The Great Earth Engine – Geothermal Energy for the USA

Reprint of article I wrote for Natural Awakenings Magazine

“When people think of renewable energy, their first thought is typically solar power or wind energy. As snowbirds return to their cooler climates, one natural and reliable renewable energy system is a geothermal or a ground-source heating and cooling system. These systems come with a variety of configurations, and a single system can heat or cool a home without natural gas, coal, oil or biomass. However, some electric power is required to run the system. This relatively obscure technology is robust, proven and available now to those willing to understand the simple beauty of these systems.

A geothermal system moves and stores energy rather than producing energy through combustion or resistance. Geothermal systems work by exchanging hot or cold air from the home with the stable stored energy in the ground, rather than by converting chemical energy to heat. This is a renewable energy system that is very efficient and has enough flexibility to fit a variety of applications. Some added benefits in addition to efficiency are that geothermal energy creates no pollution to our air or water and, other than electricity, they eliminate the need to purchase highly processed petrochemical fuel from less than environmentally conscious producers.

While the air temperature in northern climates can vary from season to season, the Earth’s temperature a few feet under the surface is essentially the same in winter and summer. In the winter, the system can heat a home using the Earth’s relatively warm core energy. In the summer, the same system can cool the home with the Earth’s relatively cool mass. Year-round, geothermal systems can produce hot water.

Geothermal heat pumps have an efficiency of over 300 to 500 percent (meaning they get a payback of three to five times the energy used to run the system). This efficiency  provides the heating/cooling needs at a cost that is 30 to 70 percent less expensive than conventional energy systems, without combustion, carbon dioxide, methane, water pollution or the waste generated by other energy systems.

Geothermal ground-source heating and cooling systems work during the night, when the sun is blocked by clouds and when the wind is not blowing. While electricity costs may vary, geothermal costs don’t fluctuate like natural firewood, gas, coal and heating oil. The ground-source system comes in a variety of configurations to easily fit new home construction or homes with a more conventional, existing duct-based heating and cooling system.


The geothermal system has three main components: connection to the Earth, delivery and distribution system and a geothermal heat pump. The Earth connection allows the system to pull or store heat in the Earth. In heating mode, the system uses the Earth connection to pull a small quantity of heat from the Earth to heat a person’s space. In cooling mode, the system does the reverse and transfers heat from the air back to the Earth. The distribution system can be a series of vertical connections or loops buried in the ground that transfer and help to distribute the energy.

The geothermal heat pump is very efficient energy transfer system that moves the energy from the building to the transfer fluid. The system does require an electrical source to run the heat pumps and circulation system, and it is critical that an existing home have a formal energy audit done prior to installing a system.

New construction should use green building and energy efficient insulating systems so the system can be properly sized.

Users can benefit from lower energy costs, elimination of water and air pollution and a significant reduction of the expensive and environmentally destructive infrastructure of fossil fuels by adapting geothermal systems as soon as possible. ”

Participated in Jessup Panel Discussion on Invenergy

Participated in a Panel Discussion at the request of Representative Frank Farina – I have not worked on the Invenergy Project and I was requested to be available to answer questions related to geology, hydrogeology, water quality, regulatory process, environmental impacts, stormwater issues, and stream related matters.  Prior to attending the event, I visited the site and reviewed the available soils, geologic, and water quality data.  I attended the panel discussion with Q/A – a link to a series can be found at the following webportal.  I strongly suggest you watch video 6.

During the Panel discussion the following questions were raised

1. How are discharge limits sets?   The PADEP set the discharge limits for a facility based on the average and peak discharge flow, existing stream quality, existing stream flow, classification of the stream, and the nature of downgradient users.

2. Have the discharge limits been set? No -the discharge limits have not been set for the stream and the peak flow is 600,000 gpd and a potential average flow is 400,000 gpd.

3. Will the discharge adversely impact the stream?  The process the PADEP uses is designed to have no adverse impact on the stream.  The PADEP will set discharge limits to prevent and adverse impact on the stream or no impact on the stream depending on the stream quality and classification.   For this project, a critical design parameter will be temperature and most likely the design of the outlet structure.

4. What chemicals will be used in the water treatment process?  This can not be known until the PADEP sets the limits.  The PADEP has a list of allowed chemicals that could be used and are pre-approved.  The list is here.   Note:  This is a list of all the chemicals PADEP has approved for a variety of processes and projects and NOT This Project.  This list is not project or site specific.

5. Is it possible that PADEP may set limits that are not attainable?  This should not happen, but it may.

6. Limits are set via a NPDES permit process?  This process will likely require daily monitoring of the treatment process (incoming water, within process, discharge water) – Certified water testing on a monthly basis – continuous flow monitoring and most likely consist monitoring of pH, temperature, conductivity, and oxygen.  The monitoring program will likely include upstream and downstream monitoring of water quality and maybe flow.

7. Water Withdrawal ?  Is there enough water ?   It appears that the water company has been allocated sufficient water for the area.  The allocation process is controlled by the SRBC (Susquehanna River Basin Commission).  They regulate the initial water allocation, create a docket, and would have to approve any docket modifications.  This may be a docket modification by the SRBC.  This would be an excellent time to put in-place in-stream water quality monitoring for the watershed.  It was suggested that in-stream monitoring with a web-portal to access daily was being considered.

8. In a drought what happens?  SRBC controls allocation via the docket – plant would have to apply to provisions.  If this means going off line to meet requirements – this is what would have to happen.  The plant could attempt to develop some backup or supplemental sources.

9. Geology for the area ? Any issues ?  There does appear to be some historic strip mining and soil mapping suggests some urban dumping.  The bedrock is typical of the Llewellyn  Formation (coal bearing formation) and the Pottsville Formation (sandstone).   The area has no mapped sinkholes, faults, or known geologic hazards.

In Video 6 – I had to interpret a question because what the person was doing was not asking a question but making a statement that was not true and correct.  For the record,

1. I have never sponsored an oil and gas energy event.
2. I have never sponsored an energy event dinner.
3. I did not attend the event in question, but I did get a free invitation to the event because I subscribe to an online newsletter about environmental and oil and gas issues through out the US.  This free invitation was to the event only and I would have to pay for lunch.  I did register, but I did not attend the event.
4. Rather than attending the event, I helped the DCNR with a program that was scheduled for the Tues before and Thursday after on environmental issues with natural gas development, but because a tour for a drilling site could not be set-up we did a tour and water testing of a salt water spring in Susquehanna County, PA.
5. As a fallout of the tour- we are in the process of raising funds to help purchase 3-Phosphate testing meters for the DCNR Program – estimated cost $ 2000.00.  Send donations via this portal.  The next $ 2K raised will go to buying the water quality meters.
