⚡ Solar is now the cheapest electricity in history

The IEA declared solar the cheapest source of new electricity generation globally. In many regions, building new solar is cheaper than running existing coal or gas plants — a remarkable turnaround from just 15 years ago.

A typical 6 kW residential system produces around 7,000–10,000 kWh/year depending on location and sunlight — enough to cover most of an average home's electricity needs — while offsetting roughly 2-4 tonnes of CO₂ annually.
