Amid all the doom, gloom, and denial, here comes a book that promises some good news regarding viable energy resources in the age of climate change. Groundbreaking environmentalist and founder of the Earth Policy Institute, Brown extols the virtues and possibilities of wind and solar power, and supports his advocacy with hard facts, concrete examples, and surprising statistics. The conversion from fossil fuels and nuclear power to renewable and inexhaustible energy sources has already begun. In the U.S., states such as Iowa and South Dakota are procuring large amounts of electricity from wind farms, while others, such as Massachusetts, have a firm deadline for going off-grid. Such a transition from one source of power to another is not without precedent; after all, it was only 150 years ago that the first oil well was drilled. By carefully analyzing policies and practices already in place around the world, Brown and his team of researchers demonstrate that new energy sources will be commonplace sooner than we think.
