I think that had we had a different president than Trump, we would be well on our way to creating a future that is less polluting than is our present fossil fuel one. We could easily have begun installing millions of solar rooftop arrays across the nation and built highly efficient non polluting solar and wind plants to replace fossil fuel plants as they end their useful life. We could begin creating the electric vehicle future that is possible now but wasn't yet only a few years ago.
All this would have produced millions of jobs and increased revenue but instead we are being pushed into maintaining an obsolescent and hazardous technology because a relatively few people make an obscene amount of money if we do so.
Sure they could invest in these new saner energy technologies but out of greed and perhaps an arrogant spite, they choose not to. They are almost asking >>> "Why do we have to work to make the change over when we can keep making money now simply by leaving things as they are?" So they engage in denialism so they don't have to face the moral implications of what they are doing nor admit to the damage that they are doing to the planet!
We could live pretty much like we do (not ever needing to give up our cars and trucks) if we made them all electric. We could create an energy surplus civilization which would be amazing to experience. Imagine never needing to worry about energy for anything!
Btw... I am an American and proud to be a progressive one fighting with an independent mind for a sustainable future. I am not an amerikan nor a murikan et al. I am an American who opposes the corrupt and unpatriotic elites that this country's people fought to be free of (twice) and who fought and defeated the fascists in the last century and now willingly joins with all other progressives around the world to save our planet. I am a patriotic American opposed to war and social injustice... it's the other guys who are those people you call amerikans.
