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.

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.

The Climate Change and Your Health initiative is an effort by the Union of Concerned Scientists to highlight the health risks associated with global warming.

The highest tolerable wet-bulb temperature could be exceeded for the first time in human history in future climate scenarios.
