25 Alternative Energy Strategies - 5

In this, the last five items in the list of 25 strategies, a look at community efforts to become self-sufficient is in order. While an energy self-sufficient homestead can exist in any rural environment, the more neighbors (no matter how spread out) who catch the bug, the more resources are available to be developed for the good of all. It’s the natural ‘next step’ in extending the idea of energy self-sufficiency toward the broader society.

The real “trick” in items 21-25 are the collective will to work together and agree upon sustainable agricultural, building, energy production and distribution practices.

Part 5: Collective Strategies for Communities

When FDR was elected President in 1932 - in the midst of the Great Depression - he addressed the awful situation by means of the “New Deal.” Tucked away in the National Industrial Recovery Act of 1933 which established the huge public works programs, was the Subsistence Homestead Communities project. The plan was to relocate some of the idled workers from over-populated industrial areas into planned subsistence communities they would build for themselves with government money.

Read about the Cumberland Homesteads project for yourself, it gives a rough idea of the rewards community development can reap, even if the whole thing is privately financed by the motivated homesteaders themselves (as it must be today). Sure, there are many grants available for rural community development (such as state agri-tourism initiatives) when there is someone skilled in applying, from all sorts of government agencies federal and state. And some resources available from corporate largesse these days as well.

25 Alternative Energy Strategies - 4

For homestead and/or community independence

We’ve looked a bit at on-site electrical generation, transportation fuels and building technologies. In this installment we’ll look at some ways of putting things together into overall strategies for homestead independence.


Part 4: Hybrid Energy Systems

In a previous post a short video was offered about as small, 1Kw hybrid energy system using solar and wind offered by a company in Canada. Whether you’re planning to go off-grid with storage batteries or negotiate a price for your excess production with the local utility (and get a “backwards meter”), the same thing is true of energy supplies as is true of general homestead success - diversify. So Here are five hybrid systems, some good links and some cool ideas for planning your alternatives…

25 Alternative Energy Strategies - 3

For homestead and/or community independence

A Happy Solar Homestead

When we discuss alternative energy strategies, any able homesteader is going to be concerned with building and various secondary retrofits to homes, barns and outbuildings. The more energy the homestead can gain passively - or conserve passively - the less energy will be required to supplement.

In these strategies 11-15 of the series, we’ll look at some of the ways a homesteader can use smart, green building practices and technologies to lessen their dependence on supplied energy sources.

Part 3: Building Technologies & Alternatives

11. Passive Solar Siting and Construction

Whether you’re building a new house or barn, or simply retrofitting to what’s already there, strategies for making the most of nature where you live will help to save on energy inputs.

To make the most of passive solar, consider how much direct sunlight falls on your homesite throughout the year. If you get ample sun (have a site that has an ample southerly exposure), plan accordingly. Big windows (with no significant overhang) can provide direct solar heating in the winter. Dark stain or paint on the south wall will also absorb heat from the sun. Conversely, walls that are mostly or entirely shaded during the day, plus the north wall, should have as few windows as is reasonable.

Limit heat gain in summer by planting deciduous trees (apples are good) fairly close. Also bear in mind that any south-facing roof is a good place to put solar panels or solar collectors for hot water (or both). If you do install these, you’ll want retractible awnings for your south windows because you don’t want any summer shade trees interfering.

25 Alternative Energy Strategies - 2

For homestead and/or community independence

In the first installment of this series we looked at 5 technologies for generating electricity - solar panels, other solar (thermal for heat differential mechanical energy or steam generation), micro-hydro power and wind. This post is about alternatives for basic transportation, motorized equipment around the homestead and in rural cooperative communities.

As the series is about all the alternatives, these transportation-related alternatives are numbered 6-10 out of the 25.

Part 2: Transportation & Motorized Equipment

In 1893 Rudolph Diesel published “The Theory and Construction of a Rational Heat Engine” and was eventually granted an American patent on his invention. His first models operated at about 26% efficiency, which more than doubled the efficiency of steam engines. By 1897 he’d achieved an engine that ran at 75% efficiency. Diesel demonstrated his engine at the Exhibition faire in France in 1898, and the fuel that powered it was peanut oil. It was Diesel’s vision that the engine could be used by small business owners and farmers and run on vegetable oil rather than then-expensive petroleum.

Then petroleum became so cheap that the entire transportation and farming equipment industries went with that fossil fuel instead. Now petroleum is once again becoming very expensive, and the air pollution problem from the burning of fossil fuels has become increasingly dire.

Most transportation - and some electrical generation - still uses the diesel engine. That’s some cars and light trucks, most all heavy trucks, city buses, heavy farm equipment (tractors, combines), railroad engines and ocean shipping. The gasoline engine, which uses a more refined petroleum based fuel, accounts for most of the private cars and trucks. What are the best present and upcoming alternative fuels?

25 Alternative Energy Strategies

For homestead and/or community independence

This series will provide an overview of the most promising energy systems and strategies for homestead or rural community independence. Most of these are available right now, some can be put together by the handy homeowner or community action group, and some will be available in the near future. Combined with common-sense conservation practices these can contribute a great deal to the independence of individual homesteads and rural communities willing to work together.

These technologies and ideas will be divided into particular technologies and presented together - 1. Electrical production; 2. Transportation alternatives - vehicles, fuels and power to operate the kind of equipment necessary to a rural lifestyle (trucks, farm and garden equipment, remote generators, etc.); 3. Building technologies and direct alternatives for heating/cooling and their applications; 4. Hybrid systems that can even out production and tie together for constancy of supply; 5. Collective strategies for small, cooperative communities striving for self-sufficiency and willing to invest together for alternatives that benefit all.

Part 1: Electrical Generation

We use electricity to light our homes and outbuildings, refrigerate our food, wash and dry our clothes, prepare our food, provide our in-home entertainment (music, television, computers), and sometimes to heat or supplement our heat during the winter. The “average” electricity use per home in the US (this is something we can personally adjust downward by conservation and appliance/heat alternatives) is ~900 Kilowatt hours per month. Get that down to ~700 for your home/homestead, and we’re talking less than 8,500 KwH per year.

What are the best alternative sources for that much on-site electrical generation?

Working Hybrid Wind-Solar System

Here’s a short video demonstration of a hybrid home electrical generation system developed by SEMA Technology that we’ll be exploring in more depth later. While it does depend on a storage system (battery), it would only take one of these to power my homestead. I’d still have to weigh longevity of its capacity and cost of replacement before I’d change my mind about going with the backwards meter. Which might cost me less over time and avoids the necessity to either turn off the solar cells or send the wind energy to a heat sink as waste.

Next week I’m planning a series looking at the best and most affordable technologies out there right now, and what’s on line for the future.

The Excitement of Discovering an Endangered Species

…right there in the yard for all to see!

I visited the daughter of a dear friend of mine last summer. It was her 12th birthday party, which I wouldn’t have missed for the world - I’ve known and loved this young lady since before she was born. The party was held on a stretch of flat lawn below the house, which is a ~70-year old timber frame atop a tall knob in Asheville, North Carolina.

There’s a path with timber-crossed bark-backfilled steps winding down the hillside from the house to the lawn. At one point along the path there’s a little grove of tall hemlocks, blue spruce and Frasier firs with a rhododendron mid-story boundary that’s cool even in the heat of summer. An old rope swing that doesn’t look strong enough to hold anyone anymore dangles from a lone oak’s limb, a little shady clearing off the main path. There, blending unobtrusively amongst the firs and hemlocks was a different kind of tree - different enough to catch my attention sharply that day. So I collected a needled twig hoping to identify it when I got home.
