Strong expansion with renewable energy
See the graph: With a major expansion of renewable energy (RE), a very large share—over 90 % of total consumption (blue curve)—can be supplied directly by renewables.
The graph shows three weeks of RE production in Western Denmark, with generation increased by a factor of 2.5.
To create value from the large-scale renewable energy production, industry, district heating and individual heating systems (yellow curve) consume electricity when renewable energy produces more than electricity consumption requires. When renewable energy does not deliver, power plants produce electricity for electricity consumption, and the waste steam supplies district heating plants and industrial processes.
When RE produces more than individual electric heating, district heating and industrial processes can consume, the surplus is stored in thermal batteries (green curve), and the energy is then used in the power plants when RE is not producing.
With thermal batteries that can absorb energy equivalent to 48 hours of consumption, there will only be a very limited need to stop RE production.
The thermal batteries (green curve) can produce very large effects when renewable energy produces more than can be consumed.
The total fuel consumption thus ends up being very modest, and an area's waste can – together with a strong expansion of renewable energy – largely cover the total energy demand.
Moderate expansion with renewable energy
In the existing supply areas with a significant expansion of renewable energy (Denmark, California, Germany), renewable energy should supply up to 70% of consumption with the capacity of renewable energy that is operational.
However, various conflicts driven by political framework conditions such as biogas and biomass power plants providing electricity production with subsidies, when renewable energy could supply this electricity demand - and the power plant often produces electricity because it is the waste heat from the electricity production that is needed for district heating or for process energy in industry, or energy supply that could have been supplied by renewable energy. In addition, technical barriers such as old power plants that cannot start and stop quickly cause problems with the integration of renewable energy when old plants end up producing when renewable energy could supply the electricity demand, conditions that collectively make renewable energy integration difficult.
For example, in 2024, RE in Western Denmark produced 17 TWh of electricity out of a total consumption of 24 TWh for the region. But when power plants and abroad supplied electricity to the electricity grid, when RE could actually handle the supply of the electricity grid, less than 11 TWh of the RE electricity was usable in the region, i.e. only slightly over 50% of the supply came directly from RE.
See the graph above. If RE for the Western Danish supply area could get full access to the supply without conflict with foreign electricity or electricity from power plants, then more than 75% of the electricity consumption could be supplied directly from local RE, when there is a coincidence between RE production and consumption.
When a large proportion of electricity for consumption must come from RE, it naturally follows that

The art of integrating renewable
energy (RE)
One of the most important tools for integrating very large productions from renewable energy sources is the dualistic production system, which can operate at industries. The supply network and the dualistic production system, for example, in industry consume large amounts of electricity when solar and wind produce. As renewable energy supplies fail, the power plant at the industry supplies the electricity grid and the industry switches to supplying the electricity grid.
