Infographic: Gas Flaring Worldwide

The problem of gas flaring Gas flaring, or the venting of natural gas, is a common process associated with oil extraction and other industrial activities. In the United States, gas flaring has grown right along with the boom in “tight oil” plays such as North Dakota’s Bakken field. Of course, flaring gas is not limited to the U.S. but is a…

Renewable sources provide nearly half of all new generating capacity in 2014

Renewable Energy Beats Natural Gas for New Capacity in 2014

It was a close race throughout the year, but in the end new generating capacity from renewable sources beat out new natural gas capacity by 1.16 percent in 2014. Of the 49.81 percent of new capacity from renewable energy, more than one-quarter, or 26.52 percent, came from wind energy while solar power provided another 20.40 percent of the total. Other…

An Uptick in US Greenhouse Gas Emissions as Utilities Use More Coal

Natural gas prices coming off their lows prompted utilities to burn more coal, which in turn led to the first increase in U.S. carbon emissions in three years. Longer term, US greenhouse gas emissions are 10% or more below 2005 levels, a downward trend the U.S. Energy Information Administration forecasts will continue.

Phase-Out of Greenhouse Gas Emissions by 2050 Technically, Economically Feasible

Completely phasing out net greenhouse gas (GHG) emissions by 2050 is not only technically feasible, but could be done at very manageable cost, according to a comprehensive study by Ecofys for the Global Call for Climate Action. “It is technically and economically feasible to reduce emissions to zero for roughly 90% of current sources of GHG emissions with technological options…
