The Full Story

Electricity is essential in modern life because it powers nearly everything we rely on daily. Here are some key reasons why we need electricity:

1. Everyday Convenience

• Lighting: Provides visibility at night and in dark spaces.

• Appliances: Powers refrigerators, microwaves, washing machines, and more.

• Communication: Runs phones, computers, and the internet for work, socializing, and information access.

2. Safety & Security

• Home Security: Powers alarm systems, surveillance cameras, and motion sensors.

• Medical Equipment: Vital for hospitals and home medical devices like oxygen machines and pacemakers.

​

3. Comfort & Climate Control

• Heating & Cooling: Powers HVAC systems, space heaters, and air conditioners.

• Hot Water: Essential for water heaters in homes and businesses.

• Entertainment & Leisure: Powers TVs, gaming consoles, and streaming devices.

​

Installing a home generator is a great way to ensure backup power during outages. Here’s what you need to know before getting started:

1. Determine Your Power Needs

• Essential Loads vs. Whole-House Power: Decide if you want to power only essentials (e.g., fridge, heating, lighting) or your entire home.

• Wattage Calculation: Add up the wattage of the appliances you want to run. A small generator (3,000-5,000W) can handle basics, while whole-house systems need 10,000W+.

• Starting vs. Running Watts: Some appliances (like A/C units) require extra power to start up.

2. Choose the Right Type of Generator

• Portable Generators: Less expensive, runs on gasoline or propane, must be manually started and connected.

• Standby Generators: Permanently installed, automatically turns on during power loss, typically runs on natural gas or propane.

• Inverter Generators: Quieter and more fuel-efficient, good for sensitive electronics.

3. Fuel Source Options

• Gasoline: Readily available but has a short shelf life and requires refilling.

• Propane: Burns cleaner and stores longer, but tanks may need frequent refilling.

• Natural Gas: Continuous fuel supply if you have a connection.

• Diesel: More fuel-efficient, but generators are larger and pricier.

4. Installation Considerations

• Location: Place it outside, at least 5 feet away from windows and doors for ventilation.

• Transfer Switch: A must-have for safely connecting a generator to your home's electrical panel.

• Professional Installation: Standby generators require a licensed electrician to install and connect to your electrical system.

5. Budgeting

• Portable Generators: $500 - $2,500

• Standby Generators: $3,000 - $10,000+ (including installation)

• Transfer Switch & Installation: $500 - $3,000

• Fuel Costs: Varies based on type and availability.

6. Maintenance & Safety

• Routine Maintenance: Regular oil changes, spark plug replacements, and fuel checks.

• Carbon Monoxide Safety: Always run the generator outdoors and use CO detectors.

• Load Management: Don’t overload the generator—manage power use efficiently.

7. Local Codes & Permits

• Permits: Some areas require permits for installation, especially for standby generators.

• Noise Restrictions: Check local ordinances for noise limits.

• Utility Company Notification: If connecting to your home’s system, your power company may require notification.

How to Size a Home Generator

Sizing a generator correctly ensures you have enough power to run essential appliances—or your entire home—during an outage. Follow these steps to determine the right size for your needs.

1. Determine Your Power Needs

Decide whether you want to:

• Power essential appliances only (e.g., fridge, lights, furnace, well pump).

• Power major appliances and HVAC (e.g., central A/C, water heater).

• Power your entire home (every circuit, just like utility power).

2. List Essential Appliances & Devices

Write down the wattage requirements for each item you want to power. You can check the appliance label, owner's manual, or use estimates:

Appliance Running Watts Starting Watts (if applicable)

Refrigerator/Freezer600W1,200W

Furnace (Gas)800W1,600W

Well Pump (1/2 HP)1,000W2,000W

Window A/C (10,000 BTU)1,200W1,800W

Central A/C (3-Ton)3,500W6,000W

Electric Water Heater4,500W4,500W

Lights (LEDs)300WN/A

TV & Internet300WN/A

Microwave1,000W1,500W

Electric Stove (1 burner)1,500W2,000W

Washing Machine1,200W2,300W

• Running Watts: Continuous power required while in use.

• Starting Watts: Extra power needed for the first few seconds when turning on (important for motors and compressors).

3. Calculate Total Power Requirements

• Step 1: Add up the running watts of all the appliances you want to run.

• Step 2: Identify the highest starting wattage needed.

• Step 3: Add this highest starting wattage to your total running watts.

Example Calculation (Essentials + HVAC):

• Running Watts: 8,900W

• Highest Starting Wattage (Central A/C): 6,000W

• Total Required Generator Size = 8,900W + 6,000W = 14,900W (or 15 kW)

4. Choose the Right Generator Size

Use your total wattage to select a generator:

Generator Size Power Capacity Best For

5,000-7,500WEssentials (fridge, lights, small appliances)Small homes or temporary power

8,000-12,000W (8-12 kW)Most household essentials + some heating/cooling Medium-sized homes

13,000-20,000W (13-20 kW)Whole-home power, including HVAC Large homes, complete backup

22,000W+ (22+ kW)Whole-home with heavy loads Large homes with multiple A/C units

5. Consider Fuel Type & Efficiency

• Gasoline: Common for portable generators but requires refueling.

• Propane: Cleaner, longer shelf life, but lower energy output.

• Natural Gas: Ideal for standby generators, unlimited fuel source.

• Diesel: More efficient but requires larger, commercial-grade generators.

​

If you’re looking for alternative ways to power your home beyond a generator, there are several options available. These alternatives can provide backup power during outages, reduce reliance on the grid, or even allow for complete energy independence.

1. Solar Power (Photovoltaic Panels)

✅ How It Works: Solar panels capture sunlight and convert it into electricity.
✅ Pros:

• Renewable & sustainable energy source.

• Low maintenance with a lifespan of 25+ years.

• Can be paired with battery storage for backup power.
  ✅ Cons:

• High initial installation cost.

• Dependent on sunlight availability (less effective in cloudy areas or at night).

• Requires space for panels (roof or ground-mounted).

🔹 Best Option For: Reducing electricity bills and gaining energy independence.

2. Wind Power (Home Wind Turbines)

✅ How It Works: Wind turbines generate electricity from wind movement.
✅ Pros:

• Can produce power day and night if wind conditions are right.

• Works well in rural or open areas with strong wind speeds.

• Pairs well with solar for continuous power generation.
  ✅ Cons:

• Requires consistent wind speeds (at least 12-15 mph).

• Installation can be expensive and requires space.

• Local zoning laws may restrict turbine installation.

🔹 Best Option For: Rural homes with open land and steady wind conditions.

3. Battery Storage Systems

✅ How It Works: Batteries (like Tesla Powerwall, Generac PWRcell, or DIY battery banks) store excess energy from solar, wind, or the grid to use later.
✅ Pros:

• Provides backup power during outages.

• Can store solar or wind energy for nighttime or peak usage.

• Reduces reliance on the grid.
  ✅ Cons:

• Expensive upfront cost.

• Limited capacity (may not power the whole home for extended periods).

• Needs a charging source (solar, wind, or grid).

🔹 Best Option For: Homes with solar panels or those seeking short-term backup power.

​

4. Grid-Tied with Net Metering

✅ How It Works: Remain connected to the utility grid but generate your own power (solar, wind, etc.), selling excess energy back to the utility.
✅ Pros:

• Reduces electricity bills by offsetting usage.

• No need for expensive battery storage.

• Still has power access when renewable sources aren’t producing.
  ✅ Cons:

• Requires cooperation from the utility company.

• May not work during power outages unless combined with battery storage.

• Some areas don’t offer net metering programs.

🔹 Best Option For: Homeowners wanting lower energy bills while staying connected to the grid.

Which Alternative is Best for You?

• For Backup Power: Battery storage, fuel cells, or a generator.

• For Sustainable Living: Solar, wind, or hydro.

• For Off-Grid Living: A combination of solar, wind, batteries, and possibly a backup generator.
