Reply to 'Houses That Can Save the World': These homes offer a blueprint for a greener future by _613_
Every new building in EU must now comply to Near Zero Energy standard. We can NOW build houses that are green.
If you get a big garden, you can even feed yourself. And it doesn't have to look like a tray of eggs.

Reply to comment by Truth_is_Liberal in Egypt to add 1.1 GW in solar, wind power with cheapest rates in Africa by darth_nadoma
Last week europe hit some highest electricity spot prices partly because there was no sun and no wind for few days. What would you suggest we do on these days in winter?

Just an electrical correction.
Combined voltage in 3 phased circuit for 230V phase voltage is 400V. For old 220V circuits it's 380V. 360V never existed.
Current in 3 phase circuit can't be just added together when using combined voltage.
However, with resistive AND balanced load (implying perfect 3 phase kettle), you can just calculate single phase current and divide by 3. So the current for 67.2kW in 3 phase circuit would be ~97A per phase.
