Electricity generation decreased 1.5 percent to 36,095,052 megawatthours in 2011 from 36,630,006 megawatthours in 2010. Most of Nebraska's electricity was generated by coal and nuclear power plants (71.94 percent and 19.21 percent, respectively). Plants using hydroelectric power generated 4.48 percent, wind generated 2.91 percent, natural gas generated 1.18 percent, other biomass generated 0.18 percent, and petroleum generated 0.10 percent.
In 2011, electricity generation by wind more than doubled from 2010, generation by hydroelectric power increased 23 percent, generation by petroleum increased 21 percent, generation by natural gas increased 14 percent, and generation by coal increased 11 percent. Electricity generation by nuclear power decreased 37 percent and generation by other biomass decreased 9 percent (offsetting the previous year's increase) from 2010.
There was an increase in electricity generation from other biomass from electric generators, electric utilities, between 1992–1998, because the Sheldon plant, operated by Nebraska Public Power District, was producing electricity from tire chips. There was no generation reported from this renewable energy source after 1998. The process was discontinued, because it was not considered cost–effective.
