led tv electricity usage image

I'm doing a project on this but I can't really find much information on the amount of energy that is used up. Does anyone know?
The amount of energy used for lighting up a building at night would be useful too.
Answer
The numbers you seek are all relative....
Let us say that a marque has 500 small light bulbs and that each light bulb is a 25 watt light bulb. This means that each bulb uses 25 watts per hour. Lighting up the marque for one hour then uses (500*25w) or 12,500 watts. If the marque is lit for 10 hours per night, then the amount of energy used just on the marque climbs to 125,000 watts for just one night; and 54,125,000 watts in a single year of 365 nights. This does not include the building, accent, doorway, or spot lights used on and about the building.
The amount of energy used for any one light show, on any one building, etc,,, depends upon the sum of the wattage of the light sources times the amount of time they are used.
Getting back to the marque example, some businesses are moving towards LED lights which use far less energy for the amount of light, or lumens, they give off. Other businesses are moving towards an assortment of timers and photo-electric cells to guide the turning on and off of their lights.
Home owners and apartment dwellers can do the same. They can also use a number of different types of CFL light bulbs which use far less energy than incandescent light bulbs to produce the same number of lumens, or amount of brightness. Towards "decorative" lights, many people are shifting to strings of LED Christmas lights, LED rope lights, and LED decorations; both for use at Christmas and on the patio in summer. Those that make these changes in a short period of time, often report that they can notice the difference on their power bill; this is an indicator that the actual power usage savings is great enough that they can readily notice it.
When considering the amount of energy used to light up a marque and then the potential energy use savings by switching that marque to an LED system, the numbers are bigger and more satisfying than the numbers in a single family residence due to the sheer number of light bulbs involved. But, as a number of different, individual residences all switch to energy saving CFLs, LEDs, solar lights, and take up additional power savings activities the savings can be tremendous. For example, within the past two years the State of California determined that 10% of all of their electricity usage is being utilized by TVs; both business and personal. Sure, a number of those TVs are probably located in bars, taverns, lobbies, and clubs. But, my guess is that a far larger percentage of them are in private residences.
There is a lot of collective energy savings potential within private residences. On the other hand, baseball fields that are brighter at night than during the day, large marques, and places like the Vegas Strip do make one ask about energy consumption.

how to power a remote cabin with no wiring by means of wind turbine only?
Q. there are no transmission lines in the vicinity so power can't be brought in, and even if it did it would be far too expensive. So how wind in conjuction with solar power the cabin? is that even possible?
Answer
Hey Timewaster, we live in a solar and wind powered cabin now, so yes, it's possible. When you say remote cabin, it's a little like asking, "How much gas does a car use?" Your answer would start hitting on subjects like miles per gallon, total miles, vehicle weight, and stuff that a non car driver would not understand. A remote cabin might have a few lights, or a deep freezer, the difference in power needs is very dramatic, even if the two cabins were the same size. So usage is very key, but not easy to determine if you are not accustomed to doing that sort of thing. People like us have a curse, we have to know where each electron goes in our home, we know when the sun came up last August, and how much wind we got in December two years ago. When you have a finite amount of electricity to work with, you have to work with it. Leaving the TV on, or even owning one, becomes a double edge decision process.
Having said that, I'll give you some quick facts: Our "Cabin," is 1200 square feet, it has a home sized refrigerator, and a small deep freezer. We have Whirlpool laundry machines, a coffeemaker, microwave, two TV's and a stereo. Our usage is around 220 KWH per month, probably a fraction of what your home uses, but way more than a remote cabin should need. We use a 1.4 kw solar array, which takes up about the same area on the roof of our garage as a mid sized car might. Then there is a 900 watt wind turbine in the field, which is a bit larger than a ceiling fan, but probably too small to run our entire home. On real windy nights, it can barely do the job. In the end, we buy a little power from the power company most months, maybe five dollars worth. The good news is we can. In your remote cabin, that will not be an option. Not to fear, all you need is a generator to fill in the gaps, as most solar powered homes have them anyway. Our entire system cost around $13,000, and it runs just about everything in our home. Divide it over 20 years (240 months) and your electric bill is pretty reasonable.
If you can start small with that cabin, then do it. Just figure in minimum lighting, and at most, a very small apartment sized refrigerator that you unplug when you leave. For that, you could probably get by with a few hundred watts of solar power and no wind turbine. Turbines are really neat, they also live on a tall tower, are hard to install and maintain, make noise, and then they break down. My solar array has never had a drop of oil, never needed a screw turned on it, and it runs silently, and makes the same amount of power today it did 11 years ago. For a small system, I'd go with golf cart batteries, maybe 4 of them wired for 12 volts, and a 1500 watt inverter. Then do some DC lights, in particular LED light strips in a few key places, they are really efficient and work even if the battery is too low to fire up the inverter. Two or three hundred watts of solar panels, a charge controller (Xantrex C-40 for example) and the 4 batteries and inverter might set you back $1500, but if you learned how to hook it up, and did the work yourself, you would actually understand it and be in a good position to expand or build a larger system one day without someone selling you a bill of goods. It is pretty easy to add wind later if you want to. Southwest Windpower is a good example, they have a small 300 watt turbine that has its own internal regulator, just connect the two wires coming out of the bottom to the 12 volt battery and let it go. There are others, just get one that is designed for battery charging, not direct intertie to the utility grid. The 300 watt turbine costs about $600. Then when you are running short, you can run your generator, which can recharge the battery and run your small loads simultaneously, so you only have to run it an hour or two every few nights.
What you need to do is get educated first. Get a sub to Home Power Magazine, then try to get to one of the energy fairs listed in the mag. We did 12 years ago, and here we are today. Try not to put too much weight on sources like this, in my experience living with and teaching solar and wind in the local schools, I've found there are three things in vast supply, sun, wind and missinformation. Lots of people on these websites are happy to offer their expertise in this area, having never laid a hand on a wind turbine or solar panel. Get the mag, read the books and look up the sources, and you can learn from people like you and I that have already been there, not the ones reading the interesting articles in Popular Science.
