(N.B.: I'm not anti EV)

Enjoy the overnight cheap electricity while it lasts. The only long-term strategy is investment in solar and batteries – use your temporary savings the government is giving you to invest in solar etc. Some governments are signalling that we have a role to play in electricity infrastructure investment...

Governments are only temporarily letting you get away with not paying the 0.35-0.80 EUR fuel duty on each litre of petrol/diesel (which then has VAT added. These taxes amount to 100s of billions a year across all of Europe). UK is steaming ahead with a per-mile tax on EVs and hybrids, for example.
