Because nuclear power plants produce a lot of electricity in a small space, they require far less land for siting and operation than all other energy sources. To build the equivalent of a 1,000-megawatt nuclear plant, a solar park would have to be larger than 35,000 acres, and a wind farm would have to be 150,000 acres or larger. By contrast, the Millstone Units 2 and 3 nuclear power plants in Connecticut have an installed capacity of over 1,900 megawatts of power on a 500-acre site.
