Now utilities are relying more on natural gas to generate electricity as discoveries around the world boost the fuel\'s supplies. The big, expanding economies of China and India are building more nuclear and hydro-electric power plants. Renewable energy sources such as wind and solar, while still a small fraction of the global energy mix, are growing fast as they get cheaper. And a greater emphasis on efficiency is tempering global growth in electricity demand.
