This report aims to highlight and raise awareness about the exposure and vulnerability of the energy sector to climate change. It identifies adaptation options available to each source of energy generation as well as for the distribution and end use of electrical energy. The report focuses on electric power generation, its transmission, and its distribution. A second publication, "Guidelines for Climate Proofing Investments in the Electric Power Sector", provides a systematic project-level approach for assessing climate risk and climate-proofing investments in the sector.
