Well, it does seem contradictory that OSHA/EPA "over regulated" the industry, yet--"saved countless lives." What you don't see is all the people who didn't sicken and/or die because of stringent pollution controls that have been in place for decades. That's a benefit that's been largely invisible to most people, as is just about any prevention effort in just about any context. And I think we can agree that we'd rather have "too much" workplace safety than not enough.
Biden's energy policies are sensible. He wants to move toward renewable energy, which is the future no matter how much Republican politicians in fossil fuel states bleat. I would expect that the current mess shows us exactly why we shouldn't be dependent on fossil fuels. Every time there's a loud fart in an oil-producing region, we freak out. I'd rather live in a society where we don't have to pay attention to whatever crazy person is trying to start a war in Europe or the Middle East. And renewable energy is the way out of that.
When you say that regulations add costs, you're overlooking the fact that a LACK of regulations can be far, far more costly. Those costs manifest themselves in what economists call "negative externalities"--they're costs that aren't borne by the producers of an economic activity. People's lives are shortened, and their quality of life diminished, in polluted environments. Those are real, concrete economic costs--just harder to express in terms of dollars and cents.
I think that the GOP's demonstrated indifference to the environment and its servile worship of the fossil fuel giants hurts them at the ballot box. Maybe not as much as it should, when its orange god babbles nonsense about renewable energy sources and appointed oil industry lackeys to environmental stewardship posts. Clean air and water shouldn't be a partisan issue.
We don't HAVE to buy fossil fuels from Russia--the American oil cartel has CHOSEN to do so. And the pipeline kerfuffle is silly, because a pipeline doesn't increase the supply of fuel any more than damming a river increases the amount of water flowing in it. Fossil fuels are already obsolete, so we shouldn't be ramping up their production, except in the very short term. But we have too many politicians who are paid employees of the fossil fuel industry--fossils themselves.
