electricity used to power our daily activities is still primarily
generated from fossil fuels. This
kind of power generation pollutes the environment through
the emission of CO². Moreover,
fossil fuels are finite -- and once used, are gone forever. For
this reason alone, alternative forms of renewable power generation
provide a more intelligent solution to powering our lives.
Photovoltaic systems provide energy to meet our needs without
contributing to the green house effect and are a genuine
alternative to conventional energy generation. They
are considered to be the ultimate solution because
they convert sunlight directly into electricity.
