Generators convert diesel or gasoline into electric power. They can be large enough to support the power needs of a small community or small enough to enable someone to listen to the radio while camping in the woods. The amount of wattage determines the type of use the generator will facilitate: 1000 watts can provide power for fans, TVs, radios, small power tools and small appliances; 2000 watts will provide power for microwave ovens, larger power tools (circular saws) and larger appliances that are resistive load (like coffee makers and toasters); 3000 watts will operate a small air conditioning unit; over 4,000 watts will generally provide the energy for a home during a power failure, like a storm or other types of natural disasters. Larger wattage, like 8,000 watts will provide much longer amounts of power for a home in the event of a power failure. Generators are marketed in several ways. “Quiet” generators are advertised to be used in settings where a noisy generator matters, like at a camp site with others nearby or at an outdoor event where a power source is needed, but should not be too loud for the performer or the movie being shown, etc. Industrial generators are geared for use at construction sites or for situations where a generator would be rented for temporary use. Economy generators are usually smaller but louder generators. Finally, the higher end generators that are not for industrial purposes are marketed to families who would use them as a power source back up in the event of a natural disaster. Prices for generators range from about $300 to several thousand. A family that would choose to purchase one as a back-up power source can expect to pay $500 to $800. Safety with generators is important: they must be used in outdoor spaces as they produce toxic carbon monoxide. They can cause fatalities in confined spaces.
