The study in Environmental Science & Technology suggests that switching entirely to wind, solar, geothermal, and hydropower by 2050 can reduce energy needs and costs, improve air quality, and slow climate change at a fraction of the cost of carbon capture technologies. Lead author Mark Jacobson argues that investing in renewables over carbon capture is more beneficial, as it eliminates not only CO2 emissions but also air pollution. The study compares two extremes to highlight the advantages of renewable energy, stating that eliminating combustion is the most efficient way to address climate change. The authors emphasize the importance of prioritizing renewable energy sources for a sustainable future.
