renewable energy

Question 1

what is electricity, and how is it generated?

Answer 1

electricity is generated from an original source, such as the sun, chemical, or movement

Question 2

what is electrical energy?

Answer 2

electrical energy is distributed through power lines and originates from electricity.

Question 3

define renewable energy sources

Answer 3

renewable energy sources are sustainable, meaning they will never run out and can be used to generate electricity forever

Question 4

define non-renewable energy sources

Answer 4

non-renewable energy sources are non-sustainable, meaning the resources needed are limited and will eventually run out

Question 5

how is electricity generated through hydroelectricity?

Answer 5

water falls over a dam, moving large generators that produce electricity

Question 6

how does solar energy work?

Answer 6

the sun shines on a photovoltaic cell, which converts light into electricity

Question 7

how does wind energy generate electricity?

Answer 7

wind blows, turning a large fan turbine that powers an electrical generator

Question 8

what is biomass energy

Answer 8

biomass is plant-based material burned to produce heat or electricity

Question 9

how does geothermal energy work?

Answer 9

steam from deep in earths core turns a turbine which activates a generator and produces electricity

Question 10

what is tidal energy?

Answer 10

as tidal water rises and falls, it turns a turbine to generate electricity. this can only occur in oceans with significant tides

Question 11

how do fossil fuels generate electricity?

Answer 11

a substance like oil, natural gas, or coal is burned to heat water. the resulting steam drives electricity to generators.

Question 12

how is electricity generated through nuclear power?

Answer 12

uranium atoms split releasing heat. the heat boils water, and the steam drives electrical generators.
