...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...
...above corruption, crime and access to capital as the biggest obstacle to budding entrepreneurs in Africa. "It saddens me when I come to a place where you have a big oil-driven generator sitting on top of a geothermal field and you're paying three or four times the cost [for energy]," says Thoroddsson, the former CEO of Reykjavik Energy's investment...
...least 20% of annual global carbon emissions come from deforestation. If we can't stop forest loss, we'll struggle to stop climate change. That fact was recognized by the British government's recent Eliasch Review on forestry, which estimated that failure to halt deforestation could increase the cost of damages caused by global warming by $1 trillion annually by 2100. "If we're going to solve climate change we need to take advantage of the opportunity to reduce deforestation," says Duncan Marsh, TNC's director of international climate policy. "We have no choice." That's the promise of avoided...
Business is starting to catch on, too, not least because of the potential long-term cost savings. While the initial investment in new digital lighting is steep, the long life of the lights means that it can be a smart one-time buy. In Britain this year, supermarket giants Tesco and Sainsbury have both announced plans to substitute fluorescent with LED lighting in their freezer sections. Hotel chains are also making the switch...
...Hawaii Governor Linda Lingle and her state's largest utility endorsed plans to build more than 70,000 recharging stations for electric vehicles by 2012. The project, expected to cost upwards of $70 million, calls for a public-private partnership with the California-based battery maker Better Place, which will build the stations and supply batteries to those who choose to buy or lease an electric car. Lingle hailed the plan as a major step in curbing emissions and rising energy costs. The state needs to do something; it spends nearly $7 billion each year on imported oil. Better Place...
