Well, only about 1/3 of the so called global warming is caused by man. Volcanoes, changes in the Van Allen radiation belt, polar shifts, earth tilt has increased, increased solar minimums and maximums, lava rock and basalt that continue to release carbon dioxide long after a volcano, have all contributed far more to global warming than what man has or is doing. China and India use far more coal than the US, so there is that. If people would quit buying Chinese stuff and try to buy from anyone else, that would help.
Also, no one is looking, especially from the left, at the big picture. Windmills have to have transmission lines to where people live. Many windmills are not functioning because they have nowhere to send their power.
Solar is great, but solar farms take up farmland. It would be nice if they would work out agreements to install solar farms over parking lots and on top of larger flat top commercial buildings. Save the forests and farmland.
Both solar and wind need large battery storage to run excess power through when demand is down to level out the power needs.
Germany is making hydrogen from water with North Sea windmills and pumping the hydrogen (20% hydrogen, 80% natural gas) through the natural gas pipeline system to where it is needed like power plants, and using separators to take out the hydrogen at certain gas stations to fuel their cars that run hydrogen instead of gasoline. Gas burner tips in homes and businesses are not affected by 20% hydrogen mix. This cuts down on carbon dioxide produced by burning natural gas. Germany imports all their natural gas, once from Russia through Poland or Ukraine. Now they import liquid natural gas from the US. Heck, just using natural gas instead of coal cuts carbon emissions by about half. Anyway, burner tips for all new appliances could be equipped with steel wool pads to cover the burner tips to glow red if burning pure hydrogen gas. You can't see hydrogen burn. Hydrogen could eventually replace natural gas in the natural gas system that is already in place. Most leaks are from older cast iron mains and threaded pipelines. Welded pipelines and plastic mains and services for under 60 psi are slowly replacing the over 100 year old cast iron and threaded pipelines to eliminate leaks.
There are solutions to alternative energy. However, we are still going to need oil, natural gas, and even coal for the next 30-50 years. There is no way out of it. Gasoline and diesel vehicles can last at least 20 years and new gas and diesel vehicles are still being built and sold.
Solid state cheaper batteries have to be developed to replace more expensive lithium batteries. This hasn't happened yet.
New technology has to be phased in naturally and can't be forced. Otherwise it can lead to higher prices for power, natural gas, propane, gasoline and diesel, hyper inflation for the government spending too much money on the "green new deal".
