A propane generator is an excellent way to go for many uses from recreational to residential. Small businesses that need a portable electricity solution can use propane instead of gasoline as a more environmentally friendly option. It can also be set up as a standby emergency generator.
Propane is made using natural gas crude oil refining. It burns with less emissions than liquid fossil fuels such as gasoline and diesel. Propane is actually stored in a liquid state and as it returns to a gas it evaporates out of the tank, causing the outside of the cylinder to frost up during heavy usage. These propane cylinders are easy to get refilled and safe to store away from sources of ignition and combustibles. Gasoline is known to have a fairly limited shelf life, unlike propane which will be fine for quite a long time unused.
It is important to note that using propane still introduces carbon dioxide into the atmosphere, just less of it than with gasoline and diesel. For this reason a propane generator could be considered less harmful to the environment, although not a perfect solution.
A propane generator can provide reasonably efficient energy output compared to cost and can be set up to run over a long period of time using a large household supply tank. A large propane generator would be capable of supplying the electrical needs of many appliances at once, as a standby generator for use in a power outage or emergency. Since many homes have propane tanks in use for water heaters, kitchen stoves, outside barbeques and home furnaces, it is not too much of a stretch to imagine installing an emergency propane generator that would be activated on a moment's notice.
