Lakota Solar Enterprises (LSE) is a Native American-owned renewable energy company on the Pine Ridge Reservation that manufactures and installs solar heaters. Through the Red Cloud Renewable Energy Center (RCREC), LSE trains others to do the same in their tribal communities. The heaters, which cost about $2,000 installed, provide supplemental heat and significant savings for low-income families. RCREC, with support from the non-profit Trees, Water & People, has provided hands-on training to more than 150 Native Americans from all over the US, and more than 1,400 of the solar heaters have been installed.
