Alternative energy, once the domain of hippies and off-the-grid fringe enthusiasts, has gone mainstream. Although technologies such as solar and wind power, plant-based fuels such as ethanol and biodiesel, and "green" buildings have become hip because of environmental awareness and global climate change, the real reason behind their increasing profile is economics.
When clean energy sources begin to rival more traditional ones on a cost basis, which is beginning to happen now owing to advances related to the microchip and economies of scale, corporations will quickly begin to take notice. Although Pernick and Wilder state that they are not financial advisors, they profile the leading companies involved in the most promising of these alternative energies, which gives the reader a place to begin doing further research into investment opportunities. The book is an excel
lent update on the current state of the industry and a who's who of the companies poised to profit from this exciting array of technologies.
