- 1. Geothermal Energy for Ponca City Speaker's Bureau What We & You Can Do Now Ponca City Development Authority
- 2. What is Geothermal Energy?
- 5. Source of Geothermal Energy:
- 6. … one method for capturing geothermal energy is through the use of Geothermal Heat Pumps…
- 10. Geothermal Heat Pumps are one of the Most Effective & Deployable Methods of Energy Transfer According to the EPA (1993), geothermal heat pumps produce the lowest CO 2 emissions, including all source effects, of all available space-conditioning technologies.
- 11. Heat Pumps Are All Around Us… Air conditioners & air-source heat pumps transfer heat from inside houses to the air outside Refrigerators transfer heat from food into the kitchen HEAT HEAT
- 13. … using Heat Pump Technology A geothermal heat pump circulates water through a sealed underground piping loop where it is naturally warmed (or cooled) by the earth
- 14. The Earth is the Source of Heat in Winter… Outdoor air design temperature: -5°F 72°F 60°F A geothermal heat pump transfers underground heat into the building to provide heating
- 15. … and an Efficient Place to Reject or Store Heat in Summer… Outdoor air design temperature: 95°F 75°F 60°F A geothermal heat pump transfers heat from the building into the ground to provide cooling
- 17. Geothermal Heat Pump Historical ARI GSHP Shipments 1983 - 2007 50,000 25,000 0 1983 2007 3 2 2004
- 22. Energy Issues:
- 23. Geothermal Heat Pump Industry Opportunity: Significantly Lower U.S. Energy Demand
- 24. “ Built Environment” HVAC: = 70% of all electric energy consumed Idaho Energy National Lab Residential + Commercial + Institutional
- 26. HVAC Energy Use Comparisons Reduces energy consumption by 50%: Conventional HVAC - Home Geothermal HVAC - Home
- 27. Geothermal Heat Pump Efficiency: 1 unit of energy from the grid Plus: 3-5 units of “free” energy from the earth Yields: 4-6 units of energy for the building 400 - 600% Efficient
- 30. Incentives
- 35. Value of Residential Incentives in Ponca City: Element $/ton capacity Ground Source Heat Pump Installation ~$6,000 30% Federal Tax Credit ($1,800) PUCA/OMPA W.I.S.E. Rebate ($800) PCUA/OMPA OK Comfort Program ($1000) Climate Master Discount (5-10%) estimate ($300) Total Reductions $ % ($3900) 65% Your Cost $ % $2100 35% Typical Energy Bill Reduction 50%

- 8 Everyone here has at least one heat pump in their home right now…the fridge. You cannot make cold, all you can do is remove heat. They take heat inside and near zero and pump it to heat exchange coils on bottom or in the back that are much warmer than the temperature inside it AC is also same technology
- 8 We typically use a closed sealed piping loop to circulate water, or in cold climates a water/anti-freeze mixure, to extract heat from the earth We use heat pump technology to move the heat and elevate its temperature
- 8 Why should we utilize high quality fossil fuels that are a mobile fuel capable of burning at thousands degree just to heat a building to a low temperature barely above that in the earth right below it? This is like making electrical wire out of silver instead of copper… it works great but is a waste of a precious resource Compare the earth temperature to the outside air temperature
- 8 Compare outside air to earth temperature and note how much higher cooling efficiencies can be when you are not working to pump the heat to a hot place
- 8 Growth of industry over years since we began keeping records. Drop in early 80s due to loss of the original tax credit that launched our industry. Estimated 20,000 jobs exist today in GHP because we had that tax incentive that birthed our industry. Without it, I doubt GHP would exist today, surely not at this scale Growth from mid 80s to mid 90s due to utility demand side management and energy efficiency program support of GHPs and Clinton/Gore funding of GHP market transformation program Utilities dropped demand side activities due to deregulation in mid 90s… energy was still cheap and we fell on hard times as an industry Post 911 and Katrina with gas cost spike, GHP sales have doubled in just a few years. BIG POINT: In 2007 one of every 70 new SF homes built in the US installed a GHP. There is no other renewable even close… and we have huge potential to get the other 69 of 70 still ahead of us
