To ‘electrify everything’ the country is going to need a lot more electrical experts.

When we think about solving climate change, we often think about things that, in one way or another, plug into an electrical grid: Solar panels. Heat pumps. Efficient air conditioners. Wind turbines. Electric cars and electric car chargers. Induction stoves. Transmission lines.

Over the past several years, the mantra of energy experts has been that we need to electrify everything — and then switch electrical power generation over to clean sources of power like wind, solar, geothermal and nuclear. Doing so will rapidly decrease carbon emissions and help to stave off dangerous levels of warming.

But installing all of that electrical stuff — the solar panels, the heat pumps, the transmission lines — will require something that the United States doesn’t have: lots and lots of electricians.

According to the nonprofit group Rewiring America, which focuses on electrification, shifting the economy away from fossil fuels will require no fewer than 1 billion new electrical appliances, cars and other items in American households alone.
