P3- Energy resources Flashcards
3 fossil fuels
Coal, oil, gas
9 energy resources
Wind, solar, wave, tidal, hydroelectric, geothermal, biofuel, nuclear, fossil fuels
Biofuel energy resource
Definition and explanation
A fuel taken from living or recently living organisms
Chemical energy turned into thermal energy, used to create steam to turn a turbine
Biofuel Ads & Dis
Ad- Renewable, carbon-neutral
Dis- Large areas of land needed to grow enough trees
Nuclear energy resource
Definition and explanation
What are the 2 fuels?
Energy from unstable atoms such as uranium
The atoms give off heat, used to create steam to turn a turbine
Uranium or plutonium
Nuclear Ads and Dis
Ad- High energy density per kg of fuel, no CO2 produced
Dis- Non-renewable, produces nuclear waste
Wind power energy resource
Definition and explanation
Energy from the wind
Wind turns the blades round, turns the generator
Wind power Ads and Dis
Ads- renewable, no CO2 produced
Dis- Unreliable, eye sore
Wave power energy resource
Definition and explanation
Energy from sea waves
Movement of waves moves turbine and generates electricity
Wave power Ads and Dis
Ads- Renewable, no CO2 produced
Dis- Unreliable-needs waves, can be damaged by storms
Hydroelectric energy resource
Definition and explanation
Energy from rivers
Movement from flowing water through dams turns generators
Hydroelectric Ads and Dis
Ad- Renewable, no CO2 produced
Dis- Expensive to build a dam, damages local environment
Tidal energy resource
Definition and explanation
Energy from sea tides
At high tide, water trapped then released through turbines to generate electricity
Tidal Ads and Dis
Ads- Renewable, no CO2 produced
Dis- Expensive, can cause flooding
Solar energy resource
Definition and explanation
Energy from the Sun
Solar cells generate electricity using energy from the sun
