Policy Support for Renewable Energy Continues to Grow and Evolve

New Worldwatch Institute trend examines global support for renewable energy production

Washington, D.C.—Throughout much of the world, support policies for renewable energy technologies have increased dramatically over the last decade. Historically, policy design has evolved from supporting research and development in the 1970s and 1980s to today’s focus on technology deployment and market development. Starting in the mid-2000s, deployment-focused policies have been enacted at a rapid pace, growing from 48 countries with policies in place by mid-2005 to a total of 127 countries as of early 2013. Developing and emerging economies accounted for less than a third of all nations with policy support for renewable energy in 2005, but by 2013 they accounted for more than two-thirds, writes Worldwatch research associate Evan Musolino in the Institute’s latest Vital Signs Online trend. Musolino’s analysis is based extensively on data from REN21's Renewables 2013 Global Status Report, of which he is a co-author.

The majority of renewable energy support policies worldwide support electricity generation. Regulatory policies such as feed-in tariffs (FIT), net metering/billing, and renewable portfolio standards (RPS) or quotas have been developed to encourage the introduction of renewable energy technologies in the power sector. FITs remain the most widely adopted policy to support renewable energy. Altogether, 99 FIT policies are now in place worldwide at the national or state/provincial level. Municipal governments are also becoming more active in introducing FITs in cities.

Renewable portfolio standards or quotas for a specific required minimum share of renewable energy now exist in 76 countries, states, or provinces, up from 34 in 2004.

Policies to promote the uptake of renewable energies in the heating/cooling and transportation sectors, still lag behind policy activity in the electricity sector. Policies supporting renewable energy in the transportation sector through mandates and obligations are now in place in 51 countries at the national level. Biofuel blend mandates, a policy that requires a specific quantity of biofuels to be incorporated into transport fuel, are in place in 27 countries at the national level and in 27 states or provinces.

Tax incentives are being used to spur developments in the renewable energy sector in some 66 countries as of early 2013. Tax incentives can take many forms. Production tax credits, a main driver of the renewable energy sector in the United States, or investment tax credits allow for investments or stakes in renewable energy projects to be deducted from tax liabilities. Many countries have also enacted measures to reduce or exempt specific taxes on renewable energy technologies—such as value added tax, sales tax, or import duties—in an effort to decrease costs of project development.

As more policies have been enacted, regional diversity has greatly expanded. Of countries enacting policies by mid-2005, most (58 percent) were found in Europe and Central Asia, followed by East Asia and the Pacific (21 percent) and by Latin America and the Caribbean (LAC).By 2013, the share of Europe and Central Asia declined to slightly more than one third of the global total.

The economic diversity of countries enacting support policies for renewable energy has also greatly expanded. High-income economies accounted for 69 percent of all policy support by mid-2005, but by early 2013 this had declined to 30 percent. The other economic groups each increased their share by more than 10 percent.

“As the renewable energy sector continues to mature, policymakers face a host of new challenges,” said Evan Musolino, trend author. “While the pace of countries adopting new renewable energy support policies has slowed somewhat in recent years, the sector has experienced a flurry of activity centered on revising existing policy mechanisms. Policy changes have been driven by a variety of factors, both positive and negative.”

Rapidly changing market conditions for technologies such as solar photovoltaics, where module costs declined by 80 percent since 2008 and by 20 percent in 2012 alone, have dramatically reduced the level of support needed to make projects attractive to investors and feasible for project developers. Simultaneously, the global economic slowdown left many countries with continuously tight national budgets, which has threatened support for the renewable energy sector. The combination of factors has led to a number of cuts to existing incentive programs.

Additional challenges to the sector have come from the introduction of taxes or tariffs on renewable energy installations or components. Taxes on renewable energy were enacted in Bulgaria, Greece, and Spain in 2012. Trade disputes centered on the international trade of renewable energy components have also become prominent in recent years.

As countries begin to have higher shares of renewable electricity in their national energy mix, policymakers need to address new challenges. Policy priorities are shifting from a need to incentivize market takeoff to ensuring favorable market conditions for the expanding renewables market and seamless integration of renewable generation into grid networks. Despite substantially different degrees of market maturation, renewable energy technologies continue to get support from government policymakers worldwide. This support is expected to continue, and to evolve, as the sector develops.

Further highlights from the report:

  • As of early 2013, some 66 countries supported the renewable energy sector through their national tax codes.
  • In less than a decade, sub-Saharan Africa expanded from no renewable energy support policies to policies on the books in 25 countries, accounting for one fifth of all nations enacting these policies worldwide.
  • A significant increase of 17 countries was also recorded in the LAC region, while 12 countries enacted policies for the first time in the Middle East–North Africa (MENA) region.
