@Hammerhead547 What rivers are left to dam without huge environmental or trade disruptions?

Nuclear plants take time to build, so the best short-term solution would be greater shift from coal to natural gas.

That is because it is heavily subsidized by the Chinese government. Bad news, they have a near monopoly. Goods news, the Chinese taxpayer has to pay a large part of every solar plant built.

I would take the timeline of the "point of no return" with grain of salt. Climatologist are very good at showing the effect of fossil fuels over time, but they have a terrible track record at making predictions. They are like the weatherman who can accurately tell you why it is snowing today, but is continuously wrong at predicting what day it will snow later in the week.

@GuitarDaddio China was dumping (using subsidizes to sell so the panels so cheap that it drives all competitors out of business).

The numbers look good, but there are a lot of assumptions made. Will the cost efficency stay constant as we build these massive installations outside the sunniest and windiest lands? For example, it make more economic sense to build a solar plant in Las Vegas, while a natural gas would be cheaper in area with more cloud cover like Seattle.

@joaquimbarbosa896 The only economical source for hydrogen is natural gas deposits which would kinda miss the point. There are very few places where you can store nuclear waste underground without it being at risk of being exposed by an earthquake or possibly sneaking into the water supply. For example, the Sierra Nevada is one of the only place that fits the criteria in the US.

@maximumd.3309 Yes, but demand for coal has likely peaked already, while demand for usable land and rare earth minerals needed for wind and solar farms will go up as we build new green energy installations. We can't assume the costs will stay this low if governments artificially increase demand with requirements for people to use renewable energy.

@Hammerhead547 The technology for economic carbon capture technology is decades away and it has the addition issue of where to store the extra carbon. The tech to build large scale batteries that would be required to make renewables work seems more promising based on recent advancements.

@Hammerhead547 I agree that A LOT of green subsidies seem to go towards left leaning lobbyist, but that doesn't mean there hasn't been technical advances in the field. On the other hand, there is been little to no advances in carbon capture technology in recent years.
