Study says wind could power the whole world
WASHINGTON (AFP) - There's enough wind to power the world many times over, according to a study out on Monday, but it would take a massive infrastructure investment to harness it that analysts say is not realistic.
As the world seeks to lessen its reliance on fossil fuels like coal and natural gas, renewable energy sources like wind and solar power are being developed as alternatives.
Contrary to some other recent studies, analysis of climate data in the Proceedings of the National Academy of Sciences indicates wind turbines could harness hundreds of terawatts of electricity, far more than is needed to power the globe, even when accounting for the interplay between the groupings of turbines in so-called "wind farms". To reach that maximum potential, according to study author Mark Jacobson, it would require 1.5 billion massive windmills to be installed on and offshore.
That's far more than you would need to meet the world's actual energy demands, the Stanford University engineer qualified, but you would still need many millions more turbines than currently exist.
