Future Champions (Ages 11-14) | Energy Revolution
When you're driving in 2050 (at 38), your car will be electric. Here's why.
HOW EVs WORK
- Battery: Stores electricity (lithium-ion)
- Electric motor: Converts electricity → rotation
- Inverter: Converts DC (battery) → AC (motor)
- Controller: Manages power flow
No engine, no transmission, no exhaust!
EVS VS GAS CARS
Efficiency:
- Gas car: 20-30% efficient (70% wasted as heat!)
- EV: 85-90% efficient
Maintenance:
- Gas: Oil changes, spark plugs, exhaust, transmission
- EV: Brake pads, tires, wiper fluid (THAT'S IT!)
Cost:
- Gas: €0.12/km
- EV: €0.03/km (75% cheaper!)
BATTERY TECH
- 2010: 100 Wh/kg, $1,000/kWh
- 2025: 250 Wh/kg, $150/kWh
- 2030: 400 Wh/kg, $75/kWh projected
Range anxiety ending: Many EVs now 400-600 km range!
CHARGING
- Level 1: Home outlet, slow (16 hours)
- Level 2: Home charger, medium (4-8 hours)
- Level 3 (DC fast): Public, fast (20-30 min to 80%)
ENVIRONMENTAL TRUTH
"EVs just move pollution to power plant!" - Debunked:
- Even coal-powered EV cleaner than gas car
- With clean grid: 80-90% cleaner!
- Battery recycling improving (95% recyclable)
ACTIVITIES
- Test drive EV (Tesla, local dealers offer)
- Calculate total cost: EV vs gas over 10 years
- Map charging stations in your area
