Solar Energy Global Warming is the slow increase of the average temperature of the Earth’s atmosphere and oceans. Global Warming is a phenomenon caused by the buildup of greenhouse gasses in the atmosphere that trap heat from the sun in the atmosphere. Energy in the form of heat comes to the Earth as sunlight. The heat cause by sunlight would normally leave the atmosphere as a form of infrared radiation. Greenhouse gases however trap the radiation causing the heat to remain in the atmosphere. The gradual increase in heat due to the buildup of these gasses and the heat that these gasses trap is called the "greenhouse effect." This “greenhouse effect” is what gives the Earth’s atmosphere a lot of its warmth. However, as the amount of…show more content…
Solar energy is one of those solutions. Solar energy is the cleanest, most efficient, and cheapest form of renewable energy. The physics behind the harnessing of solar energy is the law of the conservation of energy. Solar energy is defined as the energy that comes from the suns radiation. Solar energy can be harnessed and used through, the law of the conservation of energy. The law of conservation of energy states that the energy within a system is constant. The law also states that energy cannot be created or destroyed it can only change forms. Solar energy in the form of sunlight can be converted into electricity. The electricity created from sunlight is called solar power. In order to turn sunlight into electrical energy a solar panel is used. The solar panels are made up of photovoltaic cells. These cells convert sunlight into direct current electricity throughout the day. This direct current is then transformed into the usable alternating current electricity by the inverter. When more energy is produced than is needed, like on bright sunny days, the extra electricity is automatically while the rest is stored in a battery. The only setback of solar energy is that it isn’t always available. However when the sun goes down or the weather blocks sunlight the energy that was previously stored will be used. This energy feeds directly into the breaker supplying electricity to the house or building. This electricity power the devices in a house like the
