The Arizona Corporation Commission has a mandate in place requiring that at least 15 percent of the state's energy come from renewable sources by the year 2025. But despite its intention to wean the state off fossil fuels, the move has drawn vocal criticism from free-market advocates such as the Goldwater Institute, which claims the mandate will cost utility customers billions over the next 15 years.

Salt River Project announced Friday that it was considering raising electricity rates 8.8 percent, opening the next chapter in a long string of rate hikes to hit Arizona consumers over the past decade. But it also offered a glimpse of the future, where more energy will come from cleaner, renewable sources - but will come at a premium. If approved, the increase could go into effect in October.

If they could demonstrate there was a desire for renewables here, perhaps Arizona Public Service would sign a contract with an entrepreneur to start a solar, wind or biomass energy project in northern Arizona and create new jobs here, they reasoned. That didn't happen -- APS spent that money on renewable power elsewhere. But backers aren't dismayed and say they will continue the project this coming year.
