    { "@type": "Question", "name": "Why did my electric bill double this month?", "acceptedAnswer": { "@type": "Answer", "text": "A doubled bill usually means the home used more kilowatt-hours, the effective price per kilowatt-hour increased, or both. Compare kWh, billing days, and rate changes before investigating major household loads." } },
    { "@type": "Question", "name": "Why is my electricity bill high when nobody is home?", "acceptedAnswer": { "@type": "Answer", "text": "An empty home still powers heating and cooling, water heating, refrigeration, pumps, security equipment, network gear, and standby devices. Hourly utility data can reveal the base load." } },
    { "@type": "Question", "name": "How much does a space heater cost to run per day?", "acceptedAnswer": { "@type": "Answer", "text": "A 1,500-watt heater uses 1.5 kWh per full heating hour. At $0.17 per kWh, eight hours costs approximately $2.04." } },
    { "@type": "Question", "name": "How much electricity does an old freezer use?", "acceptedAnswer": { "@type": "Answer", "text": "Measure it over at least 24 to 72 hours. Multiply daily kWh by 365 and by the electricity rate to estimate annual cost." } },
    { "@type": "Question", "name": "What appliances use electricity when turned off?", "acceptedAnswer": { "@type": "Answer", "text": "Devices with displays, remote controls, network connections, chargers, or instant-on features can use standby power." } },
    { "@type": "Question", "name": "Why is my electricity usage high at night?", "acceptedAnswer": { "@type": "Answer", "text": "Common nighttime loads include HVAC, water heating, EV charging, refrigeration, pumps, dehumidifiers, and scheduled appliances." } },
    { "@type": "Question", "name": "How many watts are needed to run a refrigerator?", "acceptedAnswer": { "@type": "Answer", "text": "Many refrigerators draw roughly 100 to 250 watts while running, but compressor starting surge can be several times higher. Verify the specific appliance." } },
    { "@type": "Question", "name": "How much fuel does a generator use per day?", "acceptedAnswer": { "@type": "Answer", "text": "Fuel use depends on generator size, fuel type, electrical load, efficiency, and runtime. Use the manufacturer's consumption data at a load close to yours." } },
    { "@type": "Question", "name": "What is the best backup power option without gasoline?", "acceptedAnswer": { "@type": "Answer", "text": "For selected plug-in essentials, a correctly sized portable battery is often the simplest gasoline-free option. Hardwired loads may require a professionally designed home battery system." } },
    { "@type": "Question", "name": "What emergency backup power is suitable for an apartment?", "acceptedAnswer": { "@type": "Answer", "text": "Prioritize rechargeable lights, power banks, a UPS, and a correctly sized portable battery. Never operate a fuel-burning generator or grill in an unsafe enclosed location." } },
    { "@type": "Question", "name": "How long can a battery run a refrigerator and freezer?", "acceptedAnswer": { "@type": "Answer", "text": "Estimated hours equal usable battery watt-hours multiplied by inverter efficiency, divided by the appliances' average watts." } },
    { "@type": "Question", "name": "How many kilowatt-hours of battery backup does my home need?", "acceptedAnswer": { "@type": "Answer", "text": "Add the watt-hours required by each essential load, divide by usable battery capacity and system efficiency, then add reserve and confirm surge power." } }
