You may have to look hard, but some very smart companies are doing some very creative things when it comes to the environment
But that doesn’t mean biofuels can’t play a major role in a greener U.S. energy policy — they just have to be the right kind. One of the best options on the horizon is biofuel made from algae, which counters a lot of the problems with corn ethanol. (The right strains of algae secrete oils that can be used to make fuel.) Algae do not need farmland to grow: tanks will do the job just fine anywhere there is spare land and a decent amount of sunshine. Algae also grow much faster than traditional crops, and the micro-organisms may be able to use to use wastewater or even saline water during their development, rather than fresh water. Startups like Sapphire Energy and Algenol in California and Florida are passing the pilot phase and nearing commercial development; they just need a little government help.
