Many of the arguments have centered on peak power - now plus charging all or many of the electric cars on top. The future is charging when there is a surplus of energy eg. 12-4am and static charging of powerwall 2 type devices at services or even public charging. They charge when electricity demand is low and cheap and discharge when people need it for cars or the house.

£40-50K for a Tesla (many more options in 2010, incidentally at 0-2% Benefit in Kind rates for next few years) plus massive fuel and servicing cost savings. 1-6p a mile depending on whether economy 7 and type of journey.

"In the third quarter of 2019, some 39% of UK electricity generation was from coal, oil and gas, including 38% from gas and less than 1% from coal and oil combined.
Another 40% came from renewables, including 20% from wind, 12% from biomass and 6% from solar. Nuclear contributed most of the remainder, generating 19% of the total.
While it is unlikely that renewables will generate more electricity than fossil fuels during the full year of 2019, it is now a question of when – rather than if – this further milestone will be passed."
"Over the past year, the most significant reason for rising renewable generation has been an increase in capacity as new offshore windfarms have opened. The 1,200 megawatt (MW) Hornsea One project was completed in October, becoming the world’s largest offshore windfarm. The 588MW Beatrice offshore windfarm was completed in Q2 of this year.
These schemes add to the more than 2,100MW of offshore capacity that started operating during 2018. Further capacity is already being built, including the 714MW East Anglia One project that started generating electricity this year and will be completed in 2020.
In total, government contracts for offshore wind will take capacity from nearly 8,500MW today to around 20,000MW by the mid-2020s. The government and industry are jointly aiming for at least 30,000MW of offshore wind capacity by 2030, with two further contract auctions already expected."

"The UK is to get its first subsidy-free offshore windfarms after the government awarded contracts today for nearly 6 gigawatts (GW) of capacity, at prices below those it expects on the open market.
The prices are so low that the windfarms could generate electricity more cheaply than existing gas-fired power stations as early as 2023, Carbon Brief analysis suggests"
Big electricity demand 4-7pm (or similar). Surge prices and grid under high load. Midnight to 4am, sometimes plunge prices (negative - the suppliers pay users).
An answer is to have electric storage (domestic/commercial) and cars/lorries/buses charge during the electricity gluts - possibly at a profit with potential to sell back at a profit during peak hours (article in metro/evening standard or other free rag mentioned £400+ per year). https://en.wikipedia.org/wiki/Vehicle-to-grid - "A 2015 report on potential earnings associated with V2G found that with proper regulatory support, vehicle owners could earn $454, $394, and $318 per year depending on whether their average daily drive was 32, 64, or 97 km (20, 40, or 60 miles), respectively."
Plus Japan is encouraging Vehicle to Grid to help after natural disasters. Japanese car manufacturers are pursuing (IMO) the daft idea of fuel cell driven electric-drive vehicles - but this article talks about a 2 cent per KWH difference generating $5000 per year - https://www.fleetcarma.com/electric-vehicles-relief-japans-grid/
90-95% of all electric vehicle charging is done at home. Roughly £9 for 300 miles for me (bad case would be 200 miles in exceptional weather). Worst case for electric is a series of short winter stop-start journeys or autobahn speeds. First is bad because heating the car repeatedly is a waste. Second is bad as drag increases (squared?) at speed. Best cases would be Solar / powerwall or economy 7 (£3?).
I've just computed my real world cost for 1100 miles of spectacularly sub-optimal EV driving. A few long drives in torrential rain (harder to push out of the way) loaded up with people and kit and most journeys of just 3 miles to/from train station with pre-heating of car (from phone app) so it's demisted, toasty and even on one morning defrosted. So more energy spent on heating than driving probably. Roughly £75 - 6.82 pence per mile.

"Only a few gas stations remain operational in CA amid the power outage, resulting in long lines of vehicles as owners attempt to acquire fuel. Ali Alezzani, a manager of an Exxon station on San Pablo Avenue in El Cerrito, noted to the Chronicle that tensions are currently so high, some gas car owners almost got into fights while they were waiting for their turn at the pump. Videos taken of gas stations across the state hint at extremely long wait times as large numbers of car owners line up for a chance to acquire fuel.
...
Amidst the chaos surrounding the state, Tesla owners who purchased a Powerwall 2 battery with rooftop solar systems have reported that they are barely feeling the effects of the ongoing outage. Mark Flocco, a homeowner who acquired two Powerwalls for his home, noted in a Twitter post that his battery units have been powering his house with no issues since the outages started.
...
While Tesla owners with residential battery systems and solar panels are practically immune to the effects of PG&E’s widespread shutdown, CEO Elon Musk has pledged to improve the company’s Supercharger Network by installing Powerpack batteries within the next few weeks. Musk also mentioned that solar panels will be added to its Superchargers as fast as possible, in order to acquire clean, 24/7 power. "
In short, electric vehicle and static storage can help with the grid (https://en.wikipedia.org/wiki/Grid_energy_storage#Examples).
This is why all OLEC grants for electric vehicle charging require smart 'chargers' (EVSEs). The high-power 400V chargers at service stations (rarely used by electric car drivers except for long journeys with no destination charging) only need some electric storage to even out demand from peak and could easily generate money from plunge / peak pricing.

You tax land, not food, not shares.
And specifically the economic usefulness of land to the owner. ie moorland - virtually zero (zero if right to roam allowed?).
By exclusively using land you prevent others from using that land. Former farmland with planning permission may be worth 100 (probably more) times as much as the farmland was.
What has changed? Who reaps the economic windfall? Who received a bribe to help?
Valuation - Land Valuation Office used to do it well and routinely until they were stopped. Rental values can be used, but many countries did or do it well.
Otherwise lots of mechanisms - how's this for a fun one? Self set your own tax and let anyone buy the asset at a multiple of the tax you pay....
Council tax is banding into bands with upper limits. It's contrived. A Westminster mega-mansion pays a bit more than an average bod
