Should You Get a Natural Gas or Diesel Generator?

Good question. There are many advantages to both sides of the coin. It all depends on your budget, your intended usage, your business requirements and your personal preference. To figure out which type of generator in Alberta is best for you, we’ll go over the pros and cons of each.

Natural Gas Generators

This type is efficient at generating power, used for both emergency and portable generators in all sizes of businesses.

Why Get One?

Natural gas generators:

  • Are extremely efficient.
  • Are cleaner than other fuels.
  • Cost less than other non-renewable fuels.
  • Have lower emissions of sulfur, nitrogen and carbon dioxide in comparison with oil and coal
  • Are one of the cleanest burning fossil fuels.
  • Have no pungent odors, unlike generators powered by oil or diesel.
  • Help to reduce costs when used to power homes and businesses.
  • Are readily available in large cities due to the fact that it is directly delivered through pipelines.
  • Are easy to store in terms of fuel.

Why You Shouldn’t Get One

Natural gas generators:

  • Are extremely explosive, resulting in a fire hazard in the event of a burst pipeline.
  • Are more expensive to run compared with diesel generators.
  • Emit more greenhouse gas, specifically carbon dioxide.
  • Use limited or non-renewable energy resources.
  • Can result in lack of fuel when you need it most, as the supply of natural gas is disrupted during times of natural calamities due to the fact that it is supplied through gas pipelines.

Diesel Generators

There are two components to these generators: a diesel engine and an electrical generator. They both give power to areas that have no access to a power grid or they can act as a backup due to power outage. Diesel generators are common as back-up units for emergency power supplies, used in both small and large establishments, homes and offices.

Why Get One?

Diesel generators:

  • Are cost effective overall, although more expensive than natural gas. However, you get more energy out of diesel.
  • Are energy and fuel efficient.
  • Provide a steady power supply, good in places where life or death situations occur, such as in hospitals.
  • Are sturdy and reliable.
  • Are less noisy.
  • Do not require wires or spark plugs, which helps to cut maintenance costs.
  • Enjoy a longer lifespan than a natural gas engine.
  • Are less flammable than other fuel sources.

Why You Shouldn’t Get One

Diesel generators:

  • Are expensive in comparison to other generators but have lower maintenance costs which can make up for that investment.
  • Can be noisy, although new models are much quieter.
  • Are bulky, with large and heavy components vs. smaller and lighter generators; not the best in terms of portability.
  • Are considered to be a major pollutant.

Wrapping it Up

In conclusion, when you must choose between diesel and natural gas generators, you first have to answer these two questions:

  • What is the main purpose for your need for a generator?
  • How much can you pay for the unit?

Both natural gas and diesel generators have their good and bad features…the one you choose will depend on your unique needs. With the advancements of biodiesel coming to the forefront, a more eco-friendly alternative to both of these will likely bring more diesel/biodiesel generators to market.
