Solar energy is the renewable source on this sheet and fossil fuels are non-renewable, so the Year 11 resource list starts by separating what can be replaced from what cannot. Nuclear fission is the recorded energy process, and the key notes a carbon-free electricity benefit.
Key Takeaways
Solar is a renewable energy source (Q1).
Fossil fuels are non-renewable (Q2).
Q3 records nuclear fission as an energy process.

Section C: Numericals & Word Problems (3 Marks Each)
Apply the concepts to solve the problems. Show all working.
15.A wind turbine produces 2 kW of power for 5 hours. Using energy = power × time, calculate the energy generated in kWh.
16.A power station has an input power of 500 MW and a useful output power of 150 MW. Calculate its efficiency as a percentage.
17.A kettle uses 2000 W for 3 minutes. Using energy = power × time, calculate the energy used in joules.
18.A 60 W lamp is switched on for 2 hours. Using energy = power × time, calculate the energy used in kWh.
19.A car engine is 25% efficient. It produces 50 MJ of useful energy. Calculate the input energy and the wasted energy.
20.Sunlight delivers 1000 W to every square metre of ground. A solar panel of area 2 m² collects energy for 1 hour. Using energy = power × time, calculate the energy collected in joules.
