The scale at which humans draw energy from the core is negligible compared to the amount. Think about it, earth has been cooling down through radiating from the surface for billions of years. Given the ratio of the geothermal station and the surface area of earth, I don't think there is anything to worry about.
As for solar, the incoming energy would have been mostly converted to heat. When we use the electricity produced, we convert it back to heat again. If the entire state of AZ were covered with solar panels, and all the energy spent in NY, there would be some localized changes but not much in the global scale. For the foreseeable future, we are not even close to covering up just 1% of the land area of AZ.
- infinite8s 9y agoEarth's radiation scales as a cube of the radius. Our energy usage is growing exponentially. You can apply big-O analysis to this problem ;)
- badosu 9y ago> Our energy usage is growing exponentially. Well, with efficiency gains in the latest years energy consumption (not only electricity) actually is constant or decreasing in developed countries. Add to that decreasing population fertility and if you expect that developing countries are going to follow the same trends after a certain threshold then that's not a good assumption long-term.
