Clare Boone's PowerPoint (Solar Power) 2009

advertisement
The word solar
comes from the
Latin word solaris,
which means sun.
So solar power
comes from the
sun.
Solar Power
The two most important
kinds of solar energy
are…
Light
heat
Solar power is
really important
now because out
sources of
natural energy
such as gas, oil,
and coal are
running out.
Heating with Solar Energy
Some people mount
The heated air
large, flat dark colored
moves by gravity
solar collectors on their
or by fans to heat
house to collect the sun’s
the house
heat.
After the air is heated by
the sun, the air moves to
the house where it can be
used.
Electricity from the Sun
In the 1950s, scientists
found a way to make
electricity from the sun’s
energy.
Solar cells, which are made of
a mineral called silicon, are
placed into panels. The solar
cells absorb the energy from
sunlight and change it into
electricity.
Some things which use
solar-powered cells
today are calculators,
watches, toys and
outdoor lighting for
signs.
Vroom,
Vroom!
