: "Enabling Innovation is an engrossing look at some of the disaster - and success - stories surrounding technological development and diffusion in industrialized and developing countries. The book tells the story of widely divergent technologies - agricultural appliances, wind turbines, Green Revolution high yielding seeds, the Linux computer operating system, and Local Economic Trading Systems. Boru Douthwaite has constructed a "how to do it" guide to innovation management that runs counter to so many current "top-down", "big is good", and "private sector is best" assumptions." The author is a CGIAR scientist. The book is a well-written and brief. Recommended. [amazon

Wind power majors see growth in India:
"Two of the world's leading wind turbine makers Danish Vestas and NEG Micon are both expecting strong growth in India, the fifth biggest wind power market in the world. "India will be a very important market in the years to come. I think we will see market growth rates of at least 40-50 per cent annually," Rakesh Bakshi, managing director of Vestas RRB India. " Bakshi projects 6-7000 MW sales for the industry in the next 10 years. 8:55:03 PM
Calculating electricity GHG impact: In a story about the Nature Conservancy's plans to procure renewable power for its HQ, some interesting statistics were offered. The HQ uses 4,000,000 kwh per year, of which 10% will soon be from renewable sources. A number of equivalents were derived:
- A typical home uses 10,000 kwh/year (ie, 10 Mwh)
- Each Mwh emits 1,600 lbs (or .75 metric tonnes) of CO2
- A typical car emits 10,000 lbs (or 4.5 metric tonnes) CO2/year
- An acre of forest absorbs 7,300 lbs (or 3.3 metric tonnes) CO2/year
- A typical home emits 60% more CO2 than a typical car each year
- A typical car's emissions are absorbed by 1.4 acres of forest
- A typical home's emissions are absorbed by 2.3 acres of forest
Norway's Statoil studying Iceland power exports
: "Under the plan, geothermal energy from a depth of 1,000-2,000 metres would drive turbines tied to electricity generators. It said that a [600 MW] power station would generate about five terawatt hours a year, or 4-5 percent of Norway's annual hydropower output. If the plant were built, a submarine power cable about 1,200 kms (745.6 miles) long would have to be laid, either to Britain or Norway or to both. Transmission losses over the cable would be about six percent." The feasibility study is scheduled to complete early 2003. 2:13:08 PM
UK Offshore Wind Technology Funded: "Two new plans were given the green light last week, with the promise of £20 million (US$31 million) of government support. .. The development by National Windpower will result in 30 wind turbines with a total capacity of up to 90 MW. The Powergen project off Norfolk will consist of 39 turbines with a total capacity of up to 80 MW." 2:02:07 PM
North Sea wind farm built
: "Work to install a 160 MW wind farm at Horn Rev
in Denmark was completed in August by Danish energy company Elsam. .. At present, four wind turbines have been commissioned. All 80 wind turbines of the wind farm should be in operation in mid November 2002. " 1:59:54 PM
