It is basically an isolated heat trap for excess electricity/heat during the summer to be used during winter. It is rather like ground heat except for a few notable differences:

The cons are obvious:

• Higher investment,
• More complicated

The pros:

• Doesn’t need as much power (higher heat output during winter),
• The community has a goal of using 100% of produced electricity on site (as that is most economical), but this allow us to utilize the entire roof for solar energy, which will be more economical in autumn/spring.

Cost wise, for the tenants, it’s no difference, as the lower running costs of the battery is predicted to out weight the extra cost of capital, but in an emergency the house will be much easier to keep light and warm. The plan is to fit the house with batterier and V2G EV-chargers.

So far I’ve mostly changed how I do stuff, rather than what i do. Electric car instead of ICE Bike and train for commuting Solarpanels and 20kWh batteries for mist of my summer time energy needs.

At work I have more possibility to make a difference, though. So far I’ve had batteries introduced (solar was already norm) as an accessory to “our” buildings, I’ve gotten 2 thermal batteries (sand) built and are currently investigating building mounted small scale wind power. Among other things.

Oil dependence is use as a of controlling the world. Renewables changes that control. Therefore Renewables must be stopped.

Depends on what the alternative is. I’d prefer a beer to the water water of Flint i.e.

As bad as airing out a hot car is, it takes on a different need when its -20C and you need to thaw the car out before going to work in the morning. Much preferable to do that from inside.
