Commercial flower and plant growers know all too well that invasive, ubiquitous weeds cause trouble by lowering the value and deterring healthy growth of potted ornamental plants.

University of Maryland research that started with bacteria from the Chesapeake Bay has led to a process that may be able to convert large volumes of all kinds of plant products, from leftover brewer's mash to paper trash, into ethanol and other biofuel alternatives to gasoline.

The Kroger Co., VeraSun Energy Corp. and Enterprise Rent-A-Car announced several moves Tuesday to make VeraSun-branded VE85TM ethanol an easier choice for rental customers.

In a finding that could help put wheat alongside corn on the menu of biofuel sources, researchers in the United Kingdom and Greece report development of a new method for producing ethanol from wheat.

The future of biofuels is not in corn, says a new report released today by Food & Water Watch, the Network for New Energy Choices, and the Vermont Law School Institute for Energy and the Environment.

With U.S. biodiesel production at an all-time high and a record number of new biodiesel plants under construction, the industry is facing an impending crisis over waste glycerin, the major byproduct of biodiesel production. New findings from Rice University suggest a possible answer in the form of a bacterium that ferments glycerin and produces ethanol, another popular biofuel.

The hydrogen economy is not a futuristic concept. The U.S. Department of Energy's 2006 Advance Energy Initiative calls for competitive ethanol from plant sources by 2012 and a good selection of hydrogen-powered fuel cell vehicles by 2020.

The ethanol boom could dramatically impact natural gas prices. Some analysts are predicted a natural gas demand increase up to one percent from the ethanol boom. But their estimates do not include increased fertilizer demand to increase corn yields.

As the United States looks to alternate fuel sources, ethanol has become one of the front runners. Farmers have begun planting corn in the hopes that its potential new use for corn will be a new income source. What many don't realize, is the potential for other crops, besides corn, to provide an alternate energy source to fossil fuels.

Rising world oil prices have sparked interest in alternative fuels, such as ethanol, which can be produced from corn. This has raised demand for the grain, which, in turn, has increased its price as food. VOA's Peter Fedynsky reports that higher prices may not be the only cost associated with corn-based ethanol.
