TVs represent for a modest portion of the energy consumption pie when compared to other gadgets and appliances in the average home. Most current TVs utilize less than 250 watts, which equates to a few bucks per month for even the most devoted couch potatoes. However, some high-definition (HD) models can draw up to 75 watts, so be sure to check the wattage before you buy.
The majority of the power used by a television is actually consumed by its component parts: the screen, the speaker system, the remote control unit, and any ancillary equipment needed for sound and video processing. The rest of the energy intake comes from fossil fuels, mainly oil and natural gas. The amount of energy used by a television is relatively small compared to other household appliances, but it does contribute significantly to the total energy usage of a typical house. For example, a TV that's on all day long uses about as much energy as several space heaters or one hot water heater.
In conclusion, a television consumes little energy overall, but it does play a part in consuming some energy every time you turn it on. In fact, according to the U.S. Department of Energy, televisions are one of the most energy-hungry devices in the average home. In addition, they emit harmful gases such as mercury vapor and lead carbonate into the atmosphere.
Although a larger television requires more energy to power, a large energy-efficient television can consume less energy and cost less to run than a smaller, less efficient one. It's worth noting that, while TVs account for half of all consumer electronics power usage, consumer electronics account for only 4% of all household electronics. The other 96% of devices in the home require electricity too.
Televisions use more energy than most other consumer products because they are always on. Even when they are not being used, they still emit light so they must be plugged in to power their lamps. This means that televisions are by far the biggest user of energy by any consumer product.
Additionally, they are very heavy so they need an outlet to plug into. Placing them in storage is also inefficient because they will continue to draw power even if they are turned off. Finally, they contain many parts that leak electrical charge, such as cathode ray tubes (CRTs), which are very sensitive to damage from static discharge. Static shock can cause them to break down internally.
The best way to conserve energy is to use less product. That means turning off TV sets when they are not being watched, and using energy-saving settings on your television set-top box or cable provider service.
In conclusion, because TVs are always on and heavy, they are by far the biggest user of energy by any consumer product.
Using our 200-watt TV as an example and the EnergyGuide benchmark of 11 cents per kWh, using the TV for 12 hours per day would cost $96.36 per year. Of course, the amount of electricity used by a television depends on a variety of factors, including: Age: Older devices may demand 400 watts or more, more than tripling the expense of our previous example. Size: A larger television will use more power. Form factor: A floor model uses less energy than a comparable size LCD television.
In addition to being expensive, using your television constantly for this length of time could be bad for the environment. The key word here is "constantly." If you use it only at night, when the solar panels are generating most power, it would be better for the environment. However, because most households have lighting et al that are on even when they're not used, their energy consumption is higher than what it would be if they were turned off at night.
The average household in the United States uses about 15% more electricity during summer months due to air conditioning. This represents a huge increase in energy usage that leads to higher costs and pollution. It's best to avoid using air conditioners all together during the hot months unless you need to protect someone from the heat or not be able to sleep because of too high a temperature. There are many other ways to cool down without using electricity that don't put our environment at risk.
That's still much more than the 21% accounted for by our home computing systems, suggesting that addressing energy efficiency while purchasing a new TV is still a good idea. The typical new 40-year-old "Every year, it costs roughly PS28 to run a television. A+ certified energy-efficient 40 "Every year, it costs PS8 to run a television. A+ certified energy-efficient 40 inch LED display or smaller. That's about half the cost of keeping up with technology trends and buying an energy-efficient TV.
Here are some other tips on how to save money while cutting down on your carbon footprint:
One way people can reduce their energy bills is by installing insulation. Insulation reduces the amount of heat that escapes from one room into another, so heating and cooling one area does not have to be as intense. Insulating your home can also help prevent damage caused by cold weather and hot temperatures. The National Institute of Standards and Technology estimates that insulating homes against temperature extremes could reduce fuel usage by 15 to 20 percent.
If you want to cut down on your energy bill even more, consider replacing your old windows with insulated ones. Old windows don't limit light and heat inside your home, so they allow more sunlight in during the day and heat in at night. This excess heat causes air conditioning needs to remain on all night long, which is why so many people think their homes are hotter when they aren't using as much energy.
Most televisions consume between 80 and 400 watts, depending on size and technology. Using an example cost of 15 cents per kilowatt-hour and five hours of watching every day, the monthly cost ranges from $1.83 to $9.13. Energy Star recommends that you switch off appliances when they are not in use.
