Dart-AM Farms, LLC is currently using the direct heat from this geothermal source to heat two greenhouses and soil in the field. In 2011, they also plan to install a water-pumping windmill and to develop a combined heat and power system. The company has invested in solar, wind, and geothermal power to continue with these projects.
Projects under consideration
Unalaska – The Makushin geothermal resource near the community of Dutch Harbor on Unalaska (Aleutians) is the only proven high temperature geothermal system in Alaska that could be used for power generation. An exploratory drilling program, which took place in the early 1980s and was funded by the Department of Energy, made this determination. The City of Unalaska is planning further drilling in the area in the summer of 2009.
Akutan – The City of Akutan on the Aleutian Chain in 2010 was in the process of drilling two exploration wells in Hot Springs Valley to investigate providing power and heat to the city and a local fish processor.The first well produced water in excess of 360 degrees Fahrenheit. Though early, that result is encouraging for development of a large-scale geothermal power system.
Mt. Spurr – The Mt. Spurr volcano, across Cook Inlet from Anchorage, is a yet unproven resource, but its proximity to Anchorage makes it worth further assessment. Ormat, a geothermal developer and power plant manufacturer, purchased all but one lease section of the volcano for $3.5 million in a competitive bid process. In 2010, Ormat conducted several pre-drilling surveys such as aeromagnetic testing and ground-based geophysical surveys, as well as drilling two temperature gradient core holes, which yielded encouraging results. As of summer 2011, Ormat is drilling additional, deeper core holes in attempt to collect additional geological data about the actual geothermal source. They have projected a six-year best case scenario time line. If all goes well, Ormat hopes to build a plant by 2016.
There are no utility-scale solar power plants in Alaska. Most solar photovoltaic development is in remote areas with stand-alone grids where the cost of alternative electrical generation is extremely high. Utility-scale solar power plants are uneconomical in Alaska with today’s technology, but numerous small residential and commercial systems exist throughout the state.
Nome – Bering Straits Native Corporation installed a 16.8 kW solar PV array on their office building in March, 2008. The PV array produces about 16,000 kWh of electricity per year, offsetting about 1,000 gallons of diesel fuel. BSNC has also installed solar hot water heaters on two corporation-owned apartment buildings.

Alaska has significant potential to develop all forms of renewable energy.
With high energy prices afflicting many rural areas, Alaska also has the incentive to become a leader in the development of renewable energy resources and expertise. According to the Electric Power Research Institute, the state has over 50 percent of the nation’s wave energy resources and over 90 percent of the counry’s river current and tidal energy resources.
Additionally, Alaska has some of the best wind resources in the United States, a large number of volcanoes and hot springs, numerous opportunities for the production of fuel and heat energy from biomass, and receives more sunlight during the summer than the equator.
Because many types of renewable energy resources are developed and utilized locally, Alaska’s lack of energy infrastructure makes renewable energy an ideal means by which communities can generate stably-priced, environmentally responsible energy.
There are seven major forms of renewable energy resources, all of which are abundant in Alaska:
These sources include biomass, hydropower, geothermal, wind, ocean and solar energies. Nuclear energy is not considered a renewable energy because it is produced from uranium, a finite resource. Common uses of renewable energy include electricity generation, transportation fuels, and direct heating.
