"**The land efficiency of solar depends on what minerals we use**: when panels are made from silicon and placed on the ground rather than a roof, land use is marginally higher than coal. But if we use a cadmium panel, it needs less land than coal. "Of course, that’s not our only option with solar PV, which we can also put on roofs. Then, the only land use is for mining. **In that case, solar PV is almost as good as gas and is much better than coal**.
