For the first two decades after it is released into the atmosphere, methane is a more potent greenhouse gas than CO2. In assessing impacts of hydraulic fracturing, Bob Howarth (2000) says attention should be paid to the methane released when this drilling method is used to extract natural gas. In pursuing future energy sources, he stresses the need to move away from fossil fuels, including natural gas, and toward renewable fuels such as solar and wind power. "We should focus on reducing the use of fossil fuels, not finding more of them," he says.
