Wars over water will be fought very soon around the world.The undeniable fact is that "going green" is untenable without a massive change in energy expectations. Sometimes the sun doesn't shine. Sometimes the wind doesn't blow. Sometimes the water doesn't flow.
So if they don't want to incentivize fossil fuel usage, they can either build a whole lot of nuclear plants (no new ones since 1996), or we can simply accept that when we need energy the most, there will be less energy available than needed. There is no free lunch in this game.
That's not the worst of it either. The real pink elephant in the corner of the room is HCC or Human Carrying Capacity. This whirling blue ball is going to run out of capacity well before we expend all the fossil fuels. We're doubling the global population every 50-75 years (estimated). The western United States is going to exceed water availability well before the oil and natural gas wells run dry, and where do you think they're going to come for more water when that happens?
So someone born today will experience some level of strife just trying to stay alive within their natural lifespan. Think about that.
