Staff Writer ablanks@minotdailynews.com The 21st century is the age of efficiency, especially when it concerns daily energy consumption. As the world becomes more environmentally conscious, and seeks less dependency on fossil fuels, geothermal energy is gradually gaining consideration among businesses, homeowners and the scientific community. “Numerous homeowners and businesses have invested in geothermal energy,” said Minot Community Relations and Communications Manager Tom Rafferty of Verendrye Electric Cooperative. “We have geothermal energy at both of our offices in Minot and Velva.” Founded in 1939, Verendrye has provided 77 years of service, while contributing 20 years toward advising members about geothermal energy. True to its tradition, Verendrye continues to address the needs of the community and encourages members to invest in geothermal energy. “We want to encourage our members to conserve energy,” Rafferty said. “It’s the smart thing to do economically and environmentally. So, we practice what we preach, and use geothermal energy to show that we, too, are practicing energy conservation.” Will Gosnold, of the Harold Hamm School of Geology and Geo- For residents of Ward County to learn about tax exemptions: logical Engineering at the Univerwww.co.ward.nd.us/264/Taxsity of North Dakota, echoes the Equalization ideas of Rafferty. “Environmentally, geothermal Database with state incentives for energy is very good because it prorenewable energy: duces virtually no pollutants,” Goswww.dsireusa.org nold said. Geothermal energy is heat extracted from the earth, that is nearly free of pollutants, completely renewable and sustains a yearly temperature close to 57 degrees Fahrenheit. To gain access to this resource, ground source heat pumps are built inside homes or places of business, in which they connect to a heat exchange system underground. For the exchange of heat to occur, a fluid (usually being water) is run from the ground source heat pumps, and through the heat exchange system which picks up heat from the ground and delivers it to a residence or place of business. During the summertime, the heat below the earth’s surface is cooler and throughout the winter months, the temperature beneath the ground is warmer than that above. As a result, geothermal energy can provide both heating and cooling options for its users. Throughout Minot and across the world, geothermal energy is being explored and utilized. “This ground source heating and cooling system is widely used throughout Europe,” Gosnold said. “This system could be much more heavily used in the states. You can use this for single houses, groups of houses, and buildings.” Not only can geothermal energy produce heating and cooling, it can also generate electricity.

“Out in the Bakken, there is a great need to pump the oil,” Gosnold said. “The source of power is electrical and gas fired power plants along the Missouri river. If you boil the water and run it through a turbine which then powers the generator, that in turns creates electricity. What they’re doing in that region where there is no car lines or real accidents, they are burning diesel fuel and propane on site. Instead, they could actually take the steam out the oil and water mix coming up and use that to generate electricity.” Energy conservation has benefited both Minot Air Force Base and parts of Minot State University, which currently utilize geothermal energy. John Webster, a professor of geoscience at MSU, has seen the campus convert to geothermal energy. Several buildings, including the MSU Dome, library, science building, and others are connected to a geothermal system. Aside from the initial conversion, MSU has yet to experience any glitches as the buildings are operating normally.

“Certainly there were some disruptions when the buildings were being converted,” Webster said. “As we did before, we have cooling and heating.” Michael Zerr, the owner and manager at Cool Fish Refrigerating, Heating and Air, cited increased geothermal usage among farmers. “On the farms, where you have families keeping the land for generations, we’re seeing more geothermal investments,” Zerr said. “Farmers are seeing long-term return on their investments. Despite the hefty investment up front, farmers know this could be useful for generations to come. Another thing to consider in the incentives available for individuals who are able to apply for them.” Whether you’re a farmer, business owner, or homeowner, there are a variety of websites that can financially assist your ability to purchase geothermal energy.

Solar energy is a flexible energy technology

S

olar energy is becoming an affordable, convenient source of power for businesses and residents alike in Minot. Solar power, energy that’s created from the sun that’s converted into thermal or electrical power, is the cleanest and most abundant renewable energy source available. The United States has some of the richest solar resources in the world. Modern technology can harness this energy for a variety of uses, including generating electricity, providing light, and heating water for domestic, commercial, or industrial use. There are several ways to harness solar energy: solar

One example of this is at Northern Plains Feeders and its use of five or six solar panels for watering cattle. Danny Seright, rancher and feed operator at Northern Plains Feeders in Towner, has had very little trouble with the solar panels. “Lightning might burn out a well but that could happen with anything using electricity,” said Seright. Solar panels and water pumping have become a natural fit. Generally, water is needed most when the sun shines the brightest. Solar modules generate the most

power in full sun conditions when larger quantities of water are needed to combat the heat. Because of this, solar is an economical choice over windmills and engine-driven generators for most locations where there isn’t utility power. Generally, the electric company doesn’t want to dig in remote areas for power cords due to cost restrictions. While solar energy is environmentally friendly, the main draw for the use of solar panels is cost and mobility. Seright doesn’t pay for power, just a flat fee for the equipment. Solar power plants can be located on site similar to Seright Ranch or as a central-station similar to traditional power plants.

While some utility-scale solar plants can store the energy they produce for use after the sun sets, one major issue is dealing with cloudy days. Seright is a member-owner of Verendrye Electric Cooperative, the non-profit cooperative that provides him with the solar equipment. He gets to vote for local citizens to serve on the co-op board of directors and the non-profit returns money to its members in the form of capital credits. With more than 200 solar panels in use, according to Community Relations Manager Tom Rafferty at Verendrye Electric Cooperative, North Dakotans are moving into the future of energy use.
