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
Energy from unstable atoms such as uranium
The atoms give off heat, used to create steam to turn a turbine
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
