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.

Unlike conventional vehicles, electric cars and trucks use a motor powered by batteries or a fuel cell.

They're a really good buy.

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

Hybrids use an internal combustion engine—and can be fueled like normal cars—but also have an electric motor and battery.

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

What materials and types of metals are used to make batteries for electric cars? How much do batteries cost? How long do they last?

How do self-driving cars work—and what do they mean for the future?

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.

Renewable energy—wind, solar, geothermal, hydroelectric, and biomass—provides substantial benefits for our climate, our health, and our economy.
