-Prompt exacto: 

Realistic, elegant educational scene for a secondary-school textbook, 1920x1080.
  A bright modern classroom with diverse 13–14-year-old students using tablets
  and a large interactive screen. The screen shows clear, simple diagrams of
  energy transformations (light → heat, electrical energy → movement) and a
  PhET-like simulator UI with sliders and smooth graphs. On the left, a
  semi-transparent cutaway of an apartment building with icons for fridge,
  washing machine, heater, and an electricity meter connected by subtle glowing
  lines, representing energy flow and consumption. In the background, balanced
  references to renewable and non-renewable sources: rooftop solar panels,
  small wind turbines, and a distant silhouette of a gas plant, all in neutral,
  textbook style. Clean composition, professional educational tone, warm and
  soft lighting, calm palette (blues, greens, soft grays), high detail, sharp
  focus, scientifically accurate, no clutter, no text labels.
