Economic growth once pulled fuel demand upward by default. Electrification, efficiency, slowing population growth, and the end of China’s first-build materials pulse are weakening that old relationship.

For most of the 20th century, a simple assumption worked well enough for energy forecasting: when economies grew, fuel demand grew with them. More people, more housing, more vehicles, more factories, more roads, more ports, more airports, more concrete, more steel, more coal, oil, and gas. The relationship was not perfect, but it was strong enough that a lot of models, policies, and investment stories absorbed it as background physics, which is precisely why it has become one of the easier ways to get the transition wrong.
Economic growth is not disappearing. People will still need heat, mobility, freight, buildings, industry, food, electricity, and infrastructure. Many parts of the world still need much more of all of them. But the machinery that used to convert growth into fossil fuel demand is changing. A forecast that starts with GDP growth and quietly turns it into rising demand for coal, oil, gas, LNG, hydrogen, ammonia, methanol, or synthetic fuels is often preserving the 20th-century system after key parts of it have already been removed.
