depend on electricity to power most of our daily activities.
How can we make the electricity we need for our future? 5
2 Japan uses a lot of oil, coal, and natural gas to
make electricity. These resources are called “fossil
fuels.” Fossil fuels have some good points. They are
relatively cheap, and they can be used for many things.
However, scientists say that we may run out of fossil 10
fuels in 100 years. There are other problems, too.
Fossil fuels release carbon dioxide and other dangerous
chemicals. They increase global warming and damage
our health.

3 Japan also makes electricity from nuclear power.
Nuclear power produces a large amount of energy without
releasing carbon dioxide. However, it is difficult to control
radiation and handle nuclear waste safely all the time.
4 Now many countries are using sunshine, wind,
steam, rivers, and even ocean waves to make electricity.
These are examples of "renewable energy." Japan has
many rivers, and their power is used to produce
electricity. Their water is renewable and does not
release dangerous chemicals. However, we need dams
to use water power, and these dams can damage the
environment.
5 Research in other renewable energy technologies is
progressing. Already, Denmark gets forty percent of its
15 electricity from wind power. One quarter of the
electricity used in Iceland comes from the natural heat
in the ground. People around the world are working to
solve our energy problems.

Reyhan Jamalova is one of those people. Reyhan
is a student in Azerbaijan. When she was fifteen,
Reyhan invented a device to make electricity from rain.
Reyhan's device can power 22 LED lamps for 50
seconds. Each device uses only 7 liters of rainwater.
Its battery can store power to use later. Reyhan says
she created the device to help poor people, especially in
rainy countries. Her device is not expensive. It does
not even need power lines. It can help many people get
electricity.
7 Is there anything you can do for a sustainable
energy future? As a consumer, you can decide how
much electricity you use. You can also decide what kind
of energy you want to use. You may even be an
inventor, like Reyhan. Your actions are important.
What can you do to make your energy future brighter?
