Generators are becoming increasingly popular as more people need power to run their homes and businesses. Whether you're experiencing a power outage, planning a camping trip or you work in a remote area, a generator can be a lifeline. However, before you invest in a generator, you should weigh up the pros and cons. Read on to find out the key points so you can make an informed decision.

What is a Generator and How Does it Work?

If you're not familiar with generators, it's worth starting with the basics. A generator is a device that converts mechanical energy into electrical energy. This is done by spinning a coil of wire around a magnet. The movement generates an electrical current. A generator can be powered by fossil fuels such as gasoline, diesel, or propane, or sustainable energy sources such as solar power.

Pros of Using a Generator

There are several benefits to using a generator, including:

  1. Convenience: When you lose power, a generator can provide a quick and easy source of energy. You won't have to wait for the electricity company to restore your service.

  2. Security: A generator can provide extra security during power outages. If you live in an area that's prone to blackouts or natural disasters, you can be confident that you'll have a reliable source of energy.

  3. Versatility: Generators can be used in a range of settings, from construction sites to campsites. They're also handy if you're running a mobile business or event.

  4. Cost-Effective: A generator can be a cost-effective way of providing electricity. Often, it's cheaper to run a generator than to install a complex electrical system, particularly if you only need power for short periods.

  5. Emergency Backup: A generator can be a lifesaver during an emergency. Whether it's a winter storm or a medical emergency, a generator can help keep critical equipment running.

Cons of Using a Generator

While there are many advantages to using a generator, there are also some drawbacks. These include:

  1. Polluting Emissions: Fossil fuel generators can generate noise and pollution, which can impact the environment and your health.

  2. Fuel Costs: Fuel costs can quickly add up, particularly if you're using a generator for long periods.

  3. Maintenance: Generators require regular maintenance to ensure they're in good working order. This can involve oil changes, fuel filter replacements, and other tasks, depending on the type of generator you have.

  4. Safety Concerns: Generators can pose safety risks if they're not used properly. Carbon monoxide poisoning and fire hazards are just some of the risks associated with generator use.

Different types of generators

Generator Type Pros Cons
Portable Easy to move, lightweight, and perfect for camping or emergency use. Less powerful than other types of generators, may require frequent refueling.

Generator Safety and Maintenance Tips

Generators are a fantastic source of backup power, but they can also pose safety risks to individuals who do not use them properly. Due to the potential safety hazards, it's important that safety precautions are taken when operating a generator. In addition to safety precautions, there are also routine maintenance that are critical to ensuring the long-term safety and functionality of the generator. In this section, we'll review some safety and maintenance tips to help keep you and your generator working safely and efficiently.

Safety Precautions:

  1. Proper Placement: Place the generator on a level, dry surface that's away from combustible materials such as wood, paper, or gasoline. Make sure there is adequate space for proper ventilation and that the exhaust is directed away from occupied areas. Also, ensure your generator is placed at least 10 feet away from doors, windows, and vents as exhaust fumes can be dangerous.

  2. Grounding: Ensure that the generator is grounded properly to prevent electrical shock. Use a grounding rod or grounding method as prescribed by the manufacturer to ground the generator.

  3. Ventilation: Never use a generator indoors, even if windows and doors are open. Make sure your generator is kept outside and away from windows, doors or vents. Ensure there is proper ventilation at all times, and that the exhaust flow remains unobstructed.

  4. Electrical Safety: Keep the generator dry at all times to prevent electrocution. Operate the generator in dry places and do not operate if standing in water or on wet surfaces.

  5. Refuel Safely: If you need to refuel the generator, turn it off and allow it to cool for at least 5-10 minutes before adding fuel. Never refuel the generator while it's running or hot.

Maintenance Tips:

  1. Check the Oil Regularly: Oil is the lifeblood of your generator's engine, and without it, the engine will seize up very quickly. Change the oil every 50-60 hours or as prescribed by the manufacturer.

  2. Check the Filters: Filters help keep your generator's engine clean, and help prevent damage from airborne debris. Clean or replace the air filter as prescribed by the manufacturer.

  3. Inspect the Spark Plug: The spark plug ignites the fuel in the engine. Check and replace the spark plug as per the manufacturer's instructions.

  4. Keep Fuel Clean and Dry: Fuel is an essential component of the generator. Always use clean, fresh gasoline or diesel fuel and add a fuel stabilizer to prolong its life. Store fuel in a cool, dry place, ideally in an approved EPA fuel container.

Generator Cost and Buying Options

Generators can range in price from a few hundred dollars to thousands of dollars, depending on the power output, fuel type, and brand. When choosing a generator, it's important to consider the initial purchase price alongside ongoing fuel and maintenance costs. In this section, we will explore the different cost considerations associated with purchasing a generator, as well as where to buy a generator.

Initial Purchase Price

The initial purchase price of a generator is often the first consideration for many buyers. As mentioned, the cost of a generator can vary greatly depending on factors such as power output, fuel type, and brand. Portable generators with lower power outputs typically cost less than larger standby generators, which can cost upwards of $10,000 or more.

When considering the initial purchase price, it's important to think about what type of generator will best fit your needs. A smaller portable generator may be sufficient for powering essential appliances during a power outage, while a larger standby generator may be necessary for those who live off-the-grid or require a more reliable source of backup power.

Ongoing Fuel and Maintenance Costs

It's also important to consider the ongoing fuel and maintenance costs associated with operating a generator. Generators run on a variety of fuels, including gasoline, diesel, propane, and natural gas. The cost of fuel can vary widely depending on the type of fuel used, and how often the generator is used.

In addition to fuel costs, generators also require regular maintenance to keep them working properly. Maintenance tasks may include oil changes, filter replacements, and other routine checks. Some generators require more frequent maintenance than others, and the cost of maintenance should be factored into the overall cost of owning a generator.

Buying Options

When it comes to buying a generator, there are several purchasing options to consider. Online shopping allows buyers to compare prices, features, and reviews from a wide range of sellers.

Another option is to buy a generator from a specialty generator dealer. These dealers often have a wide range of generators available, and can offer expert advice on choosing the right generator for your needs. Additionally, they may offer installation services and ongoing maintenance plans, which can be helpful for those who are new to using a generator.

Finally, generators can be purchased from home improvement stores such as Lowe's or Home Depot or online stores like Amazon. These stores typically have a range of portable generators available for purchase, and often offer installation and maintenance services as well.

FAQs About Generators

What size generator do I need?

The size of generator you need depends on your energy requirements. A small camping generator might produce around 1,000 watts, while a home generator can produce up to 20,000 watts or more.

How long will a generator run on a tank of fuel?

Again, this depends on the size of the generator and its fuel efficiency. Some models are designed to run for several hours on a single tank of fuel, while others may need refueling every few hours.

Can you use a generator indoors?

No, generators should not be used indoors due to the risk of carbon monoxide poisoning. Always ensure that you use your generator in a well-ventilated area.

However, newer type generators are becoming more and more safe.
