Switching over from internal combustion vehicles to electric won’t be cheap … it really won’t be cheap!

At Spiked, Rob Lyons looks at the British government’s recent decision to ban sales of internal-combustion cars in 2035 rather than the earlier target date of 2040:

First, at present, electric vehicles cost a lot more than those with internal-combustion engines. For example, one car-buying advice website notes that the Peugeot e-208 is as much as £6,200 more than the standard 208 model. There are government subsidies to help with the cost of electric cars (currently £3,500), but can this be sustained if we all switch? It has already been cut from £4,500 in 2018.

That said, while the purchase price of an electric car may be higher, charging is a lot cheaper than fuelling a regular car. Electric vehicles cost between £4 to £6 per 100 miles to charge at home and £8 to £10 using public charge points, while petrol and diesel cars cost £13 to £16 per 100 miles in fuel (although 60 per cent of the fuel cost is tax).

In theory, maintenance should be cheaper, too, given that electric motors have fewer moving parts than petrol or diesel engines. But to further complicate matters, batteries gradually lose their capacity to hold charge over time. They have to be replaced at the cost of thousands of pounds every few years. (The warranties covering battery replacement varies by manufacturer: Tesla, for instance, offers an eight-year warranty, but the Renault Zoe is covered for just three years.)

Electric cars may be cheaper to own overall, but this is largely down to subsidies and tax breaks, including lower vehicle duties and not having to pay charges in low-emission zones. Still, with the entire car industry throwing its efforts into making electric cars cheaper and increasing battery capacity, costs may well come down somewhat, reducing the need for such breaks. Fingers crossed.

The cost to individual owners will be higher, but the costs to build up the electric charging infrastructure will be distributed among all consumers, not just the owners of vehicles:

This brings us to perhaps the biggest problem: where will the power come from and how will it reach us? Eventually shifting all the energy for cars from oil to electricity means producing much more electricity. Greens are pleased that electricity use is currently decreasing, and a greater proportion of electricity is coming from renewable sources. But the arrival of electric cars en masse would demand a whole lot more electricity, mostly to be used at night.

Unless we want to coat the landscape in wind turbines, which are unreliable in any event, we’ll need other sources of power. More nuclear? Fine by me. But will eco-warriors stand for that? Even if we can produce the juice, having lots of cars charging in the same area may overwhelm the local electricity networks. Who is going to pay for the upgrade?

When all of these factors are considered we have to ask if all this effort will really reduce greenhouse-gas emissions anyway. Digging up the resources required to create all those batteries will be hugely carbon-intensive. Perhaps the most likely outcome of banning sales of new petrol and diesel vehicles is that demand for second-hand vehicles will go up. We could end up like Cubans, nursing venerable old cars for years, way beyond their intended lifespans.
