Minimal Energy
Where Germany's power comes from – 50 years of the energy system in blocks.
Background
Sites, operating periods and capacities are researched from AG Energiebilanzen, the German Environment Agency, the Federal Network Agency, BASE and the operators. Grid and terrain come from OpenStreetMap and open elevation data. Every site names its source and whether the value is documented, derived or estimated.
The scenario model is deliberately simple. Ten grid regions, dispatch by cost order, base load and combined heat and power, storage with a state of charge. Power, heat and fuels stay separate. Whatever cannot be covered remains as a gap.
Two hotspots make it concrete. In the Rhineland lignite district the pit moves west, cooling towers steam according to load, and wind farms, solar fields and batteries appear on the reclaimed land. In Düsseldorf the Lausward gas plant feeds power into the grid and district heat into the city via its heat storage tank.

MINIMAL ENERGY shows where Germany's energy comes from, how it is distributed and how the system has changed since 1975. On a block map of Germany, power plants, mines, wind farms and solar fields appear, run, shut down and are dismantled. Power visibly flows through the grid corridors and across borders.
A year slider runs from 1975 to 2025. Before 1990, West Germany, East Germany and West Berlin are separate systems. Afterwards the grids grow together, nuclear power goes, wind and solar arrive.
Six controls change demand, time of day, sun, wind and season. Every change immediately becomes a marked what-if: storage charges and discharges, imports shift, bottlenecks and supply gaps become visible.

- The year slider runs from 1975 to 2025.
- Six controls: household and industrial demand, time of day, sun, wind, season.
- Views: power, heat, fuels, storage, CO₂.
- Comparison: two years, or a scenario against the starting point. The demo shows everything by itself.
