Leaving plugged-in but unused appliances (often called "energy vampires") in standby mode costs the average household roughly $100 to $200 per year. This continuous "phantom load" accounts for about 5% to 10% of your total residential electricity use.
There is the small but real risk that items left plugged in could catch fire. Most modern electrical items come with an automatic shut-off to prevent this, but it's not worth taking the chance.
Many homeowners are unaware that even when they shut off appliances, they consume energy if plugged into an outlet. This phenomenon, known as standby or vampire power, can account for a significant portion of your monthly electricity bill.

This includes both forced-air systems, heat pumps, furnaces, baseboards, window A/C units, and fans. Because they run for long periods and often at high wattage, they dominate the consumption profile.
Many folks go by the 50-50 rule. If the appliance has reached 50 percent of its expected life and it costs more than 50 percent of the cost of new, buy a new one. Oven failures can start with underperformance. For example, a family favorite just doesn't come out like it used to.

Most phone chargers draw about 0.25 watts when idle. Multiply by 24 hours a day, times 365 days a year, and that's 2278 watt-hours per year, or 2.3 kWh. At 8.2 cents per kWh, that's 19 cents a year.

Top Seven Appliances that Use the Most Energy in Your Home
According to the federal government's Energy Star program, which rates appliances based on their energy-efficiency, cooking or re-heating small portions of food in the microwave can save as much as 80 percent of the energy used to cook or warm them up in the oven.
