Most candidates could describe features present or not visible in the image which would facilitate the success of the wind farm such as it being hilly, windy, away from settlement and a large site. A few referred to there being no birds despite the possibility of them flying into the area and possibly into the turbines.
— Examiner report, May/June 2025, 0680/23 Q3(b)(v) (Cambridge)
The majority of candidates’ understanding was limited to turbines being rotated or moved by the wind. The need to translate this motion or kinetic energy into electrical energy was included only by the more able candidates who mentioned the rotating of the generator and the use of gears. A great proportion of candidates used the term ‘mechanical’ energy instead of kinetic energy which did not scor...
