A gradual shift away from coal-generated electricity in the U.S. has resulted in a drop in power-plant COpollution. April COpower-plant emissions were nearly back to 1988 levels. Between April 1988 and April 2015 coal use for power generation decreased 17 percent, while the use of renewable sources, like solar, wind, and hydro, increased by more than 100 percent. Burning coal is considered to be the dirtiest method, in terms of CO2 emissions, currently being used on a large scale to generate electricity.

For an island of only about 14,000 people Kodiak Alaska uses a lot of electricity. So it’s impressive that 99.7% its annual electricity needs are met by pollution free sources. And when the Kodiak Electric Association (KEA) switched to full renewables use, it eliminated $7 million a year in fuel costs for diesel powered generators.

Wind supplies over 100% of Denmark’s electricity demand

wind farmDuring the evening of Thursday July 9, electricity generated by wind supplied 116% of Denmark’s electricity demand.  By 3:00 am the next morning the percentage had risen to 140. A surge in windfarm installations means Denmark could be producing half of its electricity from renewable sources well before a target date of 2020, according to Kees van der Leun, the chief commercial officer of the Ecofys energy consultancy.  The original full version of this story can be read in The Guardian.
