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??

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.

4. 2. Renewable forms of energy

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

9. Benefits of using Coal and Fossil Fuels? in Kentucky?

10. Reasons to investigate alternatives to fossil fuels?

11. Renewable Energy in Kentucky

12. Renewable Energy in Kentucky Wind Resources

13. Black Mountain Renewable Energy in Kentucky In Kentucky – the higher the elevation, the better the wind resources

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

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 !

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

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

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

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

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

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

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

24. Solar Water Heaters

25. How Do They Work?

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

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

29. Landfill Gas to Electricity

31. Renewable Energy - Biomass

32. Landfill Gas to Electricity Landfill Gas is extracted using a series of collection wells…..

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….

35. Why Green Power? Total Equivalent Emissions Reduced: 29,881 tons of methane per year 85,443 tons of carbon dioxide per year

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

38. Why renewable energy alternatives?

39. Why resist renewable energy? Rising Costs

41. Conserve Energy Recycle Change Habits Ways to Go Green

43. How can you save energy at home? How can you save energy at school?

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

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 can’s volume of gasoline

47. America’s 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.
