to fill this demand, and they are making steady progress at providing electricity at ever cheaper costs. But electricity has a key drawback as an energy carrier. It’s difficult to store in large quantities, which means it can’t be used for most heavy industry and transportation applications, such as flying planes or driving heavy trucks. So researchers have long sought to use the energy in sunlight to generate energy-rich chemical fuels, such as hydrogen gas, methane, and gasoline, that can be burned anytime anywhere

!! Windpower Could Provide 40 Times Earth's Power Needs !!
If that area on picture, size of Austria, was covered in solar thermal power plants, it would produce enough electricity to meet WORLD demand ... hard to believe, but that's what exactly it is.
Smaller red square area covered with soalr power plants would satisfy electricity needs of Europe, the smallest one would cover Germany's energy demand...
