US renewable energy growth helped prevent thousands of deaths

US emissions fell dramatically between 2007 and 2015, thanks to increased renewable energy use and tighter rules.
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%.

Europe's wind capacity grows but concerns persist

The first half of 2017 saw 6.1 gigawatts of extra wind power capacity installed in Europe. But a lack of long-term political commitment has hit investment and market concentration remains problematic.

Researchers estimated that “cumulative wind and solar air-quality benefits” in the 2007-2015 period totalled between $29 billion and $112 billion.
