renewable and non-renewable resources Flashcards
How does a wind turbine generate electricity?
Kinetic energy from wind → Mechanical energy in the turbine → Electrical energy in the generator.
How does hydroelectric power generate electricity?
Gravitational potential energy (water at height) → Kinetic energy (falling water) → Electrical energy (turbine & generator).
What energy transfers occur in geothermal power?
Thermal energy (hot rocks underground) → Kinetic energy (steam moving turbines) → Electrical energy.
How do solar heating systems work?
Light energy (from the Sun) → Thermal energy (water heating systems).
How do solar cells generate electricity?
Light energy → Electrical energy (via photovoltaic cells).
What energy transfers occur in fossil fuel power stations?
Chemical energy (fuel) → Thermal energy (burning fuel) → Kinetic energy (steam moving turbines) → Electrical energy.
What energy transfers occur in nuclear power stations?
Nuclear energy (from uranium/plutonium) → Thermal energy (nuclear fission) → Kinetic energy (steam moving turbines) → Electrical energy.
Give one advantage and one disadvantage of wind power.
✅ No pollution & renewable ❌ Unreliable (depends on wind speed).
Give one advantage and one disadvantage of hydroelectric power.
✅ No pollution & reliable ❌ Flooding destroys habitats.
Give one advantage and one disadvantage of geothermal energy.
✅ Reliable & low pollution ❌ Only available in certain locations.
Give one advantage and one disadvantage of solar heating/cells.
✅ No fuel cost & renewable ❌ Only works when sunny.
Give one advantage and one disadvantage of fossil fuels.
✅ Reliable & produces lots of energy ❌ Releases CO₂ (causes global warming).
Give one advantage and one disadvantage of nuclear power.
✅ No CO₂ emissions & lots of energy ❌ Produces dangerous radioactive waste.
Would you like me to simplify anything or add more details? 😊
