A good generator can seem like a frivolous expense when things are going well, and you have all the electricity you need from the local power company. But when emergencies occur and outside power isn’t available, you’ll be glad you have a generator to provide needed power, along with plenty of fuel to run it. Generators come in all shapes and sizes, producing a wide range of electricity outputs. Not just any generator will suit your specific needs, so shop carefully. To choose a generator that’s right for you, educate yourself on capacity, size, noise output and other important factors.
