With the escalating price of natural gas and other fuels, geothermal heating and cooling has become an increasingly popular alternative for residential and commercial applications. Where conventional methods burn fossil fuels to create heat, the geothermal process simply harnesses the existing energy of the earth. A mixture of water and non-toxic antifreeze is constantly circulated through a closed loop of pipe buried in the ground in vertical or horizontal bore holes. In winter, the earth’s heat is absorbed by the circulating liquid. Ground source heat pumps transfer this heat to the building; in summer, the process is reversed, thereby dissipating the heat from inside the building into the ground.
Bertram Drilling Corp., and it’s sister company, Bertram Drilling Inc., of Billings, Montana, have been involved in the drilling of bore holes and installation of closed loops and geothermal equipment for many years.

Martin Energetics is the dba of a consultancy that first operated as a residential design and solar thermal sales and installation effort in the early 1980s that included contract training for residential energy auditors and Title-24 workshops for California SMACNA. Its Principal was a full-time college instructor at the time and his remote location in the northern Sierra Nevada did not support this side business.
When Bill’s retirement from 35 years of teaching came in 2006 and plans for his “last house” were being finalized with geothermal in mind, the Martin Energetics moniker was revived. Within a three year period, a frenzy of activity ensued. Bill designed and built that house as the general contractor and electrician, and designed the geothermal system it carries today. He also was project coordinator on a 7-ton, two heat pump system in the same community. He went to Stillwater, Oklahoma for his installer certification, joined CaliforniaGeo, and became emphatic about carbonless Zero Net Energy.
His all-electric home completed its first year as a solar NEM customer of PG&E in November, 2015 and demonstrated Zero Net Energy positive performance by exporting 1,500 Kwh more to the utility than was used. Bill serves as CaliforniaGeo’s President.
