Renewing Our Energy Future

Evaluates the potential for cost-effective renewable energy in the coming decades and the actions that have to be taken to achieve the potential. Some applications, especially wind and bioenergy, are already competitive with conventional technologies. Others, such as photovoltics, have great promise, but will require significant R & D to achieve cost-competitiveness. Covers: agricultural energy crops; residential and commercial buildings; transport; electricity; technology development, and market challenges; and government supports and international competition.
