Even though only a small fraction of that heat ever reaches the earth it is still more then enough to power the whole world.
People seemed to realize the importance of the sun around 30, BC. This was when people first started planting crops of wheat. They realized plants did better when planted in the sun over the shade. This caused them to worship the sun as a God. Many cultures built large and extravagant temples to worship the sun in. Other cultures built places to observe the sun in, such as Stonehenge in England. There are three main types of solar power essay panels. They are flat plate collectors, focusing collectors, and solar cells.
The first kind is a flat plate collector, solar power essay. Flat plate collectors are fastened on the top of the roof of a house, solar power essay. They usually either heat the house or its water, solar power essay. A flat plate collector consists of a black rectangular frame, two or three sheets of glass, and copper plumbing. A flat plat solar power essay uses the greenhouse affect. The sunrays heat the water-filled copper tubes. Then the water is used to heat the home or water. Another type of a solar panel is a focusing collector, solar power essay. They consist of a mirror or mirrors which are focused in one spot. Some focusing collectors are solar furnaces, parabolic dishes and troughs and power towers. The first type is a solar furnace.
A solar furnace consists of many mirrors that are aimed at a large curved mirror that is aimed at a large steel building. This building can get as hot as 5, F. Scientists use solar furnaces to run experiments to see how solar power essay materials react to extreme heats. They are also used industrially to melt metals. The next kind of focusing collector is a parabolic trough and dish. A parabolic dish looks just like a satellite dish except the dish part is to reflect the sunrays onto the vocal point which is filled with oil. The heated oil is used to produce steam to turn a turbine. A parabolic trough uses the same principles as a parabolic dish. The only differences are how they look, the mirror is shaped like a large feeding trough and the vocal point is an oil filled tube.
These are used for either commercial such as in a power plant, solar power essay. The last focusing collector is a power tower. A power tower has many mirrors all focused on a large tower. This tower gets extremely hot. The tower is filled with oil. When the oil is heated it is piped to a power plant where it is used to produce steam that turns a turbine. These are used for power plants. The final type of solar panel is a solar cell. A solar cell usually consists of two layers of silicon that produce an electric charge which is picked up by wires that are laid across the silicon. Solar cells can be used for anything from powering an isolated phone booth to a whole city or even an airplane. Solar Energy started around 30, BC when people first desalinized water, or took the salt out of salt water.
In 1, BC a king had the water in his castle heated by the sun. Romans passively heated their homes in about AD. In a passive solar home there is no machinery, but there are windows and the floors and windows are made of materials that absorbs heat, like solar power essay. Solar heating was not used until the late sixteenth century when European scientists started experimenting with the power of the sun. In a Swiss scientist, Horace Benedict de Sasure, built the first modern solar water heater. In Antoine Lavoiser made a printing press powered by the sun. Later in in Chile a solar desalinization system was made. Also in the first solar cells were made. Solar cells when originally made they were very expensive and were not available on the market. Now you solar power essay buy solar cells cheaply.
Today we use solar power to do many things. We use solar power for everything from calculators to large power plants that can power large cities, solar power essay. Most common solar power is used for small things. Many calculators are run by solar cells so they will never run out of batteries, solar power essay. Some watches run on solar cells, too. Also you can buy radios that run on solar cells. There are also many big things that run on solar power. Almost all satellites run on solar power, because otherwise they would run out of power. There are also large desalinization plants that use solar power in places where there is little or no fresh water. There are solar furnaces in many countries. Solar power is also used commercially and residentially.
It is also used for many forms of transportation, but these are all in the experimental stage now. Solar powered cars may soon come out. There are three forms of indirect solar power. They are wind power, waterpower, solar power essay, and ocean thermal energy. You might think these have nothing to do with each other or solar power but they do, in some way they each use the sun. The first type is wind power. The reason this is solar power essay form of solar energy is because the sun heats the air that creates air currents, or wind. The wind turns propellers that turn turbines which creates electricity. Wind power has been used for a very long time, solar power essay. Places in Europe like the Netherlands have had windmills since the Middle Ages.
Though these windmills were used to pump water or to grind grain. The next form is waterpower. This is considered solar power because of the hydrologic cycle. The hydrologic cycle is water evaporating from bodies of water then coming back to earth in different places. This allows them to go back through dams to produce electricity. The water turns turbines, which then create electricity, solar power essay. Waterpower is also an old process it used to be used at sawmills and to grind down grain. The last kind of indirect solar power is ocean thermal energy. Ocean thermal energy is a power plant that uses the difference between the surface temperature and the temperature of the bottom of the ocean to produce electricity.
When the cool water meets the hot water it produces steam that turns a turbine to produce electricity, solar power essay. The electricity is then sent to land through wires. This is solar power because the sun heats it. Today the use of solar power is very limited. Today we use very little active solar heating. Though in the future many more homes will be solar heated. More homes will have passive solar heating. Scientists want to make a satellite that will orbit over one solar power essay. This satellite would have giant wings made of solar power, this satellite would beam electricity down to earth, solar power essay.
This would allow the solar cells not to be obstructed solar power essay clouds or buildings. Also ground solar power plants are predicted to solar power essay used more frequently. Another thing predicted to be popular is solar powered cars.

Nowadays many solar water heaters are also made which is very important. This system of solar energy is also contributing to saving electricity. As it is reducing the use of the modern machines which needs electrical energy to be operated. Also, it stops deforestation as people no longer need to cut trees for woods to warm the water. And many more reasons. The uses of solar energy. There are many uses of solar energy. The use of solar energy is very important.
Artificial photosynthesis and solar agriculture can also be done by using solar energy. Solar power is the alteration of sunlight into electricity, by directly using photovoltaics PV , or indirectly using concentrated solar power. Solar energy is also used for solar warm water systems which use daylight or sunlight to heat up water. The most frequent types of solar water heaters are evacuated tube collectors and glazed flat plate collectors. These are by and large used for domestic hot water; and unglazed plastic collectors which are mainly used to heat swimming pools. Solar cookers are also available nowadays.
Solar cookers use sunlight for working or for functioning i. cooking, drying etc. Agriculture and horticulture hunt to optimize the capture of solar energy in order to optimize the efficiency of plants. Some of the techniques such as the timed planting cycles, staggered heights between rows tailored row orientation and the amalgamation of plant varieties can pick up crop yields. While daylight or sunlight is generally well thought-out an abundant resource, all these help us to know the importance of solar energy in agriculture. Some transportation means also use solar panels for supplementary power, such as for air conditioning, to keep the interior cool, which automatically reduces the fuel consumption. By nineteen hundred ninety-five, passenger boats incorporating PV panels started appearing and are now used expansively.
Conclusion to Solar Energy Essay: — People started to think about the use of solar energy from the latter half of the 19 th century. But still, it has not covered the need for our requirement so far.
