Power #3: Our Solar/Wind/Generator Power Compared to City Power Costs

Power #3:  Besides solar and wind power, our other fuel sources are wood and propane (and a backup generator). 

How do our costs contrast to traditional utility rates in a similar climate?  For comparison, I looked at municipal utility/service costs for an average single family home in Anchorage.  It is not an apples-to-apples comparison, because those residences are surely bigger than our little cabin, and sport a flushing toilet (those lucky people) but by adding our outbuildings (the shower/wash house, outhouse, pantry shed and tool/power shed), many of which have electricity and one of which has water service, it may be an informative comparison.  

The results of the analysis: On all utilities/services that can be accomplished by human labor or portable devices, our costs are far lower than city rates.  However, on those utilities that require infrastructure, our costs far exceed those of city folk...for the first several years.  See below for details and conclusions. Do you find any ideas for your home?

Power #2: How Well Do Our Solar/Wind Power and Communications Work?

(I welcome your comments and questions through the "comments" option below any entry. --Laura)

Power #2: With the bases and tower built over the prior two seasons (see blog entry, “Building the Power Tower,”)  the second summer’s project focused on installing the power and communications components that we bought from Susitna Energy of Anchorage.  These items were hoisted, tested, repaired, and in some cases, replaced over the next few seasons by the skillful remote power team at H and K Energy of Anchorage who flew out with every conceivable tool they might possibly need for each project they anticipated, as well as for troubleshooting any surprises (since the only way back to their shop or Home Depot was by plane).  We all know how important it is to trust and maybe even like the repair people who work in your home.  It is even more important when, in a remote situation, they sleep on your living room floor and eat with the family!  H and K Energy has stayed with us for several days each, once or twice a year, remaining until like magic, I could call my mother and turn on a lamp.  Over the years, I have come to look forward to their companionability as well as yet another high-tech enhancement.  

(Note:  the following article is much more technical than any other on the site.)

How Do We Get Stuff with No Roads?

(I welcome your comments and questions through the "comments" option below any entry. --Laura)
 
Brrrr!
Because our home site is remote, everything we use has to be:
(a) local, like wood for building or fuel, or water, from the lake or
(b) expensively transported from elsewhere.  Transport is determined by weather, weight, and dimensions.  This means that shopping lists are developed for needs anticipated a year in advance, and have to include a hefty supply of redundant parts and equipment and dry goods. 

During the winter, the rivers (the –na suffix in names like Yentna, Chena, Susitna means "river: in the Athabaskan language) become “highways” for remote areas, allowing snow machine trailer transport of large, heavy and flammable items, like mattresses, or 55 gallon drums of diesel fuel that are not allowed or are prohibitively expensive to transport by ski or float plane (usually Cessna 182s, 206s, or de Havilland Beavers and Otters).  As of 2011, the planes from Anchorage charge $0.50 per pound unless you charter the whole plane.  Since a whole plane charter costs from $300 – 600, there is an obvious incentive to fill it with over 150 pounds of goods, since a 50 lb bag of groceries will cost $25 to transport by itself.   Each air taxi service has a shed or two at Lake Hood (the largest float plane airport in the world) for accumulated piles of purchases by bush cabin owners like us until time to fly them out.   
The alternative mode of transportation is by snow machine cross country and up river 42 miles, about 3 hours.  That is 42 miles to the boat launch.  Not to Walmart.  Before we bought our own snow machine, our neighbor charged us $300 per day for hauling everything he could carry on his trailer, which holds up to 1000 lbs. He snow machined up river, switched to his truck, stored near a river landing, and then made up to 13 shopping stops (for construction supplies, fuel, furniture, and anything else we could think of) before returning to the pier, loading up his snow machine trailer, securing his truck, and then traveling home, down river and cross country.  That $300 works out to about $0.33/lb for shopping and transportation.  It was well earned and easily paid!

Power #1: We Build an Off the Grid Power Platform

(I welcome your comments and questions through the "comments" option below any entry. --Laura)

(Power Article #1)  This is one of several articles on this blog describing the power platform my husband built off the "grid" with skillful Alaskan service providers.  This article describes the building process (without power tools).  The other articles describe the cost and functionality of the components we installed (and what worked and didn't), and how much power we use. 
----------------------------------------
Building it piece by piece
Want Power?

For many city/suburban people, the conundrum to overcome in installing wind or solar power is the upfront cost and pay back time vs current monthly utility bills.    On the other hand, in dilapidated towns in northern India, with, presumably, unreliable energy, every hotel we stayed in had solar powered water heaters dating back to the 1970s. For us, out in the bush, closer to Rajasthan than Rochester, we had fewer cost/benefit issues to debate.  Want power?  

Two choices: 

A: gasoline or diesel powered generator or B: some combination of wind and solar power.

 As a matter of fact, after we bought our remote property in South Central Alaska, the first building goal, before cabin, outhouse, or any other structure was power for communications. Since my husband is not retired, the determiner of how long we could stay out in the boonies was the quality of communication technology.  His goal was not heat but Internet, not water but a phone.  As the project evolved, it seemed like many a man’s dream:  he could pee behind a tree (well, a million of them) while checking his blackberry.  From a wife’s perspective, those are two of the worst scenarios combined, but I digress.

The Land is Prepared for Buildings But I'm Not Prepared for this endeavor


(I welcome your comments and questions through the "comments" option below any entry. --Laura)

Although my husband had the vision to anticipate what this property could become and what it would mean to him, I definitely didn’t.  Our first few seasons felt like the absolutely bleakest way to spend a summer, like some chain gang of convicts clearing swamps for future county roads to nowhere.  I was hot, sweaty, bored, humiliated, sore, and lonely, particularly when he would disappear for a week at a time on business.  I had absolutely no confidence that Bryan had any idea of what he’d gotten us into.  One day, when the weed whacker’s head spun off, sending in who knew what direction all the little screws and washers under ferns and devil’s club leaves, I sat down in the middle of the forest and cried.  “What are we doing here?  You don’t know anything!” 
We didn’t have any of the right tools and we invariably broke the old ones our neighbors loaned us, in what started to seem like a canny plan to get new replacements from hapless cheechakos, as neophytes are known.  We certainly were naïve.  Each replacement required expensive arrangements to fly them out by air-taxi, along with anything else we suddenly realized we’d need, although we as yet had no place to store them.  Weren’t husbands who bought land in Alaska supposed to intuit all this stuff?
