2. LEDs make sense  Convert half of the 410,000 households in RI to LEDs  Assume 40 Bulbs per Household ave.  Estimated Energy Usage per month is 1,000 kwh  LEDs will reduce consumption by 25%  Energy reduction for state per month is 51,250,00 kwh  Cost savings per month for Customers is $8,700,000  Cost of Bulbs @ $10 ea. $82,000,000  Payback period 10 Months  Deep Water Wind increase cost per kwh$.17  Consumer Cost increase for Alternative Energy $8,712,500 2 1

3. LEDs make sense  Replace all the light bulbs in a Household to LED’s  Assume 40 Bulbs per Household ave.  Average energy use per month is 1,000 kwh  LED’s will reduce consumption by 25% or 250 kwh/month  This will reduce CO2 emissions by 205 Tons per month per household  This will also reduce the electric bill by $42.50 per month per household  Convert half of the 2,500,000 households in MA to LEDs  Energy reduction for state is 312,500,000 kwh per month  This will reduce CO2 emissions by 256,250 Tons per month  This will also reduce electric bills by $53,125,000 3 1

8. LEDs make sense  For RI the savings per month are $8,700,000 vs an increase in cost of 8,712,500 which is a differential of $17,412,500 or $85 per household per month.  For MA the savings per month are $53,125,000 vs an increase in cost of $43,750,000 which is a differential of $96,875,000 or $77.50 per household per month. 8 1
