Reading
Energy source derived from Petroleum and gases are non – renewable sources of energy. The energy source has limites availability and will eventually run out. A human needs other energy source or alternative energy to fulfill their needs. The alternative energy sources come from renewable energy sources, for example sun, wind , water, geothermal, ocean waves, and bio.
The purpose of alternative energy is reducing fossil energy usage such as petroleum, because to get it takes a long time. Besides that alternative energy also reduces environmental damage. Smoke pollution causes of petroleum spreads into the air and global warming.
Write

1. Mention the examples of alternatif energy!
Answer: Sun, Wind, Water, and Geothermal energy
2. The energy available in nature and can be renewed is ……… energy.
Answer: Alternative
3. What is the Alternative energy used for sailboat?
Answer: Wind
4. The Alternative fuels that come from living things is ……
Answer: Bio fuel
5. The Alternative energy that can be used for hydropower is ………….
Answer: Water
Reading
The alternative energy is energy that can be renewed, available in nature, and not exhausted. The examples are sun, wind, water, and geothermal energy.
Sun
Sun is the main energy source on the earth, all energy on the earth comes
from the sun.
Wind
Wind is an air movement due to air pressure, wind can be used for sailboats
and Windmill.
Water
The heavy water is a source of motion energy, which can be used for
hydropower plants.
Geothermal Energy
Geothermal energy derived from heat stored under the surface of the
earth, the center of the earth is forming from a layer of hot relief.
Sea wave
The wave also produce a lot of energy, this energy can be converted into
an electrical energy.
Bio Fuel
Bio fuel is a fuel derived from living things (plants, animals). Examples of
the bio fuels derives from plants are sunflower, distance plants, cassava,
sweet potato, and sago. Example of the bio fuel comes from animals is
animals feces.
