> I don’t see the logic? You use the surface area you have. Most people simply don't have a lot of ground to put solar on but they might have a roof. Also, you don't just need solar panels but also the wires to where the power is needed. On the roof of the building where you are using the power is just about as close as you can get with that. Otherwise it's a simple economic equation. If installing solar saves enough money such that you end up with a decent return on investment then making that investment is more optimal than not making that investment. That's why most of Australia is running on rooftop solar when the sun is shining. The US is a bit behind on that mostly because the US has a lot of rules stacked in favor of grid providers. Australia used to have that and eventually the grid providers lost that battle.
