Answer:worst offender, a dirty energy source that produces less than half our electricity but nearly 80 percent of all power plant carbon emissions.
The good news is that coal is on the decline. Many old and inefficient coal plants are closing down and essentially no new coal plants are being built in the US, a trend that is driving the largest transformation of the US electricity system in half a century.
The energy choices we make during this pivotal moment will carry huge consequences for our health, our climate, and our economy for decades to come.
Right now we are moving toward a natural gas-dominated electricity system, but an over-reliance on natural gas has significant risks and is not a long-term solution to our energy needs. Like coal, it is a fossil fuel that generates substantial global warming emissions, and has other health, environmental, and economic risks.
There's a better, cleaner way to meet our energy needs. Renewable energy resources like wind and solar power generate electricity with little or no pollution and global warming emissions—and could reliably and affordably provide up to 40 percent of US electricity by 2030, and 80 percent by 2050.
To create a cleaner, safer, and healthier energy future, it's time to choose renewables first.
