Power Stations
Facilities that convert primary energy (fossil fuels, nuclear) into secondary electricity through turbine-generator systems.
Formula
Thermal Efficiency (%) = (Useful Electrical Output ÷ Total Fuel Energy Input) × 100
Real World
Drax Power Station in Yorkshire, once the UK's largest coal plant, converted four of its six units to burn biomass, illustrating how power station infrastructure can be repurposed to reduce carbon emissions.
Exam Focus
For 'evaluate' questions, compare efficiency percentages and discuss energy losses — examiners expect specific figures, not vague statements.
