It's expensive, intermittent (no sun = no energy), and efficiency ranges from 15% to 20%.
the sun has solar energy so that is one way it is started.
The energy from the Sun, solar energy drives all the process important to life on Earth.
solar energy
The idea is to harness the potential energy of the water, when it is at a certain height. The water has to be made to go down, to harness this energy.
Solar panels harness energy from the sun--Solar energy!
It is difficult because the solar panels are really expensive.
include the use of photovoltaic systems, concentrated solar power and solar water heating to harness the energy budnetdesign.com
Solar energy is one of the environmental friendly ways to harness energy. It does not cause environmental pollution. It will be the energy of the future.
why is it important to use solar energy in Pakistan
Solar panels were invented to harness the Sun's energy in an electrical form
They harnessed the horse to the post.Imagine what might happen if it were possible to harness solar energy fully.
Not really. Solar energy exists with or without someone to appreciate it. The technology to harness solar energy does require invention. Solar panels are an invention, for example.
Using solar energy is especially appealing because it is free. It is also environmentally friendly. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy.
the most important use of solar energy is to make electricity.
It's expensive, intermittent (no sun = no energy), and efficiency ranges from 15% to 20%.
the sun has solar energy so that is one way it is started.
