It's a logo for hydroelectric power that shows a gear that looks like a sun with an electric bolt in the center. It is depicted over two horizontal lines that are waves.
This icon is a part of a collection of Hydroelectric flat icons produced by Icons8. Icons follow the guidelines of iOS, Windows, and Android and are designed by a single designer, guaranteeing the consistent quality.
Idea of Hydroelectric Icon by Eric Brissette
We've received the idea on January 30, 2013 and created the icons on April 5, 2013
Icons for green/renewable energy sources. The two I'm looking for are a Wind Turbine and Solar Panels. Other possible ideas are Hydroelectric, Geothermal, and Biomass, but those icons may be more difficult to portray with a simple icon.
