From 24-electricity to 24×365 electricity






How to refine 24-electricity to 24×365 electricity? There had been the sun-wind theory for three decades: the sun delivers more in the summer, and wind delivers more in the winter. This would require, on average, in Europe, 2 kW wind systems for every kW photovoltaic. Just right now in Germany, 0.72 kW wind for 1 kW photovoltaic, and the gap widens fast: 0.24 in Germany, 0.2 in the EU and worldwide at new installations in 2024 and 2025. From 24-electricity to 24×365 electricity The next border is at 300 GW photovoltaic and 750 GWh batteries: some sunny summer days, and all Germany is 100% solar-electric all this time. The required ratio according to the 'sun shines more in summer, wind blows more in winter' theory vs. reality. The next theory was biomass for the winter gap: not enough sun, not enough wind; we would start power plants fueled by biomass.. Extremely inefficient land usage. The first border for photovoltaics in Germany was 70 GW: we cannot switch off more caloric power plants than we have running. The next border is at 300 GW photovoltaic and 750 GWh batteries: some sunny summer days, and all Germany is 100% solar-electric all this time. What to do beyond this next border? Just waste abundant production? Install more batteries? Use it for power to X?

  Cost optimization — the key to energy transition and climate protection
Paper written for the CORP.at conference March 22 to 25, 2026, in Vienna. My 2025 participation was a last-minute action, but now I have much time to prepare the paper.

Abstract
To meet the necessary cost optimization targets, we cannot hold the energy problem separate from all other problems: another major problem is housing.
Introduction
Many imaginations about our future had been created in the past with completely different parameters. Unchecked conclusions from the past endanger our future with unbearable costs.
My personal experience with a profitability transition My personal experience with a profitability transition
Birds can fly without knowing all the terms of aerodynamics. I reacted with my design change to an ongoing “profitability transition” without knowing the term at this time.
Energy transition
The long way from random electricity from sun and wind towards 24×365 electricity. Overseen profitability transitions have to be considered as major accidents.
Solar yield and conversion to 24×365 electricity
The wide range of solar yield becomes much wider after the conversion of gross yield to 24×365 electricity. 6 examples from our research of 50 locations.
The GEMINI principle: double usage of land
No better solar power plant, no better housing possible on the same ground is the ultimate target of the GEMINI principle.
Off-grid fast charging settlements Off-grid fast charging settlements
It can start small, somewhere in a village, with a single GEMINI house with a big PV carport and 100 kW DC charging.
Energy-intensive industry
I once developed a scale for off-grid solar possibilities depending on photovoltaic size. But now is to make a big jump upwards on this scale: running, energy-intensive industry.
Agriculture: How many square meters does a human need for his food? Agriculture: How many square meters does a human need for his food?
Mankind started as hunters and gatherers. 12,000 years ago, 500,000 m² to 2,500,000 m² per human. With the agricultural revolution, the land use was reduced by 2 magnitudes.
Conclusion
All parameters are in a constant state of change. We have to check all the parameters and predict the development for the predictable future.
