[{"content":"Home energy planning usually goes wrong when the shopping starts before the load list.\nA portable power station, home battery, EV charger, solar array, heat pump, or induction range can all be the right upgrade. They can also be expensive distractions if they solve the wrong problem. The first step is not a product. It is a short map of what your home needs to run.\nThe 30-minute first pass Write down five groups:\nCritical loads: refrigerator, modem, phone charging, medical devices, sump pump, heat needed for safety Comfort loads: lights, fans, microwave, small appliances, TV, work setup Large electric loads: heat pump, water heater, dryer, range, EV charger Outage duration: a few hours, overnight, one day, or several days Upgrade intent: resilience, lower energy use, electrification, comfort, or all of them That list is enough to stop most bad buying decisions.\nt TipStart with measurement If you do not know what a device uses, measure it or estimate conservatively. A plug-in power meter (paid link) is often more useful than another comparison chart. Choose the first path If your main problem is\u0026hellip; Start with\u0026hellip; Short outages Outage Priority List Confusing numbers Watts, kWh, and Loads Backup shopping Backup Power Sizing Solar curiosity Solar Panel Sizing Heating and cooling Heat Pump Buying Guide Kitchen electrification Induction Cooktop Buying Guide The order that usually works First, reduce waste. Air sealing, insulation, efficient lighting, and better controls shrink the system you need. The Department of Energy makes the same point for renewables: efficiency comes before sizing a renewable system.\nSecond, plan resilience. Decide what must run during an outage before you compare backup devices.\nThird, electrify thoughtfully. Heat pumps, induction cooking, and EV charging can be excellent upgrades, but they may require panel capacity, new circuits, load management, or professional work.\nFourth, maintain what you install. Filters, firmware, battery state of charge, panel cleaning, and test runs matter more than the brochure suggests.\nFor smaller homes and off-grid thinking, read Tiny Home Solar Power Sizing and Tiny Home Heating and Cooling . Tiny homes make the same load math visible faster.\nYour next move Make a one-page home energy note with:\nthe loads you care about the outage duration you want the upgrades you are considering the electrical work that may need a pro the questions you need answered before buying Then use the rest of this library to fill in the numbers.\n","contentType":"home-energy-lab","date":"2026-05-04","permalink":"/home-energy-lab/guidebooks/quickstart/","section":"home-energy-lab","site":"Fondsites","tags":["quickstart","beginner","home energy","backup power","electrification"],"title":"Home Energy Quickstart: Make the Load List Before You Buy"},{"content":"An energy audit is not a scolding session. It is a way to find the upgrades that make every later energy decision smaller.\nBefore solar, batteries, or a heat pump, you want to know where your home leaks energy, which loads are unusually large, and which comfort problems are really insulation, air sealing, duct, or control problems.\nThe three-layer audit 1. Bills and patterns Collect a year of utility bills if you can. Look for seasonal peaks. Winter peaks often point to heating, hot water, or resistance heat. Summer peaks often point to air conditioning, dehumidification, pool pumps, or poor shading.\n2. Plug loads Measure or estimate the devices that run often: office equipment, entertainment systems, refrigerators, freezers, dehumidifiers, aquariums, networking gear, and battery chargers.\nFor home-office loads, Mechanical Keyboard Guide is not an energy site, but its desk-first audience is a useful reminder: small always-on desk gear adds up when it never turns off.\n3. Building shell Walk the home like a detective:\ndrafty doors and windows attic insulation gaps unsealed penetrations hot or cold rooms duct leaks or crushed ducts damp areas and condensation If moisture is part of the problem, Tiny Home Ventilation and Moisture Control is relevant even in larger homes because the sequence is the same: measure, ventilate, dehumidify, then fix the cold or wet surface.\nAffiliate-friendly audit kit You do not need a professional toolbox to start. Useful search categories:\nplug-in electricity usage monitor (paid link) indoor humidity monitor (paid link) door weather stripping (paid link) smart power strip (paid link) Do not buy everything at once. Buy the tool that answers the next question.\nWhen to hire a professional Hire help when the audit affects combustion safety, electrical panels, ducts inside difficult spaces, insulation in risky areas, or any issue where local code and permits matter. A blower-door test, infrared inspection, or HVAC assessment can be worth it when comfort problems are persistent.\nWhat to do with the findings Sort improvements into three buckets:\nNo-regret: LEDs, weather stripping, filter changes, power strip habits Plan carefully: heat pump, water heater, solar, batteries, EV charging Professional scope: panel work, dedicated circuits, duct changes, major insulation The win is not a perfect audit.

Short high-power loads and long low-power loads both matter.\nContinuous, intermittent, and surge loads Continuous loads These run for long stretches: routers, medical equipment, aquarium gear, some fans, and standby electronics.\nIntermittent loads These cycle: refrigerators, freezers, sump pumps, dehumidifiers, and heat pumps.\nSurge loads These draw extra power at startup: pumps, compressors, motors, some power tools, and some appliances. Surge affects inverter sizing even when total energy use looks reasonable.\nHow to measure Use device labels, manuals, smart plugs, a plug-in power meter (paid link) , utility data, or a whole-home monitor.
