There was a record amount of new renewable energy installations globally in 2015, with 500,000 solar panels installed every day.

According to the International Energy Agency (IEA), total clean power capacity increased by 153 gigawatts, overtaking coal for the first time.

"We are witnessing a transformation of global power markets led by renewables and, as is the case with other fields, the center of gravity for renewable growth is moving to emerging markets," Dr. Fatih Birol, the IEA's executive director, said.

The agency also raised its five-year forecast for renewable energy by 13 percent and now expects renewables to be 42 percent of global energy capacity by 2021.
