  1. Electric EnergyConsumption EES 205

  2. US Energy Consumption: 100 QBtu

  3. 30% of US Energy  Transportation

  4. 40% of US Energy  Electricity

  5. Electricity End Use

  6. Power & Energy 15 Watt bulb consumes 15 W of power continuously. 15 Watt bulb on for 1000 hours consumes 15 W x 1000 hours = 15,000 Wh of energy. 15,000 Wh x 0.001 kWh/Wh = 15 kWh kWh is the standard unit of electric energy.

  7. Electric Energy Cost We don’t pay for power. We pay for the electric energy that we consume. So, we pay for kWh. The cost of electric energy in CT is about 20 cents per kWh

  8. Electric Energy ($) The cost of running a 15 W bulb for 2000 hours: Energy = 15 W x 2000 hours = 30,000 Wh = 30,000 Wh x 0.001 kWh/ Wh = 30 kWh Cost = 30 kWh x 20 cents/kWh = $6

  9. Kill A Watt Meter This meter measures the energy (in kWh) consumed by appliances and electronics. These measurements can help you reduce your electric energy use. The device can help you “kill a watt”
