Vermont’s electricity generation became 100% from green power sources in late 2014, when the state’s only nuclear power plant permanently closed. Additionally, according to USEIA data five other states are encouragingly not far behind. As of June 2015, renewable sources power 60% or more of those states’ electricity production. Continue reading Vermont electricity is 100% renewable & Green Power exceeds 60% in 6 U.S. states

Five of the 25-largest oil and gas companies in the world have committed to work to reduce methane emissions and share the lessons that they learn while doing so. They, along with the fifth largest U.S. natural gas producer and one of largest suppliers of liquefied natural gas (LNG) imported by the U.S., are members of the United Nation’s Climate & Clean Air Coalition Oil & Gas Methane Partnership (CCAP OGMP).

More than 1,300 large U.S. electricity users, including 78 Fortune 500 companies, belong to the U.S. Environmental Protection Agency (EPA) Green Power Partnership. Partners pledge to use, at a minimum, green power for a specified percentage of their electricity use. For members using the most electricity, program requirements mean that at least 3 million kWh of the electricity that they use each year be green power. Continue reading Top 5 U.S. green-power users avoid CO2 = 785,000 households

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.
