Xcel Energy serves 8 states in the west and mid-west of the USA. It is one of the largest US utilities.
Xcel Energy has cut carbon emissions 35 percent since 2005 and expects to surpass 50 percent by 2022, largely by retiring aging coal plants and replacing them with renewable sources.
The Minneapolis-based owner of Colorado’s largest utility appears ahead of schedule on its goal of reaching a 60 percent reduction in 2005 greenhouse gas emissions by 2030, and it is doing so without passing on cost increases to customers, according to the company’s Corporate Responsibility Report released this week.
Xcel has announced the retirement of 20 coal units, accounting for 40 percent of its coal-powered capacity, from 2005 to 2026, including several in Colorado. To fill the gap, the company has invested heavily in wind-powered sources, and to a lesser degree solar, while also promoting energy conservation.
Last year, about 40 percent of the electricity Xcel supplied came from carbon-free sources, and half of that amount from wind. Besides reducing its carbon output, the company said emissions of sulfur dioxide and nitrogen oxides were down by more than 70 percent. It also has cut its water consumption by 40 percent.

Last year, the utility reminded us that it originally believed that even a 5% penetration of renewables in the grid would lead to dangerous instability. Now it's heading for 60%.
