Dragon and the Sun
I normally get annoyed with alternative energy projects, mainly because most of them have negative EROI (Energy returned On Energy Invested) meaning they actually INCREASE our addiction to fossil fuels. Basically, most "green alternative" power plants take so much oil and natural gas to build that in order to pollute the planet less and conserve more of the precious fossil fuels it would have been better to never to build them.
However, Spain has actually done something truly praiseworthy and build a genuine, Energy-positive power plant:
"It is Europe's first commercially operating power station using the Sun's energy this way and at the moment its operator, Solucar, proudly claims that it generates 11 Megawatts (MW) of electricity without emitting a single puff of greenhouse gas. This current figure is enough to power up to 6,000 homes.
But ultimately, the entire plant should generate as much power as is used by the 600,000 people of Seville."
This still will not be the solution to end our energy woes, as the silver required to build the mirrors is far too rare, but it is a promising first step.
