People and businesses are using more electricity than before.
New data centers for artificial intelligence, more electric vehicles, and electric stoves all need extra power.
The United States government thinks demand will rise about 2% this year and next year.
Home electric bills are going up fast, about twice as fast as other prices.
One reason is that natural gas, which many power plants burn to make electricity, now costs more.
The high bills were an important topic in recent elections in New Jersey and Virginia.
Electric companies say they must spend over one trillion dollars in five years to build new plants and make the electric grid stronger.
They plan to get the money from customers, but some people ask if large data centers should pay more of the cost.
If data centers get special low prices, home customers may end up paying extra.
Power is most expensive on very hot days when air conditioning is on everywhere.
Experts say data centers could move to backup power or shift work to cooler places for about 50 hours each year to save money.
People with electric vehicles can also save by charging at night when demand is low.
The country has handled big jumps in electricity use before, such as in the 1960s when many homes first got air conditioning.
