Sources of Energy

Electrical sources can be broken down into THREE major groups

• True

• False

Energy resources which naturally renew or replenish themselves over a period of time

• renewable resources

• non-renewable resources

• reduce, reuse, recycle

• solar resource

Energy from deep within the Earth

• solar

• magma

• geothermal

• biomass

Hydroelectric power produces electricity using

• moving water

• wind

• dung

• sunlight

Energy from any material that comes from plants of dead organisms is called

• fossil fuels

• hydroelectric

• geothermal

• biomass

Which of the following is NOT an advantage of using hydroelectrical energy?

• dams are expensive to build

• creates no green house gases

• energy is inexpensive to harness

• energy from water is free and reliable

Which of the following is NOT an advantage of using wind energy?

• renewable source of energy

• one of the most cost effective source of electricity

• energy is inexpensive to harness

• reliant on weather and therefore cannot produce electricity 24/7

Solar, wind, hydoelectric, geothermal and biomass are all

• renewable sources

• natural resources

• non renewable resources

Which of the following answer choices are true about renewable resources

• wind, solar and hydroelectric energy using the same type of equipment

• produces too much green house gases

• biomass is non-renewable because of dead organisms

• equipment use to harness energy from renewable resources are expensive to build

Nonrenewable resources are natural resources, such as fossil fuels and electrochemical (batteries), that will eventually used up and can never be replaced

• false

• true
