Live European wholesale (day-ahead) electricity prices and the live power-generation mix, from the Fraunhofer ISE Energy-Charts public data. Electricity is one of Europe's largest traded commodities: each bidding zone (Germany, France, the Nordics, Iberia, Italy …) clears a day-ahead auction priced in EUR/MWh, and the resulting curve drives industrial costs and energy-stock moves. The price endpoint returns a zone's day-ahead price right now plus the day's min/max/average; the prices endpoint returns the full hourly day-ahead curve; the zones endpoint lists the supported bidding zones; the power endpoint returns a country's current generation mix by source with the renewable share. Read live, nothing stored. This is Europe's own wholesale-electricity price and generation layer — distinct from fuel/metal commodity feeds and from FX or equity APIs.

Electricity cost maths as an API, computed locally and deterministically and entirely currency-agnostic. The cost endpoint works out an appliance's energy use and running cost from its power (watts or kilowatts), the hours used per day and a per-kilowatt-hour tariff — returning the kilowatt-hours and the cost per day, week, month and year, with an optional quantity of identical devices. The compare endpoint pits two appliances against each other: it computes each one's annual energy cost, the saving from the more efficient one, and — given the extra purchase price of the better model — the payback period in years and months. The convert endpoint relates watts, hours and kilowatt-hours: give any two and it returns the third, plus the cost at a tariff. Everything is computed locally and deterministically, so it is instant and private. Kilowatt-hours equal power in kilowatts times hours, and cost equals kilowatt-hours times the rate; months use 365/12 days. Ideal for energy-saving and smart-home apps, appliance comparison and retail tools, sustainability dashboards, and budgeting software. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is energy-cost maths; for battery capacity and runtime use a battery API.

Great Britain\x27s electricity grid carbon intensity as an API, from the official National Grid ESO Carbon Intensity service. Get the live national carbon intensity in grams of CO2 per kWh with its index (very low to very high), the current generation mix showing exactly how much of the grid is gas, wind, solar, nuclear, biomass, hydro, coal and imports right now (with the renewable and zero-carbon percentages worked out for you), today\x27s half-hourly intensity timeline, the carbon intensity of all 18 GB regions, the intensity and fuel mix for any UK postcode, and the gCO2/kWh emission factor of each fuel type. This is exactly the data you need to shift EV charging, heat pumps, laundry and batteries to the greenest, cheapest half-hours. Perfect for smart-home and energy apps, EV-charging schedulers, sustainability dashboards, carbon-aware computing and climate tools. Covers Great Britain. No accounts, no upstream key.

The WRI Global Power Plant Database as an API — 34,900+ power stations across 167 countries (~5,700 GW total capacity). Look up any plant by its WRI/GPPD id (e.g. WRI1000452 → Three Gorges Dam, 22,500 MW hydro); search by name, country, fuel type or capacity range; or find every power station within a radius of any coordinate (great-circle distance, optional fuel filter). Each record carries the installed capacity (MW), primary fuel (Solar, Hydro, Wind, Gas, Coal, Nuclear, …), country, latitude/longitude, commissioning year and owner. Ideal for energy dashboards, ESG/climate analytics, grid and infrastructure tools.
