A study published in Environmental Science & Technology proposes that transitioning to sourcing energy entirely from wind, solar, geothermal, and hydropower by 2050 could lead to a reduction in energy needs, costs, and air pollution, ultimately aiding in slowing climate change. The research, led by Mark Jacobson from Stanford University, highlights the advantages of investing in renewable energy infrastructure over carbon capture technologies in terms of cost-effectiveness and environmental benefits. The study compares scenarios where countries shift to renewable energy sources versus maintaining reliance on fossil fuels, showcasing the significant health, climate, and social benefits of adopting renewables. By eliminating fossil fuels and biomass combustion through renewables, countries could potentially decrease energy needs by over 54% and cut annual energy costs by nearly 60%, while avoiding millions of air pollution-related illnesses and deaths. The authors emphasize the importance of prioritizing the elimination of combustion through renewable energy adoption for a more efficient and sustainable energy future. They argue against policies that promote carbon capture and direct air capture, advocating for a complete transition to all-renewable energy sources as a more effective solution to tackle emissions and climate change.
