The point is that it's impossible without huge suffering which people would rather not have.

It is absolutely not impossible to transition away from fossil fuels without suffering.

Fossil fuels aren't risk-free. Even if you don't care about CO2, fossil fuels are extremely inefficient in the long run because they're not renewable. Once you extract them and burn them, they're gone, forever. This IS NOT the case with renewable energy, which means that, as time goes on, renewables will be much cheaper than fossil fuels. Already, today, solar is much cheaper than petroleum per unit of energy.

In addition, every country on Earth can make use of renewables. Most countries cannot use fossil fuels directly, because they don't have them. This means they expose themselves to geopolitical risk. Exhibit A: this.

If the transition is done slowly, you end up saving money, not losing it. That means less suffering, not more.

I do not believe that is true.

Solar and EV technology are advancing rapidly, and with investment in grid infrastructure and incentives for generators to go renewable we could be along with Europe and China in reducing FF dependence for power. Instead the current administration is actively sabotaging the US position on renewable energy.
