Energy and Climate
🌱 Energy, Climate and the Ecological Transition
In 2025, renewables generated 55.5% of Spain's electricity, according to Red Eléctrica. This section presents the official figures for the electricity system, greenhouse gas emissions and the growth of installed renewable capacity.

How the National Electricity Mix Has Changed
The Spanish electricity system has undergone a historic transformation: between 2007 and 2025, wind and solar PV have gone from 9.9% to 40% of total generation, while coal has fallen from 24.8% to 0.6%.
Renewable and Emission-Free Share
Greenhouse Gas Emissions by Sector
Transport is the sector most resistant to decarbonisation: it accounts for 33.8% of emissions in 2024. Electricity generation, by contrast, has cut its emissions by 60% since 1990 thanks to the roll-out of renewables.
Detailed Reports
Electricity Generation Mix
An in-depth look at the electricity mix: the rise of wind and solar PV, the phase-out of coal, the reliance on natural gas and the role of nuclear power.
Emissions and Decarbonisation
Greenhouse gases broken down by sector: why transport is the big outstanding challenge and how electricity is already decarbonising.
Water Reserves and Reservoirs
The weekly state of reservoirs by river basin: how much water there is, and how it compares with last year and with the average for the past decade.
Heat and Temperatures
The daily heat map by province: how far the maximum temperature departs from each day's historical average, the records and the trend since 1991.
Wildfires
Hectares burnt each year since 2000, how much burns within the Natura 2000 network, a map of this year's fires and active fires detected by satellite.
The Electricity System, Right Now
Live every 5 minutes: demand, renewable % and CO₂ intensity for Spain, the Peninsula, the Balearic Islands, the Canary Islands, Ceuta and Melilla, exchanges with neighbouring countries and the electricity price.
Electricity System Records
All-time highs and lows since 2015 from REE's 5-minute data: demand, solar, wind, renewable share, emissions, prices and exchanges, and when each record was broken.
Power Plants
A map of every power plant in Spain by technology and capacity: those in operation, those under construction or in the permitting process and those already closed, with their owner and key dates.
Storage
Pumped hydro and batteries: how much energy they store and return, where they are, and the projects with grid connection permits compared with the 2030 target.
Electrification
How much of the energy used by industry, transport, households and services is already electricity, how homes are heated in each province and how many heat pumps there are.
Methodology and Primary Sources
| Body | Dataset | Code | Licence |
|---|---|---|---|
| Red Eléctrica de España (REE) | Annual generation and demand (REData API) | REE-MIX | Open Data / RISP |
| MITECO / Eurostat | National GHG Emissions Inventory (env_air_gge) | MITECO-GEI · Eurostat | RISP (Law 37/2007) / CC BY 4.0 |

Electricity generation data come from the national balance measured at power plant busbars by REE as System Operator (full years only). Emissions are those of Spain's official inventory (excluding LULUCF), calculated according to IPCC guidelines and reported to the United Nations Framework Convention on Climate Change (UNFCCC); Eurostat publishes them broken down by CRF category, which are grouped into sectors here.
