Your kid gets profiled online before they can spell 'privacy.'

We're aiming to change that with #BornPrivate.

Some insights I gained from writing and testing Sonnenwende.

1. Solar panels have become so cheap that electricity becomes worthless when the sun is shining. Hence, any government initiative giving guaranteed prices to solar power is mostly a waste of money better spent elsewhere.

2. This has the counterintuitive effect that a solar park owner will hope for cloudy weather, as clouds act as an involuntary cartel bringing prices up.

3. The hard part is having enough battery power during nights, especially in winter when the short days make it very challenging to charge your batteries.

4. Towards the end of the game, making money conflicts with reducing the share of fossil power, as the latter sets the electricity price. A successful transition to renewable energy production will likely require the implementation of different pricing mechanisms. If you have any (preferably peer-reviewed) ideas how this could work, I'd be happy to add them as an alternative scenario.

5. Hydrogen storage appears to lose out against battery storage when all costs are considered. Storing energy is cheaper for hydrogen, but hydrogen power is much more expensive per kW. This means hydrogen does not look like a cost-effective route towards renewable energy production (sorry, @bmftr_bund).

I wrote a small game simulating the transition to a solar-powered economy. You can build solar panels, batteries, hydrogen storage and sell your generated electricity at market prices. Electricity demand, pricing, and weather conditions are based on realistic models for Germany.

This is fun - a daily quiz where you have to guess the animal in 20 guesses, with wrong guesses giving you information about taxonomy.
