In its 2015 “Global Status Report”, REN21, the global renewable energy policy network, has summarised the increase in renewable energy capacity in the 10 years from 2004 to 2014.
In 2004, global renewable power capacity (excluding hydro) was 85 gigawatts. In 2014, it reached 657 gigawatts.
Solar PV capacity increased from just 2.6 gigawatts to 177 gigawatts, while concentrating solar thermal capacity increased from 0.4 gigawatts to 4.4 gigawatts.
Wind power capacity increased from 48 gigawatts to 370 gigawatts. Bio-power capacity increased from less than 36 gigawatts to 93 gigawatts. And geothermal capacity increased from 8.9 to 12.8 gigawatts.
At the end of 2014, fossil fuels still accounted for 77.2% of global energy production. Hydro was 16.6% of the total with wind being 3.1% and bio-power 1.8%. Although 40 gigawatts of solar capacity was added in 2014, it is still less than 1% of the total.
China had the most renewable power generation capacity; leading the world in wind and hydro capacity. The United States led in geothermal and bio-power with Germany having the most solar capacity.
The report estimates that, at the end of 2014, there were 7,647,000 jobs directly or indirectly in renewable energy.
