Efficiency Energy for the Future 7 Virtues of a 15-Watt CFL (10,000 hour lifetime) Compared to Twelve 75-Watt Incandescent Bulbs uFirst Cost for 1 CFL or 10 Incandescent Bulbs about the same: $5.00 uElectricity consumption is very different: –75 Watts – 15 Watts = 60 Watts x 10,000 hours = 600 kWh uMoney Savings: –600 kWh x $.12 per kWh = $ uFuel Savings: –600 kWh x 10,000 Btu/kWh = 6 Million Btus or ~ 1 barrel of petroleum uFuel Savings Example (using energy equivalence) –At 25 mph = 1,000 miles or SFO to Denver, one-way –At 50 mph (a new hybrid) = 2,000 miles or SFO to Denver and return
