How to Reduce Your Carbon Footprint By Switching to Alternative Energy Sources

Why Reduce Your Carbon Footprint?

The main reason to reduce your carbon footprint is to combat climate change. As greenhouse gas emissions from burning fossil fuels continue to rise, the planet gets warmer. This leads to melting glaciers, rising sea levels, more extreme weather events, and the destruction of ecosystems. By reducing your personal carbon emissions, you can help fight climate change and preserve the planet for future generations.

Some key benefits of reducing your carbon footprint include:

  • Slowing climate change – Every bit of reduced emissions helps combat climate change. If enough people lower their footprints, it can have a real collective impact.

  • Saving money – Many carbon reduction steps like weatherizing your home or buying an electric vehicle will save you money on utilities and gasoline in the long run.

  • Improving health – Walking, biking, and eating less meat carries multiple health benefits like reduced risk of heart disease, diabetes, and cancer.

  • Leading by example – When you make green choices, you inspire friends, family, and neighbors to take action as well.

How Your Home Energy Use Contributes to Your Carbon Footprint

The energy used to power, heat, and cool your home likely makes up a significant portion of your carbon footprint. Most electricity in the US is still generated by burning fossil fuels like coal and natural gas.

Here are some facts about household energy use and carbon emissions:

  • The average US household produces about 48,000 pounds of carbon dioxide per year from their home energy use.

  • The largest chunk (31%) comes from heating systems like natural gas furnaces.

  • The next biggest share (17%) comes from electricity used to power appliances, devices, and lighting.

  • Nearly three quarters of US homes are still heated by natural gas or fuel oil furnaces which dump CO2 into the atmosphere.

  • Coal generated 23% of US electricity in 2019 while natural gas provided 38%. Both release copious greenhouse gases when burned.

So curbing your home’s energy appetite and switching to green power sources can massively shrink your carbon footprint.

Ways to Reduce Your Home Energy Use

Here are some impactful steps you can take to cut your home’s energy use and carbon footprint:

1. Get an Energy Audit

  • Having an expert conduct an energy audit can identify where your home is wasting energy and guide efficiency upgrades.

  • They use tools like blower doors and thermal imaging cameras to find leaks, gaps, and areas lacking insulation.

  • Many utilities and state agencies offer discounted or free audits. Investment in upgrades often pays for itself over time.

2. Upgrade Insulation and Sealing

  • One of the most effective ways to cut home energy use is by upgrading insulation in areas like the attic, walls, and basement.

  • Likewise, caulking and sealing air leaks around doors, windows and openings reduces drafts and wasted heating/cooling energy.

  • The Department of Energy estimates properly insulating and sealing can reduce home energy bills by up to 20 percent.

3. Replace Old Appliances and Devices

  • Swapping out old refrigerators, washing machines, and dishwashers for new ENERGY STAR models can cut their electricity use by 25-50%.

  • Replacing outdated light bulbs with efficient LEDs uses up to 80% less energy and lasts years longer.

  • Smart thermostats, power strips, and timers help reduce energy waste from heating/cooling, electronics, and lights when not needed.

4. Install High Efficiency HVAC Systems

  • Heating and cooling account for over half of home energy bills.

  • Replacing an old furnace or boiler with a new high efficiency model can reduce heating costs by 30% or more.

  • Upgrading to an Energy Star air conditioner also cuts cooling energy use substantially.

  • Heat pumps provide both heating and air conditioning in one unit and are over twice as efficient as furnaces.

Switching to Green Energy Sources

In addition to curbing energy use, switching your home’s electricity and heating to renewable energy sources offers the biggest carbon reduction opportunity. Green energy options to consider include:

Solar Power

  • Solar panels on your roof convert sunlight into electricity to power your home.

  • With net metering, excess power is sent to the grid and your utility bill is offset.

  • Solar lease financing options mean little or no upfront cost, just monthly payments lower than your old utility bills.

Wind Power

  • Residential wind turbines harness kinetic energy from the wind to generate emissions-free electricity.

  • Modern turbines for homes have lower noise levels and less visual impact than old windmills.

  • Wind turbines provide a stable power source regardless of weather changes compared to solar.

Geothermal Heating/Cooling

  • Geothermal heat pumps use underground piping loops to transfer heat between the earth and your home.

  • This provides heating, cooling, and hot water by extracting natural subterranean energy.

  • Geothermal systems can cut heating and cooling energy use by up to 50%.


  • Wood pellets made from compressed sawdust provide a low-carbon heating fuel for stove and boiler systems.

  • More advanced biodiesel systems allow oil furnaces to burn renewable fuels like vegetable oil with low particulates.

  • Limitations include feedstock transportation emissions and higher air pollutants than other options.

Additional Steps to Shrink Your Footprint

Beyond home energy, other choices that reduce your carbon footprint include:

  • Cut airplane travel and drive electric or hybrid vehicles instead of gas guzzlers. Walk, bike, or use mass transit whenever possible.

  • Make green improvements like low-flow faucets, energy efficient appliances and windows, and LED light bulbs.

  • Reduce waste by reusing, recycling, and buying products with minimal packaging.

  • Eat less meat and food sourced from far away. Support local and organic farms.

  • Weatherize and insulate your home to avoid energy leaks, and lower your thermostat in winter / raise it in summer.

  • Use renewable energy certificates or credits to offset emissions you cannot otherwise avoid.

  • Support legislation and policies at the local and national level that promote renewable energy and climate action.


The actions you take to lower home energy use and adopt renewable sources provide one of the most impactful ways for an individual to combat climate change. Plus, the cost savings from efficiency upgrades means the switch to green energy will often pay for itself over time. By making smart, eco-friendly choices, you can reduce your carbon footprint while helping pave the way to a more sustainable future.
