8. Future of Solar Energy
“All buildings will feature energy-efficient
degisn, construction, and materials as well as
renewable energy technologies. In effect, each
building will both conserve energy and produce
its own supply, to be one of a new generation of
cost-effective “zero energy buildings” that have
no net annual need for nonrenewable energy”
Solar energy could generate 2.5% of the world by
2025

9. Interesting Facts
All of the energy stored in Earth’s reserves of
coal, oil, and natural gas is matched by the
energy from just 20 days of sunshine.
Even when the sun goes down solar panels are
still collecting light.
