U.S. Energy Secretary Steven Chu released this video recently, promoting energy efficiency and answering questions about how it can be used to cut costs at home. The Nobel Prize-winning physicist encourages people to help reduce carbon dioxide emissions through better insulation and other efficiency measures. Homes consume more than a fifth of the country’s total energy output.
“Just from my own personal experience, without doing a real deep makeover, if I can reduce my energy bills by a factor of two. … If everyone did that, that’s a 10 percent decrease in the amount of energy we consume and the amount of carbon dioxide we produce,” he says.
As I noted in an earlier post, some economists say it’s not that simple. Evidence shows what we do with the cash we save can fuel additional energy consumption.
