Harvard team finds large-scale US wind power would cause warming that would take roughly a century to offset

Green Car Congress

All large-scale energy systems have environmental impacts, and the ability to compare the impacts of renewable energy sources is an important step in planning a future without coal or gas power. In the journal Joule , Harvard researchers report the most accurate modelling yet of how increasing wind power would affect climate.

EIA: US electricity generation from coal and natural gas both increased with summer heat

Green Car Congress

In August 2012, coal produced 39% of US electricity, up from a low of 32% in April 2012, when the natural gas share of generation equaled that of coal. The August coal share of generation is still notably lower than the 50% annual average over the 1990-2010 period. Data for 2011 and 2012 are preliminary.

EIA: US energy-related CO2 dropped 2.7% in 2015; of end-use sectors, only transportation increased

Green Car Congress

Specific circumstances, such as the very warm fourth quarter of 2015 and relatively low natural gas prices, put downward pressure on emissions as natural gas was substituted for coal in electricity generation. Coal’s share of total electricity generation in the power sector fell from 54% in 1990 to 34% in 2015. between 2014 and 2015.
