What is the solar energy?
Question:
Answer:
According to scientists, current theory suggests that "fusion" of the element hydrogen into the element helium releases photons. When the heavier element is made, photons are released from the reactions. Photons are sometimes described as wavicles, because they can demonstrate the behavior of waves and particles, but neither a wave nor a particle can completely describe a photon. A photon has a frequency and is an electromagnetic emission. Photons from the sun come in a huge range of frequencies. Most useful to humans are the photons that heat things and cause us to see things (light).
Photons can be directed to silicon semiconductors in a solar cell. When the photons collide with the extra electron in the outer shell of an element in the silicon, the electron moves through an electromotive force, causing electric current to flow. In heating applications, the photons impart kinetic energy to the object they encounter, increasing the net kinetic energy of the body therefore increasing its temperature.
If you set out a gallon of "solar tea," the sun will heat the liquid and brew the tea for you.
Some of the most interesting solar energy is released in solar sun-spot activity. These emissions can interact with our telecommunications systems and power grids with unpredictable and sometimes disasterous results.
To date, humans harness solar energy by heating things or placing solar cells out to make electric power. The practical applications include solar heating pool water, solar heating homes, and charging lead-acid batteries for power.
Solar power describes a number of methods of harnessing energy from the light of the Sun. It has been present in many traditional building methods for centuries, but has become of increasing interest in developed countries as the environmental costs and limited supply of other power sources such as fossil fuels are realized. It is already in widespread use where other power supplies are absent, such as in remote locations and in space
its natural energy that comes from the suns rays. aka solar power.
an energy that comes from the sun
Solar energy simply is energy from the sun. It gets complicated when you talk about how you HARNESS the energy. Plants harness the energy to produce food. You can use mirrors and the light to heat water. Most commonly you think of the solar panels that convert solar energy into electricity. solar energy is great but you can only use it when the sun is shinning.
Are you sure you dont know this stuff? well basically solar energy is the energy emitted by rhe sun (light and heat). There are two reusable energies in this state. Heat energy is used by solar power plants to heat water (or other liquid) to produce steam to drive turbine generators. The other is light... in this way you use a solar cell (like the one in your calculators) to generate electricity. However, solar cells are very expensive and the efficiency is just 10%. Chemical composition of this cells enables particles to have a positive and a negative charge as light energy is present. I hope this helps you.
