SciAM: a path to sustainable energy by 2030

Supplies of wind and solar energy on accessible land dwarf the energy consumed by people around the globe.The authors’ plan calls for 3.8 million large wind turbines, 90,000 solar plants, and numerous geothermal, tidal and rooftop photovoltaic installations worldwide.The cost of generating and transmitting power would be less than the projected cost per kilowatt-hour for fossil-fuel and nuclear power. Shortages of a few specialty materials, along with lack of political will, loom as the greatest obstacles.
You may remember this article. We are swimming in excessive energy. Solar and wind are widely distributed and cannot be as easily controlled and profitized as plutonium radioactive energy can.

In December leaders from around the world will meet in Copenhagen to try to agree on cutting back greenhouse gas emissions for decades to come. The most effective step to implement that goal would be a massive shift away from fossil fuels to clean, renewable energy sources. If leaders can have confidence that such a transformation is possible, they might commit to an historic agreement. We think they can.

A year ago former vice president Al Gore threw down a gauntlet: to repower America with 100 percent carbon-free electricity within 10 years. As the two of us started to evaluate the feasibility of such a change, we took on an even larger challenge: to determine how 100 percent of the world's energy, for all purposes, could be supplied by wind, water and solar resources, by as early as 2030. Our plan is presented here.

The only sustainable energy source humans have access to is nuclear.
