Global renewable capacity grew by record levels in 2016, at a 23% lower cost than the previous year.
That’s according to new research published by UN Environment, the Frankfurt School-UNEP Collaborating Centre and Bloomberg New Energy Finance.
The report shows 138.5GW of new wind, solar, biomass, geothermal, small hydro and marine power was installed, an 8% increase from the 127.5GW of new capacity built the year before.
The total investment was $241.6 billion (£194.90bn), the lowest annual figure since 2013.
The research shows this was primarily a result of falling costs – the average cost per megawatt for solar photovoltaics and wind dropped by more than 10%.
Investment in new renewable capacity was roughly double the spending on fossil fuel generation, making up around 55% of all new power, the highest proportion ever recorded.
The share of electricity coming from renewables rose from 10.3% to 11.3%, cutting 1.7 billion tonnes of Carbon Dioxide.
Erik Solheim, Executive Director of UN Environment, said: “Ever cheaper cleantech provides a real opportunity for investors to get more for less.
“This is exactly the kind of situation, where the needs of profit and people meet, that will drive the shift to a better world for all.”
