Xcel plans to double its renewable energy generation by 2030. It’ll cost consumers $8 billion to do it.
Big new solar and wind projects are planned to get Xcel Energy to 80% renewable generation in Colorado, but fossil fuels still will be needed to balance the system.
Wind power cut Xcel Energy’s carbon emissions last year. But is the utility moving fast enough to meet goals?

A disillusioned ExxonMobil engineer quit to take action on climate change. He found his net-zero place in Arvada.
After 16 years of working for the oil giant, Dar-Lon Chang said Exxon would not address climate change. So he quit the sector for good, and began a new low-carbon life.
Stay-at-home order changed the way Coloradans work. But is it improving emissions?
Teleworking may have reduced emissions from automobiles, but researchers say working from home increased household energy consumption by as much as 40%.
Dollars, not politics, are driving Colorado’s accelerated embrace of solar energy
Installing solar utility generation is now cheaper than wind or natural gas-fired plants, and far cheaper than new coal generation.
