While I don't necessarily agree with the use of the term 'hog' here, it is necessary to illustrate the miscellaneous energy loads (MELs) in your home. These are the electrical appliances that use up way more than their fair share of energy.
I read the article and it surprises me that fan is one of the identified energy hogs. I thought leaving 10 fans switched on the whole day uses less energy than turning a single 2.5HP air-conditioner on for 8 hours.
Surprising 8 energy hogs
GreenTech Media reported a finding by American Council for an Energy-Efficient Economy, which listed the following eight technologies in the home that are due for an energy efficiency makeover:-
Televisions. Even though your television has gotten slimmer, it is a growing part of energy use in your house. More than half of homes have at least three televisions. New TVs, such as LCD and LED models, are more efficient, but they are also usually larger, which offsets efficiency gains.
Set-top boxes for cable or satellite TV service. The energy use continues to climb with the popularity of DVRs, which require the box to be active for more times of the day.
Personal computers. More efficient active and sleep modes as part of Energy Star standards have made some gains, but increasing numbers of laptops and tablets mean that many of us are more plugged in more often.
Video game consoles. Like personal computers, video game consoles have gotten more efficient over the years, but they have also gained in popularity and are used for a lot more, and many are left on all the time.
Ceiling fans. Overall ceiling fan energy use is going up and is expected to increase through 2030. ACEEE estimates savings of 84% are possible if current fans were all replaced with the best available technology.
Microwaves. Even if you only use the microwave for popcorn, it can still suck up a lot of energy in standby mode.
Monitors. Standalone computer monitors have gotten more efficient in recent years, but usage has outstripped the gains. Since 2006, computer monitor usage has increased about 35%.
Cordless phones. This includes all rechargeable electronics -- including everything from cordless and cellular phones to electric toothbrushes and power tools. The cordless phone continues to be responsible for about half the energy consumption amongst rechargeable electronics in homes.
