many people around the world don’t have easy
access to the energy they need to power lights,
phones, and other electrical devices. there
may not be an electrical grid nearby, or they
may not have electrical wires to bring power
from the electrical grid to their homes—or
they may have electrical wires, but the nearest
power plant may only provide energy part of
the time, leaving people in the dark when it
doesn’t work. these people may not have much
money, so they can’t just buy lots of batteries
to power their lights. they face an energy
problem: they need access to cheap, reliable
electricity. all over the world, people from
professional engineers and energy scientists
to students, makers, and inventors are working
to solve this problem. they have designed
ways to provide portable light in places where
electrical power isn’t always available. in this
article, you’ll read about a few of them.
gathering energy from the sun
when olafur eliasson and frederik ottesen
heard that more than 1 billion people on earth
don’t have access to electricity, they wanted
to help. in many places, lack of electricity
means students can’t study after dark and
families can’t cook after the sun goes down.
it’s also harder for doctors and nurses to
treat patients without good lighting. some
people light their homes by burning a type of
oil called kerosene, but kerosene is expensive
and produces thick, black smoke that causes
lung disease—and it can cause houses to
catch fire. eliasson and ottesen decided to
invent a solar lamp that would provide light
without costing a lot of money, polluting the
air, or causing fires. their solution? the little
sun lamp, a sun - shaped light with a light bulb
on one side and a solar panel on the other.
the little sun lamp uses energy to provide light
to people who need it, but the little sun doesn’t
make its own energy. to run, the lamp needs to
get energy from somewhere else. in this case,
that source of energy is the sun. the solar panel
on the back of the lamp converts light energy
