Ormat Technologies is on an environmentally safe power trip, building geothermal, recovered energy, and solar power plants. Geothermal technology extracts hot water or steam that is vaporized and used to drive turbines. The fluid is then cooled and recycled back through the process, making it a clean and renewable energy source. Recovered energy utilizes heat produced in other industrial processes. The company, set up by Israel-based Ormat Industries, also sells power units for both types of plants, and sells fossil fuel-powered turbo-generators with a capacity of between 400W and 4,000W. Ormat operates power plants in Guatemala, Kenya, Nicaragua, and the US.
