If you feel like power outages have become more frequent in recent years, you’re right. Between 2014 and 2023, the U.S. experienced twice as many major outages as in the previous decade.* As a result, many people are turning to home generators to provide power during emergencies, but before heading to the hardware store, understand that these are not one-size-fits-all appliances.
Additionally, while generators are helpful (or even lifesaving) in emergencies, they can be dangerous if not used properly. Remember that you may be working by flashlight in severe weather when you need to power up your generator, so it’s critical that you read the instruction manual and safety guidelines ahead of time. Most importantly, practice operating it before you need it.
There are four main types of generators to choose from:
Home standby generator. Also known as a whole-house generator, this is the most expensive option, but it provides the most power and is the easiest to use, because it starts automatically whenever power goes out. These are fueled by natural gas, propane, or diesel, and they’re more powerful and reliable than portable generators. However, because they are permanent fixtures, they’re subject to municipal permits and regulations on noise restriction and location. As such, they should be installed by a professional, and installation typically costs more than the generator itself.
Portable generator. With a lower cost and no installation expense, this is a more affordable option, but it has some risks. It runs on gasoline or a combination of gasoline and propane, so you’ll need to keep a stock of fuel on hand. Additionally, it can’t be used in an enclosed space and must be positioned carefully outdoors to avoid carbon monoxide entering the house.
Inverter generator. These also run on gasoline, but they are quieter than portable generators and produce fewer emissions, because they have more sophisticated engines that adjust depending on how much power is needed. However, they can cost more than portable generators.
Portable power station. This is essentially a large, rechargeable battery that doesn’t need fuel. You charge it by plugging into an electrical outlet or (in some cases) by using a solar panel. It doesn’t run as long or provide as much power as other generator types, but it’s the only kind that can be used indoors, so it’s useful if you live in an apartment.
This is just a broad overview, and to find the right generator for you, you’ll need to look into your home’s power needs, the full pros and cons of each generator type, safety features, and cost (including installation fees as needed). So, don’t wait until a storm forecast and try to rush this purchase. Make this part of a carefully considered home safety plan that will prepare you for any emergency.
