Wind power works best in areas with steady directional winds. You see the most use of wind turbines in flatter landscapes with few obstructions such as large open rangeland, coastlines, etc. These spaces are large enough to put multiple turbines and increase the chance of profitability.
A smaller space doesn’t mean some wind energy cannot be harnessed but for large scale wind power for residential use, large wind power operations and major infrastructure would be needed.
Cut in speed
Wind turbines do not start generating power until winds reach a certain threshold. A low cut in speed is about 5-8 mph. You need to make sure you read the cut in speed before you buy a turbine to make sure it is practical for your property.
Areas where winds happen often but are not steady means the turbine is not going to generate power effectively. Be suspicious of turbines that have to good to be true claims about cut in speeds.
Appearance of Turbines
There are things that can be done to make turbines more attractive but they still take up a lot of space on a landscape. If you are in a neighborhood there is no guarantee that your neighbors are going to appreciate your contribution to the view. In some communities there may be height restrictions and other rules about what you can put up. If you are member of a homeowners association you may want to double check rules before you invest in your wind system.
Coastlines with steady winds are a popular place for wind farms but some areas have fought against this form of power due to the effect on the appearance of the shoreline. Some places that rely on tourism heavily have decided not to allow wind turbines at all.
On calm days, you have no power unless you have a lot stored in batteries.
Battery banks are essential to getting the most our of wind power. You have to have the storage to harness the energy when it is there for the taking. If you draw off your batteries and then have no wind for a few days you could find yourself short on power if you don’t have adequate back up.
Wind turbines at remote locations require transmission lines.
Just like regular electricity, wind power has to sent to where it is needed. This means wind farms need to be close to where power is needed to prevent energy losses from becoming greater than desired.
For large scale residential power there would need to be some major wind farms. Since wide open spaces are not always close to where the power needs to go there would need to be transmission lines ran which would require regular upkeep and be susceptible to inclement weather.
What some do not realize is that when any type of power is transmitted through a line, there is some loss of power. The further the energy has to travel, the greater the loss. There are ways to reduce some energy loss but there is always going to be some.
Wind power has to compete with other land usage that may be more profitable.
Wind turbines located where real estate is hot may not be considered realistic. A good view can have a positive impact on property values. Some people consider the sight and noise of turbines unappealing so property values and tourism could be impacted.
Just because an area seems perfect for wind doesn’t mean it is cost effective. Most people that are invested in property are going to choose a use they can live with and make the most money at if the property is an investment. That means that if housing is in short supply for example, land is going to be used for a development rather than a wind farm.
Although the cost of setting up a turbine farm has decreased, it is still a high enough level of initial investment that it makes those with some of the resources approach it with much caution.
Turbines can result in bird death.
Birds are not smart about turbines. They simply don’t know what they are so by the time they realize they are in trouble it is too late. The larger the turbine the more of this you are going to see.
You can do some things to discourage birds from making it to your turbine like putting out feeders in a different area of your property but even doing this you can still expect to see some bird casualties.
Wind energy does mean buying and maintaining batteries.
The manufacture and disposal of batteries over time is the one major environmental impact of wind turbines besides the death of birds. Good batteries can be a substantial investment. Four batteries can easily cost $400 but if they are maintained well then they will last you for many years.
It can generate income for some land owners.
Wind farms can be combined with farming enterprises such as grazing cattle, sheep, or goats. Some may even grow grain crops below the turbines. Some landowners rent the space out to someone that puts up the investment capital to start the wind farm, thus avoiding any upfront cost and generating some rent.
If you have a good location for wind power it is possible that you could generate some income by selling energy back to the grid. Some power companies may have better rates than others so it is best to check it out to see how quick you can expect to see a return on your investment.
Of course if you own rangeland that is grazed and has steady winds you could combine the two methods of generating income. Wind power can be a positive addition to land that is not useful for a lot of other things.
Ridge tops with sporadic gusty winds can be disastrous.
In the mountains of North Carolina there have been attempts to have large wind turbines on ridge tops and the results have been the props being torn off in high wind storms. Gusts in storms can be pretty dramatic here.
To put it in perspective, we live at 3000 feet on the side of a mountain and we were required to build our small house to specifications that could stand up to 120 mph winds in order to meet building codes and legally occupy our home. A true ridge top can see some high winds indeed and has little wind breaks around them.
Noise levels may be a bit much for some.
Wind turbines are not silent when in operation. The more you have and the larger they are the more noise you can expect. If you and others live close by the noise might combine to an unpleasant level. You can expect a noise level of up to 60 decibels with a single turbine. Even if the actual level of noise is not too much for you, the consistency of it is also something to consider.
Wind power is a good supplement to other power systems.
A lot of people have a wind turbine but they also have a solar power system. This allows for wind power to kick in and charge batteries faster when there is wind but the user has the solar system for more reliable power. This can be a good way to go about it if you like the idea of some wind power but know that it is not consistent enough to rely on for major daily energy needs.
Can require significant clearing of land.
A serious wind turbine farm could require quite a bit of land clearing which can have a whole array of environmental consequences. Even if you want just one turbine if you have a lot of trees and not much clear space you may be looking at a larger logging operation than you bargained for.
Assessing Your Property For Wind Power
One of the first steps is just to be honest with yourself about how much wind you get at your place. Specific data for your area may be available from nearby weather stations. Wunderground is a good source of small independent weather stations that can provide useful information.
Some areas have so many micro climates that this data might not be quite as useful as in some areas. I know where I am at on the mountain makes for different climatic conditions than those a few miles as the crow flies. We often have snow melt off fast while the snow stays on the ground for days longer sometimes up the road from us.
Snow and ice can damage turbines.
Ice can accumulate on turbines and cause damage. If you have a lot of ice storms in the winter you need to think about that. Some people simply take the prop off their turbine if they know a lot of inclement weather is on the horizon.
There is nothing wrong with some seasonal wind power if that is what you have to do but it does make it seem like a slightly less good deal than something you can use year round. Solar panels stay warm enough to withstand some levels of snow and ice.
If you don’t have much experience with renewable energy produced at home then starting small and learning as you go could be a good move. You can always get a bigger turbine later.
There are advantages to small ones because they can be placed more easily in neighborhoods and do not require as large of a structure to support them. This gives you a chance to see how well it will work on your place before investing in a larger turbine.
Putting together a turbine is not difficult but you do want to make sure everything is well secured. A prop or other parts flying off in any direction could cause serious injury or damage surroundings.
It doesn’t take much of a gust of wind to cause a problem if something is not secured well. Take your time and do not get in a hurry.
Turbines are low maintenance not no maintenance.
Once you have a turbine set up it can be easy to just roll with it and let it do its thing without thinking about maintenance. Occasionally you should go over your turbine and make sure that nothing has worked its way loose or become damaged in any way.
This is especially important if your prop has been exposed to any extreme weather systems. It is better to take a few minutes to check things out rather than risk more serious damages or create a safety hazard.
Saving money on set up.
There are ways to save money on some of the set up costs. For example you could mount a small turbine on the roof of your house rather than constructing a tower. This also means your turbine is not taking up other space on your property and is well out of reach of kids or animals climbing on it.
Just doing it yourself is going to save you a ton of money compared to what an energy expert from a solar installer or similar will charge you.
The problems with professional renewable power system installation for residential use are numerous. A contractor is likely to install your system a specific way that is designed to just feed power back into the grid.
This results in a system where the grid tie box shuts down your system when the grid goes down because they do not want you feeding power back into the grid when there is an outage. The logic is that repairs to the grid requires no current that could shock crews or harm equipment.
There is no battery back up in a typical grid tie system. This means you are kind of defeating the purpose that probably led you to wanting a renewable energy system in the first place.
A separate smaller system or the possibility of a hybrid system of sorts are your options for grid down power. Perhaps there are contractors out there that will be more flexible in regards to the system they install. The important thing to remember is that if you hire a contractor for any renewable energy work you need to be very clear of what you want so they can tell you if it is even possible or legal.
Any system that is beyond the normal needs to be discussed throughly and planned out well to avoid disappointment or added unforeseen expenses in the future.
Generating revenue from your home system might not be as feasible as you think
The advantages of a grid tie system is that you may be able to generate enough power to get revenue paid to you. Rates vary widely. Grid tie boxes are not cheap to install. In my home state of North Carolina the power companies destroyed any chances of solar or any form of renewable energy such as wind paying back the customer in a reasonable amount of time.
Rates paid to those feeding back into the grid were reduced from $0.09 a kilowatt hour to a paltry $0.01! This was a big financial hit for those that had already made an investment in greener and more sustainable energy for everyone.
Having to maintain a separate back up system is not something some preppers are prepared for.
Then you need to add in the cost of having a smaller separate system for your own energy needs for when the grid is down. Power companies have a lot of control over that main system because it is illegal to send power back into the grid without their approval.
Sorting through the legalities and troubleshooting grid tie set ups
I have just touched on some basics about a very complicated subject. It is essential that you check with your local power company and learn the rates and rules in your area if you want to sell power back. A major renewable energy system is a big investment for most us and deserves the due diligence required to make a well informed decision.
Wind turbines are affordable and you can even make your own
There are some very creative folks out there that have made their own turbines. If you don’t want to fool with all that though you are in luck because turbines are very inexpensive.
Energy from wind is one of the cleaner energy sources you can harness.
Wind energy is definitely less polluting then the coal fired power plants and nuclear options out there and doesn’t generate a ton of waste.
Choosing Your Starter Turbine
I spent some time looking at various turbines and came to the conclusion that a lot of the lower priced ones get some pretty negative reviews. What this says is that while the cost of turbines seems to have went down, it has opened up the market to include some real garbage that is going to be frustrating to say the least.
I would say plan on spending at least $500 on a turbine and $1500 if you want something large. The price seems to be about $0.60 to $1 a watt for any turbine that has a decent level of customer satisfaction. This budget includes some of the extras you will need. On Amazon there is a kit that caught my eye because it is such a good deal for a prepper’s starter renewable energy system.
ECO-WORTHY 24 Volts 600 Watts Wind Solar Power: 12V/24V 400W Wind Turbine + 2pcs 12V 100W Monocrystalline Solar Panel + 24cm Cable with MC4 Connector
This is a fantastic deal for those that want to play with several power methods and keep costs down. It is amazing that shipping is also included in this cost. When we bought our panels the shipping costs were significant. I like this kit because it gives a prepper options. If the wind is not going you still have the solar panels to provide you with some backup power.
You do of course need to buy one or more batteries and a pole or something to mount your turbine one so there are some additional expenses to consider.
Popsport Wind Generator 400W Hybrid Wind Turbine Generator DC 12V/24V Turbine Wind Generator 3 Blades Light and Powerful Wind Generator Kit for Home Use
This little turbine caught my attention because it gets at least a few good reviews and it is affordable for those that want to start their exploration of wind power. The small size makes it realistic for a small residential application such as your porch roof. The super low cut in speed is worth noting too.
This is not a turbine I would trust in places that get extremely high winds as it is really just made for small scale use but for some folks it is an excellent start.
Conclusion: Wind energy can work in the right place
Look around you and see what others are doing for renewable energy. Areas like the midwest may be an excellent place to harness some wind power. Parts of Texas are particularly well suited. Down here in the southeastern US solar is a better option for a lot of us. Go down to the coast where there are some steady winds and that can change.
When it comes to renewable energy, success is dependent on people realizing the uniqueness of their climate and topography and going with the system or combination of systems that makes the best use of time, money, and resources. There is no one size fits all renewable power system.
