According to the International Energy Agency (IEA), the expansion of renewable energy will slow over the next five years unless policy uncertainty is diminished.
According to the Agency’s Medium Term Renewable Energy Market 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 stabilising after 2014, putting renewables at risk of falling short of the absolute generation levels needed to meet global climate change objectives.
Non-OECD markets, spurred by diversification needs in many countries and increasing air quality concerns in China, in particular, comprise approximately 70% of the growth. Renewables are seen as the largest new source of non-OECD generation through 2020, according to the IEA. However, 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.
IEA Executive Director Maria van der Hoeven commented: “Renewables are a necessary part of energy security. However, just when they are becoming a cost competitive option in n 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, the present and the future, as costs are falling over time. 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 noted that policy and market risks threaten to slow deployment momentum. For example, 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 (EU), 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 investment outlook. Through 2020, investment in new renewable power capacity is seen averaging over US$ 230 billion annually. This is lower than approximately US$ 250 billion invested in 2013. According to the IEA, the decline is due to expectations that both unit investment costs for some technologies will fall and that global capacity growth will slow. With decreasing costs, competitive opportunities are expanding for some renewables under some country-specific conditions and policy frameworks. 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 unsubsidised solar markets.
The roles of biofuels for transports and renewable heat are also increasing, though at slower rates than renewable electricity. Uncertainty over policy support for biofuels is rising in the EU and US, slowing expectations for production growth and threatening the development of the advanced biofuels industry at a time when the first commercial plants are just coming online.
