The claim that renewables are cheaper relies on a metric called the Levelized Cost of Energy (LCOE), which measures the cost of generating a unit of electricity. By this narrow measure, wind and solar have become impressively competitive. But LCOE doesn't tell the full story — not even close.

The sun doesn't always shine and the wind doesn't always blow. When you add the costs of intermittency — backup power for when renewables aren't producing, battery storage, grid upgrades, and transmission infrastructure — the total system cost is dramatically higher than the generation cost alone.

Germany is the clearest real-world example. After spending over $500 billion on its Energiewende renewable transition, German residential electricity prices reached approximately 40 cents per kilowatt-hour — roughly three times the U.S. average. German industrial electricity costs are among the highest in Europe, driving energy-intensive manufacturing to other countries.

Renewable energy in the U.S. receives over $30 billion annually in federal subsidies, tax credits, and mandates, according to the EIA. If solar and wind were truly cheaper, these wouldn't be necessary. No one subsidizes cheap things.

Land use is another overlooked factor. A nuclear plant producing 1 GW of reliable power needs about one square mile. To produce the same energy with solar, you'd need approximately 75 square miles. With wind, about 360 square miles. Scaling renewables to replace fossil fuels would require converting enormous areas of land or sea.

The most effective low-carbon energy source is nuclear power, which provides reliable 24/7 electricity with minimal emissions and tiny land requirements. France generates about 70% of its electricity from nuclear and has some of Europe's lowest electricity prices and emissions. That's the model to follow — not Germany's expensive experiment.

I support developing renewables as part of the energy mix. But pretending they're a complete replacement ready to deploy today is fantasy, not policy.
