Professor John Raine: Climate And Energy Policy Realism Not Virtue Signalling, Please

Saving the Planet with Formula 1 Design Regulations

The 2026 Formula 1 (F1) motor racing season gets under way in Melbourne 6-8 March. During pre-season testing in Barcelona and Bahrain, leading drivers such as Max Verstappen, Lewis Hamilton and Fernando Alonso weren’t holding back with their criticism of the new FIA design regulations.

The sustainable non-fossil fuel is not really an issue, although “sustainable” needs close scrutiny as too often some environmental and emissions costs are externalised. The key change is that the FIA has specified an increase from 120kW to 350kW (close to 50%) electric power, and a reduction from ~550kW to ~400kW from the 1.6 litre turbocharged internal combustion engine. Notably, the battery energy storage capacity of 4 megajoules for 2026 remains unchanged, with this energy to be recovered twice over in braking each lap. Drivers now have become electrical energy managers rather than being 100% focused on driving flat out.

The FIA is tipping its cap to climate change and in the process annoying drivers and likely thousands of spectators. Why have they done this other than to be very visibly virtue signalling?

The F1 circus involves not only the vehicles, support engineering, crews and drivers travelling by air between venues, but also tens of thousands of spectators travelling sometimes long distances to F1 race weekends. A colossal amount of fossil fuel is burned to support this sport and bring spectators to race venues. A quick calculation indicates that just one Lear Jet carrying a billionaire and a few friends for several hours to the next race will use far more fuel than the entire F1 field does during a single race weekend.

Sure, applaud the FIA for driving advances in hybrid engine technology. But, F1 racing cars use a miniscule proportion of the total fossil fuel consumption that can be attributed to this sport. The new regulations seem to be yet another piece of ESG theatre which will potentially detract from an out-and-out tussle for driver supremacy.

Did the FIA sign up for the 2015 Paris Climate Agreement? I don’t think so, but New Zealand and around 200 other countries did. The new F1 racing regulations have much bigger parallels in government carbon emissions and energy policies worldwide.

Climate Science – Not Settled

We live on a planet whose climate has been changing through geological time, and which has been gradually warming for 20,000 years, but with recent accelerated warming [1]. The IPCC [2] attributes to human activity all of the increase in resident atmospheric carbon dioxide (CO2) from around 280 ppm in pre-industrial times to around 430 ppm today.

The temperature effect of natural ocean-atmosphere cycles, volcanic eruptions, variation in sun’s radiation, planetary orbits, and Earth’s axis precession make modelling of climate change extremely complex. Atmospheric scientists such as Lindzen and Happer [3] state:

“Water vapor and clouds account for more than 90% of the atmosphere’s ability to intercept heat. Thus, CO2 and all the other GHGs account for less than 10% of the atmosphere’s ability to intercept heat….. the common assumption that carbon dioxide is in the IPCC’s words “the main driver of climate change” is scientifically false.”

Despite much alarmism around extreme weather events increasing, care is needed to distinguish between periodic changes in weather patterns and real longer term climate change. Nonetheless, the ~1⁰C temperature rise since the beginning of industrialisation means the atmosphere can hold about 7% more water vapour now, and we will see more heavy rainfall events.

The predominant climate change narrative is alarmist, with the IPCC forecasting a temperature rise of 2 – 5 ⁰C from around 1900 to 2100. The upper end of this range is extremely unlikely. Coe et al. [4] found future temperature sensitivity to rising CO2 levels falls exponentially with further CO2 increases. They note:

“The two main atmospheric greenhouse gases are water (H2O) and CO2. Climate sensitivity to future increases (a doubling) in CO2 concentration is calculated to be 0.50°C, including the positive feedback effects of H2O, while climate sensitivities to CH4 and N2O are almost undetectable at 0.06°C and 0.08°C respectively. This result strongly suggests that increasing levels of CO2 will not lead to significant changes in earth temperature and that increases in methane (CH4) and nitrous oxide (N2O) will have very little discernible impact.”

However, even if one accepts the IPCC position on anthropogenic CO2 and global warming, the following still hold:

• New Zealand produces less than 0.1% of world CO2 emissions. If we achieve Net Zero, which will be at more than $500 Bn cost [5], it would have no measurable effect on global CO2 levels or temperatures – i.e. ~zero climate impact.

• If every one of the 200 signatory countries kept their 2015 Paris Agreement promises until 2100, even IPCC climate models tell us that the world would be a trivial 0.17° cooler [3]. To date, at least 27 countries [footnote 1] have failed or reneged on their Paris Climate Agreement commitments.

Whatever one’s position on climate change, the science must never be seen as settled, and climate science has been unfortunately politicised to foster an alarmist view. We should, of course, move forward with care as some climate change adaptation is needed, but New Zealand cannot justify the economic damage to our farming or manufacturing industry sectors of pursuing Net Zero 2050 or taxpayer commitments under the 2015 Paris Climate Agreement, or the Emissions Trading Scheme.

The New Zealand Government has stated its continuing commitment to the Paris Agreement and to Net Zero 2050. This at a grander scale parallels the new Formula 1 regulations - a policy that can only be seen as climate change virtue signalling in the face of zero impact from intended actions.

Is our energy policy similarly captured by a fixation on decarbonisation rather being realistic and pragmatic?

New Zealand’s Energy System [6]

Societies throughout history have needed reasonably priced high-density energy to make major economic progress: e.g. coal in the industrial revolution, and later oil, gas and nuclear energy.

New Zealand faces energy shortages and January 2025 saw spot electricity prices of $2,000 - $3,000 per MWh during a low wind period, and daily averages above $500/MWh have occurred during tight hydro periods.

Government and our power industry appear to be planning on the assumption that:

(i) Electrification of transport, industry & commerce will proceed apace with a doubling of electricity demand by 2050.

(ii) Net Zero 2050 will be achieved by big increases in wind and solar power, and some battery back-up.

(iii) Market forces will deliver a reliable and economic supply. The focus on wind/solar and batteries seems once again to be climate change virtue signalling, or is it just blind faith trumping real world experience?

There is a belief that the public will tolerate periodic rotating blackouts and that the necessary back-up can be largely provided by demand response from grid-connected electric car batteries and domestic rooftop solar power batteries. The public will not like this. It is also costly and not the solution claimed by some. The cost to the economy of shortages and industry interruptions is already billions of dollars and we cannot afford to see more industry closures such as paper production at Tokoroa’s Kinleith Mill and Winstone Pulp International’s Karioi and Tangiwai sites.

Wind and solar power are cheap and getting cheaper at the power station gate due to massive production in China, but they are ultimately the most expensive option to the consumer, as shown by power prices in countries such as Germany, The Netherlands, Denmark, Germany and the UK. This is because of

• The need for ~50% capacity high inertia turbine back-up (gas or coal assuming hydro and geothermal fully utilised) to cope with windless cloudy weather (and nighttime).

• The operating life of only 15 - 25 years compared with 60 - 100 years for hydro, geothermal, gas, coal and nuclear power.

• The eye-watering cost of current-technology large battery storage. e.g. The Genesis Huntly battery system will deliver 200MWh, enough for 66,000 homes for just 2 hours, at a projected cost of $150 million. Moreover, the operating lifetime for both lithium-ion and sodium-sulfur batteries is only about 15 years. New battery technology is needed long-term for EVs but will be critical for stationary mass energy storage if this is to become economically viable.

There is also the major risk of grid instability with high percentage solar/wind systems (e.g. the grid failure in Spain 28th April 2025). A stable electricity grid requires a predominantly high-inertia system, that can maintain stable frequency: i.e. turbine systems fuelled by coal gas, nuclear power, geothermal and hydro (when we are not in dry years). Wind and solar struggle to do this with electrical voltage and frequency stabilisation.

By 2050, it is forecast that we will have over 11 GW of combined solar and wind power capacity backed up with 2.3 GW in large scale batteries. In reality around 5 GW back up battery capacity would be needed, unless we add more than another 1GW each of hydro and geothermal capacity.

Expensive electricity has closed down many heavy industries in Europe, especially in Germany and the UK. The UK has shut down most coal-fired stations and imports ~10% of its electricity via submarine cables, but Germany is now re-commissioning coal-fired power stations.

We need more fast-start open-cycle gas turbine (and coal-fired) generation in the short term. Nuclear energy should form part of the long-term plan. Relying mostly on more solar and wind power will consign us to a very expensive energy future.

The planned LNG terminal is also very much an interim measure. To give us system resilience, New Zealand needs a realistic energy plan that includes new gas fields, more hydro and more geothermal. This needs a cross-party accord on gas field exploration that gives international investors and drilling companies the confidence to engage. If we expect a prosperous future for New Zealand, Labour and the Greens must better understand the technical and economic realities of our energy system.

Rather than virtue signal on energy policy, let us do practical and effective things like building better insulated homes, moderating emissions, better managing our environment, and using fossil fuels prudently, since these do not regenerate on human time scales. We should drive small, lightweight vehicles where practical - 90% of fuel energy around town is used in accelerating vehicle mass up to speed. The Australasian average vehicle weight and engine size are larger than in Europe, although the USA takes the world gas guzzling prize.

There are large, vested interests in maintaining climate change anxiety: political to increase the span of influence on national policy by the UN; commercial as mega-corporations have massive interests in wind/solar renewable energy and the EV industry. Environmentalist author Michael Shellenberger [7] has discussed how vested interests have demonised fossil fuel-fired and nuclear power plant in favour of solar and wind.

Clear thinking about our energy and emissions future is needed, grounded in a realistic view of climate change. No doubt virtue signalling will continue in high profile operations such as F1 motor racing, in government announcements, and through greenwashing initiatives like the high-net-carbon-emissions and environmentally damaging Auckland food scraps recycling scheme [8]. In the end, governments must take pragmatic decisions in order to protect their national economies.
