Falling solar and wind prices have led to new power deals across the world despite investment in renewables falling

Renewable energy capacity around the world was boosted by a record amount in 2016 and delivered at a markedly lower cost, according to new global data – although the total financial investment in renewables actually fell.

The greater “bang-for-buck” resulted from plummeting prices for solar and wind power and led to new power deals in countries including Denmark, Egypt, India, Mexico and the United Arab Emirates all being priced well below fossil fuel or nuclear options.

Analysts warned that the US’s withdrawal from the Paris climate change agreement, announced last week by Donald Trump, risked the US being left behind in the fast-moving transition to a low-carbon economy. But they also warned that the green transition was still not happening fast enough to avoid the worst impacts of global warming, especially in the transport and heating sectors.

The new renewable energy capacity installed worldwide in 2016 was 161GW, a 10% rise on 2015 and a new record, according to REN21, a network of public and private sector groups covering 155 nations and 96% of the world’s population.

The new record capacity cost $242bn, a 23% reduction in investment compared to 2015, and renewables investment remained larger than for all fossil fuels. Subsidies for green energy, however, are still much lower than those for coal, oil and gas.

New solar power provided the biggest boost – half of all new capacity – followed by wind power at a third and hydropower at 15%. It is the first year that the new solar capacity added has been greater than any other electricity-producing technology.

“A global energy transition [is] well under way, with record new additions of installed renewable energy capacity, rapidly falling costs and the decoupling of economic growth and energy-related carbon dioxide emissions for the third year running,”

said Arthouros Zervos, chair of REN21.
