Portable power generator are a type of whole house generator. Such generators can supply electricity to the house even in the case of a power outage. So it would be quite easy to keep using essential appliances, like heaters, air conditioners, lights, and refrigerators, even when the power is out.

These electric generators convert mechanical energy to electrical energy. There are two kinds of such generators – stationary power generator, and portable power generator, which are in fact electromagnetic generators. They run on many different fuels, like natural gas, gasoline, diesel, and even liquefied petroleum gas. You would be pleased to know that the gasoline portable power generators are quite cheap – for instance, you might be able to get a 3000W set for as less as $300! Also there are other cheap options to produce green electricity such solar power generators, wind power generators and small but efficient Solar Battery Chargers for personal use.

But it is important for you to know that the device has short run-time. You would have to refill the tank many times a day, if you are running them continuously, at rated load. Portable power generators are also quite unsuitable as a long-term power back-up solution, since their gas pumps may not work during a blackout of massive proportions.

A portable power generator must be rolled out from the storage, hooked up to a fuel line or filled with fuel, and then manually started, and connected to the loads. Portable systems are quite easy on the pocket, in fact they are much cheaper than the standby models – and they don’t even require professional installation.

The portable generator offers less power levels than the standby systems. This makes them the second choice in the case of a long-term emergency.

What are the factors you should look into while choosing a portable power generator? You should consider the wattage, the cost, the duration of time you are likely to require emergency power, the availability of fuel, the safety, and also the convenience of use.

You can buy a portable power generator online – you would get a broader selection, lower prices, and if you’re lucky – no sales tax. Amazon’s Home Improvement Department offers great discounts, and a wide range. Plus, you wouldn’t be required to pay any shipping charges.

While on the subject of portable power generators, did you know that there is one kind, that uses trash as its primary fuel source? Yes, this unique power generator has been developed by scientists, is about the size of a small moving van, and it can process many types of refuse – like plastic, cardboard, food waste, paper, Styrofoam, and woodchips. It’s a very promising technology, and the bio-refinery uses two different process for the creation of fuel.

Foot material is separated by the machine into a bioreactor, which uses the yeast ferments to create ethanol. The other materials go to the gasifier, and they are converted into methane and propane gas – these fuel the diesel engine, and voila, electricity is created! The system is designed to run on diesel oil for many hours, until the bio-reactor and the gasifier start to produce fuel. Such a generator is an environmentally friendly alternative to traditional diesel generators, and using biomass as a fuel causes much less pollution, because carbon dioxide is absorbed by the plants.
