The Newest Thing in Lighting - LED Lighting and What It Can Do by Paul Forte
... have that ability though the energy savings will be on a huge scale. The traffic lights I mentioned earlier use a 10 watt LED bulb to replace a 150 watt bulb used in the past. To give you an idea how much this saves at 12.5 cents a KWH, the savings for a single bulb in one year is about $75. Pretty amazing, especially when you consider some 150,000 traffic lights across the country have been retrofitted with these new LED light bulbs. That is an energy savings of over 11 million dollars.

LED Lighting - An Energy Efficient Alternative by Margarette Tustle
... In general, incandescent light bulbs have a filament, while lights powered by LED utilize the movement of electrons over an arc. This movement of electrons over the arch is what produces light. If the arc has a tighter radius, the light emitted will be brighter. The power is provided by a semiconductor and will last as long as its transistor. These lights use little energy, relatively, as they provide large amounts of lighting. LED lighting is used nearly everywhere you use light.

LEDs: The Light of the Future by William Sutherland
... Phillips Electronics is working on LED bulbs that can screw into existing light sockets, while besthomeledlighting.com already offers LED screwable bulbs -- one consisting of 70 LEDS that emits a "warm white color similar to the light from an incandescent bulb" [17] using only 3 Watts of energy and another LED bulb that actually changes colors when lit). With these efforts along with the adoption, exploitation, and production of LED technology by growing numbers of companies, it is ...

At Home In Your Home Office by Akhil Shahani
... Halogen bulbs are energy efficient light sources, while warm fluorescents on the ceiling might be a good idea. Very important – make sure the light sources are placed above or behind your computer, and are not reflected off the screen. If you can’t, better stock up your medicine cabinet with Aspirin. While we’re on the subject of electricity, let us also remind you to fit out your home office with a number of electrical outlets. Power surges can kill your equipment, so the decision to ...

Craft Show Organizing 101 by Lauren Sorgaard
... The last thing you want to do is show up and set your table up with fancy lighting only to find out that you weren’t allowed to use 1000 strings of lights. Take careful note of whether or not they supply an electric source, exactly how much space you are allowed to use and whether there are any display restrictions. While you are preparing your display area, it is a great idea to tape off the size of your allotted space either in your basement or garage (use your living room if you have to) ...

What is Solar Power? by Anne Clarke
... For example: If in an especially sunny climate one can produce enough power from the sunlight to run a 100w light bulb from merely one single square meter of solar panel. b) What is solar power? What can it do? Other examples of what is solar power? are examples of some of the different things that solar power can do. Read carefully if you really want to understand what is solar power? 1) Solar water heating is a part of what is solar power. Basically, heat from the sun is used to heat ...

Advancing Technology Through Mice by Andy Alt
... I firmly believe that a fourth button will either cause a pizza to be delivered to one's door, or pop up a dialog box which states how many light bulbs to buy next time one goes shopping. After the fourth button comes into existence, I foresee more wheels being added. Honestly, I don't see the need for ever having more than four wheels. After the four button/four mouse wheel is accepted into society, technology must further advance -- as it always has and always will.

Green Travel – Making Better Environmental Travel Choices by Susanne Pacher
... Alternatively I would be able to supply 2 energy saving light bulbs to a small community in the developing world. Both options would be £30. I also checked their carbon emissions driving calculator. If I travel 400 km (250 miles) every week in a car with an engine size between 1.4 and 2 litres, I would generate 4 tonnes of CO2 a year, which would take 5 trees to offset. In addition to planting trees, you can also purchase “carbon offsets”. A "carbon offset" is actually an investment in a ...
