...Mission Over the years, Icelandic engineers have learned which temperature enables underground liquids to power a turbine, how to manage a boiling cavern's chemistry, and how to keep power plants sustainable by "resting" boreholes to give the source time to replenish its heat. While the ongoing costs of a geothermal power plant are low - Krafla, for example, has only 15 full-time employees - the start-up technology needed to extract heat from a few miles beneath the earth's surface and convert it to electricity is not cheap. By some estimates, conducting the necessary geologic surveys and exploratory drilling...
...company is focusing its early investments on East Africa, an area with vast amounts of underground heat and little means to tap it. The company plans to start exploratory drilling next year to build a geothermal plant in Djibouti. In July, the government of the Philippines awarded a Filipino-Icelandic consortium exploration rights to half of Biliran Island in the country's south. Twenty years ago, three boreholes were drilled on Biliran and then abandoned when the underground liquid at the other end of the drill was found to be too acidic. Since then, the industry has learned...
...tropical forests and the pace of climate change - if we can get it right. An estimated 50,000 sq. mi. (129,500 sq km) of forest are lost to the logger's ax or to fire every year, and that hurts the planet in two very important ways. Rare plants and animals, many still undiscovered, depend on the forests - especially the rich rain forests that encircle the earth either side of the equator. When the forests disappear, all that wildlife disappears as well. But trees also contain carbon, and while they live, they absorb CO2 from the atmosphere, compensating...
...industry has been extremely proactive," says Russill of the Energy Saving Trust. Philips is making some of the biggest bets. Over the past two years, it has spent more than $4 billion on acquisitions aimed at positioning itself as a leader in digital, low-energy lighting. The plant outside Antwerp belonged to the consumer-lighting market leader Partners in Lighting, which Philips bought in 2006. The company followed that purchase a year later with the $2.7 billion acquisition of Genlyte, a big U.S. player that makes lights for offices, highways, factories and outdoor advertising. Those deals come...
Among the more serious complaints against the plant proposal was its potential danger of disrupting local bird and fish habitats, but recently, even the U.S. Fish and Wildlife Service has determined that the wind farm will not be detrimental to either. Moreover, this has not been the only outside body to support this project: The Audubon Society, a national wildlife conservation group, has also given Cape Wind its backing...
