Between 2007 and 2015, solar and wind power capacity increased in the US from just 10GW to around 100GW.
A new study published in the Nature Energy journal claims that this ten-fold growth, coupled with changes in fossil fuel price and regulation, had the knock-on effect of preventing up premature deaths thanks to a significant reduction in emissions and subsequent air quality improvement.
The US Department of Energy-funded research found that carbon dioxide emissions fell by 20% in the period, while sulphur oxide and nitrogen oxide plummeted by 72% and 50%, respectively. Tiny particulate matter decreased by 46%.________________________
Researchers estimated that “cumulative wind and solar air-quality benefits” in the 2007-2015 period totalled between $29 billion and $112 billion.
