Utah group offers blueprint for alternative energy

A new study finds Utah could satisfy much of its energy demand with solar, wind and geothermal power.

The anti-nuclear group HEAL Utah commissioned an expert and a board of advisers to project Utah's energy demands for the next 40 years.

The study released Tuesday says the key to making the most of renewable power is having a way to store energy for times when it's most in demand.

It points to a Utah company, Magnum Gas Storage, that is looking at holding compressed air in salt caverns in Utah's west desert.

Magnum plans to dig salt caverns deep underground for natural gas storage, but the caverns also could hold compressed air, which can act like a battery for energy storage.
