The Power Scorecard is a rating mechanism that assesses the environmental impact of different types of electric generation. The Power Scorecard makes it easy for you to plug into cleaner power for the future of the planet. The production of electricity is the single largest industrial contributor to air pollution today, and there are significant land and water impacts as well. Your choice is important because you can direct the dollars you spend on electricity service to cleaner, less polluting supplies.
Most electricity comes from coal, nuclear reactors, and large hydropower facilities.
Electricity and the environment Different ways of producing electricity have vastly different impacts on our environment. The Power Scorecard ratings appearing on this website may be based on assumptions made by the sponsoring organizations as to the composition, fuel sources, technologies, and associated environmental attributes of particular products where such information is unknown to or has not been provided by the supplier, and where such information is not publicly available. However, every effort is made to validate the information used in rating products with supplier.
