A GE Energy plant employee in Houston works to assemble a natural gas-powered aeroderivative turbine system. The completed unit will be part of a GE Energy line with models that have the capacity to generate 16 megawatts and 125 megawatts of electricity. The units can be turned on within 10 minutes. They can run on natural gas and other fuels, like ethanol. Photo: Zain Shauk/Houston Chronicle
