IEA: Uncertainty threatens to slow renewable energy momentum

Share

In a new report, the International Energy Agency (IEA) says renewable energy around the globe is facing growing risks to deployment over the medium term despite being a cost-competitive option in an increasing number of cases.

Presented in Paris on Thursday, the Medium-Term Renewable Energy Market Report details the IEA’s findings showing how the expansion of renewable energy will slow over the next five years unless policy uncertainty is diminished.

According to the report, power generation from renewable sources such as wind, solar and hydro grew strongly in 2013, reaching almost 22% of global generation, and was on par with electricity from gas, whose generation remained relatively stable. Global renewable generation is seen rising by 45% and making up nearly 26% of global electricity generation by 2020. Yet annual growth in new renewable power is seen slowing and stabilizing after 2014, putting renewables at risk of falling short of the absolute generation levels needed to meet global climate change objectives.

Markets outside the Organization for Economic Co-operation and Development (OECD), spurred by diversification needs in many countries and increasing air quality concerns in China, in particular, comprise almost 70% of the growth, according to the report. Renewables are seen as the largest new source of non-OECD generation through 2020. Yet the IEA says they meet only 35% of fast-growing electricity needs there, illustrating the still-large role of fossil fuels and the potential for further renewable growth.

Renewables account for 80% of new power generation in the OECD, but with more limited upside due to sluggish demand and growing policy risks in key markets.

"Renewables are a necessary part of energy security," said IEA Executive Director Maria van der Hoeven. "However, just when they are becoming a cost-competitive option in an increasing number of cases, policy and regulatory uncertainty is rising in some key markets. This stems from concerns about the costs of deploying renewables.

"Governments must distinguish more clearly between the past, present and future, as costs are falling over time," she added. "Many renewables no longer need high incentive levels. Rather, given their capital-intensive nature, renewables require a market context that assures a reasonable and predictable return for investors. This calls for a serious reflection on market design needed to achieve a more sustainable world energy mix."

The report notes that policy and market risks threaten to slow deployment momentum. In many non-OECD markets, including China, constraints include non-economic barriers, an absence of needed grid integration measures, and the cost and availability of financing. In the European Union, uncertainties remain over the precise nature of the post-2020 renewable policy framework and the build-out of a pan-European grid to facilitate the integration of variable renewables.

For the first time, the annual report provides a renewable power investment outlook. Through 2020, investment in new renewable power capacity is seen averaging over $230 billion annually. That is lower than the around $250 billion invested in 2013. The decline is due to expectations that both unit investment costs for some technologies will fall and that global capacity growth will slow, according to the report.

"With decreasing costs, competitive opportunities are expanding for some renewables under some country-specific conditions and policy frameworks," the report points out. "For example, in Brazil, with good resources and financing conditions, onshore wind has continued to outbid new-build natural gas plants in auctions. In northern Chile, high wholesale electricity prices and high irradiation levels have opened a new unsubsidized solar market."

The study is part of a series of annual reports the IEA devotes to each of the main primary energy sources: oil, gas, coal, renewable energy and – as of last year – energy efficiency.
