100% Wind Water Solar Not "All of the Above"

Why We Must Focus on Clean, Renewable Energy and Storage, Not “All of the Above,” For Solving Global Climate, Air Pollution, and Energy Security Problems

A slide deck from Mark Z Jacobson presented at the American Geophysical Union meeting on December 11, 2023

Conclusion

Carbon capture, direct air capture, blue hydrogen, non-hydrogen electro-fuels, and bioenergy even when powered by wind-water-solar (WWS), all increase CO2, air pollution, and social cost and either fossil mining and infrastructure or land use versus using the same WWS to replace a CO2 source CCS [Carbon Capture and Storage], DAC [Direct Air Capture] always increase CO2 and new nuclear increases cost, time-to-operation, emissions, and catastrophic risk versus new wind/solar.

However, a Wind, Water, Solar (WWS) Solution is practical and we can "electrify or provide direct heat for all sectors and provide [that] electricity and heat with 100% WWS. " The book “No Miracles Needed” explains how to transition to 100% WWS. https://web.stanford.edu/group/efmh/jacobson/WWSNoMN/NoMiracles.html

I believe Mark Z Jacobson is doing essential work.
