Module 1.0: Power and Energy Sources 1

Question 1

is a scalar quantity whose SI unit is Joule.

Answer 1

Energy

Question 2

The energy in motion is known

Answer 2

Kinetic Energy

Question 2

This is the energy stored in an object and is measured by the amount of work done.

Answer 2

Potential Energy

Question 3

It is the sum of potential energy and kinetic energy that is the energy associated with the motion & the position of an object.

Answer 3

Mechanical Energy

Question 4

is stored in a chemical substance in between the bonds of atoms in compounds.

Answer 4

Chemical Energy

Question 5

is the power an atom’s charged particles have to cause an action or move an object.

Answer 5

Electrical Energy

Question 6

is one that can be used repeatedly and does not run out because it is naturally replaced.

Answer 6

Renewable Resource

Question 7

is the energy of the sun that’s collected by solar panels and then generated into electricity.

Answer 7

Solar Energy

Question 8

The whole idea around this phenomenon is to use the power of the wind to launch and turn large wind turbines that will power up the generator and create electricity.

Answer 8

Wind Energy

Question 9

is sustainable power created inside the ground we are walking on.

Answer 9

Geothermal Energy

Question 10

generates electricity from flowing water using turbines and other devices. It’s renewable and can be generated from rivers or manmade installations.

Answer 10

Hydroelectric Energy

Question 11

two-thirds of water’s chemical construction is this element. It can be used as a fuel that will generate electricity if it gets separated from other elements.

Answer 11

Hydrogen Energy

Question 12

It is based on kinetic energy that follows incoming and outgoing tides that are converted into electrical energy.

Answer 12

Tidal and Wave Energy

Question 13

The whole process is based on burning biomass materials in a combustor or furnace, which will produce hot gas. Then, that gas goes into a boiler that will generate steam, which will be expanded by the steam engine in order to produce usable energy.

Answer 13

Biomass or Biofuel Energy

Question 14

referring to the coal, natural gas, and oil. These are the main sources of power in most
parts of the world.

Answer 14

Fossil Fuel

Question 15

generate power by converting the force of water to turn large generators.

Answer 15

Hydroelectric Power Plants

Question 16

This energy source uses naturally occurring radioactive material. Usually, uranium is manufactured into fuel rods for nuclear reactors.

Answer 16

Nuclear Energy

Question 17

A type of hydroelectric power plant that uses a store of
river water from a dam in a reservoir. When water is released from the reservoir, it flows through a turbine which generates motion. This turning motion activates a generator to produce electricity.

Answer 17

Impoundment Power Plant

Question 18

similar to an Impoundment facility, but may not need the use of a dam, but works by channeling a portion of a river through a canal or a penstock.

Answer 18

Diversion Power Plant

Question 19

stores its energy by pumping water uphill to a reservoir at a higher elevation.

Answer 19

Pumped Storage Power Plant

Question 20

generate electricity by converting heat into electricity, essentially by burning a fuel.

Answer 20

Thermal Power Plants

Question 21

uses reactors heat to turn water into steam. The steam is then sent through a turbine, which, as we’ve already learned, generates movement of a generator, which in turn generates electricity.

Answer 21

Nuclear Power Plants

Question 22

works in much the same way, but instead of a nuclear reactor heating water to make steam, the heat from the burning coal powers a steam turbine.

Answer 22

Coal Power Plant

Question 23

generate electricity by burning natural gas as their fuel.

Answer 23

Natural Gas Power Plant

Question 24

is essentially a heat exchanger, in which the hot gases boil pre heated water into steam. The steam then expands through a turbine, generating electricity. Once the steam has passed through, it condenses and is recycled through.

Answer 24

Heat Recovery Steam Generator (HRSG)

Question 25

This type of plant uses the suns energy to convert into electricity. This is achieved by using Photovoltaic, or PV panels, made up from a number of semiconductor cells that release electrons when they are warmed by the thermal energy of the sun.

Answer 25

Solar Power Plant

Question 26

get their energy from the wind by connecting a generator to the blades. The rotational movement of the blades caused by the wind, powers a generator.

Answer 26

Wind Power Plant / Wind Turbines

Question 27

This type of power plant is used for small-scale production of electric power. They are installed in places where there is no easy availability of alternative power sources and are mainly used as a backup for uninterrupted power supply whenever there are outages.

Answer 27

Diesel Power Plant

Question 28

They essentially work the same as a coal or nuclear power plant, the main difference being the heat source. With geothermal, the Earth’s heat replaces the boiler of a coal plant or the reactor of a nuclear plant.

Answer 28

Geothermal Power Plant
