For many years, diesel generators have held a disproportionately large percentage of the generator business. While diesel generators will continue to be a backup or even a major source of electricity for millions of people, another form of generator is catching the attention of more and more operators today. Natural gas generators are a cost-effective and efficient alternative to diesel and gas generators. These devices, whether portable or fixed, standby or prime, may provide the power needed to accomplish everything from keeping the TV on in your movie room to keeping factories operating and saving lives in hospitals when called upon.
