| Renewable power capacityRenewable power capacity Installed capacity of solar, onshore wind, biomass and hydro power in operation per resident, where the units stand. Capacity, not generation: a kilowatt of wind yields about twice as much electricity in a year as a kilowatt of solar. Over time: the units in operation at the end of each year, per resident of 2023. Wind turbines taken down before the register began (2019) are often missing: the early years are too low, before 2010 markedly. 2026 | 3.01 kW p.c. | 1.94 kW p.c. | 2.57 kW p.c. | |
| Solar powerSolar power Installed solar capacity in operation (peak power of the modules) per resident, wherever it stands: rooftops and solar parks. Over time: the units in operation at the end of each year, per resident of 2023. 2026 | 2.46 kW p.c. | 1.47 kW p.c. | 1.56 kW p.c. | |
| Wind powerWind power Installed onshore wind capacity in operation per resident, where the turbines stand. Offshore wind farms belong to no area on the map. Over time: the units in operation at the end of each year, per resident of 2023. The register began in 2019: turbines taken down before then are often missing, so the early years are too low (2000: about half of the wind capacity of the time, 2010: nine tenths; from 2015 nearly all). 2026 | 0.48 kW p.c. | 0.37 kW p.c. | 0.85 kW p.c. | |
| Biomass powerBiomass power Installed electrical capacity of biomass and biogas plants in operation per resident, where they stand. Over time: the units in operation at the end of each year, per resident of 2023. 2026 | 0.06 kW p.c. | 0.07 kW p.c. | 0.11 kW p.c. | |
| Balcony solar unitsBalcony solar units Plug-in solar units (balcony power plants) in the Marktstammdatenregister per 1,000 residents. They must be registered, but many are not: the real number is higher. Over time: the units in operation at the end of each year, per 1,000 residents of 2023. 2026 | 25.3/1,000 | 19.6/1,000 | 18.2/1,000 | |
| Battery storageBattery storage Usable capacity of battery storage in operation per resident, home batteries and large grid batteries alike: a single large battery can dominate a rural area.

| Land take for settlement & transportLand take for settlement & transport Settlement and transport area added per year from 2019 to 2023, per resident. Ground-mounted solar parks count as settlement area, so new solar parks raise the value. When a Land reclassifies its land register, areas can seem to shrink (Hessen 2022). Earlier years are left out: the switch to a new register made areas jump. 2023 | 4.3 m² p.c./yr | 4.4 m² p.c./yr | 2.4 m² p.c./yr | |
| Household wasteHousehold waste Household waste collected by the public services in 2024, per resident: residual and bulky waste, organic waste and separately collected recyclables. 2024 | 397 kg p.c. | 398 kg p.c. | 452 kg p.c. | |
