The obsolete technologies are artificially kept alive through direct and indirect government subsidies. The only thing that stops us from reducing carbon emissions is that we don't choose to reduce carbon emissions.

Electric cars are too expensive? Just build more of them and the price will go down. Battery storage is too expensive? Just build more and the price will go down. Renewables are too expensive? Just build more and the price will go down.

It's a matter of choosing the new technology and right now nobody is choosing. Lots of people are proud about polluting the environment and I don't think I can change their mind, the government can't. We all know what this means: nothing can.
