or Long Fluorescents using plasma discharges use only 1/4 of the energy and heat of incandescent lights‚ which derive their light from heating filaments hot enough to emit visible light. If every home changed their five most used lights‚ they would save $60 per year in costs. This would also be equal to 21 power plants. The fluorescents also last up to 10 times as long. Replacing one bulb means 1‚000 pounds less CO2 emitted over the compact fluorescent’s lifetime. Traffic signal LEDs

Discussion of Results and Scientific Explanation: In order to observe how much a chemical substance absorbs light a spectrophotometer can be used. A spectrophotometer measures the amount of light absorbed by measuring the difference in the intensity of the light before and after a beam of light passes through a sample solution. The area in which light is absorbed can provide information about the molecule‚ such as the concentration‚ by identifying the most preferentially absorbed wavelength.1

How to save energy at Home by Sivam in Home / Interior Design 1. Turn your refrigerator down. Refrigerators account for about 20% of Household electricity use. Use a thermometer to set your refrigerator temperature as close to 37 degrees and your freezer as close to 3 degrees as possible. Make sure that its energy saver switch is turned on. Also‚ check the gaskets around your refrigerator/freezer doors to make sure they are clean and sealed tightly. 2. Set your clothes washer to the warm

Aim To test if - a TV; a microwave oven in use; a mobile phone making a phone call; a TV remote control; water surrounding the aerial; a thin-metal box; an incandescent light bulb; a fluorescent light bulb – causes interference with AM and FM radio reception. Hypothesis I think that a TV will affect AM reception‚ but not FM reception‚ because TV’s will give off electrical pulses which will interfere with AM radio‚ but not FM. I think
