Basin Electric Power Cooperative said its sources of fuel to generate power have changed quite a bit since the year 2000.
Basin senior legislative representative Dale Niezwaag said in 2000, 85 percent of electricity generated by the co-op came from coal, with 10 percent hydropower, and the rest from oil, diesel and wind.
And by the end of this year...
"We'll have about 24 percent of our portfolio as renewable," Niezwaag said. "About 23 percent of that is wind."
The rest of that mix: 46 percent coal and 19 percent natural gas.
