KiloWatts for Humanity has been involved in rural electrification projects in
developing countries since 2009, and was formally incorporated as a
nonprofit organization in Washington state in January 2015.

We are an entirely volunteer-run organization which draws from our members’ varied backgrounds to address our common desire to end energy poverty. We partner with local and international nonprofit groups to provide renewable energy solutions in locations that have previously lacked access to development-enabling electricity.
