 Many Uses for Solar Energy
Solar energy-energy derived from the sun in the form of solar radiation.- http://dictionary.reference.com/browse/solar+energy
Solar energy is one of the most efficient forms of renewable energy. It is also environmentally friendly because it gives off no http://dictionary.reference.com/browse/pollution pollution. The only pollution that maybe produced is during manufacturing in factories, transporting and installation. The initial investment maybe high, but the http://dictionary.reference.com/browse/electricity electricity is free, and will eventually pay for itself. The installation of solar energy is more cost effective.
Let’s take a look at some of the benefits of solar energy. It is a renewable source that is never ending. It can harness electricity in remote areas. It also produces electricity quietly. It can be produced on overcast days due to new technology. There is no need to worry about space, it can be put on rooftops.
By using solar energy, there is less dependency on http://dictionary.reference.com/browse/fossil+fuels fossil fuels. There are however a few disadvantages. The weather can affect http://dictionary.reference.com/browse/efficient efficiency as well as pollution. Solar energy can only generate during daylight hours. However, the energy can be stored for later in use by using a battery.
Solar energy has the ability to heat and cool through solar architecture. You can also use solar energy for http://dictionary.reference.com/browse/disinfection disinfection, solar hot water and solar cooking. This http://dictionary.reference.com/browse/renewable renewable source of energy can also be used for drying food and http://dictionary.reference.com/browse/pasterurization pasteurization. There are three types of cookers. The box cooker was first built in 1767 by Horace de Saussure. It is an http://dictionary.reference.com/browse/insulated insulated cooker with a transparent lid. The panel cooker uses a reflective panel to direct sunlight onto an insulated container. The reflector cooker requires direct sunlight and must be repositioned to track the sun.
There are two types of solar energy. Active includes the use of http://dictionary.reference.com/browse/photovoltaic+cells photovoltaic panels and solar http://dictionary.reference.com/browse/thermal thermal collectors to harness the energy. Passive is orienting a building to the sun, selecting materials that contained http://en.wikipedia.org/wiki/Thermal_mass thermal mass and designing spaces that naturally circulate air.
There are many advantages to solar energy. This is a renewable source that will never diminish because the sun will always shine somewhere in the world. It is amazing that we can cook as well as heat our homes and save money and same time. Even though the initial cost may be high, it is well worth the investment. Solar energy is becoming more popular because of the benefits that it produces. With all the concern of global warming, solar energy can help reduce this. We could possibly use this as major source for our needs.
