In the United States, 90 percent of electricity comes from conventional thermoelectric power plants – coal, nuclear, natural gas and oil – that require cooling.

Producing electricity from natural gas has implications for our water resources.

A primer on a national renewable electricity standard, including its mechanisms and the benefits that it can provide.

The press routinely cites climate contrarian think tanks without reporting their ties to the fossil fuel industry

The potential environmental impacts associated with solar power depend on the technology, which includes two broad categories: photovoltaic solar cells and concentrating solar thermal plants.

The environmental impacts of geothermal energy vary depending on the technology used to generate electricity and the type of cooling system utilized.

Wind power generates electricity without toxic pollution or global warming emissions, but it does have some environmental impacts that should be recognized and mitigated.

Hydroelectric power includes both massive hydroelectric dams and small run-of-the-river plants, both of which have associated environmental impacts.

Hydrokinetic energy includes wave and tidal power and encompasses an array of energy technologies, many of which are still in the experimental stages or in the early stages of deployment.

An overview of the environmental impacts of renewable energy sources such as wind, solar, geothermal, and biomass.

Facts about eight key facilities in the nuclear weapons complex, where weapons and their component parts are designed, assembled, tested, maintained and disposed of.

Nuclear power plants need a plentiful source of water nearby for cooling. But this proximity to rivers, lakes and oceans creates serious flooding risks that the NRC has been too slow to address.
