Idea of Geothermal Filled Icon
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.
This is a Geothermal Filled icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,900 icons, all in the same style and quality.
