Also, using renewable electricity to replace electricity produced by carbon-intensive energy sources, for example, coal, would likely result in a greater reduction in emissions than using that electricity to convert CO 2 into liquid fuels. Furthermore, the main competing reaction to CO 2 reduction is hydrogen evolution.
