Biofuel Bugs

As we know, nowadays the non-renewable resources such as petroleum, coal and others are getting less and less. Recently, I have read about biofuel bugs. The researchers at the Biodesign Institute have found a new source of renewable energy which is bugs. Like plants, these microbes use energy from the sun to grow and scientist have found that the fat by-products can be used to make high energy fuel such as biodiesel. It's an appealing alternative to biofuels that come from corn, soybeans and switchgrass which can divert land away from food and feed production and are sometimes processed in coal burning plant.
