Remewable And Non Renewable Flashcards
What are renewable sources
Sources that can be replaced and once used can be used again
What are the 6 main renewable sources
Wave,tidal,biomass,wind,solar,hydro
How is wind energy formed
Kinetic energy of the wind can be used
To
Generate energy using wind turbines
How is tidal energy formed
Kinetic energy of the tide can be used to generate electricity using turbines under the water
How is wind energy
Formed
Energy
From natural water movement converted into
Rotational
Motion that generates electricity
Pros
And
Cons of water/tidal energy
Doesn’t produce harmful gasses or pollutions but doesn’t have much electricity and can effect wildlife and shipping
What is hydroelectric energy
Water kept
High on a dam is released and flows down pipes on a steep hill to turn turbines
What is solar energy
Energy from Sun heats water into Steam generating electricity and can also be used directly Into Energy
Pros
And
Cons of
Solar energy
No harmful gasses or
Pollutions,renewable,free heat but it takes up
A lot
Of space and requires sunlight and is expensive
What is biothermal
Plant material that is burned to
Produce electricity
Pros
And
Cons of biothermal
Produces less
Co2 than fossil fuels but still produces co2 needs large area t grow
What is geothermal
Heat from
Earth to heat water this can be tit
What are non renewable sources
Sources that cannot be replaced and once used cannot be used again
Pros an cons of
Geothermal
No chemicals or Pollutants free Renewable but can only be in certain locations where rocks Are Close to Surface
What is fossil
Fuels
Power
Stations burn oil,gas,oil to heat water In a boiler
