A good explanation, totally lost on Ding.I'm quivering with anticipation.
Explain how the energy in the Earth system is reduced.
Potential energy is like when an overhead crane lifts something.
If the solar energy is used to power a crane, the Earth is cooler than if the sunlight hit the surface?
Kinetic energy would be like an electric motor powering a water pump.
If the solar energy is used to pump water, the Earth is cooler than if the sunlight hit the surface?
Do we have to pump the water uphill or to the top of a building to cool the Earth?
What if we pump it up and let it move back down? Still cools the planet?
None of which heat the surface of the planet.
Does the crane warm up at all when it works? What about the pump?
How did the electricity get to the crane and the pump? Any heat generated?
How efficient are the solar panels? Any heat involved there?
So many issues. Maybe you can help me understand?
