Electricity Maps vs Energy Charts
A side-by-side look at the Electricity Maps and Energy Charts MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Electricity Maps for environment & nature work as a local process; choose Energy Charts for environment & nature as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Electricity Maps when
- You need dedicated capabilities in the Environment & Nature domain.
- You prefer a local stdio subprocess transport.
- You want tools like
electricitymaps_carbon_intensity, electricitymaps_power_breakdown, electricitymaps_carbon_forecast.
Choose Energy Charts when
- You need dedicated capabilities in the Environment & Nature domain.
- You prefer a local stdio subprocess transport.
- You want tools like
generation_mix, public_power, electricity_price.

Tools & capabilities
Electricity Maps tools 3
electricitymaps_carbon_intensityCarbon intensity (gCO2/kWh) for a grid zone now — the live climate cost of a kWh drawn from the local grid. Pass a zone code (e.g. "US-CAL-CISO", "DE", "FR", "GB") or lat+lon. Example: electricitymaps_carbon_intensity({ zone: "DE", _apiKey: "your-key" })electricitymaps_power_breakdownPower generation mix for a zone — the latest breakdown of electricity by source (nuclear, wind, solar, hydro, coal, gas, ...) plus fossil-free and renewable percentages. Pass a zone code (e.g. "US-CAL-CISO", "DE", "FR", "GB") or lat+lon. Example: electricitymaps_power_breakdown({ zone: "FR", _apiKey: "your-key" })electricitymaps_carbon_forecastCarbon-intensity forecast for a zone — upcoming hourly gCO2/kWh predictions, useful for scheduling loads when the grid is cleanest. Requires a paid Electricity Maps plan. Pass a zone code (e.g. "US-CAL-CISO", "DE", "FR", "GB"). Example: electricitymaps_carbon_forecast({ zone: "GB", _apiKey: "your-key" })

generation_mixThe CURRENT ELECTRICITY GENERATION MIX BY FUEL for a European country — how much power is coming from solar, wind, nuclear, gas, coal, hydro, biomass right now, with each fuel's MW and percentage share. Answers "what is Germany's generation mix", "how much of France's electricity is nuclear", "Germ…public_powerElectricity generation broken down by production type (solar, wind, nuclear, gas, etc.) for a country over a date range. Returns {unix_seconds, production_types:[{name, data}]}; each series' data array is timestamp-aligned to unix_seconds. Power in MW.electricity_priceDay-ahead spot electricity prices for a bidding zone over a date range. Returns {unix_seconds, price, unit}; the price array is timestamp-aligned to unix_seconds. Prices in EUR/MWh.total_powerTotal electricity generation / load for a country over a date range. Returns {unix_seconds, production_types:[{name, data}]}; data arrays are timestamp-aligned to unix_seconds. Power in MW.installed_powerInstalled generation capacity by production type for a country, as an annual or monthly series. Returns {time:["2002",...], production_types:[{name, data}]}; data arrays are aligned to the time array. Capacity in GW.renewable_shareRenewable share of a country's electricity LOAD, as a percent — how much of demand wind, solar, hydro and biomass are covering, now or over a past date range.

Frequently asked questions
Electricity Maps is categorized under Environment & Nature and uses a local stdio subprocess. Energy Charts belongs to Environment & Nature and uses a local stdio subprocess. Pick Electricity Maps for environment & nature work and Energy Charts for environment & nature.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Electricity Maps has no declared pricing — check the project's own site. Energy Charts has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add electricity-maps and energy-charts as separate keys in the same mcpServers object, and your assistant will call tools from either one.
On AllMCPs, Electricity Maps has a quality signal of 59/100 (Good) with 2 views, 0 installs and 0 GitHub stars. Energy Charts has 55/100 (Good) with 1 views, 0 installs and 0 GitHub stars.
