There are more things happening to affect the climate than burning fossil fuels.
One is the solar min-max. They sun goes through 7 year cycles where sometimes it burns hotter than others.
Also, solar flares can affect the Van-Allen radiation belt protecting the earth. The belt is opening up in the southern hemisphere for some reason unknown. It is affecting the climate of South America, South Africa, and Australia.
Another thing is the magnetic poles may be shifting. True magnetic north was coming down to Canada at one time, now it is going down into Siberia. If they switch, that will drastically affect the weather.
Another is volcanoes. One volcanic eruption can spew out enough carbon dioxide to equal everything man does in one year.
So, all these are affecting the weather far more than man and we can't do anything about it.
I'm not against using alternative energy like solar or wind, but it has to be cost effective. Same with electric cars. Cost effective on cars means lower price, longer range, and faster recharging times. Solar and wind have been around for a long time. Many off grid homesteaders use both to help cut their utility bills. Mostly homemade stuff. One of the things I saw was using clean 55 gallon drums painted black and put on an elevated platform. Underneath was a shower. These homesteaders would take showers in the evening under these drums after they warmed the water in the sun all day. Great in summer but not so good in winter as the shower was outside. They built a wall around it and had a door for privacy. There was a lot of room under it.
Building a semi-underground home takes advantage of the consistant temperature of he earth. In Alabama 3' underground is a constant 60 degrees year round. I know a guy in Auburn, Alabama that built an underground home and had the living room or great room area open to the north, all the other rooms were underground, bedrooms, bathrooms and utility room. Kitchen was open to the dining area which was open to the living area. He and his wife lived it it for a whole year without heat and AC. It got down to 14 degrees on or two days that winter. It got down to 60 inside and he used a fireplace to take the chill off. That summer it got up to 102 degrees for a few days. He said it was 85 degrees inside. He said the humidity was bad due to showers, laundry etc, so he installed a central AC. However, he doesn't have to use it as much as a home. This home had 2200 sq. ft. This was before LED lighting so new lighting would save a lot of heat. He did also install a dehumidifier for winter.
I think the best alternative is a plug in hybrid car or truck. For short around town trips under 45 mph you would use electric. For long distance you would use the gasoline + electric for acceleration only. It would get great mileage and the cost is between a gasoline and a total electric vehicle. You could charge them up at home or if the battery is drained, use the motor on the car for about 20-30 minutes to get the electric batteries charged for acceleration. Best of both worlds. Prius cars are the oldest on the road and after 10 years their batteries only lost about 10% of its full charge rate. Still 90% good. Toyota is going hybrid route due to the cost of lithium and cobalt used in the batteries. Tesla is using iron instead of cobalt but the range is lower on their model 3's, but that helps keep the model 3 cost down.
Another alternative is hydrogen fuel cells to produce electricity for an electric drive on cars. One company built a hydrogen fuel cell car that got about 1,000 miles on a fill up of hydrogen. Water is the by product of a hydrogen fuel cell. So roads might be wet all the time. There is no hydrogen infrastructure to support these cars and hydrogen has to be liquified at -400+ degrees which can be dangerous. However, several German companies are going this route making hydrogen out of water and pushing it through the natural gas system in Germany.
Anyway, solar panels are coming down in price, but battery storage is not. You have to store the power when the sun is shining, and you are not using it and also for night use.
Still a lot of stuff to work out, but forcing people to use alternatives when they are not all in place and cutting off supplies of fossil fuels before alternatives are in place is foolish.
