A new Stanford University study finds that replacing fossil fuels with renewable energy is significantly more effective — and far less expensive — than relying on carbon capture technologies.
Published in Environmental Science & Technology, the research shows that a full transition to wind, solar, geothermal, and hydropower by 2050 could cut global energy use by over half, lower energy costs by nearly 60%, and prevent millions of deaths from air pollution.
In contrast, the study argues that large-scale carbon capture — whether from smokestacks or the air — adds costs, increases energy demand, and delivers fewer environmental benefits.
Lead author Mark Jacobson explains that even if powered by renewables, carbon capture diverts clean energy away from displacing fossil fuels, making it an inefficient strategy.
“It’s always better to replace the source of emissions than to clean up after them,” he said.

The study compares two global scenarios: one powered entirely by renewables, and another that keeps fossil fuels and adds carbon capture systems. The results strongly favor renewables-only strategies.
The authors argue that policies promoting carbon capture alongside clean energy are misguided.
“The only way to eliminate all air-pollutant and climate-warming gases and particles from energy is to eliminate combustion,” the study concludes.
