📉 Grid parity & learning curves

Grid Parity and Beyond

Renewable energy has achieved "grid parity"—the point where it costs the same or less than fossil fuels without subsidies. In fact, we've moved far beyond parity. The International Energy Agency (IEA) declared solar "the cheapest electricity in history" in 2020, and prices have fallen further since then.

The Subsidy Myth

Critics often claim renewables only succeed due to subsidies. The reality is the opposite:

Fossil fuels receive 35x more subsidies than renewables globally^[E3]. When you include "externalized costs" (health damage, environmental cleanup, climate impacts), the true cost of coal is $0.18-0.27/kWh—far above its market price.

Energy Independence

Renewable energy provides genuine energy independence—no fuel imports, no supply chain vulnerabilities, no exposure to global commodity markets. Countries investing in renewables:

• Eliminate dependency on oil/gas imports (reducing trade deficits)
• Lock in electricity prices for 20+ years (eliminating price volatility)
• Create domestic jobs (vs sending money to OPEC)
• Reduce geopolitical vulnerability (energy can't be weaponized)

Learning Curves Continue

Unlike fossil fuels (which get more expensive as easy resources deplete), renewables get cheaper with every doubling of deployed capacity:

• Solar: 20% cost reduction per doubling (deployed capacity doubles every ~2 years)
• Wind: 15% cost reduction per doubling
• Batteries: 25% cost reduction per doubling (fastest learning curve)
