Natural gas generators usage should generally increase as it is the cleanest burning fossil fuel. Compared with oil and coal, natural gas generators produce lower emissions of nitrogen, sulfur, and greenhouse gasses like carbon dioxide. Natural gas generators also do not produce a pungent odor like a gasoline or diesel fueled one would. For people with homes powered with some natural gas, the comparison of the gas bill and the electricity bill will definitely show how much cheaper gas is. Even though natural gas electricity generation is used much less in homes, mainly for ranges, oven, heating water, and others, a natural gas generators can save up to 40% more than gasoline and diesel.
Now that we know natural gas generators are cleaner and cheaper, it is not hard to see that they are more efficient. For residential and business electrical power generation using natural gas, the fuel supply is already supplied and there is no need to purchase extra fuel and store it. Gas lines are already in place, delivering natural gas that can be used by power generators. For a portable natural gas generators, fuel storages similar to propane tanks for many barbecue grills can be bought and transported fairly easily to remote areas to provide electrical energy.
Natural gas is a very efficient fuel for powering emergency or portable generator. When it comes to providing power at an affordable cost, natural gas is probably the best for non renewable resources.
Although natural gas is not the perfect fuel replacement, it is a good cheap and clean alternative that should rise significantly in generator usage.
