Since 2015, most of the new power<\/a> built in America has been clean. This year, 93% of new electricity capacity<\/a> is expected to come from solar, wind and batteries. That is not because of any president. It is because clean energy is the cheapest way to add electricity to the grid.<\/p>\n \nLeah Stokes\n<\/p>\n Anton Vonk Associate Professor of Environmental Politics at UC Santa Barbara<\/p>\n Leah C.

Today, 57%<\/a> of America’s power is generated from burning fossil fuels, compared to just 43% from clean sources. Even with solar and wind dominating new builds, our legacy system still uses dirty energy, which takes time to replace.<\/p>\n The first step is getting rid of coal, which already can’t compete with clean energy. Coal generates about one-sixth of our power, yet 99% of American coal plants are more expensive<\/a> to keep open than it would cost to replace them with new solar, wind, and storage. In Michigan, the Trump administration ordered an aging coal plant to stay open past its planned retirement. That single decision costs consumers $600,000<\/a> a day. On Sept. 11, a federal court rejected the order<\/a>.<\/p>\n You may like<\/p>\n \n The JH Campbell power plant in Michigan that Trump had ordered to be kept operating. <\/p>\n (Image credit: UCG via Getty Images)<\/p>\n Despite Trump’s attempts to revive a dying industry, the coal industry remains in deep decline \u2013 down 43%<\/a> since 2010. Coal cannot compete on cost or reliability. Without expensive government welfare, coal is on its way out.<\/p>\n Gas plants are responsible for much of the remaining electricity emissions. Solar, wind and batteries are increasingly cost-competitive<\/a> with gas. Even without subsidies, solar paired with batteries is now cheaper<\/a> to build and run than a new gas plant. And we know how to put up clean energy fast: the solar industry tripled<\/a> its annual build rate in just six years.<\/p>\n Skeptics raise two objections. First, rising electricity demand from AI, data centers and electrification means that we can’t generate enough power with clean energy alone, and therefore we need to keep gas on the grid. Second, Trump’s hostility \u2014 namely expiring tax credits and tariffs on solar panels and batteries \u2014 will stall the build-out.<\/p>\n Energy demand growth is real. Proposals for new gas plants to power data centers have surged<\/a>. But more than three-quarters of this gas plant pipeline is still early stage, and many projects have been delayed. Supply backlogs on gas turbines stretch toward the 2030s<\/a>. Meanwhile, new solar plants and batteries can go up in under two years<\/a>. This makes building such capacity the fastest, cheapest solution<\/a> to rising electricity consumption.<\/p>\n As for Trump: his administration won’t be around forever. And rising electricity prices have become a central issue<\/a> in this year’s midterms. Politicians promising affordability will turn to the cheapest way to power households: clean energy. And the market will keep the transition moving no matter who’s in the White House.<\/p>\n What to read next<\/p>\n \n Solar energy production, such as that produced by this solar panel array near Lancaster, California, now outpaces energy production from coal. <\/p>\n (Image credit: Mario Tama via Getty Images)<\/p>\n In the meantime, there is plenty we can do at the state and local level to speed things up. One strategy is removing barriers to plug-in solar. In Germany, more than a million households<\/a> have installed “balcony solar,” which are panels that plug into a wall outlet, bypassing permits or utility paperwork. Utah legalized<\/a> plug-in solar last year, and California’s legislature just approved<\/a> it too. Pair that with simple plug-in batteries, and ordinary people can generate and store their own clean energy at home.<\/p>\n We can also use electric machines to soak up power when it’s fossil-free. That happens in the middle of the day, when cheap solar floods the system. With the right controls, an electric water heater can also be a battery: heat the tank at noon, and tonight’s shower is stored sunshine. Heat pumps can pre-cool or pre-heat a home before evening the same way. Charge electric cars at work and your commute is solar-powered.<\/p>\n Exclusive to Live Science Pro<\/p>\n And none of this requires the federal government. States can make midday power cheap, or even free<\/a>, and pay households to shift their usage. Cities can write building codes that make flexible electric machines the default replacement. Do that at scale and we can serve growing demand with the grid we already have.<\/p>\n No single choice transforms the electricity system on its own. But the energy transition has always moved in waves: it dips, then surges back stronger. Millions of people pushing in the same direction is exactly how the next wave builds.<\/p>\n So is a clean grid realistic? Yes. The only real question is how fast we replace the old one. And that’s largely up to us.<\/p>\n Opinion<\/a> on Live Science gives you insight on the most important issues in science that affect you and the world around you today, written by experts and leading scientists in their field.<\/p>\n Help us improve Live Science Pro: We’re always trying to make our content better.
