What is the energy from the sun is called?
Solar Energy. The total solar energy absorbed by Earth's atmosphere, oceans and land masses is approximately 3,850,000 exajoules (EJ) per year. The Earth receives 174 petawatts of incoming solar radiation at the upper atmosphere.
What is the relationship between coal and solar power?
They can both be used to generate electricity. Coal is solar energy trapped by plants millions of year ago. It contains toxic materials including mercury that is released into the atmosphere when it is burned. The carbon dioxide removed over millions of years is released quickly into the atmosphere. Solar power is clean but cannot be cheaply stored to provide energy on cloudy days and at night. It may be cheaper to combine solar and coal energy sources to overcome the limitations of both. For instance solar thermal energy can be used to turn coal into gas, which can be cleaned to remove toxic chemicals. The solar-gas can be stored to generate clean energy 24 hours a day. A further description of how this might be done, combining solar and coal energy is here: http://blog.gerbilnow.com/2011/11/energy-business-opportunity.html
What cause the amount of solar energy received in a particular area to change throughtout the year?
its the clouds change in the area
Applications of solar cell?
SOLAR ENERGYSolar energy can be converted directly into other forms of energy, such as heat and electricity.The major disadvantages of solar energy are:our inability to control or predict how much solar energy arrives on the earth's surface at any place and,our technology to date requires that a large surface is required for collection of useful amounts of solar energy.The strength of the solar energy available at any point on the earth depends, on the day of the year, the time of day, and the latitude of the collection point. The amount of energy collected can be further changed depending on the orientation and shape of the object doing the collection. Insolation is a measurement of the amount of solar energy that reaches the surface of the Earth. The amount of insolation an area receives depends upon the Sun's angle, the amount of dust and water vapour in the air, and the amount of cloud cover. Less than half of the radiation energy we receive from the sun makes it to the ground. The rest is absorbed by the atmosphere or reflected back out into space.The strength of solar radiation at the outer edge of the earth's atmosphere when the earth is taken to be at its average distance from the sun is called the solar constant, the mean value of which is 1.37 106 ergs per sec per cm2, or about 2 calories per min per cm2.Solar energy is used for heating water for domestic use, space heating of buildings, drying agricultural products, and generating electrical energy.One of the first examples of using solar energy was the used of a solar collector box to cook food during an expedition into Africa in the 1830's by British astronomer John Herschel. Today it is used widely for many things. Solar thermal or heat energy is used widely in Australia for heating water for our domestic use in Solar Water heaters. This is an excellent and economic energy solution as, by using the sun's heat for making our hot water, we cut down on the amount of fossil fuels needed to be burnt to supply electricity to do the same thing. The technology is now developing which will use solar thermal energy to produce steam at high enough temperatures and pressures to drive steam turbines for electricity generations.We are also able to harness radiant or solar light energy. Radiant energy is produced in the sun as a result of nuclear fusion reactions and is transmitted to the earth through space by electromagnetic radiation in quanta or packets of energy called photons. This light energy can be utilised by a process called photovoltaics, which produces electricity directly (Photo meaning light and voltaics relating to electricity). This process is being used more and more as the technology is developed and becomes more economic. It is used widely in solar powered calculators and other such devices.How many ways can you think of that the sun's energy is used directly today?
Is solar energy unlimited?
Technically it is not unlimited because the Sun is powered by fusion. Hydrogen nuclei are compressed into helium nuclei with the loss of a small amount of mass that is converted into an equivalent amount of energy. When all of the Sun's hydrogen has been fused into helium, the Sun will no longer be able to power itself as it does now. This will occur in about 5 billion years.Solar power facts: The total solar energy absorbed by Earth's atmosphere, oceans and land masses is approximately 3,850,000 exajoules (EJ) per year. In 2002, this was more energy in one hour than the world used in one year.The amount of solar energy reaching the surface of the planet is so vast that in one year it is about twice as much as will ever be obtained from all of the Earth's non-renewable resources of coal, oil, natural gas, and mined uranium combined.Yearly Solar fluxes & Human Energy ConsumptionSolar3,850,000 EJWind2,250 EJBiomass3,000 EJPrimary energy use (2005)487 EJElectricity (2005)56.7 EJ
How much solar energy is used a year?
not enough
What are the advantages of Solio Solar Chargers?
The advantages of Solio Solar Chargers are that they can store energy for up to a year, can be used to power lights, radios and wireless electronics, and can be charged using solar energy or wall outlets.
What element can be used as a fuel in alternative cars?
you can use solar power because 1 minute of sunlight is a year supply of solar energy!
How much does a solar energy car cost a year?
A solar powered car may cost from $50000 AUD ($44944) to $2.5 million AUD ($2.25 million).
What year was solar energy invented?
The very minute the Earth was formed...Solar energy has been shaping the planet ever since...
Can solar energy be collected all year round?
Yes. Any time of year that the sun shines, solar energy can be collected. There are times when output may not be as high, but it is possible.
How much energy can the sun provide?
According to the American Solar Energy Society, enough sunlight falls on the earth's surface each minute to meet world energy demand for an entire year.
What is the energy from the sun is called?
Solar Energy. The total solar energy absorbed by Earth's atmosphere, oceans and land masses is approximately 3,850,000 exajoules (EJ) per year. The Earth receives 174 petawatts of incoming solar radiation at the upper atmosphere.
How much energy does Australia use in a year?
Australia uses fossil fuels (coal, oil, natural gas), solar energy, hydroelectric energy and wind-generated power.
Is solar energy only available during summer?
Depends on where you are on the world. Solar energy is only available when the sun shines. Close to the equator, solar energy is about equally available year round. further away from the equator, the availability of solar energy is about proportional to the amount and intensity of sunlight.
How much energy is used by Disney World each year?
150,000,000
How much does installing solar panels save in electricity costs in an average year?
There are a variety of factors that determine the energy savings by installing solar panels. You can figure a 2 to 1 ration in savings.
