Former U.S. President Bill Clinton is talking up the potential of renewable energy to shield developing countries from the effects of climate change.

Clinton visited Central America’s biggest wind farm Tuesday. The electricity project in western Panama is scheduled to open next year with the capacity to produce about 6 percent to 8 percent of Panama’s energy needs.

The Clinton Global Initiative has provided support to the project, which was started in 2012 by a private equity firm with energy investments in Latin America.

Clinton’s visit to Panama is part of a Latin American tour that also includes stops in Peru and El Salvador.
