Comment: Re:Space for solar hasn't been much of a concern (Score 1) 437

Solar panels work just fine in ambient light and will produce significant energy in the fog or on overcast days. Sure, you'll lose some, maybe upto as much as 50% efficiency in really overcast days, you'll just have to get a bigger battery to reduce the "range anxiety" type issue. Solar panels are actually more efficient at cooler temperatures than hot ones. Germany leads the world in residential solar right now, and doesn’t have a sunny climate.

If people insulated their houses to a high level like PassivHaus, they will find that they are far less reliant on heating/cooling systems because the insulation keeps the house at stable temperatures

Promising costs nothing, it's the delivering that kills you.
