    Geothermal heat is keeping Habitat for Humanity’s new home in North Pole toasty at half the cost of a regular water boiler, delivering savings directly to the family who moved into the house in January.

    Now, the non-profit has another geothermal project on the table. With high heating fuel prices in the Interior, and a federal tax rebate in place until 2016, is geothermal a viable heating source for Interior Alaska on a large scale?

    A house delivering savings

    Habitat for Humanity is a nonprofit organization that constructs homes for families in need. The family then buys the house from the organization, paying it back on a 20-year loan with no interest.

    Part of the organization’s building standards are that the costs to live there cannot exceed 30 percent of a family’s gross income. “The heating part of it is huge,” executive director Jay Pruce said. “That’s what puts (families) in sub-standard housing.”

    Geothermal heat pumps, also known as ground-source heat pumps, work by extracting heat from the ground through a closed-loop system of pipes called a heat-exchange system. The systems can be installed either horizontally or vertically in the ground, and rely on electricity to run. For a house to be outfitted with geothermal, it needs to have either forced air or radiant heat systems.

    Ground-source heat pumps used to heat homes are different from geothermal power derived from underground hot springs such as that used at the Chena Hot Springs reso...

    People don’t like being forced to purchase things they may not want, which is why over half of us are hoping that the Supreme Court throws out the individual insurance mandate in President Barack Obama’s health care plan.There’s also a worldwide rebellion brewing against being forced to purchase expensive electricity produced by so-called “renewable” sources, now being exacerbated by the availability of very cheap natural gas from shale formations.But, here in the U.S. there are some 30 different statewide “renewable portfolio standards” (RPSs) that also mandate pricey power, usually under the guise of fighting dreaded global warming.RPSs command that a certain percentage of electricity has to come from wind, solar, geothermal, or biomass. Given that this power generally costs a lot more than what comes from a modern coal or gas plant, your local utility passes the cost on in the form of higher bills, which the various state utility commissions are only too happy to approve in the name of saving the planet.

    RPSs generally do not include hydroelectric power, which produces no carbon dioxide. It’s also much more predictable than solar or wind, and costs about the same as the average for gas and coal combined. It’s not in the portfolio standards because dams are soooo 20th century, and it isn’t a darling of the green lobby, like solar, wind and bio...
