Documentary — Nebraska Retiree Uses Earth’s Heat to Grow Oranges in Snow

Analysis by Dr. Joseph Mercola Fact Checked

September 14, 2019


STORY AT-A-GLANCE

Tropical fruits can be grown in subzero climates with geothermal energy

The only heat source for geothermal greenhouses is the Earth’s heat, which is 52 degrees at 8 feet deep

Energy costs to run a geothermal greenhouse are less than a dollar a day

Harmful herbicides and pesticides can be avoided with geothermal greenhouses

Geothermal greenhouse produce is marketable at local farmer's markets

The crops can be more profitable because there are few transportation costs involved

Finch's geothermal energy-based farming has been fruitful, pun intended  ;D. The greenhouse includes 20 citrus trees with 13 varieties of fruits, along with cacti, orchids, nine varieties of grapes, figs, avocados, ivy, tomatoes, garden plants and flowers.6 One 24-year-old tree will grow to be 100 years old or more, says Finch.7

Each tree is capable of producing as much as 125 pounds of fruit every year which Finch sells at local farmers markets.8 The year-round growing and low transportation costs help the marketability of the products says Finch –– and "locally grown" can be just as much of a sales point as "organic." Finch sells Valencia oranges, the fruit from which most juice comes. The temperatures are so salutatory, you could probably grow bananas too, he muses.9

Yet the energy costs associated with running the geothermal greenhouse are surprisingly low –– less than a dollar a day. A geothermal greenhouse Finch designed for a local high school in Alliance has used an average of 96 cents a day in energy costs for the last several years.10
