Carbon intensive fuel sources, coal and natural gas account for over 60% of the electricity available worldwide. Nuclear, hydro, wind and solar make up for cleaner power, but the process of obtaining them is too expensive for the average American. In its place, Marcus Hiles proposes smart and limited use of lights, refrigeration, entertainment and cleaning appliances. Just by switching from old, incandescent light bulbs to compact fluorescent lights can decrease up to 80% of the energy required to operate them, and new light emitting diodes (LED) work even better. Fridges and freezers can be made more effective by not adjusting them too cold, making sure they are properly sealed, are well defrosted, and situated in the coolest area possible. Televisions, computers, phones and other technology must be turned off and unplugged when not in use, as even their standby use can be major. Laundry machines and dishwashers usually have very high wattage, and their need makes it difficult to limit their use. However, decreasesin energy usage can be made by selecting the coldest temperature achievable, and by only washing full loads.
