Everywhere you look these days you see someone going “green”. Car makers are developing solar powered cars, people are practicing water conservation and recycling services are common place in many states. Everyone seems eager to do their part. But it is true that some cities are moving faster than others and there are areas where recycling is still not offered and people everywhere who haven’t even thought about it. But the cities and peoples who have gone above and beyond in “going green” deserve some recognition.

In my search online to discover which cities rate highest, I saw that everyone from Treehugger to MSN, from Mother Nature Network to Move have done a rating of their own, based on available data. What I did was obtain data from the U.S. Census Bureau, the Green Building Council and the National Geographic Society’s “Green Guide” to compile my own. These findings are varied in some ways but overall pretty consistant. You will see each of these cities somewhere on everyone’s list. My list is based on everyone’s research of each cities’ resource conservation, waste emissions, public transportation use, recycling habits, number of eco friendly buildings and overall green space offered to determine which one goes where on the scale of 1 to 10. However, you could not go wrong by moving to any one of these lovely places, as they are definitely way ahead of the rest of us.

Perhaps you have heard about these and how they are a part of the solution to global warming. And perhaps you have also heard that Desert Hills Dairy Biodigester has begun plans and acquired land to construct the very first biodigester in the State of Nevada at Desert Hills Dairy in Wabuska, near Yerington, Nevada. But what the heck is it? And how can it help?

Biodigesters capture methane from dairy cattle to generate clean electrical energy! I know this sounds amazing but the problem created by cattle poop on meat and dairy farms is outrageous and dangerous and must be mitigated. You are aware, I am sure, that cattle poop is sold as manure for gardening and makes a wonderful fertilizer. Now, take the step mentally, from the energy and heat created by fertilizer to the energy required to make electricity. It’s really that simple.

The methane captured by the biodigester is enough to create a highly nutritious and non toxic liquid fertilizer, a high quality mulch by product that generates enough power to run both the digester and the dairy. This mitigates an enormous amount of the methane generated on the dairy and takes that much CO2 out of the atmosphere. Now, if we can just get them running on every farm and cattle ranch in the country.

According to the CEO of DHDB, Dr. Micheal Ganz, “Desert Hills is the largest and best managed dairy in Northern Nevada. We will use proven digester technology developed by GHD, Inc. in Wisconsin to obtain maximum yields from this installation.” Quote obtained online from Reuters.

Studies have proven that the methan produced from dairy cattle, in particular, has a greenhouse warming effect 21 times carbon dioxide. It has been established that a herd of 10,000 cows can produce as much as a billion cubic feet of methane annually. This information comes from studies performed at the University of Texas and from statistics compiled by the Midwest Rural Energy Council.

“At a time when the Nevada dairy industry has been severely damaged by the recession, income from a biodigester can make the difference between economic profitability and failure,” Dr. Ganz added, according to Reuters.

This is all well and good and I am very pleased with the ingenuity and effort that went into this device. American business will find a way as long as there is money and good will in it. However, if the climate bill gets passed as it is right now, this won’t make much difference. They’ll end up using the offsets from the diary farms to mitigate carbon creation at other locations, including China and India. As good as the biodigester is and I give kudos to those folk that invented it and are trying to use it, it will have nada impact on this mess if we don’t make everybody use it and not allow trade offs. Keep the pressure on. Write your congressman or woman and let them know how you feel.

Note: DHDB (Desert Hills Dairy Biodigester) is a subsidiary of Carbon Bank Ireland, LLC.
