East Kentucky Power Cooperative January 20, 2011 McNabb Middle School Slide 2 Electricity A secondary energy source, also referred to as an energy carrier Created from the conversion of other sources; these sources can be categorized two ways Can you name the two types of sources?? Slide 3 1. Non-renewable forms of energy Fossil Fuels--Power plants burn fossil fuels to create electricity. Nuclear Power--Atoms are split, which heats water to create steam that turns a turbine to create electricity. Slide 4 2. Renewable forms of energy Slide 5 Slide 6 EKPCs Sources of Electricity Total MW capacity Percent of capacity MW hours in 2009 Percent of MW hours Coal1,93364.6%10,636,00097.4% Natural gas1,042 Winter net 34.8%192,0001.8% Landfill gas14.40.6%96,3930.9% 6 Slide 7 East Kentucky Power Cooperative 1. 1,346 MW Spurlock DaleSmith Cooper 2. 195 MW 3. 786 MW SUMMER 1,016 MW WINTER 4. 341 MW Slide 8 Fuel is burned in boiler to produce steam. Steam turns mechanical turbine connected to generator. As turbine rotates, turns magnetic field inside generator to produce electricity. Steam leaves turbine and goes to condenser. Water from nearby source cools steam back to water. How We Make Electricity Slide 9 Benefits of using Coal and Fossil Fuels? in Kentucky? Slide 10 Reasons to investigate alternatives to fossil fuels? Slide 11 Renewable Energy in Kentucky Slide 12 Renewable Energy in Kentucky Wind Resources Slide 13 Black Mountain Renewable Energy in Kentucky In Kentucky the higher the elevation, the better the wind resources Slide 14 Wind Resources Needed to Operate: 1.8 kW @ 22 MPH optimum 8 MPH to release the brake Cost - $13,000-$15,000 installed Renewable Energy in Kentucky Residential Units Skystream 3.7 Slide 15 Slide 16 Renewable Energy for Kentucky Solar Power - Photovoltaic Photovoltaic Panels 200 watt Cost = $1,100 per panel plus installation 10 panels generate 2 kW of electricity Total cost of system = $19,000 installed Does NOT include battery backup ! Slide 17 Renewable Energy for Kentucky Solar Power Photovoltaic Average Sunlight Hours Each Day Jan 3.1 Feb 3.8 Mar 4.4 Apr 5.1 May 5.4 June 5.6 July 5.5 Aug 5.5 Sept 5.1 Oct 4.6 Nov 3.2 Dec 2.7 Average for Kentucky 4.5 Average for Florida 5.3 http://rredc.nrel.gov/solar/pubs/redbook/ Renewable Resource Data Center (RReDC) Ave cost of power in Ky 7.2 cents Ave cost of power in Fla 11.2 cents Slide 18 Renewable Energy for Kentucky Solar Power Photovoltaic Do the Math For example: Solar in Kentucky 4.5 hours of sunlight x 2 kW = 9.0 kWh per day 9.0 kWh/day x 30 days = 270 kWh/month Slide 19 Renewable Energy for Kentucky Solar Power Photovoltaic Do the Math @ $.08 kWh Cost of Unit: $19,000- $5,700 tax credit Net Cost = $13,300 Savings/Year at $.08 = 270 *$.08 * 12 = $259.20/yr $13,300/$259.20 = 51.3 years Payback at $.08 = 51 years Slide 20 Renewable Energy for Kentucky Solar Power Photovoltaic Do the Math @ $.12 kWh Cost of Unit: $19,000- $5,700 tax credit Net Cost = $13,300 Savings/year at $.12 = 270 *$.12 * 12 = $388.8/yr $13,300/$388.8 = 34.2 years Payback at $.12 = 34 years Slide 21 Renewable Energy for Kentucky Solar Power Photovoltaic Do the Math @ $.16 kWh Cost of Unit: $19,000- $5,700 tax credit Net Cost = $13,300 Savings/Month at $.16 = 270 *$.16 * 12 = $518.40/yr $13,300/$518.40 = 25.6 years Payback at $.16 = 25 years Slide 22 Renewable Energy for Kentucky Solar Power Photovoltaic Do the Math @ $.25 kWh Cost of Unit: $19,000- $5,700 tax credit Net Cost = $13,300 Savings/Month at $.25 = 270 *$.25 * 12 = $810/yr $13,300/$810 = 16.4 years Payback at $.25 = 16 years Slide 23 Using an average of 1900 KwH a month. Electric panels, plus battery backup, is about $17,500 for every 270 kWh 1900 kWh / 270 kWh * $17,500 = $123,148 Finance $123,148 for *15 years at 6% = $1,039 per month *15 years is the estimated battery life. 1900 KwH bill pays an average of $.08 per kWh per month 1900 kWh * $.08 = $152 per month Cost Converting home to Solar 100 % Photovoltaic Slide 24 Solar Water Heaters Slide 25 How Do They Work? Slide 26 Typical Unit for family of 4 = $5500 installed After 30% federal tax incentive = $3850 After $500 Kentucky State Rebate = $3350 Energy usage = 12 kWh per day or 360 kWh per month 50% solar fraction = 180 kWh per month savings 180 kWh *$.08 per kWh * 12 months = $172.80 per year $3,350/$172.80 per year = 19.4 years Payback is 19 years Cost of Solar Water Heater @ 50% Energy Savings @ $.08 per kWh Slide 27 Typical Unit for family of 4 = $5500 installed After 30% federal tax incentive = $3850 After $500 Kentucky State Rebate = $3350 Energy usage = 12 kWh per day or 360 kWh per month 75% solar fraction = 270 kWh per month savings 270 kWh *$.12 per kWh * 12 = $388.80 $3,350/$388.80 per year = 8.6 years Payback is 9 years Cost of Solar Water Heater @ 75% Energy Savings @$.12 per kWh Slide 28 Slide 29 Landfill Gas to Electricity Slide 30 Slide 31 Renewable Energy - Biomass Slide 32 Landfill Gas to Electricity Landfill Gas is extracted using a series of collection wells.. Slide 33 Landfill Gas to Electricity Cat 3516 LE Engine/Gensets ..The landfill gas is used as fuel to spin reciprocating engines and produce electricity 24/7. Slide 34 Slide 35 Why Green Power? Total Equivalent Emissions Reduced: 29,881 tons of methane per year 85,443 tons of carbon dioxide per year Slide 36 Green Power in Kentucky 17 megawatts of electricity = 10,000 homes in Kentucky I million tons of MSW=.8 megawatt of electricity 432,000 cubic feet per day of LFG Bavarian= 660 acres, 4.58 million tons of trash in place Slide 37 Doing inventory after 10 years... Photos by Dr. Riley Kinman, Ph.D., University of Cincinnati Slide 38 Why renewable energy alternatives? Slide 39 Why resist renewable energy? Rising Costs Slide 40 Slide 41 Conserve Energy Recycle Change Habits Ways to Go Green Slide 42 Slide 43 How can you save energy at home? How can you save energy at school? Slide 44 Slide 45 Save Energy Programmable Thermostat 12% energy savings Adjust thermostat up 2 degrees in summer; down 2 in winter- save $45 a year HVAC system professionally inspected can save $50 a year Clean or replace furnace filters every 30 days Slide 46 Recycling one aluminum can saves enough energy to keep a 100-watt bulb burning for almost 4 hours or run your television for 3 hours Tossing away an aluminum can wastes as much energy as pouring out half of that cans volume of gasoline Slide 47 Americas plastic bag makers have committed to achieve a goal of 40 percent recycled content, including 25 percent post-consumer material, in all plastic shopping bags by 2015. This will reduce greenhouse gas emissions by 463 million pounds, conserve enough energy (mainly natural gas) to heat 200,000 homes and reduce waste by 300 million pounds annually. It takes 91 percent less energy to recycle a pound of plastic than it takes to recycle a pound of paper. Consider that countless bags end up in the ocean where marine life can mistake them for food. A wandering grocery bag looks suspiciously like a jellyfish, the main food source for many turtles. Slide 48 Slide 49
