  • To Get Off Fossil fuels, America Is Going to Need a Lot More Electricians

    To cut greenhouse gas emissions on pace with the best available science, the United States must prepare for a monumental increase in electricity use. Burning fossil fuels to heat homes and get around isn’t compatible with keeping the planet at a livable temperature. Appliances that can be powered by clean electricity already exist to meet all of these needs. The problem is, most houses aren’t wired to handle the load from electric heating, cooking, and clothes dryers, along with solar panels and vehicle chargers. And a shortage of skilled labor could derail efforts to “electrify everything.”
