Geo 101 While the Earth travels through Space…..
Geo 101 …it absorbs Energy from the Sun
Geo 101 This natural Energy Collection and Storage System captures nearly half of the Solar Energy falling on Earth… …thus maintaining a nearly Constant Temperature throughout the year just below the surface
Geo 101 Water is an incredibly efficient medium for transporting Thermal Energy
Geo 101 • Earth Energy ….It’s not New • Earth Energy System was Patented in 1912 in Switzerland • Residential System installed in Canada in 1950
Geo 101 Heat Pumps Systems are Reliable Mr. Bill Loosley installed geothermal system in his home in Burlington, ON in 1950
Geo 101 Compressor was initially powered by hand crank diesel motor… changed to electric motor (still being used!!) in 1953 when his wife couldn’t start it Heat Pump Systems are Reliable
Geo 101 Geothermal Heat Pump Systems combine Sun, Earth and Water using proven technology… … to create “the most energy-efficient, environmentally clean, and cost-effective space-conditioning system” (according to U.S. EPA 1993)
Geothermal Heat Pump Efficiency One unit of energy from the grid Yields: 4-6 units of energy for the building Plus: 3-5 units of energy from the earth 400-600% Efficient
Geothermal Heat Pumps are the Most Efficient way to convert Green Energy into Heating, Cooling and Water Heating Making the most effective use of this precious resource
Geothermal Systems can be Classified as: Solar Geothermal Renewable Alternative Demand-Side Conservation Energy-Efficiency Zero-Ozone Depleting Environmentally Responsible
Geothermal Heat Pump Advantages
No Fossil Fuel • Improves safety • Eliminates service lines, flues, outside air intakes • No site emissions • No Outdoor Units • Better aesthetics • No noise • No vandalism or theft concerns • Long Equipment Life • Factory sealed systems • Indoor installation – no exposure to the elements • Moderate compressor loading vs. air-source systems • Self Contained Compact Units • Easy to install within the building • Upflow, horizontal, or downflow single-package units • Split system and water-to-water units available
Geothermal systems are at work in thousands of buildings throughout the world The Oklahoma State Capitol uses over 600 geothermal heat pumps
The payback on Geothermal Systems is many times faster than solar PV
Our Planet is under Assault from many Forces
43% of U.S. Carbon Emissions 39% of U.S. Primary Energy Consumption Industry 377 MMTC (25%) Buildings 658 MMTC (43%) Transportation 482 MMTC (32%) 71% of U.S. Electricity Global Pressures 53% of U.S. Natural Gas 1970-2020 (Exxon Mobile Projection) Buildings are the Major Contributor
Geothermal Heat Pumps are one of the Most Effective and Deployable and… … produce the lowest carbon dioxide emissions, including all source effects, of all available space-conditioning technologies(EPA, 1993)
Using a Single Geothermal Heat Pump is Equivalent to Planting an Acre of Trees
Using A Single Geothermal Heat Pump Is Equivalent to Taking Two Cars off the Road
Since their introduction in the 1980’s, nearly 1 million Geothermal Heat Pumps have been installed in the United States This is the equivalent to planting 1 million acres of trees, and of taking Two Million cars off the road
