Information about the threats to the global environment from global warming and the loss of biological diversity.

Despite the remarkable human, environmental and economic benefits they have produced, 20th-century policy innovations are under attack in the 21st century.

Drivetrains are the collection of components that deliver power from a vehicle’s engine or motor to the vehicle’s wheels.

Fuel cell vehicles use hydrogen to produce electricity, generating less pollution than gas-powered cars and trucks.

Battery electric cars run exclusively on electricity—cutting air pollution and global warming pollution.

How does EV charging work? Types of charging options, charging time, costs and potential savings.

The evidence is overwhelming. Earth is warming fast, and the heat-trapping emissions we release into the atmosphere from burning fossil fuels is changing our climate.

Renewables face major obstacles. Some are inherent with all new technologies; others are the result of a skewed regulatory framework and marketplace.

Air pollution from coal-fired power plants is linked with asthma, cancer, heart and lung ailments, neurological problems, acid rain, global warming, and other severe environmental and public health impacts.

Coal is a main contributor to global warming, and has major negative effects on human health and the environment.

Lakes, rivers, streams, and drinking water supplies are all heavily impacted by coal mines and power plants.
