The Corbetti Geothermal Project is expected to consume 4 billion dollars and will generate 1,000 MW of electricity.Geothermal power plants are built by drilling deep into the ground, not unlike drilling for oil or gas. But instead of burning fossil fuels, geothermal plants capture steam, converting heat from the earth into power. They emit a fraction of the heat-trapping greenhouse gases that conventional coal plants emit.The project falls under the umbrella of Obama’s Power Africa initiative, which Obama launched in 2013 to try to double access to electricity in sub-Saharan Africa. While in Africa, Obama said the U.S. would continue supporting Ethiopia’s green energy endeavor.
