Cleantech: Biodiesel, Solar and Wind
Some news today highlights Biodiesel, solar and wind technologies in the era of cleantech and renewable energy.
The first article discusses a study that was just completed in Ontario, Canada that analyzed the use of biodiesel as an alternative fuel source for agricultural use. This study, which was co-sponsored by the NRC, Environment Canada, Agriculture and Agri-Food Canada, the Ontario Soil and Crop Improvement Association, UPI Energy, and the University of Guelph, is hoped to accelerate the adoption of biodiesel use in on-farm applications across Canada.

Solar power seems to still be behind in the race for the most cheap, and efficient technologies despite being around for a number of years. There are a few problems that need sorting out (listen here scientists, and business-types), “the development of complimentary technologies, in particular low-cost storage of electricity, is critical,” says Erin Baker, who is a scientist at the University of Massachusetts that led a USDoE study in the area. Baker’s other finding notes that government dollars won’t bring this technology to fruition along, and that private investment is needed in the manufacturing sector specifically; tax breaks, and public-private collaborations will also help to push this technology forward. The article “Cheap, Efficient Solar Power: What’s Needed Now To Get There?“ gives a great analysis that discusses the order of investment to develop solar tech:
- Focus first on getting power from the new inorganic materials that show promise but are far from viable for large scale production
- Then focus on purely organic cells with organic semiconductors; these hold the promise of low costs but still haven’t achieved high levels of efficiency and face serious stability problems
- Last, investigate third-generation cells, which use entirely different technology but may ultimately yield much more power
Wind turbines are another fast-moving technology with much promise. So much so that Mitsubishi Ups Investment in Wind Turbines threefold to increase its wind turbine capacity to 1,200 megawatts / year by March 2009. As Paul Kedrosky points out, that is about two-thirds of what the city of Atlanta requires on a typical summer day.
