There are forgivable intellectual and policy errors, and then there’s the self-delusion that has driven the West into its dependence on Russian President Vladimir Putin’s oil and gas. 

Russia has long been a major supplier of energy to Europe. The depletion of natural-gas reserves in the West has played a role in Russia’s increased significance. Moscow has also benefited, though, from Europe’s deliberate choice to attempt a great leap forward into a green-energy future, especially in Germany, which decided to turn its back on both nuclear and coal. 

In taking this route, Europe made a holiday-from-history decision to forget the incredible power of oil, gas and coal — the most reliable and efficient sources of energy the world has ever known — and ignore the inevitable centrality of energy to geopolitics. 

Greta Thunberg, the teenage climate extremist who has been elevated into an oracle of all that is good and true, demanded nothing less. 

The world hasn’t embraced fossil fuels out of hatred of the planet but because they are so incredibly useful. If they didn’t already exist — thanks to sunlight and plants that lived millions of years ago — we would have to invent them. Except we wouldn’t be able to. 

Oil is a miracle fuel. Alex Epstein of the Center for Industrial Progress writes that it is “almost eerily engineered by natural processes, not just for cheapness, not just for reliability, not just for scalability, but also for another characteristic crucial to a functional civilization: portability.” It powers cars, trucks and jets, without which the modern world as we know it wouldn’t exist. 

Coal, too, Epstein notes, is affordable, abundant and easy to extract and transport. There is a reason that developing nations invariably turn to it to power the industries crucial to economic advancement.  

So it shouldn’t be a surprise that fossil fuels are still the leading source of global electricity, with coal accounting for 36.7% and gas 23.5%. The total fossil-fuel contribution, at 63.3%, is down only slightly from two decades ago. 

In terms of overall energy, fossil fuels are an even larger proportion, 84.3%. 

For its part, green energy — wind, solar and other renewables — accounts for around 10% of global electricity and even less of total energy. 

Vladimir Putin knew this and understood the power it gave him, even if European policymakers wanted to evade the matter. 

Did they not notice that coal was the mainstay of Britain’s rise to global power in the 19th century? 

Did they forget the role of oil in World War I and World War II, let alone subsequent 20th century history? 

Petroleum wasn’t particularly useful prior to World War I but by the end of it had become a pillar of national power. It fueled the motorized vehicles and airplanes that utterly transformed warfare. British Foreign Minister Lord Curzon famously said at the war’s conclusion that the Allies had “floated to victory upon a wave of oil.”

In World War II, Japan attacked the United States in part out of fear that the American oil embargo would starve its war machine, and one reason the Nazis were defeated was that they ran out of fuel. 

Of course, the strategic significance of the Middle East owed almost entirely to its vast oil reserves. The phrase “War for oil” is a cliché and usually a smear, but it is certainly true that no one has ever fought a war for wind. 

In light of all this, Europe still choose to subjugate itself to an anti-Western authoritarian, and even as Russian opera stars are getting canceled, it is hesitant to stop purchases of Russian oil and gas. 

Some perspective is called for. While climate change may indeed prove a serious long-term challenge, it is not reducing parts of European cities to rubble or a threat to use as a tactical weapon.

If this horrifying episode hasn’t scared the West straight on energy, nothing will.
