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.”

The long view
Helping Strengthen America’s Critical Infrastructure
Everyday life depends on a robust infrastructure network that provides access to running water, communications technology and electricity, among other basic necessities. The experts who keep our national infrastructure secure and resilient also need a strong network to share their knowledge and train the next generation of professionals capable of solving complex infrastructure challenges.
AI and the Future of the U.S. Electric Grid
Despite its age, the U.S. electric grid remains one of the great workhorses of modern life. Whether it can maintain that performance over the next few years may determine how well the U.S. competes in an AI-driven world.
Using Liquid Air for Grid-Scale Energy Storage
New research finds liquid air energy storage could be the lowest-cost option for ensuring a continuous power supply on a future grid dominated by carbon-free but intermittent sources of electricity.
Enhanced Geothermal Systems: A Promising Source of Round-the-Clock Energy
With its capacity to provide 24/7 power, many are warming up to the prospect of geothermal energy. Scientists are currently working to advance human-made reservoirs in Earth’s deep subsurface to stimulate the activity that exists within natural geothermal systems.
Experts Discuss Geothermal Potential
Geothermal energy harnesses the heat from within Earth—the term comes from the Greek words geo (earth) and therme (heat). It is an energy source that has the potential to power all our energy needs for billions of years.
