SOLAR ENERGY AND PASSIVE SOLAR HEATING

Chris mccainWayne biddy

• The sun is a medium sized star that radiates energy from nuclear fusion reactions in its core.• The small fraction of energy from the sun

is enough power the wind, plant growth, and the water cycle.• All the renewable energy comes directly

or indirectly from the sun.• We use direct solar energy everyday.• When the sun shines in your window and

heats up your room by solar power.• Passive solar heating uses the sun energy

to heat something directly.

• The south facing windows receives the most solar energy, so passive solar building have large windows that face the south.• Passive solar buildings must be well

insulated win thick walls and floors in order to prevent heat loss• In the summer the sun’s path is high in

the sky ant the overhang of the roof shades the building and keep it cool• In the winter she sun’s path is lower in the

sky and the sunshine in your house which warms it• A average house hold can reduce energy

bills by using passive solar energy
