Has anyone here already looked into the coalition agreement presented today and its implications for (us) homebuilders?
A positive point for new homeowners could be that there will be an exemption for property transfer tax if the property will be owner-occupied. The rent control measures are planned to be extended. There is a goal to build 400,000 new homes, of which 100,000 will be publicly subsidized.
As the operator of a gas condensing boiler, I would have been very interested to know whether Nord Stream 2 will become operational or not, but I haven’t read anything about that. Natural gas-generated electricity is supposed to be phased out by 2040, whatever “phased out” actually means. In the mid-2030s, natural gas heating systems are expected to be discontinued.

no suggestion for a technical solution Technical solutions do exist, some for decades. However, politics and society alone have not managed to use the already available and applicable technologies effectively and sustainably within a holistic concept. The reasons are complex: lobbying, bureaucratic obstacles, and sometimes very vocal representation of minority interests, especially through citizen initiatives. The current grid structure and management—which is still fully designed for centralized energy supply and distribution—do not truly allow for decentralization.

This can be designed to support the grid if the charging and discharging behavior of individual EVs is not left to each user alone, but coordinated at the grid operator level. BMW had a pilot project in California with the i3 (which has been bidirectional from the start, for over 10 years now), where the wallbox—controlled by the grid operator—could feed energy back to the grid or draw from it. The requirement, however, was that the car must be given minute-by-minute instructions on where it will be driven, so that the corresponding state of charge (SoC) is prepared. Unfortunately, this is quite inflexible for the driver. This provides a certain time-based balance between peak loads and peak generation. From a grid technology perspective, the use of power electronics can cause quite nasty harmonic oscillations and potentially damage connected equipment or cause outages. In solar power generation, the behavior of photovoltaic systems can be predicted fairly well based on weather data. With millions of car batteries, which primarily serve a different purpose and can be fed into the grid without warning, I’m curious to see how that will work out.

The idea is precisely about making effective use of pooling by employing electric vehicles as load balancers. Currently, renewable energy is taken off the grid so that polluting power plants can continue running at a base load. Instead of shutting down wind turbines or converting excess energy into heat through ground probes (which sounds odd and is indeed inefficient), a swarm storage system can help reduce the base load of these polluting plants and increase the utilization of renewable energy from existing wind and solar installations. The fact that this swarm storage is mobile, serves as a functional object in every household, and is privately funded works only in favor of quick adoption.
I find this quite logical and positive—acknowledging that this is not a solution meant to last 30 years from now since mobility itself needs to be rethought—and recognizing that there are indeed questions around the sustainability and efficiency of current batteries.
The subsidies aim to "exploit" people’s greed so that purposeful, climate-friendly actions become more widespread. Unfortunately, our brains tend to switch off when doing the right thing seems too expensive.
Certainly, two people who think carefully can arrive at different assessments and solutions. Accusing each other of stupidity gets us nowhere. But wouldn’t it be more sensible to store unused energy in stationary home storage instead? That way, I could produce and save energy during the day and use it during peak times exactly when it is needed. With storage in vehicles, there is always the problem mentioned: you might be at work all day and cannot charge the car there because the employer has no solar power or does not permit private use... Or perhaps the wife wants to run the washing machine during peak load times while the husband is still at work.

If you consider both at the same time, this question becomes irrelevant. If batteries are purchased anyway due to changes in the vehicle fleet, their function as home storage can be regarded as a collateral benefit.

The load and oscillation behavior of charging and discharging electronics is an interesting topic and, in principle, quite well manageable.

Bertram10028 Nov 2021 10:54I can report that I am sufficiently equipped with photovoltaic panels (5.5 kWp) and a home battery (10 kWh), and both are quite ineffective in winter. Generating and storing enough energy in an environmentally friendly way is not so easy on a very small scale at the level of private households.
