Last month, I blogged
about the Special Report on Renewable Energy Sources and Climate Change Mitigation
of the Intergovernmental Panel on Climate Change (IPCC), for which I was a coordinating lead author. In that report we found that by 2050, roughly 80 percent of global energy demand could be met by tapping renewable sources. The IPCC’s best-case prediction is contingent on a big caveat, however. It is that government policies must “play a crucial role in accelerating the deployment of Renewable Energy (RE) technologies.”
Fair enough, but which policies work best? Which can be replicated widely? Which sectors need more radical new approaches? Given the complexity of energy technologies, and markets, modes of power generation, transmission, distribution, consumption, metering and billing, and the multiplicity of policies—feed-in tariffs, subsidies, ‘feebates’, renewable portfolio standards, and so on— policy makers are often scrambling for guidance.
As author for the Policy and Deployment chapter of the IPCC report, as well as a member of the Summary for Policymakers’ team, I am pleased to suggest a useful source: a recent Discussion Paper No. 22
produced by my World Bank colleague Gabriela Elizondo Azuela, along with Luiz Augusto Barroso, Design and Performance of Policy Instruments to Promote the Development of Renewable Energy: Emerging Experience in Selected Developing Countries.
Elizondo and Barroso studied grid-connected RE policy options used in six countries—Brazil, India, Indonesia, Nicaragua, Sir Lanka and Turkey. They find that sound governance is an essential condition for the success of policy incentives that aim to accelerate the integration of renewable energy. “For example,” Elizondo says, “legal and regulatory frameworks for grid connection and integration have to be in place before RE policy is introduced.” In the IPCC report we called this the ‘enabling environment’.
