Energy Generation and Storage
Comparing energy sources and storage choices using performance, location, reliability, environmental and whole-life evidence.
How to prepare for the GCSE Design and Technology written exam
Move from requirement to evidence, technical principle, comparison and justified decision. Use current board materials separately for the NEA and for full timed-paper rehearsal.
Core concepts
Concept 1
Energy sources include finite and renewable resources, but suitability depends on output, variability, location, infrastructure, emissions, waste and cost.
Exam cue: Compare options against the same use context and system boundary.
Concept 2
Storage separates generation from demand and is selected using capacity, power, response, efficiency, lifetime, mass, safety and material considerations.
Exam cue: Distinguish energy capacity from the rate at which energy is transferred.
Concept 3
A product's energy decision includes manufacture, use and end-of-life, not only the energy consumed during operation.
Exam cue: Use dated data for current energy mixes or technology performance.
Risk pitfalls and guardrails
Treating renewable as impact-free or continuously available.
Guardrail: Do not substitute one board's specialist route or current product claim for the multi-board core, and do not turn written process knowledge into NEA or practical submission material.
Confusing an energy store with an energy source.
Guardrail: Do not substitute one board's specialist route or current product claim for the multi-board core, and do not turn written process knowledge into NEA or practical submission material.
Comparing percentages or emissions figures with different boundaries.
Guardrail: Do not substitute one board's specialist route or current product claim for the multi-board core, and do not turn written process knowledge into NEA or practical submission material.
Memory anchors
Renewable source
An energy resource replenished on a human timescale when managed within its limits.
Non-renewable source
A finite energy resource depleted much faster than it is replenished.
Capacity
The total quantity of energy a storage system can hold under stated conditions.
Power
The rate at which energy is transferred.
System boundary
The processes included and excluded when measuring an impact.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
