greenhouse effect

The Greenhouse Effect The greenhouse effect, as defined in the dictionary, is the effect produced as greenhouse gases allow incoming solar radiation to pass through the Earth's atmosphere, but prevent most of the outgoing infrared radiation from the surface and lower atmosphere from escaping into outer space. Even though this process occurs naturally and has kept the Earth's temperature about 60 degrees Fahrenheit warmer than it would otherwise be, current life on Earth could not be …

…do not cause pollution. Improved technologies allow us to use sunlight, wind, water, biomass, and even the heat within the earth to make the electricity we use everyday. Because these resources are either continuously available (such as sunlight and wind), or are capable of replenishing their stocks (such as wood), they are called "renewable energy sources." Generating electricity from renewable energy sources can result in substantial reductions in emissions of greenhouse gases and other pollutants.
