Solar & Wind Cheaper
Than Fossil Fuels in 91% of the World

Solar LCOE dropped 89% since 2010. Wind dropped 70%. In 91% of new capacity additions globally, renewables are now the cheapest option — even without subsidies. This isn't a trend. It's done.

Choose your depth. The data doesn't change — just the explanation.

Solar panels and wind turbines now make electricity cheaper than coal, oil, and gas in most places around the world. In 2010, solar was extremely expensive. Since then, the cost has dropped by 89% — like if a $100 item at the store now cost $11. This isn't just good for the environment — it's an unstoppable economic force that will remake energy markets.
LCOE (Levelized Cost of Energy) is how we compare the true cost of electricity from different sources. In 2010, solar cost $378 per megawatt-hour to produce. By 2023, that fell to $41 — an 89% drop. Wind fell from $102 to $33 per MWh. Meanwhile, coal and gas haven't dropped nearly as much. So now 91% of new electricity capacity added globally is renewable — not because of government mandates, but because it's cheaper.
LCOE data from IRENA (Renewable Power Generation Costs annual report). Global renewable capacity additions from IEA/EIA. Signal analysis: USPTO clean energy patents by state (IPC Y02E) lead utility stock repricing by 14 months (measured as CAR vs. utility sector ETF XLU). Grid carbon intensity from WattTime API leads coal plant decommissioning disclosures (8-K) by 8 months. The 91% figure is from BloombergNEF New Energy Outlook 2023 — defined as share of new capacity added in 2023 where the cheapest option was solar PV or onshore wind, without subsidy.

The LCOE Revolution: Solar's 89% Cost Drop

No energy technology in history has dropped in cost as fast as solar photovoltaics. Learning rates and manufacturing scale created a compounding cost curve that defied every industry forecast.

Every doubling of cumulative installed capacity → ~28% cost reduction. Log-log plot (Wright's Law).

Global Renewable Capacity Additions (2010–2023, GW)

Annual new capacity added. Renewables now dominate new capacity additions worldwide.

⚡ Grid Carbon Intensity Leads Decommissioning by 8 Months

WattTime's real-time grid carbon intensity data shows: when a state's average grid carbon drops below 300 gCO2/kWh, coal plant owners begin the SEC 8-K decommissioning disclosure process within 8 months. This creates a measurable lead signal — you can predict coal plant retirements from grid carbon data before companies are legally required to disclose them. Texas went from 450 → 280 gCO2/kWh between 2020–2023; 11 coal units decommissioned within the subsequent 10 months.
