Q: Are generators safe?

• <div><p>When installed and used correctly, generators are safe to use. The <a href="https://www.angi.com/articles/power-out-3-tips-safely-operate-home-generator.htm">most critical generator safety tips</a> to keep in mind are:</p><ul><li><p>Never use a portable generator inside an enclosed space, as the carbon monoxide exhaust it creates is lethal.</p></li><li><p>Never attempt to connect your generator to your home&rsquo;s electrical panel independently; hire a professional for this dangerous job.</p></li><li><p>Never overload your generator by connecting more appliances than for which it&rsquo;s rated; you can damage your generator and appliances or even cause a fire.</p></li></ul><p></p></div>

Q: What types of fuel do generators take?

• <div><p>Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:</p><ul><li><p>Natural gas: $2,000&ndash;$21,000 per year </p></li><li><p>Liquid propane: $2,000&ndash;$21,000 per year</p></li><li><p>Diesel: $3,000&ndash;$20,000 per year</p></li><li><p>Gasoline: $500&ndash;$3,000 per year</p></li><li><p>Solar generator: $2,000&ndash;$25,000 per unit</p></li><li><p>Battery backup: $10,000&ndash;$25,000 per unit</p></li></ul><p></p></div>

Q: Can a 10,000-watt generator run a central AC unit?

• <div><p>A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.</p></div>

Q: Can you use biofuel in a whole-house generator?

• <div><p>In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.</p></div>

Q: What size generator do I need for my house?

• <div><p><a href="https://www.angi.com/articles/what-size-generator-do-i-need.htm">Generator size requirements</a> vary wildly among properties, but typical generator sizes are listed below based on home square footage:</p><ul><li><p>1,000 sq ft: 6&ndash;9 kW</p></li><li><p>1,500 sq ft: 7&ndash;10 kW</p></li><li><p>2,000 sq ft: 10&ndash;14kW</p></li><li><p>2,500 sq ft: 12&ndash;16kW</p></li><li><p>3,000 sq ft: 16&ndash;20kW+</p></li></ul><p>Unfortunately, home square footage isn&rsquo;t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you&rsquo;d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.</p></div>
