Axios - A trio of factors have helped keep national average power prices in check over the last 15 years, but don't expect this to last much longer.  Even though electricity prices rose in dollar terms almost everywhere since 2010, inflation rose faster.

• That means power became cheaper in real terms in much of the country.

Three factors have been driving this trend, per Gramlich.

• Flat power demand, which is now rising and hiking prices.
• Cheap natural gas, whose costs are forecast to rise by next year.
• Falling renewable costs.

Not much unites the states when it comes to electricity, considering how arcane and regionally different electricity markets are.

• "Some states like Nevada, Texas, and Iowa seem to be experiencing the consumer savings that come with large-scale renewable energy deployment," Gramlich said when Axios shared the map for his insight.
• "Other states like California seem to be experiencing the effects of tens of billions of dollars of wildfire-related expenditures that get included in utility bills."
