Using a new generation of combined cycle combustion turbines, these plants efficiently produce energy, creating a fraction of the pollution caused by other fossil fuels. Old natural gas technologies. A combustible mix of methane and hydrocarbons used in heating, lighting and other utility services. When coal or oil plants are converted to use natural gas, they burn cleaner but still produce harmful emissions. Oil, coal, natural gas or other petroleum-based resources are called fossil fuels because they are formed by the decayed remains of prehistoric plants and animals.
Large dams can change natural river flows, degrade water quality and block fish migration.
Smaller facilities can also have a high impact if they lack mitigation measures such as fish ladders that protect spawning or if they are located in sensitive areas. Nuclear plants create dangerous radioactive wastes that are difficult to dispose and last for centuries. Nuclear plants pose a risk of catastrophic disaster. Radionuclide emissions from power plants are believed to be linked to health problems in nearby communities. The pollution released into our environment by fossil fuel and nuclear plants have significantly negative impacts on health and quality of life.
