• Natural gas is one of the cleanest fossil fuels when it burns as the emissions of sulphur, nitrogen, and carbon dioxide are considerably lower, in comparison to oil and coal.
• One of its advantages can also be regarded as a disadvantage. Since natural gas is supplied through gas pipelines, at times of natural calamities the supply of natural gas is disrupted. As a result, one might face a power down situation with lack of fuel, in a situation where you need to operate your generator the most.
Diesel generators are extremely common as back-up units for emergency power supply. Here are some advantages and disadvantages of them.
• While diesel is considerably more expensive, it also has a higher energy density. So while you may pay more for the diesel, you will also get more energy out of the diesel than you would for the same volume of gas. Hence, fuel efficiency is by far the single most important advantage of diesel generators.
• Diesel generator can be considerably expensive in comparison to other generators.
