Creating Efficient Home Energy Generation Systems

When you are tired of paying for your high home energy bill month after month and would like see some changes and feel some savings, there is one thing to do: invest on one or more alternative home energy generation systems.

Home energy generation is the solution if you want to cut down on those bills and utilize the natural energy sources all around you. A home energy generation system will provide you what is essentially home energy freedom. Sure, you have to invest first but for many it is worth every penny. You can spare yourself from the present costs of home energy and the future increases that may occur. And most of all, investing in a home energy generation system will also help the environment through the use of cleaner sources of energy.

Among the types of alternative energy that can be used in the home, wind energy and solar energy are the most common.

1. Wind Energy

Wind is very abundant in many parts of the country; thus, many households can capitalize on the use of wind as a source of home energy. As the cost of energy production through fuel and oil grows increasingly high, clean, safe and free air appears to be the better choice for the future.

As a main source of power for your home, wind can provide substantial cost savings over the use of energy sourced from the expensive oil. However, wind speed varies on a daily basis. One day, the wind may blow hard all day long. The next day, the wind may not be able to even make your turbine spin. And even in the breeziest places in America, you can never tell when you're going to get a windy day. This is one disadvantage of using wind power, but wind patterns do exist. Assessing the wind patterns in your area can help you determine whether a wind turbine will be a useful source of energy for your household.

If you are planning to install wind turbines on your home, make sure that the local zoning allows wind turbines. You must also ensure that there is a good source of wind on most days. A wide and open space, at least 1 acre, is ideal for wind turbines. But, if you do live in a windy area, and are paying more than $150 on your monthly electric bill, then wind power may be a good option for you.

There are 5 main components of a wind power generation system.

1. The rotor is the set of rotating blades designed to capture the air.  The rotation brings power to the generator.

2. The turbine or the generator is attached to the rotor. It stores the energy that the home will use.

3. The tail is located opposite of the rotor. It tracks the direction of the wind.

4. The tower raises the turbine, rotor and tail up into the air to receive the most amount of wind possible.

5. The governor is the mechanism that controls the production of energy. This is like the transformer you can see on electric posts.


2. Solar Power

There are 6 often-overlooked advantages to installing solar panels on your roof - over other energy generation methods.

1.  Solar panels are lightweight, safe, and usually easy to install.

2.  Roofs are susceptible to UV exposure. The solar panel eliminates this. Your roof will also be protected from weather.

3.  Solar panels contribute to keeping your house well insulated. They provide extra covering and enable you to save as much as 30% on heating expenses.

4.  Drilling holes in your roof to install a wind turbine or other generator is very risky. Interlocking solar panels eliminate this risk.

5.  Solar panel designs can work on almost any roof type and size. In other words, you can get the perfect solar panel no matter what the size and shape of your roof is.

6.  Solar panels are installed without requiring you to modify your roof.

Solar power can help you cut down the cost of your electric bill tremendously. If you live in a sunny climate (even if it's cold), solar power can be an excellent choice for a home energy generation system.

New Uses for Solar Power

When you think of solar power you probably think of heating and light for your home. That is one of the many things that we use solar power for.  Solar power is everywhere and its use is growing every day. There are many different products that are made using solar power. Solar power means using the sun's natural heat to produce electricity, heat, and more.  When you use solar power you are using a natural and abundant resource that we cannot deplete, and which causes no pollution (other than the making of means of storing and processing this energy - which continues to become ever more efficient).

There are more products that use solar power than what we realize. A lot of today's electronics use some type of solar power in order to function accurately.  Calculators are a prime example of a useful solar power product.  These calculators may or may not have on and off switches.  Some rely on the solar panel completely in order to stay or turn off.  Solar power calculators need a certain amount of light inside the solar panel in order to turn the calculator on and perform what you want it to do; add, subtract, divide, multiply and more.  The solar panel in a calculator is obviously not as big as the one that you would to power your home.  The size needed for a calculator is adjusted before installation to provide the amount it needs. Solar power use can also be found in travel products, outdoor recreation, safety products, emergency products and more. 

Solar power radios are produced with a solar panel inside that transforms the sunlight into energy allowing you to listen to your radio while you are outside.  You may also find solar power in flashlights, battery chargers, mobile phone chargers, watches, lanterns, emergency products such as sirens and lights.  As you see there are a number of products that are already using solar power technology.  Portable solar chargers are great because they charge the product that you have using just the sunlight, and they are very easy to use.  Camping equipment and supplies also work well with solar power because sunlight during the day then helps to supply lanterns, flashlights and radios at night.

Cooking outdoors can also be done by using solar power to heat the element that will ignite and allow for even cooking.  Because more people are turning to solar power for their main energy source there are more and more companies that are marketing products that are produced using solar power.  Appliances are being made specially for solar power homes.  Many new appliances such as refrigerators, stoves, dishwashers, and more will work great in a home that is generated by solar power.  They are built to conserve energy and operate very efficiently.

As the demand for more efficient and clean energy grows, the availability of solar powered appliances and electronics will grow as well. We can look forward to seeing more interesting innovations in this field in the years to come.

How to Choose the Right Solar Power System for Your Home

With energy costs rising steadily, more and more people are seeking ways to incorporate solar power into their energy plans for their household. However, there are some things to bear in mind if you want to install a solar power system in your home. Not just any system will do. It needs to fit your energy needs and your property location. Here are some tips.

First, determine if your location is conducive to solar. You need to have an area of your property that faces in a southerly direction - ideally, it will face directly south, but slightly southwest will work. It needs to receive sunlight between 9AM and 3PM. Make sure you observe this area all year round, because a property's sunlight can vary greatly from season to season.

Remember, too, that you can mount solar panels on tall poles and trees, not just your roof. So if an area of your property is shady during the key part of the day, look up - it might be sunnier up higher.

Second, call your utility company and find out what your average monthly use of kilowatt hours is. Then you can determine how many KW hours your solar system will have to generate. (You might choose to have only half of your KW hours replaced by solar.)

Types of Home Solar Systems

In order to narrow down what sort of system you need, it's important to familiarize yourself with the different types. Most homeowners choose to be tied in to the power grid, because a stand-alone system can get very complicated and expensive. It is an option, however.

These are what most people think of when they think of solar power. They are flat panels that sit on your roof. Generally, photovoltaic systems can power appliances and lights only, not heating and cooling.

The power generated is usually tied in with the conventional power grid, and this is viable option for most solar power users. If you are tied in to the grid, you do not need a battery back-up for night-time and other times when the sun is not shining. The conventional power company becomes your back-up when you are tied to the grid.

2. Solar heating systems

There are active and passive solar heating systems for our home. Passive solar heating uses conduction, convection, or radiation to move sun-generated heat throughout the home. Active solar heating collects the sun's heat in some kind of air or water reservoir, then pumps it throughout the home.

Obviously, depending on the system you choose, these are usually less costly and easier to set up and maintain than a solar panel system. You may choose to go less intensive and just use passive or active solar heating, or you may add solar panels as well and reap the benefits of a combination of these systems.

Solar Rent Lease and Power Purchase Agreement (PPA) Strategy – An Explanation

If you're looking to equip your home for solar power, but not sure how to start, or if it's too expensive, there are some new options available now that many people are not aware of. As alternative power comes to the fore, programs are springing up to facilitate the use of alternative energy in people's homes and businesses. Solar rent leases or power purchase agreements (PPAs) are two of those programs. Here is how they work.

Image via WikipediaSolar Rent Leases

A solar rent lease involves renting solar equipment from a power/electricity provider. The provider actually owns the solar panels and overall solar power system, and is responsible for its maintenance. You pay a fee, or rent, for the use of the equipment. Generally, the solar power system is intended to augment, not replace, the electricity you purchase from your utility company. Hopefully, you will save so much on your power bill that it will offset the rent amount.

Most power providers that offer solar rent leases have a contract that "locks you in" to the agreement. It has advantages for you, the purchaser, and the provider - you are protected against rising utility rates, and the provider gets the security of a long-term contract. Most providers' contracts are for 15 to 20 years.

PPAs

A power purchase agreement is similar to the solar rent lease. With a PPA, the provider purchases the solar panels and solar power system, and also installs and maintains them. Instead of paying rent, you, the purchaser, pay for the actual power generated by the solar power system. Again, your monthly utility bill will be augmented, not replaced, by the solar-generated electricity. The idea is for the purchaser to save money and reduce his or her use of fossil fuel-generated electricity.

Image by U.S. Army Environmental Command via FlickrPPAs also involve a contract, usually 15 to 20 years. Some PPAs give you the option of buying the equipment and solar power system when the contract ends.

Generally speaking, the electricity providers involved in solar rent leases and PPAs are independently owned companies. Thus, PPAs and solar rent leases help finance these independent power producers. Because the electricity output is clearly defined and measured and there are contracts in place, banks and other financial institutions are more likely to invest in the independent provider. This is another incentive for some who are interested in alternative energy.

Another attractive thing about PPAs and solar lease agreements is the low initial cost. Many people would like to "go solar" but are unsure how to pay for, install, and maintain the necessary equipment. With these agreements, the provider does all of that and you only have to pay rent for the equipment or pay for the solar power generated.
