MS. STEPHENSON’S CLASS If someone told you that there is a free, clean, endless source of energy to provide you with heat and air conditioning for your home, along with power to run batteries, fans, toys and lamps, etc., would you want to try it? Look through our pages and learn more about it. Solar energy is the energy from the sun It influences the climate and weather and supports virtually all life on earth Can be converted to usable energy Travels to the earth in the form of electromagnetic radiation Sunlight travels to the earth in approximately eight minutes from 93,000,000 miles away at 186,282 miles per second Two billion people in the world have no access to electricity The earth receives more energy from the sun in just one hour than the world uses in a whole year. The world has become dependent on oil for much of it's heating and transportation needs Accounting for only five percent of the world’s population, Americans consume 26 percent of the world’s energy Solar power consumes none of our energy resources, makes no contribution to air, water, or noise pollution, does not pose a health hazard Use of solar electric systems decreases the amount of local air pollution Materials that absorb and store the sun’s heat can be built into sunlit floors and walls. They heat up during the day and slowly release heat at night. A photovoltaic cell is a device that generates electricity by reacting to the suns light rays. To generate a useful amount of electricity, many of these cells are combined in a solar panel. These panels are also known as photovoltaic cells, solar cells and solar panels. Reflectors are to face the sun Preheat using thermometer Use same recipe as for conventional oven Place food into a dark, covered pot Double the conventional cooking time Germany and Japan lead the way in solar usage The future will happen with solid investment now Experts feel that in five years, solar power will be cheap enough to compete with conventional electricity Solar power saves our world, And it cooks our food. It helps conserve our power bill. Are you listening, dude? Solar power helps us all, By saving energy. It can work for all of us. Wouldn’t you agree?
