1. Kitchen Countertop Appliances. Get into the habit of turning off kitchen countertop appliances, such as a toaster or electric kettle, before heading to bed.
Unplugging your TV every night generally provides minimal energy savings ($1–$30/year) and is unnecessary for modern sets. While it protects against power surges and reduces "vampire" standby power, it can prevent OLED TVs from running crucial maintenance, potentially causing damage, and can stress internal components.
Is switching off a socket the same as unplugging? The only method to ensure no electricity flows through an appliance is to turn it off at the socket and pull the plug out.
Gregor recommends unplugging microwaves, coffee makers, toasters, blenders, food processors, kettles, slow cookers, rice cookers, and ice makers — pretty much any small kitchen appliance.

Ranges, stoves, and ovens are the appliances most likely to cause house fires. They account for the largest percentage of home appliance fires—primarily because they involve high, open heat sources and are frequently left unattended.
Electric heating systems and tumble dryers tend to be the most expensive electrical items to run because they use large amounts of power over extended periods. Other high-cost appliances include electric ovens and immersion heaters.
Leaving the TV on all night does not consume a massive amount of electricity, but it adds up over time. An average 55-inch LED/LCD TV draws about $0.05 to $0.15 per night, translating to roughly $𝟏𝟓 to $𝟓𝟎 per year in wasted energy.
Make sure you turn off at the wall for appliances such as your TV, computer, game console and phone charger. When devices are left switched on, even on stand-by, they are still consuming (and wasting) energy. If you can't switch off your wall plug, unplug the device once it's fully charged or no longer in use.
Sony generally ranks as the most reliable TV brand for overall longevity. They feature better build quality, premium thermal designs, and fewer motherboard and power-board failures. LG and Panasonic follow closely, particularly LG for OLED displays and Panasonic for standard LED lifespan.
It is possible, but usually only if your TV has a built-in camera and is connected to the internet. However, smart TVs don't actually need to watch you to track your habits. Instead, they use background technologies to monitor and sell your viewing data to advertisers.

Heating and cooling (HVAC systems)
Heating and air conditioning are the largest sources of residential electricity use in most climates. According to the U.S. Energy Information Administration, space heating and cooling together account for more than 50% of a home's annual energy consumption.
The fix: Lower your home temperature to 68 degrees when you're home. Maintain comfort by adding extra layers of clothing – try fabrics like fleece, flannel and wool – and don't forget comfy slippers and blankets.
