Vermont Home Harnesses Wind

In pristine northern Vermont, tucked in the woods, David and Mary Lahar have lived off the electricity grid since moving to their new home in Strafford in 1984. As David reports, concern for the environment and interest in alternative energy technologies were the underlying forces behind their home-building decision. The Lahars obtain between 75 and 80 percent of their electricity from wind, with the rest coming from solar panels.

They use wood for heating and use propane for instantaneous hot water, as a back-up heating source, and for cooking. The Lahars keep their electric needs modest, but recently David has considered putting up a larger wind turbine to provide for his family’s growing needs.

When choosing a lot for the 1,700-foot timber-constructed home, wind was a primary consideration. The Lahars conducted wind tests for a month before they made a final decision. An average of 8 mile per hour (mph) winds are enough to get the turbine paddles moving, and the site they finally chose for their wind turbine on Mount Mansfield has regular 10 mph winds. They constructed a 100-foot platform to raise the windmill above the tree line in an attempt to further capture the wind and installed a Sencenbaugh 1.2 kilowatt wind turbine with 13-foot blades.…

Alternative Energy Bangladesh: Reaching Where the Grid Can’t

[Via Alternative Energy Blog]

Bangladesh is experiencing a severe energy delivery crisis. The Financial Express of Bangladesh says load shedding and suspension of production in industrial zones due to low gas pressure is a daily occurrence. the Government is turning to solar energy to remedy the shortfall.

Access to electricity in Bangladesh is one of the lowest in the world. The coverage stands around 30 per cent of the total population. However, the rural areas of Bangladesh, where nearly 80 per cent of the population live, only have about 10% coverage.…

Power Toys

Here are a few technical toys for getting and using power in an off-grid home.

Power Toys
Power Toys need power

Starting with the NiMH battery Charger, it holds 4 AA or AAA NiMH batteries, and charges from 120vac housepower or 12vdc car power as input. About $20 from Walmart, and came with 4 AA NiMH batteries.

That gives me power for all those battery sucking devices like flashlights, remote control vehicles my boy’s like, clocks, and caller ID phones.

Next up in the Power toolbox is my Kill-A-Watt. …

What is off-grid?

Being off-grid means something different to everyone. To me it simply means not being tethered to the services one normally expects of society.

Steve Spence and his Veggie Gen
Steve Spence and his Veggie Gen

No power grid, no water or sewer grid, and in some cases, no communications grid. Some are permanently off-grid (like ourselves), others only temporarily off-grid, in the form of RV’s, boats, vehicles, etc. When one is off-grid, one has to provide some of those services (the ones deemed necessary) for oneself.

As a new addition to the Off-Grid team, I will explain ways to obtain power, water, communications and other self provided services, and show some of the neat appropriate technologies available to you in this area. I will be presenting solutions like Rain Water Harvesting, Composting Toilets, Solar, BioThermal and Wind power, Cellular and Satellite voice/data communications, and environmental controls (Heating/Cooling) in stationary and mobile environments.

I currently use a combination of wind, pv, and Waste Vegetable Oil (WVO) fueled diesel co-generation on our off-grid farmstead.

Welcome to the journey.…

Energy Alternatives

For a clear headed guide to alternative energy sources in a cold (UK) climate, visit Off the Grid.

Written by David Allender, who bought a remote house ten years ago and has steadily tested his way though each kind of alternative power, it tells you exactly which batteries to get for maximum reliability (Tungstone (now part of the Hawker group) – type YCP25) , or which is the best model of wind turbine. David is currently testing solar panels.…

More progress for UK solar industry

A new factory in North Wales could give the solar energy market in the UK the impetus it needs. The Sharp Corporation, the worlds major producer of photovoltaic (PV) products, initially expected that the new Wrexham plant would turn out PV panels for residential and commercial installations at a rate of 20 MW worth per year. But orders quickly exceeded output and the company announced that it would be doubling it’s capacity.…

Looking to nature creates a second chance for Welsh Farmers

Faced with a dramatic 75% decline in farming through disasters as diverse as Chernobyl and BSE, many Welsh hill farmers decided to pack up and try a new line in work. Not the three families that make up the Cwmni Gwynt Teg (‘fair wind’ in Welsh) cooperative. When faced with disaster in 1997, this ingenious group looked to the the mountains for inspiration and harnessed the wind, on their own land. They now run the Moel Moelogan Wind farm, a profitable and growing business.…

Fund your Off-grid dreams with OPM (other people’s money)

Wouldn’t it be lovely if someone offered you between 400 to 5000 to cut your bills, help the environment and get off-grid?

Following the success of the Clear Skies scheme, aimed to provide householders and communities with grants and advice to help reduce the amount of fossil fuels used and realize the benefits of renewable energy, the Department of Trade and Industry(DTI) has announced additional funding of  2.5m, and extended the scheme until March 2006.…

How to build your own Power Plant

So you live in a two bed room semi detached house in a regular housing estate. Despite appearances, (and perhaps assumptions), even the most conventional house can have it’s own off-grid revolution, and even go one step further; by becoming a power station in its own right.

And how would you do that? Through the implementation of a system known as ‘micro-generation’, which is quietly transforming energy in the domestic environment.…

Big ideas on the move

Gaining access to off-grid and green energy ideas couldn’t get any easier; the Green Energy Machine (GEM), from the National Energy Foundation will come to you. Designed to raise awareness through schools, fairs and exhibitions, it carries information and demonstrations on key renewable energy concepts. As well as carrying on board a wind turbine, wood burning stove, solar devices including solar bike and fountain, you can get free impartial advice on renewable energy sources. If you think you have an event, know a school that could benefit from a visit or just want to see it action call +44 (0)1908 665555 or visit www.nef.org.uk
