Renewable capacity has not kept pace with the reduction in fossil fuel capacity, creating a structural energy supply problem.

Judge as of early 2023. True if energy data show that investment in or capacity of fossil fuel supply (oil, gas, coal production or generation) fell, while renewable capacity additions were not enough to replace the lost supply, causing persistent (structural) tightness, as described by sources such as the IEA. Mostly true if the underinvestment-and-shortage picture holds but fossil capacity fell only in some regions or sectors (for example European gas, or upstream oil investment). Mixed if fossil capacity did not clearly fall overall but upstream investment fell, and the energy crunch was mainly driven by other factors such as the Russia–Ukraine war. Mostly false if the 2022 supply problem is mainly attributed to cyclical or geopolitical shocks rather than a capacity mismatch, so the claim distorts a real element. False if fossil fuel capacity did not decline and renewables additions exceeded any reductions, with no structural shortfall.

Set before the research began.

1. E1 The global energy crisis is fueling (A Call to Clean Energy: The Scramble for Energy) IMF Finance & Development, by Fatih Birol (IEA executive director) · December 2022

   “At the same time, lower investment in recent years has left some oil and gas producers unable to quickly ramp up production to meet today’s demand, even with the incentive of record high prices.”

2. E2 2022 Energy Crisis - Topics - IEA International Energy Agency

   “Many large oil producers were unable to boost supply to meet rising demand – even with the incentive of sky-high prices – because of a lack of investment in recent years.”

3. E3 From Abundance to Thirst IMF Finance & Development, by Andrea Pescatori and Martin Stuermer · 1 December 2022

   “The reduction in Russian gas flows represents a supply shock equivalent to about 17 percent of European gas consumption and non-European LNG imports combined evaporating off the market.”

4. E4 Renewable capacity statistics 2023 International Renewable Energy Agency (IRENA) · March 2023

   “2022 has seen the largest increase in renewable energy capacity to date – the world added almost 295 gigawatts (GW) of renewables, increasing the stock of renewable power by 9.6% and contributing an unprecedented 83% of global power additions”

E1 and E2 say lower investment left oil producers unable to raise supply, and E3 sizes the Russian gas cut at about 17% of European gas consumption and non-European LNG imports combined. None of the evidence says whether fossil fuel capacity fell overall, or whether the 2022 crunch was mainly driven by the war rather than underinvestment, so the criteria cannot be settled.
