"It's a simple comparison, yes." But Rose will leave it at that, because really, simple is better. Especially when she doesn't know all the technicalities herself. Someone else can do something more in depth with him regarding that.

"It depends on the time and the resources. I'm not sure what here does, but they still mine coal so it must be used in some way. Coal can be burned and the destruction of it in turn creates energy that can be used. So they burn it in a power plant and it travels via wiring to those fixed points to be used. Other sources in wind, where they wind moves turbines and that movement creates energy, or water which does much the same. There can also be solar, when panels absorb the heat and energy from the sun which is converted into electricity."

She pauses, frowning slightly. "I'm sorry I'm not completely sure on the details, I was never particularly focused in science classes."
