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. ”

Saving energy has become increasingly important, as recent research has made it clear that the world’s energy consumption is negatively impacting the environment and natural resources. Each day, we use energy to keep our homes comfortable, but there are some small changes that we can all make in order to reduce the amount of energy that we use. By following a few tips, you can reduce your energy consumption and environmental footprint.
Choose Energy-Efficient Lighting Options
When searching for energy-efficient lighting design options, there is a large selection available. Compact fluorescent bulbs are a great option, as they use up to 75% less energy than other choices, and they can also be used with dimmers and wall sconces. Compact fluorescent bulbs have a long life span, reducing your waste and saving money over the life of the bulb.
While choosing the right type of light is important for energy efficiency, you should also work on energy-saving activities at home. Keep notes near the light switches in each room to remind residents of all ages to turn off the lights when they leave a room. These simple reminders can also help your family to make positive, energy-saving decisions when they are outside of your home.

Use Solar Lighting
If you are looking for an energy-efficient way to power your home, investigate with an architect whether solar lighting may be able to work for you. Solar panels are made of solar cells that are arranged in grid-like patterns, and during the day, they collect sunlight and use it to create electricity. You’ll be producing your own power, so your energy bills will be dramatically lowered. However, not all buildings will be good candidates for using solar panels, so some architecture research will be needed before you can pursue this option.
Your solar energy system can also inspire others to begin producing energy, which can increase the total amount of renewable energy that is available. This makes solar energy a great way to make a difference, to improve the environment, and to become self-sufficient.

Improve Your HVAC Systems
When it comes to home climate control systems, many homeowners struggle to find a balance between comfort and energy efficiency. During the summer, you may be tempted to turn on the air conditioner immediately, but a few tips can actually help before you resort to this method. If it isn’t too warm, open the windows and let some fresh air into your home. However, if it is hot, keep the shades drawn and use fans to circulate air throughout your home.
During cooler winter months, wear additional layers to keep warm, and set your thermostat a few degrees cooler. Reduce the heat while you are out of the house or asleep, and turn it back up when you get home from work. However, it is important to consider the health needs of your family, as some people with chronic medical conditions may need their climate more rigorously controlled than others.

Conserve Water
Using water in your home will also use energy. However, there are several ways that you can reduce your water use in order to lessen energy consumption. Consider simple solutions, like turning off the water in your bathroom sink until you are ready to rinse when brushing your teeth. Choose a shower over a bath in order to conserve water, and wait until your dishwasher is full before you run a load; this tip on its own could reduce your water use by nearly 1,000 gallons each month.
Also consider using cold water as often as possible. It takes a lot of energy to heat up the water used for showering, to do laundry, or to wash your dishes, so by keeping the water cold, you’ll save energy. These tips can be followed by family members both young and old, and they can make a big difference on your monthly energy bills.

Turn Off Electronics and Lights
Turning off lights and electronics when you leave a room is an essential activity for saving money and energy. Switch off your computer, radio, and TV when the items are not in use, as they will burn up energy. If you have appliances or other items that you don’t use regularly, consider unplugging them to prevent wasted energy.
At the end of the day, turn off your computer in order to cut down the amount of energy that it is using. Many homeowners don’t go through the hassle of shutting down their laptop or desktop each night, but even a computer on standby will use energy. If you are going to be away from home for a few days, unplug extension cords and surge protectors in order to further reduce your home energy use. By taking the time to complete these extra steps, you’ll be rewarded with lower energy bills.
