Here I quote from "
Light, Water, Hydrogen: The Solar Generation of Hydrogen by Water Photoelectrolysis"
"Both fossil and fissile energy sources are finite and, on our current projected course, will soon be exhausted. Considering the scale of the problem, i.e. a world population of 10 billion by 2050, energy conservation can only modestly delay the day societies find themselves, as they say, between a rock and a hard place. The survival of modern society, as we know it, faces collapse unless alternate routes for energy production are established."
And, this textbook was apparently published in 2007. That was even too late. 5 years later and people still think wasting their time conserving or recycling for any other reason other than to save money... money that is a worthless ponzi scheme btw...
It makes me sad to think of all the wasted energy, especially since they all seem to have the best intentions and are simply misled by old ideas.
