3. Biomass energy
1. The wood, straw or other plant matter are put in a bunker.
2. The material is burned to heat a water tank.
3. the energy or power is directed to a turbine with pipes.
4. the steam is turning the blades in the – batteries are charged.
5. the charged magnet produce electricity
5. Water energy
• a dam is built to retain the water.
• Sluice gates
• water flowing trough pipes with high speed.
• millions of magnets are charged to create electricity.
9. What is non-renewable energy?
Non-renewable energy is energy from fossil fuels (coal, crude oil, natural
gas) and uranium. Fossil fuels are mainly made up of Carbon. It is believed
that fossil fuels were formed over 300 million years ago when the earth was
a lot different in its landscape. It had swampy forests and very shallow
seas. This time is referred to as 'Carboniferous Period‘.
11. What is coal?
Coal is a black or brownish-black rock composed mostly of carbon and
hydrocarbons.
Coal is made of the remains of ancient trees and plants that grew in great
swampy jungles in warm, moist climates hundreds of millions of years ago.
13. What is crude oil?
Crude oil (a non-renewable resource) is usually found in underground areas
called reservoirs. It is liquid in nature and yellowish black in color. They
are composed mainly of hydrocarbons and organic compounds. They are
usually discovered by oil prospecting scientists. Crude oil can exist either
deep down in the earth's surface or deep below the ocean beds.
14. • Saudi Arabia, USA, Russia, China and Iran are among the top crude oil
producers in the world, and the USA is the world's biggest consumer of
crude oil, followed by China.
• A great chunk of all the total crude oil in the world is processed as gasoline,
which we use for our cars.
15. What is natural gas?
• Natural Gas is colorless, shapeless, and odorless in its pure form. Unlike
other fossil fuels, natural gas is clean burning and emits lower levels of
potentially harmful byproducts into the air. It is therefore called "Clean
Gas'.
• Natural gas supplies about 23.8 percent of the world's energy. Gas is
extracted by drilling wells deep into the ground, through many layers or
rock to reach the gas deposits.
16. What is Uranium (Nuclear Energy)?
• Nuclear energy is energy in the nucleus (core) of an atom. Atoms are tiny
particles that make up every object in the universe. There is enormous
energy in the bonds that hold atoms together.
• It is usually in a form of heavy metal, naturally occurring in most rocks,
soil, and even in the ocean! It is found in many places in the world. Energy
from uranium is called nuclear energy.
17. Facts
• In 2011, a tsunami struck Japan and caused problems with its nuclear
power plant in Fukushima.
• There are laws that check that countries with nuclear plants comply with
safety rules and also do not misuse their plants for developing nuclear
weapons.
