In 2050, we have to go to zero consumption of fossil energy according to the Energy Agenda. That has a huge impact on all sorts of things. You need a different stove if you don't want to use gas anymore and a different central heating boiler. There are also things that you don't see at all, but are still important to know.
Electric driving is part of a larger energy transition that has been initiated in the past year. By this I mean the transition away from gas in connection with the earthquakes in Groningen. And of course the ecological burden that the use of fossil fuels entails. If you look at the total energy household of a family, then electricity is currently the largest part, followed by gas.
The moment we move away from gas, the share of electricity will only increase. And that’s before we even start talking about charging an electric vehicle. If you look at how many solar panels a family would need to be completely self-sufficient – and by that I mean both normal electricity and electricity for heating and hot water and charging an electric car – each roof would need to be equipped with around 60 panels. In most cases, this is not feasible, because there simply isn’t that much space on the roof. On average, between 6 and 10 panels can be placed on a pitched roof, so that’s a big difference from the predicted 60 that you would need for autarky (self-sufficiency).
The end of netting
I asked SolarWatt what their role is in the whole korea telegram data story of the energy transition. They see themselves mainly on the side of generation (such as solar panels) and energy storage, which should mainly cover the primary electricity need. That is life in and around the house, including heating. ( Read a more extensive article about SolarWatt and energy storage here , ed.)
When netting is discontinued – this will be the case in 2020 based on legislation introduced by former Minister of Economic Affairs Henk Kamp – returning energy will be a different story. At the moment, you return the maximum amount of energy you consume to the grid, without being deducted for it. It was to be expected that in the future there would be a difference between consumption and supply, so that there would actually be a difference between what you return and what you consume. The netting scheme was too expensive. There will now be a subsidy scheme (details not yet known) that will replace netting, which will also increase the payback period for solar panels from 5 to 7 years.
In other words: it will become easier (or at least more economical) to store capacity in solar panels, because it is simply cheaper to use your own energy than to buy energy from other parties. A business case will also be developed for a battery.
