Safety first The U.S. Consumer Product Safety Commission recommends unplugging electrical devices when not in use, predicated on the obvious but nevertheless correct observation that something unplugged can't start fires or shock someone.
Unplugging appliances that you're not using can help to conserve energy and reduce your carbon footprint. When electrical appliances are left plugged in they can still use a small amount of power, even when they're turned off.
Many appliances continue to use electricity even when they are shut off. The same goes for all those chargers, whether or not they are charging a smartphone. Everything you leave plugged into an outlet—appliances, computers, consoles, chargers, lamps, and more —draws energy even when not in use.

Ideally, an unplugged refrigerator can keep the insides cool for around 4-5 hours. Beyond that, the temperatures start going up. If you are unplugging the fridge for more than three hours, then you will need a cooler and ice packs to keep the food items cool.
Coffee makers. Television sets. Washing machines. Practically every appliance and electronic device you have plugged in at home is using some electricity — and adding to your utility bill — even when it isn't in use or even turned on.
If you're wondering, “How much power does a TV use?” there are a number of factors to consider. The average TV watts are 58.6 watts when switched on and just 1.3 watts in standby mode. Understandably, there's a big difference between what TVs consume per year.
If the wall socket doesn't have an on off switch it would need to be unplugged instead. Electricity still runs inside an appliance even if it's switched off. If electricity is present, there is always the possibility of something overheating or shorting out.
Although a kettle is not the worst energy consumer, switching it off at the wall can make a surprising saving. The expert noted: “Leaving an average kettle plugged in and switched on when not in use uses around 0.3kWh.

If you leave your computer or laptop plugged in to charge overnight, you could be wasting a significant chunk of electricity. Even when it's off, that power cord will continue to draw energy. Phones. Similarly, leaving your phone plugged in to charge overnight is a bad idea.
Switching off your TV when not in use will do more to reduce energy usage than anything else. Manufacturers have improved standby efficiency - in most new TVs energy usage is typically below 1 watt - so this is an option if you have a new TV, but if you have an older model, this mode may be using energy unnecessarily.
If the food warms up, the bacteria will reach harmful levels faster.” For this reason, the USDA recommends that food left in an unplugged, unopened fridge for more than four hours be tossed. (Frozen items left in a full freezer stay good for two days; in a half full freezer it's more like 24 hours.)
Store your fridge upright to avoid damage to the inside mechanisms and sealed systems. Keep the door open or ajar to prevent odours and moisture build-up. Don't place anything between the door and the fridge to keep it open if it pushes against the seal – this can damage the seal.
