Yeah, but energy is energy, from whatever source. (I admit I am old school on physics / energy.)
If it is emitting it, like the observer says, where is it going?

Unless we are talking about Wind or Solar energy. Then ‘energy’ is money, corruption, bribes, destruction of the planet.
True based on our current knowledge of physics but would you agree if some alien species has figured out how to travel thru space to earth they likely have an understanding of physics far beyond anything humans have ever conceived, that’s all I’m saying
