DIY Alternative Energy

Are you handy or even willing to try to be then how about visiting Instructables Alternative Energy DIY? Following our renowned and highly technical search of the internet we found this great site. Yup, that’s right we just stumbled on it while researching something totally different. So we just had to join and tell you about it.

Though in all fairness we should warn you that we haven’t tried any of their posted DIY (do it yourself) yet so please be wary. They list great projects such as Solar Thermal Water Heater For Less Than Five Dollars, 1000 watt wind turbine , Solar Heater, Make Your Own Biodiesel!, Solar Power System,Building a micro solar generator, and many more. Plus they have a category devoted to going green. The site has been online since June 2005 according to alexa and linked to from over 1700 other sites. So some of you may know about the site, for those who didn’t give it a look.

We will have to try some of these projects and let you know what we think. If they work we will certainly let you know. If you try one first let us know how it went. It’s science fair time for our children so we are already tied up on the new project front for a little while. Of course we encouraged them, though it wasn’t hard, to do something with renewable energy. Nice to see it is now an accepted project now. A few years ago when our son was doing his first it wasn’t on the list. The younger they are exposed to the possibility that having wires run to your home is not necessary the better.

I do have to say that when problem arise, like they always do, our children have been very encouraging to complete our goal of getting completely off the grid. Still being in a suburban (almost urban) environment has added challenges and the economy right now really isn’t helping but we are determined. Making the small changes we have and now moving to more major ones has been an adventure. One that has already produced results. We have lowered our utilities bill to the local gas and electric company by about $200 a month just in the past year. That means in last three years we have cut in half our winter bill form over $800 to between $250 to $375. It seems amazing that just changing how we used energy, adding additional insulation, changing to energy star appliances and light bulbs could make such a significant change. Take into account that we had a significant increase in our energy costs in Maryland in the last two years and its even more amazing. So our hope is that by the end of this summer we will have panels installed to supplement if …

Making Energy From Thin Air

Using wind turbines to generate your energy needs is like making energy appear from thin, moving, air. Especially if you are building a new home in a remote location. Wind energy systems may involve a significant initial investment but once you account for the lifetime of reduced or no utility costs it’s a steal. Though the time it takes for you to start making free energy, when your system has paid for itself through your savings that resulted, will be dependent on your system choice, wind resource at your location, electric rates, and how you have your system setup.

Small wind systems can work both on and off the grid depending on your needs, resources, and your desire. An on grid wind turbine system can help reduce your use of public utility-supplied electricity. This way your public electric utility can supply any energy need your turbine cannot supply. On the flip side when your wind turbine produces more energy then your need it can be sold to your utility (depending on state/local regulations). With the interconnections available today the switch can happen automatically. Conditions for a grid connected system are:

  • Living in an area with average annual wind speeds of at least 4.5 meters per second (10 miles per hour).
  • Grid supplied electricity is expensive in your area (about 10 to 15 cents per kilowatt-hour).
  • Local/State requirements for connecting your system to the grid are not too expensive.
  • You can legally erect a wind turbine on your property, check local building codes.
  • The long-term investment is possible for you.

Stand alone wind systems are designed for homes, farms and/or communities that are located away from utility lines and located in practical conditions. Conditions to look for are:

  • Living in an area with average annual wind speeds of at least 4.0 meters per second (9 miles per hour)
  • Grid connections are not available or can only be done by expensive extension. Running a power line to a remote site from the utility grid can be prohibitive, it can range from $15,000 to more than $50,000 per mile, depending on your terrain.
  • A decided interest in gaining energy independence from the utility
  • A desire to reduce the environmental impact of electricity production
  • Understanding the intermittent nature of wind power and have a plan for using other resources to meet your power needs during down times.

graph_we_fig1-52320226% of the contiguous U.S. land area has the potential to supply more than 1 1/2 times the current demand for electricity in the United States. The estimated wind resource is categorized into power classes of 1 to 7. Each class represents a range of wind power density at at a specific height above the ground. Class 1 is unsuitable for current and future wind technology. Class 2 is only marginally acceptable. Class 3 may be usable, above marginal, with future technology. Class 4 and above are …

Let the Earth Keep You Comfy

What better way to go off-grid and be cozy then to let the Earth’s own geothermal work for you.

Geothermal, GeoExchange, earth-coupled, ground-source, or water-source heat pumps are all use the constant temperature of the earth as the exchange medium instead of the outside air temperature. By doing that this system has a much higher efficiency (300%-600%) on cold winter nights then air-sourced heat pumps (175%-250%) on cool days

Since many areas if the US experience seasonal temperature extremes, from scorching heat in summer to sub-zero in winter, a few feet below the ground the temperature remains relatively constant. This temperature ranges from 45°F to 75°F (7°C to 21°C) depending on the latitude. Think of a cave, it’s warmer then outside in the winter, while cooler in summer. These GHP systems take advantage of that when they exchange heat with the earth through their ground heat exchanger

Geothermal and water-source heat pumps are able to cool, heat, and supply the home with hot water (if equipped). Models available of geothermal systems can include a two-speed compressors and variable fans to increase comfort and energy efficiency. Another plus is that compared to air-source heat pumps they last longer, need less maintenance, are quieter, and outside air temperature has no effect

The dual-source heat pump uses both geothermal and air-source heat pumps. By combining both systems best aspects you get a higher efficiency then the air one alone, though not as efficient as the true geothermal unit. The lower cost of the dual-source system and ability to work almost as well is a strong plus for this system.

The cost of a geothermal system is several times that of the air-forced system with the same capacity. This additional cost is recouped in your energy savings over the first 5-10 years. Since the internal components have a life is estimate of 25 years, with the ground loop at 50+ years, you will be reaping those energy savings for a long time to come. There are four distinct types of geothermal systems, three of those are closed-looped and 0ne is open looped.

closed_loop_system_horiz-9308512

The horizontal closed-loop type of installation is generally most cost-effective for residential uses, especially in new construction where land is available. It requires trenches to be at least four feet deep. The most common layouts are either to use two pipes, one buried at six feet, and the other at four feet, or two pipes placed side-by-side at five feet in the ground in a two-foot wide trench. The Slinky™ method of looping pipe gives more pipe in a shorter trench, which cuts on the cost of installation and makes horizontal installation possible in areas where conventional horizontal applications would not fit.

closed_loop_system_vertical-1884832

For schools and large commercial buildings vertical systems ar e often used because the land area required for horizontal loops would be a problem. Vertical loops are also used where …

Green Can Make You Some Green

On the “The Early Show” a segments was noticed about green jobs and how they are growing both in need and in pay. Even in today’s economy this segment of the job force is growing and paying well. So learning all you can about taking your home off-grid and making it more green can actually lead you into a new career.

After installing your own solar panels you can look into becoming a solar panel technician. You can do that by attending a vocational program or entering a community college and getting an associate degree. Which has the median pay of $40,000 right out of school. Not to shabby and you are hlping our environment and energy crunch at the same time.

Or you have made your home a healthy one by selecting eco friendly products, ergonomic furnishings, and green products for cleaning. Have a knack for design or love to help others get green and you should look into becoming a healthy home decorator or advisor. Use all that research you did to make your home healthy and self-sufficient for you and your family and help others do it too. The sky can be the limit or it’s a great way to make some extra money on the side.

Have you started making your own soap, honey, clothes, lotions, ect. because you couldn’t find it made healthy enough for you? Started a business that uses green or alternative energy sources to make your business more environmentally friendly? Any of these ideas and more are now being looked at by the big corporations to help them get in on the green and eco-friendly markets. “Burt’s Bees”, the lip balm maker, was bought out by Clorox for $913 million, “The Body Shop”, that green store that was in most of malls, was acquired by L’Oreal for $1.4 billion, so who knows if something you started or are thinking of starting might not be next.

So next time your staying up late, researching what product is best for your home, installing something to make your home more efficient or an alternative power source you just might be finding a new career for yourself.…

Intro to solar power

You can get started with a basic system that will power your phone charger, computer and car stereo most of the year for around �550 (add 25% for dollar price). As you add more or bigger panels, and more batteries, the price rises accordingly. A typical small domestic set-up for solar panels might be 4 � 85W panels costing �1,544.80, plus the extras – batteries, inverter, cabling, surge protector.…

AVA Makes it’s Television Debut

By: Kelly Mead

We were pleasantly surprised that while watching “Invention Nation” tonight we we able to see the $1 solar panel production. The guys headed out to Colorado to see the new type of solar panels that should be mass produced by next year. AVA Solar is still planning on entering it’s large scale mass production by 2009.

Seeing the production of these panels showed how these panels will use less materials and energy to produce. Which will be passed on to us as consumers. These panels are produced by layering the components and then scoring to make the individual cells, instead of making a large cell then cutting and wiring together. This means less places for lose connections and lose connections means less energy efficiency. Also as these panels will be produced completely in an automated process less energy and materials will be lost or wasted in the production. Less waste is always better for our environment.

We just had to get the information out so that you can watch the production and find out more on AVA Solar panels. It will be re-aired in the morning of January 29th if anyone is lucky enough to catch it. The episode to catch is #10 “Self-Sustaining” you can check “Invention Nation” schedule here. We of course found more to write about in this episode such as EarthHaven and Enertia, but wish to do more research on those.…
