CleanTechies joined several of their online colleagues in enthusiastically reporting on cool roofs, which “could help reduce global temperatures and offset the heat from as much as two years of global greenhouse gas emissions,” according to a new report from the Berkeley Lab. The report found that “increasing the reflectivity of roofs and pavement in cities with populations greater than 1 million would have a one-time cooling effect equivalent to reducing global CO2 emissions by 57 billion metric tons.” And more good news: “As part of an initiative to promote a transition to cooler surfaces, U.S. Energy Secretary Steven Chu directed all department offices to install cool roofs on any new buildings or when replacing old ones.”
Another widely-discussed piece today was about internet giant Google. As reported in Huffington Post, “Hot on the heels of its $38.8 billion investment in two wind farms in North Dakota, Google has just signed a 20-year contract with an Iowa wind farm that enables the search giant to purchase wind power at a set rate over the next two decades.” Treehugger goes on to praise the contract for not only taking a step toward the company’s stated goal of becoming carbon neutral, but also for providing critical funding for clean energy projects.
