Vast amounts of solar energy radiate to the Earth constantly, but tapping that energy cost-effectively remains a challenge.
Where the wind blows
How far can wind power go toward reducing global carbon emissions from electricity production?
What can make a dent?
Given the enormous scale of worldwide energy use, there are limited options for achieving significant reductions in greenhouse gas emissions.
