Undoubtedly, the biggest energy-drainer in home entertainment is the television.
Generally, TVs use 106.9 kWh of electricity per year, costing you around $16.04 annually. The best way to save on electricity costs is to use solar energy to run your TV; it can be a solar powered TV or solar generator option.
Key takeaways about powering a light bulb
On average, incandescent light bulbs use about 60 watts of electricity, and LED light bulbs use about 10 watts. Using an incandescent light bulb for 2 hours per day will use about 12.2 kilowatt-hours of electricity per month and 43.8 kilowatt-hours of electricity per year.
Heating and Cooling Systems (40%)
Heating and cooling combined use the largest amount of energy in the average Australian home. They account for around 40% of household energy use according to YourHome.gov.au.
Here's a breakdown of the biggest energy use categories in the typical home: Air conditioning and heating: 46 percent. Water heating: 14 percent. Appliances: 13 percent.
The minimum energy consumed by an electric kettle is around 1200 W, while most kettles have a maximum power rating of 3000 W. For instance, when an electric kettle works on 1200 W, it will take roughly 125 sec to boil the water. Hence, the average power consumption is 0.04 kWh.
Turning the lights off when you leave your room is necessary to help save electricity and lower your utility bills. As a homeowner, turning the lights off when you're not using them can help save money by reducing your electricity bills, extend the life of your light bulbs, and buy bulbs less often.
Turning off your lights when you aren't using them is one of the most basic steps you can take to reduce your energy usage and save money on your electricity bill. Just remember that even a small change can add up to big energy savings for you and also help reduce your carbon footprint.
CFL: If you leave 10 CFLs on for one hour per day when they're not needed, this adds an extra $6 to your lighting bills every year. LED: If you leave 10 LEDs on for one hour per day when they're not needed, this adds an extra $5 to your lighting bills every year.
Almost any type of stereo equipment you have will draw electricity for as long as it's plugged in, even when it's not in use. Microwaves and Coffee Makers. While they don't draw much, these kitchen appliances use electricity for a digital display even when not in use. Traditional Lamps.
Your fridge freezer needs to stay on all the time, so it typically uses the most electricity of all the kitchen appliances – an average of 408kWh per year.
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.
A 24-inch CRT TV consumes 75 – 95 watts of electricity per hour, while an LED TV the same size will consume roughly just a third of that energy amount. Stepping up to a 50-inch TV, a plasma-screen TV consumes 150 – 200 watts. A similarly sized LED TV uses 50 – 60 watts.
TV A typical 50 inch screen TV with a 3 star energy rating would require 147 Watts to run per hour or about 4.1 cents per hour. This equates to 24 hours of tv time. Laptop A typical laptop would require about 15 to 60 watts to run (michaelbluejay.com/electricity/ computers.
Let's say you have a 60-watt incandescent lightbulb and you are paying 12 cents per kWh of energy. Leaving the bulb on the whole day will therefore cost you: 0.06 (60 watts / 1000) kilowatts x 24 hours x 12 cents = approximately 20 cents in one day.
A new TV may use 32W to 90W of power, depending on its size. At 60W, running the TV for 12 hours a day would cost you $2.60 month if your electricity costs 12 cents per kWh.
To run a 50w halogen for 1 hour will consume 50/1000 = 0.05 kwh. At 30c/kwh this will cost 0.05 x 30 = $0.015 per hour. In comparison to run a 4.8w LED downlight for 1 hour will consume 4.8/1000 = 0.0048 kwh. At 30c/kwh this will cost 0.0048 x 30 = $0.0014 per hour.
The cost of leaving your lights on while sleeping
If you're an Australian resident, the cost of leaving each light on while sleeping is given below. Incandescent light bulbs will cost $0.068. If it stays on every night, it will cost $2.028 in 30 days.
It depends on how long and how often you are switching the lights on and off, and what kind of bulbs you are using. But in general, the cost of the electricity is a lot more than the cost of the bulb over a bulb's lifetime. So if the light will be not needed for more than a few minutes, it is worthwhile to turn it off.
How much does it cost to leave a light on for 24 hours? A LED light that remains lit for 24 hours will consume about 0.1152 kWh. If the electricity in your area costs around 0.11 per kWh, then that will add $0.012 to your electricity expenses.
On average, microwaves use about 600 to 1000 watts of electricity. Using a microwave for 15 minutes per day will use about 6.1 kilowatt-hours of electricity per month and 73 kilowatt-hours of electricity per year.
Microwaves only hold a small amount of liquid
While it is cheaper to boil large amounts of water in a microwave than a kettle, you may struggle to find a suitable container to hold the liquid.
Washing machine wattages cover a huge range, from under 300 watts per hour for the most efficient models to over 1,500 for the real energy hogs. Your washing machine's age is a big factor, because modern washing machines are overall more efficient than older models.
