If you have ever been without electricity, then you know that it can be an added expense if you have to replace any food that may have spoiled, etc. That is why having a standby generator can be a very handy machine to have around. The sale of small portable generators is constantly rising as is shown when you consider that there were approximately 3 million sold in 2007 and the sales by 2011 is expected to be around 7.1 million.

Electricity is one of the most important necessities in today’s society, and being without it may result in work stoppages in industrial and commercial establishments, as well as causing a great deal of discomfort on the home front. For regular consumers, home generators can give a little extra peace of mind.

There are, of course, several different brands and types of backup generators, all with their own features and uses. Some use different fuels or differ in the amount of electricity they can produce. You would not want to use an industrial sized standby generator in your home, as it would be too large and very expensive to use. If you basically want one to run lights or small appliances, then a small, portable home generator should suffice.

If you intend to use a backup one for powering major appliances, then you should opt for a larger one that can handle larger electrical demands. Also keep in mind that you will need to choose the source of power for your generator, such as diesel, gas, natural gas and propane. With diesel generators you will have fewer expenses, but they can be fairly noisy. The portable power generators that use propane are cleaner burning.

When you lose electricity your main goal is to restore power as quickly and easily as possible, thereby minimizing the amount of your loss. If you live in a rural area, then there is a good chance that the generator could be difficult to get to, especially if you need to get power restored as soon as possible in your barn where animals may be.

In that case, many people prefer an automatic standby generator which, as the name implies, will start automatically in the event of a power failure, saving a good amount of time and work that may be involved. Having backup, emergency generators such as this will make you feel much safer, will get your lights on as soon as possible so that you may tend to other things that may occur with a power outage.
