Energy Crisis and Alternative Energy Resource

Question 1

the power to do work

Answer 1

Energy

Question 2

those that cannot be replaced once they are used

Answer 2

EXHAUSTIBLE ENERGY

Question 3

deposits of coal, petroleum (oil), and natural gas found underground. When we use these fuels, we are actually using the sun’s energy that was stored in plants and animals millions of years ago.

Answer 3

fossil fuels

Question 4

two classifications of exhaustible energy sources

Answer 4

fossil fuels

nuclear fuels

Question 5

fossil fuels

Answer 5

• COAL. Solid, combustible (burnable) substance that is brown to black in color obtained through mining operations. Coal is the most abundant fossil fuel. Coal reserves could last 500 years at our present rate of use.
• OIL (PETROLEUM). Most common petroleum products are gasoline and diesel fuel. Many homes and large buildings use oil as an energy source for heating. These uses, plus its use in transportation, have made oil the world’s most important fuel.
• NATURAL GAS. Mixture of several types of gases: ethane, propane, butane and methane. Widely used for cooking and for heating homes.

Question 6

Nuclear Fuels

Answer 6

Uranium
Plutonium

Question 7

the most commonly used nuclear fuel. Uranium is a heavy substance that is found in many metal ores.

Answer 7

uranium

Question 8

another substance that can be used to power nuclear reactors. If the breeder reactor became widely used, the energy available from our uranium supplies would increase sharply.

Answer 8

plutonium

Question 9

Those that can be used indefinitely if they are properly managed and maintained. Wood and plants are renewable sources of energy.

Answer 9

renewable energy

Question 10

A mixture of nine-tenths unleaded gasoline and one-tenth ethyl alcohol. It is used as a substitute for gasoline in cars and trucks.

Answer 10

Gasohol

Question 11

a clean-burning liquid fuel. It can be made from natural gas and coal. These sources are non-renewable.

Answer 11

Methanol or Methyl Alcohol

Question 12

the process of obtaining energy from society’s waste products. There are many sources of waste biomass: food product waste, animal waste, paper, cardboard and wood.

Answer 12

Bioconversion
Biomass

Question 13

oldest sources of energy

Answer 13

wood

Question 14

INEXHAUSTIBLE ENERGY

Answer 14

Solar energy
Hydroelectric energy
Geothermal energy
Wind energy
Hydrogen energy
Tidal Energy
Wave energy

Question 15

Can be used directly or indirectly. It can provide both heating and electricity.

Answer 15

solar energy

Question 16

simply electrical energy produced from flowing water.

Answer 16

Hydroelectric energy

Question 17

Heat that is generated within the Earth. It is a renewable resource that can be harvested for human use. Magma heats nearby rocks and underground aquifers.

Answer 17

Geothermal energy

Question 18

Kinetic energy produced by the movement of air, able to be converted to mechanical power.

Answer 18

wind energy

Question 19

used as a clean-burning fuel, leading to fewer pollutants and a cleaner environment. We also use it for fuel cells. These are similar to batteries and are used to supply power to electric motors.

Answer 19

Hydrogen energy

Question 20

With the movement of the tides, we get tidal energy when the kinetic energy of the water movement converts into electrical energy.

Answer 20

Tidal energy

Question 21

an alternative energy source derived from waves as they move across the water. uses electricity generators placed on the ocean’s surface.

Answer 21

Wave energy
