Trouble is, it will take decades upon decades to migrate 1.6M vehciles to electric, yet if a Govt wanted to replace Huntly with green energy that would take far less time. Plus, Hybrids are the go, as they are well priced
I fear you are probably right about the vehicles. The cost of EV and ICEV ownership will probably remain about equal.
When everyone is driving EVs and flying electric planes (or not driving and flying at all, as we saw somewhat during the covid-19 lockdown), oil in the ground will be near worthless. So oil producers need to get it out of the ground and sold before EVs become ubiquitous. So as the price of EVs decreases, the price of oil will also reduce to remain competitive. World oil reserves are about 47 years at current usage... that might stretch to 100 years as more people move to EVs.
