Agree, in general. I've always floated the following ideas as how I think this can shake out:
- Starting now -> future: Continue to build out solar, wind, and hydro power where it's viable.
- Near term: Replace coal plants with natural gas, which have half the carbon output. Start building modern* nuclear fission plants.
- Medium term: At a certain point, retire the natural gas plants as enough nuclear comes on-line. Sooner the better here, as the goal is carbon reduction.
- Long term: Nuclear fusion plants (probably at least 20-30 years away from any practical, commercial viability).
Renewables like solar, wind, and hydro power are
great. But the first two need a backup for when generation isn't optimal (dark/cloudy/windless days). Thus the natural gas -> fission -> fusion suggestions. Hydro is also great, but only works in specific locations.
* Yes, there is such a thing. Modern fission plants
can be built safely. Problems like Chernobyl or Fukushima occur because of ancient, shoddy design (Chernobyl) or really stupid geographic placement (Fukushima). The waste problem can be solved if we get politics and NIMBY stuff out of the equation. There are also fast breeder reactors that can recycle fuel. Getting carbon out of the atmosphere is a
much more pressing issue.
