If NYC Can Do Geothermal, Anybody Can Do Geothermal

LET'S FACE IT, WE ARE CREATURES OF HABIT, and when we get used to paying a certain amount for utilities, and become accustomed to replacing our air-conditioners every 10 or 15 years, why mess with the status quo? Want proof? Consider the metric system. It seems that in the US, it takes a couple of generations of adaptation, and then significant arm twisting to pull us out of our habitual comfort zones.

Geothermal Infrastructure; Pay Your Heating Bill to the Water Company?

THE DAY IS COMING IN WHICH CITIES will no longer allow combustion heating (NYC 80X50; #ONENYC).  Cities and governments throughout the world have already, and continue to make similar commitments. There is only one power alternative to combustion heating; electric power.  Consider the increasingly renewables-powered electrical grid and we find that there are only two non-combustion choices available; electrical resistance heating and heat pump technology.

Geothermal Heating and Cooling Book; Real Cheap, Really Good!

IN MY EFFORTS TO GET UNDERSTANDABLE and easy to read information into the hands of consumers about green technologies, it is refreshing to see an affordable book come out on geothermal heating and cooling technologies. The new book, “Geo Power” is just that; affordable, understandable, and richly illustrated.

Renwable Energy; YES!   Metric Marvels; Not so much...

OLD HABITS DIE-HARD. Many of us can remember when the public school system curriculum began metric instruction.  In 1970, I was a student at Skyline Elementary in Barstow, CA.  I distinctly remember Mrs. Sims sharing the Metric System with us in 1st grade, stating that by the time we were in high school, the Old-English measurements of miles, pounds, and pints would be all but history. What happened?

I also remember the promise of electric cars, on-line shopping (they called it “TV shopping”) and solar energy; all by the time we were in high school. I’m pleased to see that even though it’s taken a bit longer (45 years later), most of those energy efficiency initiatives have become a reality. I don’t know what to say about the metric system...

One of the forms of renewable energy that is enjoying widespread acceptance (unlike the “Metric Marvels”) is geothermal; so much so that we are have remarkable interest at elementary and upper-grade level studies.  I get increasing numbers of requests from kids all over the country for information that they can use in reports and essays on geothermal heat pump (GHP) technologies.  That’s great news.

Geothermal HVAC and the “Negatherm” Factor

In our first geothermal book, Geothermal HVAC, Green Heating and Cooling (McGraw-Hill Professional, 2010, p16), Brian Clark Howard and I shared a dialogue from an article wherein a commenter said that switching from a gas furnace to ground sourced heating is increasing the burning of fossil fuels, because the power plant producing the electrical power is probably burning coal, natural gas or other fossil fuels.  The argument seems valid until you understand what we call the “Negatherm Factor”.

 “Negatherm” is a term that was coined to refer to energy that would or could have been used from fossil fuel consumption, but was never used.  “Nega”, root of “negative”, meaning unused, and “Therm”  a unit of energy equal to 100,000 BTU’s, usually measures the combustion of fossil fuels for heating a home or business.  When heating from an appliance using electricity, we use “kilo-watt-hours” (kWh).  Electricity comes from many different fuel sources including hydroelectric, solar, wind, hot rock geothermal, nuclear, natural gas, coal, and diesel to name a few.  We are certainly seeing an increase in the renewable sources, the first four in particular.
