What's actually happening with renewables? Hype, revolution, or both?: Transition realists

The layering

In 1900, coal provided 95 percent of commercial energy. Oil was a curiosity. Then the internal combustion engine arrived. Within fifty years, oil dominated transportation. Coal was finished, right? Global coal consumption in 2023: 8.5 billion tonnes. Highest ever. More than in 1950. More than in 2010. The coal to oil transition was not a substitution. It was a layering.

We have spent careers studying how civilizations change their energy base. The answer, documented across every transition from wood to coal to oil to gas: slowly, partially, and almost never completely. The world has never voluntarily abandoned a cheap, available energy source. It has only added new ones on top.

Cost is not the only variable

The optimists have extraordinary cost curves. Solar is genuinely cheaper than coal. But cost is not the only variable, and history suggests it may not be the primary one. Coal was not cheaper than wood. Oil was not cheaper than coal. They won on density, transportability, storability. The physical foundations of industrial civilization — grids, pipelines, refineries, workforce — were built around fossil fuels over 150 years. That infrastructure has inertia measured in decades and trillions.

The deeper obstacle is political economy. Fossil fuel industries employ tens of millions, fund political parties, and operate in countries where energy revenue is the state. Saudi Arabia, Russia, the Gulf states are not countries that sell oil. They are oil states. A renewable transition threatening that revenue is not an engineering project. It is a geopolitical event.

India will matter more than any curve. 1.4 billion people, one-third of global average electricity consumption, building solar aggressively — and building new coal plants, because coal is reliable, domestic, and does not require importing lithium. The climate framing asking India to forgo cheap baseload is a request to stay poor so rich countries can meet their targets.

Where we concede ground: Solar’s cost decline genuinely has no precedent. We should hold our historical lens loosely enough to notice if it breaks.

What would change our mind: Global fossil fuel consumption declining 10 percent over five years without recession — the signature of real substitution.
