...addition, small-scale turbines installed in cities have lower productivity due to interference and intermittent wind, according to a recent report released by the Carbon Trust, a British-funded group that helps companies reduce their carbon emissions...
...prospective wind turbine installations are part of a larger campus focus on sustainability and carbon emissions. In an announcement made earlier this summer by Faust, committed Harvard to reducing its greenhouse gas emissions 30 percent below 2006 levels...
...food crisis and endangering the planet. Now imagine the public relations nightmare facing an oil company that uses technology responsible for powering Nazi Germany, that propped up apartheid for decades and that operates a plant with the dubious distinction of being the world's biggest single-point source of carbon dioxide. Only a die-hard optimist could talk up such a company, right? Meet Pat Davies, head of South African energy giant Sasol, and listen to him speak about its prospects. "We're coming into a sweet spot, a unique position," he says with a calm, easy smile...
...business. Sasol's end product is cleaner than the average diesel fuel or gasoline, emitting less sulfur and less nitrogen when it burns, says Barrows. Coal-to-liquid plants can also be used to clean up the mountains of coal left over at old mines. But in terms of carbon emissions, Fischer-Tropsch is dirty. A sliding scale of emissions from fossil fuels, goes: coal, petroleum, methane. Coal emits the most carbon dioxide per unit of energy obtained. The resultant fuel also emits more carbon dioxide when burned. "It's a double whammy," says Barrows. Ricketts cautions that Sasol...
...energy company like Sasol to thrive using current technology, "public opinion would have to decide carbon emissions are a necessary evil to bring down the cost of fuel in the short term until more sustainable sources of fuel are discovered," says Barrows. Krupp is blunter. "In order for Sasol to have a profitable future, we have to be cynical about the world's ability to save itself," he says. But Sasol is used to these kinds of dilemmas. "There is a tension here," Davies acknowledges. "All development makes pollution. But China and India want what the West has, so they...
