>Energy can be neither made, nor destroyed, it simply changes forms.

You need to understand the concept of entropy, which is the state of disorder in a system. Any time you convert energy, entropy increases, which is why there's never a free lunch. Jeremy Rifkin wrote a book titled "Entropy: A New World View" back in 1980, which was highly prescient of the situation we are now in: consumption of resources continuing to accelerate worldwide with potentially cataclysmic consequences.

But there is very little penalty today for wasting energy. People had a fit over the elimination of 100 watt incandescent light bulbs; imagine the noise they would raise if they were expected to cut their individual energy consumption in half.
