A live, daily test of carbon-aware electricity pricing — and the CO₂ it would save — across Switzerland and the US grid.
What if electricity got cheaper when the grid runs clean and pricier when it runs dirty? Every day this site runs that idea on real electricity-grid data and measures how much CO₂ it would save compared with today's standard pricing — across Switzerland and US grid regions.
Standard Today's fixed tariff — the baseline everything is compared against.
Carbon-Aware Hourly The price follows the grid's carbon level, hour by hour.
Carbon Peak Pricing Normal price, plus a sharp spike in the few dirtiest hours.
