The Northwest Power and Conservation Council says more electric cars on the roads will use more power in the future.
The Northwest Power and Conservation Council is increasing its previous estimates of how much power plug-in cars will need by 2030. The Council says high gas prices and better technology could drive up electric car sales.
That means drivers will need more power to plug in their vehicles.
On the low end of the scale, the Council estimates electric cars could use the same amount of power as roughly 80,000 homes every year. On the other hand, it may be about the same as 350,000 homes.
But the Council says more power plants will not need to be built.
Electric car sales have steadily increased during the first three months of this year.
