The devastating Russian invasion of Ukraine has captured global attention. While the world’s focus is rightly on the human toll and suffering, the crisis has highlighted the need to end reliance on Russian oil and gas. To achieve that ambition we must be pragmatic and invest in sensible alternatives, not engage in wishful thinking about renewable energy.

Every single day the world spends more than $1bn on fossil fuels from Russia. As Ukrainian foreign affairs minister Dmytro Kuleba tweeted, that money is now paying for the “murder of Ukrainian men, women and children”. We must end this reliance.

However, this has proved easier said than done: over dozens of years the world has exchanged trillions of dollars for fossil fuels from the Soviet Union and now from Russia. Our continued use of Kremlin-backed oil and gas reveals two inconvenient truths.

  • Reliable energy maintains the foundation of modern society and few are willing to give up its benefits. Access to cheap, abundant and dependable energy has been the cornerstone of the Industrial Revolution and humanity’s achievements; and
  • We have been sold a largely untrue story that renewables can give us energy independence. Campaigners and governments have promoted the idea that renewables can replace fossil fuels and still provide cheap, abundant and reliable energy, which would crucially deliver energy security while solving the challenge of global warming. The Russian invasion has exploded this myth and revealed it as nothing more than wishful thinking — especially for the EU.

For decades, the EU has claimed that renewables can deliver energy security because this can be produced at home and does not need to be imported. But the key renewables, solar and wind, are unreliable because they work only when the sun is shining or the wind is blowing. To achieve reliable power 24/7 solar and wind need backup, provided by burning gas. Thus, the EU’s green energy policy contributes to it paying Russia more than half a billion dollars each day, mostly for fossil fuels and especially gas, to provide a backstop for European solar and wind.

Solar and wind campaigners claim batteries can be game-changers when the sun isn’t shining and wind isn’t blowing. In truth, all the batteries in Europe can store power for just one minute and 21 seconds of the continent’s average electricity demand — after that we’re back to relying mostly on fossil fuel backup. By comparison, in winter Germany experiences wind lulls lasting more than five days.

Moreover, electricity makes up just a fifth of Europe’s overall energy consumption, nearly three-quarters of which is met by gas and other fossil fuels. Despite the hype, solar and wind deliver less than 4% of Europe’s total energy. When German Chancellor Olaf Scholz insists renewables will make Germany “independent and less susceptible to blackmail” he is missing the point, because inefficient solar and wind do not help avoid cold homes. Electricity only delivers a tiny part of heating, with gas providing almost 40%.

Much more energy comes from the world’s oldest energy source: burning wood. While in principle it is renewable, increasing the area of forests being cut down can have huge biodiversity effects. Moreover, wood emits more CO than coal when burnt and it is often imported and transported on diesel ships from the US. Currently 60% of the EU’s total renewable energy comes from burning wood pellets.

The takeaway is that we need better alternatives to Russian oil. Germany just shut down three nuclear power plants and is scheduled to shut down three more by the end of the year. But shutting down existing nuclear power plants is plain dumb. All the big costs have already been incurred, so keeping them running not only delivers energy independence but provides incredibly cheap, reliable and CO-free power.

Europe should also reconsider producing its own natural gas through fracking, like the US did. It has plenty of potential sites in Poland, France and Romania. Fracking could deliver cheap energy and complete energy independence — it has reduced US emissions dramatically. While there are genuine concerns around fracking, most can be dealt with by good regulation.

Unfortunately, most of Europe has rejected fracking because of exaggerated fears, spread with financial help from Russia. Yet US studies clearly show the overall benefits from fracking vastly outweigh additional costs.

To achieve true independence we need to look further and study realistic alternatives. We must demand more than breezy aspirations for more solar and wind. We need to invest in research & development (R&D) across a wide range of potential energy sources. For example, while building more of the current third-generation nuclear would deliver safe and reliable energy, its construction is currently way too expensive. R&D into fourth-generation nuclear could potentially let us generate huge amounts of power at low cost.

Concerted research will not only deliver energy independence but will also offer a realistic solution to the long-term climate problem. This research will take time, so for the short run fracking is the most pragmatic option. With sensible regulations it could generate plentiful, cheap gas and huge economic benefits, while reducing emissions. Crucially, in the shadow of Vladimir Putin’s war, this could be a relatively quick and realistic way for Europe to move towards energy independence.
