The book Clean Money: Picking Winners in the Green Tech Boom by John Rubino, goes into extensive but easy to understand detail about all the various types of green industries, including solar energy, wind power, geothermal, green transportation, biofuels, pollution control, and much, much more. This book has a lot of 'meat'. What that means is that it lists thorough descriptions of various individual stocks in each type of green industry. It even covers foreign green stocks. Even though the price of oil has dropped significantly since the book was written, it is still very useful in finding the best stocks in the alternative energy industry, which many analysts believe should do well under Obama. I recommend this book as an interesting read and a great resource.
