Off-Grid Wind Power

September 29, 2009

windturbineWind power is a great source of energy in some areas of the country. If you live near the coast or in the desert you will have a steady stream of wind on a regular basis. In other areas of the country the wind may not be as consistent so wind power may not be the best option.

Where I live it the winds pick up usually for two or three hours in the late afternoon, so wind energy would make a good back up source to solar energy as we get a high amount of sun in this part of the country.

There are many type of wind generators out there from extremely large to small. For a tiny house on wheels you might consider a marine type wind generator as these are small and can be rigged to fold up or down for travel. They have few moving parts so are very dependable and surprisingly affordable.

Rooftop generators are becoming a hot item and there are several versions being designed with the goal to make them affordable and available to the masses. I discovered this neat link to a website that shows several of these ideas in movie form. To learn more visit the The Rhode Island Alliance For Clean Energy and the page Residential Wind Power.

The following video proves that wind power can be built and manufactured using recycled materials and very inexpensively. How would you like to use everyday recycled products to manufacture residential wind turbines, which will give you your own energy independence!

As with any type of off-grid power you will need a way to store your energy and your power station will need the correct inverters and batteries to make your  home fully independent. Below is a picture of a power station with the batteries, inverter and connections all in one unit. This one is designed to have a nice size propane container built in also.

This unit is set up to accept the wind generators power, plus connect solar panels also. With the propane setup you could also install a propane generator for back up purposes.

Hopefully, this article will inspire you to research the wind energy potential out there and you will figure out the best solution for your current and future needs. Wind is a free source of power, you just need a good way to harness it and store it.

Living off the Grid

September 15, 2009

skystreamWhen we think of the term off the grid, we generally think of systems that provide electricity. However, many of these systems can do much more than that. For example, solar collectors can be used to heat water, which could be be transferred into heating your structure.

Wind power could be used to pump water. They also could be combined with other sources such as propane or wood to power a refrigerator or furnace.

You need to figure out which source of power is best for you or what combination will generate the most electricity for you.

Lets look at a basic set up and what you will need.

  1. A Generation Source: You will need either solar-electric panels or wind generators or maybe a combination of the two. Another idea could be water power. Your plan is to generate electricity.
  2. Energy Storage System: The most common way is deep cycle or golf cart batteries, which you connect to your system. The batteries store the energy you create for when there is no sun or wind to sustain your needs.
  3. Inverter: This is a devise that converts the 12, 24, or 36 volt DC coming from the batteries we discussed above so that they are usable with 110 or 120 AC needed with most standard appliances.
  4. Backup Generator: When natural conditions such as wind or sun fail you, you need a back up system to generate and charge your batteries. A generator of some type is needed for this. Some options include propane, diesel, or gas. These you would want to run during daylight hours so the noise does not bother your neighbors.
  5. Interface Connector: This devise is used so that you can be connected or disconnected with the grid. A lot of utilities will let you put the power you generate back onto the grid and thus reducing your grid costs.

It is recommended that you get work with professionals to get the best setup for your home. They can advise you on the best components and the correct amount you will need to meet your needs. So get to know your local alternate energy experts.

Often buying a complete system will save you money versus buying each part individually. Keep that in mind as you research your off grid needs.
