Brazil relies heavily on its abundant hydropower resources to meet electricity demand, which is rising by about 5% a year. These resources have helped Brazil hook up more than 2.4 million rural homes since 2003, in addition to delivering electricity to its big cities. But hydropower is vulnerable to drought too, and the Brazilian Amazon—home to most of the country’s hydropower potential—has had two devastating droughts since 2005.
That’s just one example of the exposure of the energy sector to climate impacts. Up to now, most of the focus for the discussion of the energy-climate nexus has been on the impact of fossil-fuel energy use on climate change, the need to mitigate it, and the shift to renewable energy sources. This week, two World Bank colleagues of mine have just launched a new study that looks at the issue from the opposite side of the equation: climate impact on energy systems.
The study is entitled Climate Impacts on Energy Systems, Key Issues for Energy Sector Adaptation, by Jane Ebinger and Walter Vergara. It provides a framework for further analysis of vulnerability indicators for climate impacts on hydropower, wind, solar, wave and tidal energy. It also offers analytical tools that experts and policymakers can use to construct vulnerability and impact metrics for their energy sectors, along with a review of emerging adaptation practices.
