And there are a plethora of ways to generate electricity cleanly. Nuclear, wind, solar, hydro. You know who has lobbied against these heavily? The oil and gas and coal industries, because it would hurt their profits if we used clean energy. Coal and natural gas account for 98% of the emissions from electricity generation in the US.
You know another major contributor to emissions? Transportation. Having efficient mass public transportation would eliminate a huge amount of emissions, and we would have more walkable cities with a healthier population. You know who has lobbied against that for decades? The auto industry because it would hurt profits if people didn’t need to buy a car to get anywhere.
Chevron, BP, Exxon, and Shell make up 10% of carbon emissions just between those four companies. All lobby heavily against green energy and public transportation because it would hurt profits.
