A Worldwide Plan to Eliminate Global Warming, Air Pollution, and Energy Instability With Wind, Water, and Sunlight (WWS)
Abstract
Global warming, air pollution mortality, and energy insecurity are three of the most significant problems facing the world today. This talk discusses a plan to solve the problems by powering 100% of the world's energy for all purposes, including electricity, transportation, industrial processes, and heating/cooling, with wind, water, and sunlight (WWS) within the next 20-40 years. It reviews and ranks major proposed energy solutions to global warming, air pollution mortality, and energy insecurity while considering other impacts of the proposed solutions, such as on water supply, land use, resource availability, reliability, wildlife, and catastrophic risk. It then evaluates a scenario for powering the world on the energy options determined to be the best while also considering materials, transmission infrastructure, costs, and politics. The study concludes that powering the world with WWS electric power technologies and a conversion from combustion to electricity and electrolytically-produced hydrogen is the cleanest and safest method of solving these problems. Due to the efficiency of electricity, such a conversion reduces world power demand by 30%. Methods of ensuring reliability of WWS electric power are available and will be demonstrated. We also conclude that neither liquid biofuels for transportation (including ethanol or biodiesel from any source), solid biofuels for home heating and cooking, biomass for electricity, conventional or fracked natural gas for electricity or transportation, nuclear power, nor coal with carbon capture (clean coal) are nearly so clean or safe as WWS technologies so are not recommended, either as bridge technologies or in the long term. Our plan calls for all new energy to be supplied by WWS-electricity-hydrogen resources no later than 2030 and all existing non-WWS infrastructure to be eliminated no later than 2050. We find that the plan is technically and economically feasible but politically challenging.
