2017’s breakdown of world energy sources shows that the globe, mainly dependent on grid power, uses a majority of non-renewables, while popular renewables such as solar PV and wind power are a small portion. Grid-connected buildings receive electricity from power plants, which mainly use natural resources such as coal and natural gas as energy to convert into electrical power. It is possible to simply eliminate electric power such as in Old Order Amish and Old Order Mennonite communities. Additional forms of energy include biomass, commonly in the form of wood, waste, and alcohol fuels and geothermal energy, which uses differences in the underground temperature to regular indoor air environments in buildings.
