Mark Jacobson in his book Renewable Energy and Storage for Everything has laid out a plan to convert virtually all energy use in the world from fossil fuel to electricity. He includes such things as
of all new EV sales. Germany and China also have incentives and regulations that encourage and require EV adoption.
Most other countries with large vehicle sales have exceeded the 5% or 10% adoption rate that is the typical indicator of a new technology market takeover. Even in the US — where Tesla, GM, and Nissan have nearly or completely exhausted federal subsidies — the new BEV adoption rate has already reached 5.6%. The biggest problem now is switching a massive automotive industry to EVs and manufacturing enough batteries to power them.
We can only hope that enough political pressure can be brought to bear to raise this number to close to 100%It is quite possible that total world new electric vehicle adoption will be over 50% of new vehicle sales within 5 years, However, even when it approaches 95%, it will be at least another decade before the total fleet numbers will match those numbers.: All air conditioning has been totally electrified using heat pump technology since widespread adoption began in warm climates in the 1960s.
Europe in general and Germany in particular are facing the threat of blackmail by cutoff of fossil gas from their Russian supplier. If Germany is going to avoid freezing homes this coming winter, it must conduct a massive conversion to heat pump technology in a very short period of time. It may also get some liquified fossil gas by ship from the US and other countries, but that will not nearly compensate for a complete cutoff of the fossil gas pipelines from Russia this winter.
