Bjørn Lomborg Counts the ‘Enormous’ Cost of the Wind Power ‘Mirage’

Money Wasted

When it comes to assessing the costs, risks and benefits of environmental policy, Bjørn Lomborg is one of the very few that provide balanced, detailed analysis; properly supported by facts and evidence.

The economic choices we make – about allocating scarce resources to unlimited wants – should – as Lomborg consistently points out – be made taking into account all of the costs weighed against properly measured benefits (see our post here).

Bjørn Lomborg has become one of the most high profile critics of insanely expensive and utterly pointless renewable energy policies across the globe (see our posts here and here and here).

In recent times, he’s courted controversy in Australia (well, more like ‘confected outrage’) over the Coalition government’s plans to fund a research wing of an Australian University, where Lomborg and his fellow research travellers could pitch up and undertake proper (rational) investigation in how to best direct scarce resources at real world problems – like ensuring the world’s poorest don’t have to drink from muddy puddles; and how they might get to enjoy cheap and plentiful electricity – instead of cooking on twigs and dung.

What Lomborg & Co are out to change; and Australia’s
shameless eco-facists are hell-bent on ensuring never does.


Now, while former PM, Tony Abbott was ready to go head-to-head with the thought police that have taken over Australia’s Universities (a small but noisy band of academics and students, drove the proposed centre out of Western Australia), his successor, Malcolm Turnbull (with internal pressure from Greg Hunt’s office) quietly dropped the offer of $4 million in funding altogether.

That spineless retreat came despite the fact that Flinders University in South Australia was ready to welcome Lomborg and his research team (notwithstanding the usual childish hysterics from a few neo-Marxist rabble-rousers).

Before Tony Abbott was knifed by Turnbull, the Flinders Uni offer to accommodate Lomborg was as good as a done deal. But, now, with the funding inexplicably chopped, a wealth of beneficial research will never happen. So much for the Age of Enlightenment …

Proving you can’t keep a good man down for long, Bjørn’s back, with this recent piece published in The Australian – in which he hammers the insane cost and utter pointlessness of tying our energy futures to unreliable and intermittent renewables, like wind power.

Counting the cost of wind and solar

23 October 2015

When considering climate change, most people think wind turbines and solar panels are a big part of the solution. But, during the next 25 years, the contribution of solar and wind power to resolving the problem will be trivial — and the cost will be enormous.

The International Energy Agency estimates that about 0.4 per cent of global energy now comes from solar and wind.

Even in 2040, with all governments implementing all of their green promises, solar and wind will make up just 2.2 per cent of global energy.

This is partly because wind and solar help to reduce greenhouse-gas emissions only from electricity generation, which accounts for 42 per cent of the total, but not from the energy used in industry, transport, buildings and agriculture.

But the main reason wind and solar power cannot be a major solution to climate change stems from an almost insurmountable obstacle: we need power when the sun is not shining and the wind is not blowing.

This has major implications for claims about costs.

For example, wind power, we are told repeatedly, will soon be cheaper than fossil fuels — or even, as a recent global news story claims, it is already cheaper than fossil fuels in Germany and Britain.

This is mostly a mirage; large-scale wind power will not work any time soon without subsidies.

As American business magnate Warren Buffett says: “We get a tax credit if we build a lot of wind farms. That’s the only reason to build them. They don’t make sense without the tax credit.”

The IEA estimates that the annual bill for global wind subsidies will increase in the next 25 years, not decrease or fall to zero.

One reason is that cheaper wind in Germany and Britain is true only for new construction. Most existing coal and gas suppliers cost about half or less than wind and could run for decades; instead, we half-close them to accommodate wind.

While new, cheap German wind-energy producers cost $US80 ($110) a megawatt hour ($US0.08 a kilowatt hour), the average German spot price last year was just $US33 a megawatt hour.

More important, wind is cheaper only when the wind blows. When the wind is not blowing, wind-generated electricity is the most expensive electricity of all because it cannot be bought at any price.

Installing more wind generators makes the electricity they produce less valuable. The first wind turbine brings a slightly above-average price per kilowatt hour. But with 30 per cent market share, since all wind producers sell electricity at the same time (when the wind blows), the electricity is worth only 70 per cent of the average electricity price.

Solar prices drop even faster at similar market shares. So wind and solar generators have to be much cheaper than the average price to be competitive.

Moreover, wind and solar make fossil-fuel-generated electricity more expensive. Some people may think that is a good thing; but, if our societies are to continue functioning in cloudy, windless weather, that means relying on some fossil fuels. The IEA estimates that 56 per cent of electricity will come from fossil fuels in 2040, with nuclear and hydro accounting for another 28 per cent.

Significant wind and solar usage reduces the number of hours gas and coal generation operates; with large fixed costs, this makes every kilowatt hour more expensive.

In a real electricity market, this would result in much higher electricity costs on windless evenings. But this is politically problematic, which is why markets are often constructed to spike much less.

In Spain, gas plants were used 66 per cent of the time in 2004 but only 19 per cent of the time now, largely because of more wind use. Because the plants must be kept running 57 per cent of the time to avoid losses, many are likely to close. Across Europe, possibly 60 per cent of all gas-fired generation is at risk.

Keeping the lights on means accepting much higher prices or emulating what many European governments are beginning to do: namely, subsidising fossil-fuel plants. For example, in 2018 alone, Britain will pay nearly £1 billion ($2bn), mostly to fossil-fuel-based generators, to keep back-up capacity available for peak power usage.

Building more wind and solar generating capacity with subsidies means societies end up paying three times for power: once for the power, once for subsidies to inefficient renewables and once more to subsidise our now-inefficient fossil fuels.

Many will say: “But at least we cut CO2.” That is true, although the reduction is perhaps only half of what is often touted because the back-up power needed to smooth intermittent wind and solar is often more CO2-heavy.

Moreover, we pay dearly for these cuts. In 2013, the world produced 635 terawatt hours of wind electricity and paid at least $28bn in subsidies, or $US76 per avoided tonne of CO2, and likely twice or more than that.

When the estimated damage costs of CO2 are about $US5 a tonne, and a tonne of CO2 can be cut in the EU for about $US10, we are paying a dollar to do less than 7c-13c of good for the climate.

And its positive impact on the climate is negligible.

Consider two worlds: in the first, all governments implement all their green promises, as indicated by the IEA, and increase solar and wind energy more than sevenfold by 2040; in the second, not one new solar panel or wind turbine is purchased during the next 25 years.

The difference in subsidy spending between the two worlds is more than $US2.5 trillion. Yet the difference in temperature increase by the end of the century, run on the UN climate panel’s own model, would be a mere 0.0175C.

One day, when the wind price has fallen much further and solar is almost as cheap as wind, significant investments in wind and solar could be a great idea. But even after decades of capital reallocation, these sources may account for a bit less than a quarter of our electricity.

In short, a world powered by solar and wind — one that has resolved the climate challenge — is very unlikely any time soon.

Bjørn Lomborg: slams the ‘enormous’ cost of the wind power ‘mirage’.

About stopthesethings

We are a group of citizens concerned about the rapid spread of industrial wind power generation installations across Australia.


  1. And why aren’t environmentalists going crazy over the death of endangered birds as they are incinerated by huge solar farms in CA or when they fly into a moving wind turbine? Is death to animals OK now because they have their ugly monstrosities peppered across the landscape? This is the insanity of liberal idol worshipers’ argument about climate change and saving the planet. It is infuriating.

    Warren Buffett on windmill power: “We get a tax credit if we build a lot of wind farms. That’s the only reason to build them. They don’t make sense without the tax credit.”

    From the Godfather of global warming alarmism and former NASA climate chief turned environmental activist, James Hansen, on ‘unreliable’ energy:

    “Suggesting that renewables will let us phase rapidly off fossil fuels in the United States, China, India, or the world as a whole is almost the equivalent of believing in the Easter Bunny and Tooth Fairy.”

    And like the old sailors say, “The wind is free … but everything else costs money”.

  4. This is a damning analysis by this famous luke warmer. Do the estimated damage costs of CO2 include the offsetting benefits I wonder? i.e. is this $US5 a worst case scenario?
