To those who are responding to my own posts, just to say that I wasn't referring to CO2 or pollution or any type of emissions.
Simply producing energy, whether renewable, nuclear, or via cardon-burning, has a massive footprint on the environment.
We're mining millions of tones of iron ore, pouring millions of tones of concrete, and we're reshaping massive areas and destroying wildlife.
Of course we need to produce energy, but it's costing us the planet. We're causing disruption to our ecological systems and killing the local fauna and flora on a massive scale.
Encouraging people to consume more energy just because someone invented a 'green' engine is lunacy, in my opinion.
