Ways to Conserve Energy
Preserve
Increase the efficiency of our fuel
Making it work better. (more bang for your buck!)
Conserve
Use less energy
Energy Efficiency
Efficiency is the percentage of energy that is actually used to perform work.
Whatever is not used to do work, is energy that is lost.
Heating & Cooling
Insulation is a layer that helps block the transfer of heat.
Keeps things warm. (like putting hot tea into a thermos)
Insulation in buildings are usually made of fiberglass.
15 cm fiberglass works as well as a 2 m brick wall.
In the Greenburg, Kansas video, they used ICF (insulated concrete forms) as a green alternative.
Lighting
If you have an incandescent light bulb, only 10% of the energy it uses becomes light.
The rest of the energy is wasted (the heat you feel)
Fluorescent Bulbs
Fluorescent bulbs use 1/4 the energy that incandescent bulbs do AND create just as much light.
Transportation Conservation
Car makers have made vehicles more efficient by creating better engines that have better milage.
Another way that we can use fuel more efficiently is to carpool and use public transportation.
