Questions about renewable energy?

Question

If someone was wanting to build a house that utilized renewable energy, why is it important that the house faces the North? What kinds of renewable energy would need the house to be facing north and why? Thanks

Answer 1

I think it means the roof should face north. That way the roof is optimumly situated for using solar panels.

Answer 2

Facing the house South or North depends upon which hemisphere you live in. In the Northern Hemisphere the Sun appears to move South in the winter, so you would want your solar panels and windows facing South to take full advantage of the sunlight. Ideally the North wall should have no windows at all (except for perhaps an artist's room) and it is even better if the entire wall is built underground.
