2. Power usage: Can you reduce it? 3. Objectives: Responsible power usage Measuring power usage Power saving campaign Reducing power usage at school Reducing power usage at home Studying water consumption in power plants 4. Turn Me Off!Work 5. Power usage Awareness-raising at home about power usage How can we reduce it? How much water is needed to produce power? 6. Power usage Study of our family's power bills 7. Wattmeter Measuring with wattmeters Power usage in Euros 8. Wattmeter Home installation Fluorescent ceiling lights 9. Wattmeter 10. Wattmeter Power usage of two fluorescent ceiling lights working during 8 hours/day for 1 month: 0.50 11. Wattmeter Measurement of the power usage of appliances on STAND BY 12. Wattmeter STAND BY: Power usage is up to 10% of the appliances usage Power consumed by a PC: 90 W Power consumed by a PC on STAND BY: 9 W 13. Turn Me Off! Our power saving campaign 14.
