Future Champions (Ages 11-14) | Energy Revolution
In 2050 (when you’re 38), solar will power YOUR world. Here’s how it works.
PHOTOVOLTAIC EFFECT
Solar panel = semiconductor (silicon) + sunlight = electricity!
Process:
- Photon (light particle) hits silicon
- Knocks electron loose
- Electron flows = electricity!
- Collected by metal contacts
No moving parts. No fuel. Just light → electricity!
PANEL ANATOMY
- Front: Glass (protects, transparent)
- Silicon cells: Where magic happens
- Back sheet: Protects from weather
- Frame: Aluminum structure
- Junction box: Connects to wires
SOLAR EFFICIENCY
- 1950s: 6% efficient
- 2025: 20-22% commercial, 26% lab
- 2050 goal: 30%+ (perovskite, tandem cells)
Every 1% efficiency gain = billions in energy
ECONOMICS
- 2010: $1.00/watt
- 2025: $0.30/watt (70% drop!)
- 2030: $0.20/watt projected
Solar now CHEAPEST electricity in history!
YOUR 2050 SOLAR CAREER
- Solar installer: $45K-65K
- Solar engineer: $70K-100K
- Solar project manager: $80K-120K Massive job growth!
ACTIVITIES
- Build mini solar USB charger (kit $15-30)
- Calculate your home’s solar potential (PVWatts calculator)
- Visit solar installation or farm (many offer tours)
