Renewable And Non-Renewable Energy Flashcards
List the non-renewable energy sources ? (fossil fuels)
Oil, gas, coal
List the renewable energy sources
- wind
- solar
- biomass
- geothermal
- tidal
- hydro-electric
How does biomass produce electricity?
Produces electricity by burning waste and wood.
How does wind power produce electricity?
Produces electricity when blades are rotated by the wind.
How does solar power produce electricity?
Produces electricity from the sun.
How does wave power produce electricity?
Produces electricity from the movement of waves.
How does geothermal power produce electricity?
Produces electricity from heat energy from the Earth.
What are the disadvantages of biomass?
- smelly
- releases CO2 when burnt
- some waste releases harmful gases when burnt
Advantages of biomass?
- renewable
- saves some waste from landfill
Disadvantages of wind power ?
- weather dependent
- may never generate enough energy to replace the energy used to make them
- can disrupt local wildlife
Advantages if wind power?
- free energy once installed
- no pollution
- needs no energy to work
Disadvantages of solar power ?
- expensive to make and install
- weather dependent
- needs consistent cleaning
Advantages of solar power ?
- free nervy once infrastructure in place
- no pollution
- doesn’t need fuel to work
Disadvantages of wave/tidal power?
- current designs not energy efficient
- energy produced is dependent on size of waves
- next to be able to withstand extreme weather conditions
Advantages if wave/tidal power?
- renewable
- free energy once infrastructure installed
- low cost maintenance
