IEA Increases Renewable Energy Forecast Amid Record Growth

The International Energy Agency (IEA) has announced it is significantly increasing its five-year growth forecast for renewables, thanks to strong policy support in key countries and sharp cost reductions. According to the IEA, renewables surpassed coal in 2015 to become the largest source of installed power capacity in the world.

The latest edition of the IEA’s Medium-Term Renewable Market Report now sees renewables growing 13% more between 2015 and 2021 than it did in last year’s forecast, due mostly to stronger policy backing in the U.S., China, India and Mexico. Over the forecast period, costs are expected to drop by a quarter in solar PV and 15% for onshore wind.

The IEA says last year marked a turning point for renewables. Led by wind and solar, renewables represented more than half of the new power capacity around the world, reaching a record 153 GW, 15% more than the previous year. Most of these gains were driven by record-level wind additions of 66 GW and solar PV additions of 49 GW.

According to the agency, about half-a-million solar panels were installed every day around the world last year. In China, which accounted for about half of the wind additions and 40% of all renewable capacity increases, two wind turbines were installed every hour in 2015.

“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,” said Dr Fatih Birol, the IEA’s executive director.

The IEA says there are many factors behind this remarkable achievement, including more competition, enhanced policy support in key markets and technology improvements. While climate change mitigation is a powerful driver for renewables, it is not the only one. In many countries, cutting deadly air pollution and diversifying energy supplies to improve energy security play an equally strong role in growing low-carbon energy sources, especially in emerging Asia, the agency notes.

Over the next five years, the IEA expects renewables to remain the fastest-growing source of electricity generation, with their share growing to 28% in 2021 from 23% in 2015.

Renewables are expected to cover more than 60% of the increase in world electricity generation over the medium term, rapidly closing the gap with coal. Generation from renewables is expected to exceed 7600 TWh by 2021 – equivalent to the total electricity generation of the U.S. and the European Union (EU) put together today.

However, although 2015 was an exceptional year, the IEA says there are still grounds for caution. Policy uncertainty persists in too many countries, slowing down the pace of investments. Rapid progress in variable renewables, such as wind and solar PV, is also exacerbating system integration issues in a number of markets, and the cost of financing remains a barrier in many developing countries. And finally, the IEA says, progress in renewable growth in the heat and transport sectors remains slow and needs significantly stronger policy efforts.

The IEA also sees a two-speed world for renewable electricity over the next five years. While Asia takes the lead in renewable growth, this only covers a portion of the region’s fast-paced rise in electricity demand. China alone is responsible for 40% of global renewable power growth, but that represents only half of the country’s electricity demand increase.

The agency says this is in sharp contrast with the EU, Japan and the U.S., where additional renewable generation will outpace electricity demand growth between 2015 and 2021.

The IEA report identifies a number of policy and market frameworks that would boost renewable capacity growth by almost 30% in the next five years, leading to an annual market of around 200 GW by 2020. This accelerated growth would put the world on a firmer path to meeting long-term climate goals, according to the agency.

“I am pleased to see that last year was one of records for renewables and that our projections for growth over the next five years are more optimistic,” said Birol. “However, even these higher expectations remain modest compared with the huge untapped potential of renewables. The IEA will be working with governments around the world to maximize the deployment of renewables in coming years.”
