We hear this mantra time and again. When it comes to carbon‹the "Most Wanted" element in terms of climate change‹nature has got reuse and recycle covered.

However, it's up to us to reduce. Scientists at Harvard Medical School are trying to meet this challenge by learning more about the carbon cycle, that is, the process by which carbon moves from the atmosphere into plants, oceans, soils, the earth's crust, and back into the atmosphere again.

Biofuels company Vireol is set to break ground in July on Britain's third major refinery making bioethanol from feed wheat and further expansion could be on the cards, the company's chief executive Dave Knibbs said.

"I think you could see some more plants here...We are the most efficient place to produce feed wheat in Europe, our yields are better than anyone else's and there is room for more growth (in yields)," he told Reuters in an interview.

TAU scientists create a solar energy device from a plant protein structure

If harnessing the unlimited solar power of the sun were easy, we wouldn't still have the greenhouse gas problem that results from the use of fossil fuel. And while solar energy systems work moderately well in hot desert climates, they are still inefficient and contribute only a small percentage of the general energy demand. A new solution may be coming from an unexpected source — a source that may be on your dinner plate tonight.

The ET-120 is billed as the first commercial hybrid two-wheeled vehicle. Designed for the crowded streets and limited budgets of India, it won't be setting any speed records (it tops out at 65 kilometers per hour), but the price is right at less than $1,000.

1366 Technologies hopes to cut the cost of solar with cheaper manufacturing.

A new manufacturing process could cut the cost of making crystalline silicon wafers for solar cells by 80 percent. The process is being developed by Lexington, MA-based 1366 Technologies, which this week showed off the first solar cells made this way. The technology is key to the company's plan to make solar power cheaper than the electricity generated from coal within 10 years.

An international research team has successfully sequenced the wild grass Brachypodium distachyon, a grass species related to major cereal grains like wheat, barley and oats.

A Hawaiian-based company is partnering with Hughes Hardwood, of Collinwood, to build a $200 million biorefinery in Wayne County, officials said.

The refinery, which will convert wood products into renewable diesel or jet fuel, will create about 50 jobs, officials said.

Canada’s battered forest industry continues to struggle with sluggish demand, pricing pressures from competitors in developing countries, bankruptcies, plant closures and job losses across the country.

Still reeling from continuous setbacks over the past five years—such as a drawn out softwood lumber dispute with the US—the sector is in dire need of a solutions in order to return to stability and maintain and support its workforce of 270,000.

Scientists are making progress in developing biofuels with a range of methods and an assortment of feedstocks.

Among the promising clean energy alternatives is an algae photo-bioreactor that grows algae in municipal wastewater to produce biofuel. Developed by the National Aeronautics and Space Administration (NASA), the bioreactor consists of large plastic bags made from a permeable "forward osmosis" membrane.
