HW #27
Solar power1 square meter on earth gets ~ 1 kilowatt (17 light-bulbs) of energy
The sun’s energy is so strong that if only 0.1% of the earth (New Mexico + South Dakota) were covered in solar panels, we would have enough
electricity for the whole world.

HW #27
1. Passive solar energy collection
= direct absorption of sunlight.
Ex: materials chosen that absorb heat well, South-facing windows
Ex: buildings designed with windows covered in deciduous plants
