Geothermal Icon in Android Style

This Geothermal icon has Android KitKat style. If you use the icons for Android apps, we recommend using our latest Material Icons icon pack (please check our sidebar on the right). Otherwise, it's a solid icon pack that looks good in small resolutions, either on the web or in print. It's characterized by thick lines, smooth corners, and is optimized for 24x24 pixels.
The geothermal icon is represented with a building, but one part of the building will have higher top where smoke will come out of. The other part of the icon is there will be arrows coming from the bottom of the building or the ground and into the building.

Idea of Geothermal Icon by Eric Brissette

We've received the idea on January 29, 2013 and created the icons on April 04, 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.
