Whats the solar energy?
Question:
Answer:
Solar power is the technology of obtaining usable energy from the light of the Sun. Solar energy has been used in many traditional technologies for centuries and has come into widespread use where other power supplies are absent, such as in remote locations and in space.
Solar energy is currently used in a number of applications:
Heat (hot water, building heat, cooking)
Electricity generation (photovoltaics, heat engines)
Desalination of seawater.
Solar Energy is energy conducted from the sun. The solar panels absorb the light/heat and converts the light/heat into energy
Solar energy is the solar radiation that reaches the Earth. Solar energy is an unlimited, renewable energy resource [for it comes from the sun].
By using solar-powered electronics, no damage is done to the environment. Photovoltaic cells convert solar energy into electricity.
Solar energy can also be easily converted, or indirectly converted into other types of energy, such as heat and electricity.
Solar energy is also essential for life [photosynthesis, which makes oxygen from plants for us to breathe]
The sun produces radiation. Some of that radiation is visible light. Visible light can be captured by solar panels and converted directly into electricity. Unfortunately solar panels are very inefficient (although they are getting better). That means that they convert only a small portion of the light into electricity. They also tend to be fragile and expensive to manufacture. Most of the energy we use comes from the sun one way or another. Even fossil fuels are the product of the conversion of solar energy long ago.
