In other greenhouses in Iceland, they have also been able to produce bananas. Many of their greenhouse operations are still developing expertise as they have only recently started looking at the grow lights use in the production of marijuana which they hope will improve production. These lights would be powered by the clean energy coming from the geothermal electric plants.
In the United States Midwest where the winter is long and cold, there are geothermal greenhouses producing fresh fruit and vegetables. In Nebraska, there is a geothermal greenhouse operator who is growing oranges, figs, lemons, grapefruits, and grapes. The greenhouse cost $22,000 to build and cost a $1 a day to operate its electrical fan system. The operator Russ Finch suggests a number of advantages: the land he is using is cheaper than traditional growing areas, there are no shipping costs, the produce is fresher and no burning of fossil fuel to transport over long distances.
In Southern Alberta, Canada town councils are partnering with a company to create geothermal greenhouses that will provide the community with jobs, year-round fresh produce, and also an indoor community garden. The company initially will build 20 acres of greenhouses, over shallow geothermal zones that have temperatures of 40 to 50 degrees Celcius. The company hopes to build out over time 70 greenhouse facilities in Southern Alberta. All operation on the cheapest cleanest energy on the planet
Geothermal allowing us to grown fresh food in the coldest of winters, with no carbon footprint and it is a major break though in food production which boosts local economies with jobs and providing increased food security.
