Solar Energy Facts
Heat from the sun can be captured and used as a form of
solar energy. In order for this process to take place, some
form of solar technology must be used. There are two types of solar technology: passive and active solar. These types of solar technologies differ in the way in which solar energy is captured.
Solar energy is taken from the light from the Sun’s
rays that hit the Earth.
Solar energy can be used to make electricity and
other forms of energy.
Thermal energy from the sun was first used by
British astronomer John Herschel.
In order to heat objects such as
swimming pools, solar energy
is converted into thermal
energy.
Solar cells
can directly use
sunlight to generate
electricity.
Soler energy is a beneficial source of energy because its
generation does not affect the environment and nor add to pollution.
Solar energy can sometimes be difficult because the amount of sunlight an area receives varies.
Solar energy is the most plentiful form of energy found
on Earth because it is found anywhere the Sun hits.
Although solar energy is abundant, it is difficult and
expensive to transform into a usable form.
There is enough solar energy generated by the Sun to
fulfill Earth’s electrical needs without the use of other
forms of energy.
The world’s largest solar energy power plant is located in the United States in the state of California.
Passive solar energy does not require any machinery
because solar energy is used directdy.
With active solar energy, a device is needed that collects
solar energy so that it may be pumped into an area.
Since the 1950s, the space shuttle has used solar energy
to power its space eraft.
It takes less than 10 minutes for the light from the Sun
to reach Earth.
