advanced biofuels
Here are two very different advanced biofuel strategies: Green Plains Renewable Energy, Inc. (NASDAQ: GPRE) is producing algae from byproducts at one of its commercial ethanol plants to make biodiesel, and Codexis, Inc. (NASDAQ: CDXS) is developing biocatalysts to produce advanced biofuel and pharmaceuticals and to remove carbon from smokestacks.
The oil industry has backed off alternative energy investments in recent months. BP, for instance, made news in April when it cut 620 jobs of an original 4,400 in its solar business. Last October it killed a $67 million expansion of its solar manufacturing operation in Maryland.
U.S. President Barack Obama's administration issued a draft rule to slash the greenhouse gas emissions of biofuels, but confirmed former President Bush’s commitment to produce corn-based ethanol.
