The Cathode Ray Tube\nAlmost all TVs in use today rely on a device known as the cathode ray tube, or CRT, to display their images. LCDs and plasma displays are sometimes seen, but they are still rare when compared to CRTs. It is even possible to make a television screen out of thousands of ordinary 60-watt light bulbs! You may have seen something like this at an outdoor event like a football game. Let's start with the CRT, however, because CRTs are the most common way of displaying images today. \n\n \nInside a CRT\nAs you can see in the below drawing, there's not a whole lot to a basic cathode ray tube. \n\n \nTo see the rest of this go to: www.howstuffworks.com\n \n\n\n\nThere is a cathode and a pair (or more) of anodes. There is the phosphor-coated screen. There is a conductive coating inside the tube to soak up the electrons that pile up at the screen-end of the tube. However, in this diagram you can see no way to "steer" the beam -- the beam will always land in a tiny dot right in the center of the screen. \n\nThat's why, if you look inside any TV set, you will find that the tube is wrapped in coils of wires. On the next page, you'll get a good view of steering coils. \n\n\n \n\n\n\nThe terms anode and cathode are used in electronics as synonyms for positive and negative terminals. For example, you could refer to the positive terminal of a battery as the anode and the negative terminal as the cathode. \n\nIn a cathode ray tube, the "cathode" is a heated filament (not unlike the filament in a normal light bulb). The heated filament is in a vacuum created inside a glass "tube." The "ray" is a stream of electrons that naturally pour off a heated cathode into the vacuum. \n\nElectrons are negative. The anode is positive, so it attracts the electrons pouring off the cathode. In a TV's cathode ray tube, the stream of electrons is focused by a focusing anode into a tight beam and then accelerated by an accelerating anode. This tight, high-speed beam of electrons flies through the vacuum in the tube and hits the flat screen at the other end of the tube. This screen is coated with phosphor, which glows when struck by the beam.

In most cases, the television needs to 'warm-up' its cathode ray tube before it can start to display an image on the screen.\n\nThe audio coils require much less charging time and can start to emit sound sooner than we can see the image on the television.

A typical computer uses between 100-150 watts per hour.  But your computer usage will vary depending on how many peripherals and components are installed.  In the United States, rates vary wildly.  I'm in the more expensive area of the country where we pay about 20 cents per Kilowatt Hour.  This amounts to about $15-20 per month per computer.\n\nAnd to the guy who said the TV uses more... you're WRONG.  TVs use between 50 and 100 watts. (except for the larger TVs).\n\nI'm not sure if they make a UK equivalent, but you might want to invest in a device like the Kill-A-Watt meter (google it) - it will tell you how much electricity is being used. \n\nAlso, idle time vs. use time can see the wattage change significantly.  Using my the network can increase wattage use by about 15 watts...\n\nAsking the electric company sounds good but is silly - I've done that, they tend to tell you the computer uses 300 watts (because that's the average power supply in a computer).  Problem is, just because the power supply can provide 300 watts does NOT mean that that's what it uses.  It's kinda like saying your light socket uses 150 watts because it can use a 150 watt bulb... even when you only use a 60 watt bulb.

This is suppose to be common sense by now well unless you're 6 yr old then that's different. So I guess you need read this:\n\nsolar energy, any form of energy radiated by the sun, including light, radio waves, and X rays, although the term usually refers to the visible light of the sun. Solar energy is needed by green plants for the process of photosynthesis, which is the ultimate source of all food. The energy in fossil fuels (e.g., coal and oil) and other organic fuels (e.g., wood) is derived from solar energy. Difficulties with these fuels have led to the invention of devices that directly convert solar energy into usable forms of energy, such as electricity. Solar batteries, which operate on the principle that light falling on photosensitive substances causes a flow of electricity, play an important part in space satellites and, as they become more efficient, are finding increasing use on the earth (see solar cell). Thermoelectric generators convert the heat generated by solar energy directly into electricity (see thermoelectricity). Several projects have produced electricity on a large scale by using the solar energy available in desert areas. In one system, large numbers of solar batteries generate electricity for Coconut Island, off the coast of Australia. In another, oil flows through pipes that are set in reflecting parabolic troughs that can trap the heat from sunlight falling on them. The heat from the oil is then converted into electricity (see power, electric). Heat from the sun is used in air-drying a variety of materials and in producing salt by the evaporation of seawater. Solar heating systems can supply heat and hot water for domestic use; heat collected in special plates on the roof of a house is stored in rocks or water held in a large container. Such systems, however, usually require a conventional heater to supplement them. Solar stoves, which focus the sun's heat directly, are employed in regions where there is much perennial sunlight.\n\nAlso there are tons of info on this on the web just go to Yahoo search or Google and type in Solar Energy. It's not that hard.

A common garden variety TV screen is a Cathode Ray Tube- the screen itself is a phosphor coated glass surface attached to the vacuum bottle and electron gun assembly that makes up the rest of it. In operation the electrons from the gun at the rear of the thing are electromagnetically accelerated to the phosphor screen, and scanned by electromagnetic deflection back and forth over the phosphor, making little dots of light that cumulatively make the "picture"- each dot is a "picture element" or pixel the whole accumulation makes a recognizable image. and if you like I can explain how the thing work in color, too.

ELECTROMAGNETIC ENERGY is ENERGY coming from the POLARIZEd motion of ELECTRONs, but i don't think LIGHT is ELECTROMAGNETic ENERGY. For me, LIGHT is a FORM of QUANTUM ENERGY.

The issue about standby mode is not what the instantaneous consumption is, it is the amount of time that it remains on standby. In real terms standby on a telly may use only 5% of the power used when it is on. But say you watch telly 2 hrs a day, and leave it on standby for the other 22, you have used 1 x 2 power units watching it (=2) and 0.05 x 22 units in standby (=1.1)\nIf this example is correct, then 1.1 / 3  (37%) of the units your telly consumes are consumed in standby, which is a lot more than the 5% would seem to indicate. So turn 'em off
