History of National Energy Geek Day

Energy geeks strive to improve the homeowner’s experience by assisting them in saving money and lowering utility bills. The homes are also safer and more comfortable. However, because their work is often completed before the homeowner moves in, the profession is overlooked. Many people enjoy the benefits but do not know who made them possible. That is why we should celebrate the passionate, intelligent energy geeks who contribute to making the American dream of homeownership more attainable. Their expertise enables them to design and construct homes that strike the right balance of high performance, quality, efficiency, and comfort.

EnergyLogic, Inc., an applied building science experts company, founded National Energy Efficiency Day in 2018. It perfectly complements National Energy Geek Day because energy efficiency is at the heart of all energy geeks. On this day, we honor the men and women who work hard to make homes more energy-efficient, healthy, and resilient. From energy raters to existing home auditors, these professionals are dedicated to providing homeowners with better, safer living spaces.

It is not a simple job; it frequently requires driving long distances, working in all weather conditions, and developing relationships with everyone on the job site, from tradespeople and site supervisors to homeowners. For energy geeks, energy conservation is a way of life. The term ‘energy geek’ is a compliment rather than an insult. They talk about building science, inspecting the construction and appliances whenever they enter a new building — they live and breathe construction science. Their vision is for a world in which everyone lives in homes that are efficient, healthy, and resilient.

What is the average energy consumption of a U.S. home?

According to the U.S. Energy Information Administration, the average U.S. residential customer consumed approximately 887 kilowatt-hours (kWh) of electricity per month in 2023. Energy geeks work to bring this number down.

How many people work in the U.S. energy efficiency sector?

The U.S. energy efficiency sector is a significant employer, with over 2.2 million Americans working in fields like efficient lighting, HVAC, and building materials. This workforce is crucial for driving sustainable development.

What is the difference between energy efficiency and energy conservation?

Energy efficiency refers to using less energy to perform the same task, like an LED bulb providing the same light with less electricity. Energy conservation, on the other hand, is about reducing energy consumption by changing habits, such as turning off lights when leaving a room.

National Energy Geek Day Activities

  1. Design your own energy-efficient home

    Energy-efficient homes have taken the world by storm and can now be found everywhere from the United States to South Africa and beyond. Architects and construction experts have embraced this new way of home construction, so why shouldn’t you? National Energy Geek Day is your chance to design your own energy-efficient home to showcase your inner energy geek.

  2. Read the biography of a famous green architect

    A few iconic, well-respected, and visionary green architects have created beautiful and unique homes around the globe. You can read about Frank Lloyd Wright, Peter Busby, and Norman Foster to learn more about what it takes to not only be a visionary but also to create a green home.

  3. Build a green model of your home

    This one is for the whole family. Find some eco-friendly craft materials and create a floor plan for your home. After that, start cutting out the walls and constructing the roof so you can create your own little model of your home using green materials. Keep it as a decoration or put it in your study to keep you motivated.

5 Ways You Can Be Sustainable

  1. Give your clothes a cold wash

    If your clothes are not filthy, wash them in cold water first before drying them, as heating water consumes a lot of energy.

  2. Switch to L.E.D.

    Buy a set of L.E.D. light bulbs to replace any old incandescent bulbs as they burn out; they are about six times more efficient and last much longer.

  3. Solar power saves money

    In areas where electricity is more expensive, solar power becomes a better bargain, and some states or communities offer tax breaks and other financial incentives to sweeten the deal even more.

  4. Hang your laundry outside

    Electric dryers consume 5% of the average household's electricity consumption, so hanging your laundry on an outdoor clothesline or indoor drying rack saves energy and money while lowering your carbon footprint.

  5. Get reusable cloths and napkins

    It is far less expensive to wash and reuse a set of cloth napkins or dish towels than to go through roll after roll of paper towels every month.
