Welcome to ECPA

Leaders of the Western Hemisphere recognize that clean energy is fundamental to the Western Hemisphere’s sustainable development and the prosperity of our citizens, and they are committed to expanding cooperation to address the intertwined challenges of energy security and climate change. To strengthen Inter-American collaboration on these issues, the government of the United States invited all countries of the Western Hemisphere to join in an Energy and Climate Partnership of the Americas (ECPA). ECPA is comprised of initiatives that focus on renewable energy, energy efficiency, energy poverty, infrastructure, cleaner and more efficient use of fossil fuels, sustainable forests and land use, and climate change adaptation.

Finding New Synergies between Water and Energy

May 11, 2018

Consider these two seemingly unrelated problems: Solar and wind energy are intermittent, and fresh water is often in short supply. An integrated system that combines existing technologies—and that runs entirely on renewable energy—could solve both those problems at the same time, an engineer from the Massachusetts Institute of Technology maintains. And, he says, several sites in the Americas have the perfect topography for putting such a system to the test. The key is to have mountains next to the sea. All the technology needed for this combination water-and-power system already exists, says Alexander Slocum, the Walter M. May and A. Hazel May Professor of Mechanical Engineering at the Massachusetts Institute of Technology (MIT) and lead author of a paper on the subject published in the journal Sustainable...Read More
