How microgrids are bringing power to rural Kenya | GreenBiz
Microgrids are small electricity generation and distribution systems that operate independently of larger grids. Typically they rely on local sources of renewable energy, such as river flows, wind, biomass, or, most widely, the power of the sun. There are no official statistics on how many there are, or what their total power output is.
