Toisessakin artikkelissaan Lomborg toistaa laskelmansa:
Bjorn Lomborg: Electric Car Subsidies Are a Bad Investment Ultimately, the reason electric cars are championed is because of their promised emission reductions. Yet the IEA estimates that even if the whole world achieves all of its ambitious stated electric vehicle targets by 2030, the additional saved CO2 emissions over this decade will be 235 million tons. The standard climate model used by the Intergovernmental Panel on Climate Change reveals that this will reduce global temperatures by only 0.0002°F by 2100.
Electric vehicles will only take over when innovation has made them better and cheaper than gas-powered cars. But politicians want the change now and are planning to waste hundreds of billions of dollars subsidizing electric cars, blocking consumers from choosing the cars they want, to achieve virtually nothing for the climate.

Eli 1/10 000 celsiuastetta, 0.0001°C. Menisi jo aika hurjaksi desimaalien käytöksi, jos arvioisimme, paljonko EU:n/Suomen käyttämät
sadat miljoonat eurot tuota lämpötilaa laskevat. Ja on siinä vielä tämäkin:
The reality is far more muddled than the boosters of electric cars would have you believe. Carbon emissions from an electric car depend on whether it is recharged with clean or coal power. Moreover, battery manufacturing requires masses of energy, which is today mostly produced with coal in China. That is why the International Energy Agency estimates that an electric car using the global average mix of power sources over its lifetime will still emit about half as much CO2 as a gas car. You can buy that same carbon emission reduction on America’s longest-established carbon trading system for about $300. Yet many countries pay more than 20 times that amount in subsidies to convince people to make the switch.

Ikävä tosiasia:
They Can’t Make Green Energy Using Only Green Energy Not being a dope, you likely realized a long time ago that it was going to take a lot of energy to manufacture the components of the future green energy utopia. Wind turbines, solar panels, electric cars, and so forth — there is lots of steel, other metals, and silica involved that all need to be melted at high temperatures to get formed into the devices. How are they going to achieve that at reasonable cost using just the wind and sun as energy sources?
Up to now, the main strategy has been to buy most of the devices from China, where they are made largely using energy from coal. Out of sight, out of mind. But both Europe and the U.S. have made an effort to get at least somewhat into the game of making these things. Europe finds itself leading the acceleration into the green energy wall, with the intentional suppression of fossil fuel production and now the substantial cutoff of Russian gas supplies causing sharp spikes in the prices of both gas and electricity.
