It is quite hilarious to have LED(Light emitting Diode) *ENERGY* under the umbrella of "Renewable Energy Sources."

How blindly and bluntly the syllabus has been organised. Anyway, perhaps energy consumption - in industries in general and houses and shops in particular - and its(energy's) efficient usage are what made the syllabus-maker add it in the energy portion.

However, it has nothing to do with renewable energy source.

P.S: The thing making me curious is the notion "i.e." after renewable. Confidence of the syllabus-maker is unmistakable.
