In the United States, the development of biofuels has been presented as a potential way for America to become less dependent on foreign oil, while at the same time reducing greenhouse gas emissions. Both of these potential benefits are appealing, but the feasibility of biofuels, from both scientific and economic perspectives, is still an open question and much debated. In December, President Bu...

Biofuels; Microbial fermentations; Ethanol; Biodiesel demand by emerging economies and the recent increases in global oil prices. Multiple approaches are currently being researched for the use of microorganisms in the production of various biofuel (e.g. alcohols, hydrogen, biodiesel, and biogas) from multiple starting materials. This review provides a brief overview on the research currently un...

Introduction In 2007 the Energy Independence and Security Act (EISA) established that by 2022, 36 billion gallons of biofuel are to come from renewable fuel sources. More specifically, the mandate requires the production of cellulosic biofuels to increase to 16 billion gallons ethanol equivalent annually by 2022 (Energy Independence and Security Act, 2007). Cellulosic biofuels are derived from ...

Philip Martin....................................9 Any game works better when the rules are enforced consis­ tently, whether it is the Superbowl or Monopoly around the kitchen table. If the referee is indecisive, then the players are uncertain about how to play and the game degenerates. Transportation fuel markets in the United States currently resemble a game with inconsistently enforced rules...

of FITs, Q-cells became one of the fastest-growing companies in Europe, and is now the second largest manufacturer of photovoltaic cells in the world, surpassed only by the Japanese electronics giant Sharp. And this growth continues unabated. For the first quarter of 2007, Q-cells reported a 43 per cent year-on-year increase in sales, and a 45 per cent increase in production. The output stands ...

 Algae can provide a variety of fuels for transport, heating or electricity generation, including biodiesel, aviation fuel and biogas.  Algal biofuels are at an experimental stage and are more expensive than fossil fuels.  Algal biofuels could be made more costeffective by extracting other valuable products from algae or incorporating their production into waste water treatment.  Commercial...
