That depends a LOT on its power rating, but especially on how many minutes you use it every day, on average.
Look at your toaster - electrical equipment usually has a power rating. If a power rating in watt is not given, you can multiply volts x amperes. If it says something in watts, convert that to kilowatts.
Make an estimate, how many hours you turn the toaster on in a year.
Multiply the kilowatts x the number of hours.

Since there are 6366 hours in a year, 1930 kWh is about 0.3 kW per hour. (1930 / 6366)
To calculate the energy used by a 562 W toaster operating for 13 minutes, first convert the time from minutes to hours: 13 minutes is approximately 0.2167 hours (13/60). Then, use the formula: energy (kWh) = power (kW) × time (h). Thus, energy used = 0.562 kW × 0.2167 h ≈ 0.122 kWh.
40-60 depending on what time of year it is.
The amount of KWh used by an oil boiler in a year can vary based on factors such as the efficiency of the boiler, the size of the home, and how often the boiler is used. On average, a residential oil boiler may use around 2,000 to 3,000 kWh per year for heating.
100 kWh
The amount of kWh an industry uses in a year can vary widely depending on the size of the industry, its operations, and energy efficiency measures in place. On average, an industrial facility can use anywhere from 1,000,000 to 10,000,000 kWh per year.
New energy star models are about 470 kWh per year.
a regular toaster uses about 12.5 amps
The annual kWh usage of an air source heat pump (ASHP) can vary based on factors such as size, efficiency, climate, and usage patterns. A typical ASHP for a residential home might use around 2,000-3,000 kWh per year for heating.
In ten hours, a 200W bulb will use: 10 * 200 = 2000 Watt-hours = 2 kwh
none, if it is unplugged
