Energy policy and global warming

Fig.1 World electric power consumption in 2021 was 3030 GW. This may soon double, including many coal plants in the developing world.

Fig.2 Electric power generation is only a third of our CO2 problem. A zero-carbon future should include process heat for industry and fuels for transportation.

Fig.3 Success in reducing CO2 requires abundant, clean, non-intermittent power.

Fig.4 Wind and solar alone are not enough.

Fig.5 Wind and solar as the only solution will require unrealistic commitments of land and resources and a new storage technology far less expensive than today's batteries.

Fig.6 One GW of nuclear power can be small, safe, and clean. Recycling fuel and used reactors can be done at a central secure location.

Fig.7 Time is short, and build rate is critical to meeting our goals.

Fig.8 Few countries are now on track.

Fig.9 Decarbonizing industry will require vast amounts of process heat, either directly from a nuclear reactor, or using hydrogen as an intermediary.

Climate scientists tell us that our consumption of fossil fuels is raising atmospheric CO2 levels, causing rapid global warming, and risking catastrophic climate change. Most people now accept these conclusions, but there is still debate over whether the replacement for fossil fuels should include nuclear power. Many believe that nuclear power cannot be made safe and clean. Others believe that an energy policy that does not include nuclear is unrealistic. This article is a brief review of the options for decarbonizing our world.

The Magnitude of the Problem

The Problems with Wind and Solar Alone

• use of land and mineral resources
• need for 100% fossil fuel backup
