Technology advances and new products are accepted when they provide consumers with something that improves their lives, esp in the short term. Renewables, EVs, etc are currently accepted by a relatively small percentage because they believe in the cause and are willing to accept the trade-offs including cost, inconvenience of charging stations, etc.
Many, many people do not want their current fossil fuel powered cars, homes, tools, etc. taken from them. And many believe that drastic changes in the name of almost insignificant improvements from the climate change movement are not worth it. These will be huge barriers to large scale conversion even in developed countries. This, along with much more difficult technical barriers to overcome (aircraft, trucking, heavy machinery, etc) will likely sustain fossil fuels as a primary energy source for many years to come in developed countries. Undeveloped countries will need fossil fuels even longer.
Good advice on any topic should never be taken from a site like this. Do your own research.
