Lights don't use energy when they are off.
we could use less energy by not not using the TV so much or by turning of the lights when not in use.
Not much. Electric lights do not use much energy, especially low-energy compact fluorescent lights. A typical 12-watt bulb runs for 80 hours to use one unit of electricity costing about £0.15.
The diagram below shows a picture of a slankey diagram. Energy is weighed in kj (kilo joules). the electrical energy represents how much energy you started with. The light energy represents how much energy you used for the lights. The heat energy represents how much energy you did not use for the lights but you used it for heat.
Lights use energy. Turning them off saves energy.
NO,they use the same amount of energy as any other light; But they do not use any POTENTIAL ENERGY.
Lights and computers use electrical energy. The production of heat is an unwanted side effect, but it gets produced from the use of this same electrical energy.
LED lights are so much efficient when compared to other types of lights. They use light emitting diodes which are not only durable but also use up less energy thus reducing on the overall consumption.
good question, alot, GO OUTSIDE
You can find home lights that do not use much electricity by goign to any walmart or home depot and look for love energy electric bulbs or if you want to spend more money there are more products there
LED lights use less energy than Xenon lights and last much longer. They are also far more affordable than Xenon lights and come in a range of color levels that are less harsh than Xenon.
alot think about it lights air ovens and warmer things for food computers if your school has them and copiers that's alot of energy
To save energy, unplug all of your devices when not in use. This phantom energy accounts for much energy used throughout the year and adds up. Turn off all lights when not in use, and be smart about using the heat, if electric.
The best energy efficient lights are LED lights. They are very small and use very little electricity, but they are brighter then most conventional lights.
By turning off lights or other devices you don't use and by installing energy-saving equipment (especially lights).
Energy is not stored in lights (not electric ones at least). Energy is used by lights.
They do use about a quarter of the energy as normal bulbs.
Nothing that requires to be switched on to a power source can save energy , but neon lights use less than some others.
Turning off the lights does not actually save energy; energy not burned by the lights is simply run into the ground. It will save you $$, but not save energy. However, turning off the lights does send a market signal to electricity producers, informing them that current electricity production is too high (because it is being wasted) and decreasing future loads.Conserve energy? It completely stops the use of it. How much more can you conserve?update: Hopefully the person above is taking their own advice and not voting or reproducing :-) "It completely stops the use of [energy]?" No, it stops your use of it, but the energy company still burns it if you don't use it. Only when we stop using it on a large scale does the energy company not produce as much, and we then save. Turning off that light right now? Earth hour? Not saving the planet or any energy. Only if we do it ALL THE TIME.
Well, using energy is using energy. You use energy for your house, car, lights, practically everywere! If this doesn't answer your question.... then I'm sorry. My mistake.
switch off lights when your not using them only boil as much water that you need don't use too much water in the shower switch off the PC when not in use
You can use energy-efficient light bulbs, use a timer for lights, use solar energy, get better insulation, and so forth.
