Natural Gas Generators – The Best Reviewed

In recent years, natural gas generators have become more and more common. In the past, they have been avoided due to lack of technology. They were not able to burn fuel as well, were not as durable, and technology did not exist to burn the gaseous fuels sustainably.

The concept of natural gas generators is exactly the same as those that run on gasoline. They are still powered by internal combustion engines but mix natural gas with air instead of gasoline. It is commonly found that natural gas generators are also able to run on propane gas.
