Perhaps as a consumer i don't want the risk of these fluctuating prices. See what happened in Texas… That said, I do have 2kWh of battery for my balcony solar

That said, I do have 2kWh of battery for my balcony solar (it cost only a few hundred euros and prices are coming down even further), so I can spread the usage of the generated power over a longer timespan, not just during peak sunshine.
Of course, balcony solar is only for small installations. For home owners, you'll probably want something like 10+ kWp of solar panels and 10+ kWh of battery. Both of which are no longer very expensive(§). Once enough households have this, we only need those gas power stations for those rather rare periods where there is neither wind nor sun. We can also use EVs as batteries for the grid once V2G finally arrives (that's something the big utilities are stalling).

- pyrale 1y agoI am not blaming you as an agent in this system, trying to optimize your bill. You probably made the right choice for yourself. What I'm saying is that the consequence of your action will be to rise the price electricity for those without a balcony (that includes industrial users), which is a very bad systemic outcome. This outcome should have been avoided by system-wide policymaking, not by a selfless act from you. > that's something the big utilities are stalling V2G is an extremely complex thing to set up in reality, you don't need a conspiracy to explain why it's not around the corner. Just like you don't need to involve big oil to explain why fusion power is likely not happening tomorrow.
- Tepix 1y agoWhat about cheap batteries?
- pyrale 1y agoCheap anything is great. Aside from that, that would probably require a complete change in the way Germany subsidizes its energy sector, and probably harm to some private companies that benefits from these private companies. I don't really see it happening soon, but who knows?
