Realtors are used to answering questions about available closet space and the number of bathrooms, but there’s a new question people are asking when searching for a new home:
How’s the energy efficiency?
Recent research has shown that more Americans are searching to buy or build an energy-efficient home. And with climate change worsening and energy bills rising, it’s perhaps not much of a surprise that sustainability is shifting to a top priority.
But just how much of a difference does it make? Do homes that help people to conserve energy really help to save money and the planet?
Let’s look at some of the top statistics for energy-efficient homes.

Energy-Efficient Homes: Statistics and Facts
A survey from the National Association of Realtors (NAR) revealed that 63% of agents and brokers find it valuable to promote energy efficiency in a house listing.
Here are some stats that back up why homeowners are — or why they should be — prioritizing energy-savvy homes.
- Energy-efficient-rated homes sell for 2.7% more than unrated homes, and better-rated homes sell for 3% to 5% more than lesser-rated homes.
- Nine out of 10 homebuyers would rather buy a more expensive home with energy-efficient features versus a cheaper and less energy-efficient home.
- Real estate agents report that energy efficiency adds $8,246 to a home’s value in 2022, up more than $1600 from 2021.
- Homes and commercial buildings consume 40% of the energy used in the United States.
- To enhance energy efficiency, homes can benefit from upgrades such as air leak sealing, new windows, programmable thermostats, insulation, energy-efficient water heaters, Energy Star appliances, solar panels, and LED lighting.
- Compared to traditional homes, LEED-certified homes typically consume 20% to 30% less energy, with some achieving remarkable energy reductions of up to 60%.
- Residential energy accounts for roughly 20% of annual greenhouse gas (GHG) emissions in the U.S.
- A properly insulated attic can reduce your energy bill by 10% to 50%, according to the Department of Energy.
- Switching to energy-efficient windows can save the average homeowner up to $583 per year.
- Inefficient windows lead to $50 billion in energy waste per year in the U.S.

Energy-Efficient LED Lights for Homes: Statistics and Facts
- LED bulbs use about 90% less energy and last 25 times longer than incandescent bulbs, saving the average household about $225 per year.
- An average household dedicates 15% of its energy budget to lighting. Using new technologies can reduce lighting energy use in your home by 50% to 75%.
- LED lights contain no mercury and are 95% recyclable.
- LEDs excel in energy efficiency, converting 95% of their energy into light, while incandescent bulbs waste a staggering 90% of their energy as heat.
- By 2030, LEDs are projected to account for an impressive 87% of all lighting sources worldwide.
- The widespread adoption of energy-efficient LED lighting is projected to slash global electricity consumption for lighting by 30-40% by 2030.
Energy-Efficient Roofs for Homes: Statistics and Facts
Replacing your roof will not only help protect your home from the elements, but it can also drastically increase its energy efficiency. And as it turns out, the best roofing materials for the environment are also the best roofs for lowering personal energy consumption.
- You can save up to 30% on air cooling costs by installing a metal roof over an asphalt one.
- A green roof would save about $200,000 over its estimated lifespan of 40 years, with nearly two-thirds of that coming from reduced energy costs.
- Metal roofs are 100% recyclable after use. Additionally, aluminum roofing materials are made from 95% post-consumer recycled contents and steel roofing is made from 10% post-consumer recycled contents.
- A metal roof replacement will increase your home value by more than $23,000 — more than $6,000 more compared to an asphalt shingle roof replacement.

Energy-Efficient Home HVAC Systems: Statistics and Facts
Heating, ventilation and air conditioning (HVAC) systems are responsible for a whopping 48% of a home’s energy usage. Small changes like switching from a gas furnace to a heat pump or choosing an air conditioner with a better SEER rating can make a big difference for your home and for the planet.
- Conventional air conditioner systems cost over $29 billion annually, according to the U.S. Department of Energy.
- The $4.28 billion High-Efficiency Electric Home Rebate Program (part of the Inflation Reduction Act) provides rebates of up to $8,000 to install heat pumps, which can both heat and cool homes. It also provides a rebate of up to $1,750 for heat-pump water heaters.
- Standard water heaters account for 14-18% of your utility bill.
- Energy Star-certified smart thermostats can save homeowners between 8% and 15% on electricity costs.
- According to The U.S. Department of Energy, adjusting your thermostat by 7-10 degrees for eight hours a day can save up to 10% on energy costs.
Energy-Efficient Home Solar Systems: Statistics and Facts
By installing solar panels on your roof or switching to solar shingles, you can rely less on traditional energy sources and generate your own electricity. Plus, housing trends point toward an increasing amount of interest in homes with solar features.
- On average, a U.S. homeowner sees $20,000 of lifetime savings from switching to solar energy.
- Solar installations increase a home’s resale value by an average of 4.1%.
- The cost of adding solar panels has dropped more than 70% over the last decade.
- The number of U.S. homes with installed solar panels has increased by an average of 32% per year since the year 2005.

Energy Conservation: Statistics and Facts
- Americans waste $200 to $400 in home energy expenses per year due to air leaks and outdated HVAC (heating, ventilation and air conditioning) systems.
- Energy efficiency measures, including building insulation and efficient appliances, are projected to save IEA countries USD 680 billion in energy costs in 2022, representing a 15% reduction in their total energy expenditure.
- Making energy-efficient choices helps burn fewer fossil fuels, which helps lessen the bi-product of greenhouse gasses and other air pollutants.

Outdoor Projects You Can DIY for Almost Nothing
It always strikes us as amusing how many DIY projects you see online that seem to require more time and more money than it would take to simply buy the thing they’re trying to DIY in the first place. Are we missing the point?
We think that doing things ourselves and taking back the power to create instead of simply consuming is absolutely vital to the green movement. But if you don’t already have the materials and spend a lot of money purchasing craft supplies, does it really make sense to DIY?
These eight projects are true do-it-yourself masterpieces. One-of-a-kind outdoor projects you can make for almost nothing, with supplies you most likely already have or can easily pick up second hand for a song. Roll up your sleeves and let’s get started!
1. Teapot/Teacup Bird Feeder

Do you have one of Grandma’s old tea sets lying around that doesn’t quite fit into the sleek modern aesthetic you’ve been cultivating? Put it to great use by feeding the birds in your area — in style.
Thrift stores are always awash in old china, so if you don’t already have the old tea set, consider going wild and spending a few bucks for this DIY delight. You’ll find blogger Dinah Wulf’s instructions for the teacup bird feeder at DIY Inspired.
Safety note: Use sturdy twine or cord — not chain — to hang the feeder. Birds can catch their toes in chain links, which causes serious injury. The National Audubon Society also recommends cleaning seed feeders every two weeks (more often in hot, humid weather) by scrubbing with soap and water and soaking in a 50-50 vinegar-water solution to prevent the spread of avian disease.
2. Gardening Tool Storage

What on earth do you do with those rusty-as-heck, old-school garden rakes hanging around your garage? Well, if you’re any sort of DIY genius, you press them into service as a gardening tool holder.
The original inspiration for this project came from Beth Logan at Artstuff Ltd., whose blog has since gone offline. For a current walkthrough, see the Repurposed Rake Tool Rack tutorial at DIY n Crafts (project #14 in their roundup of 25 ways to reuse old garden tools). The concept is embarrassingly simple — remove the rake handle, mount the head tines-out on a fence or garage wall, and use the tines themselves as hooks for trowels, gloves, and pruners — but eye-catching enough to make you look like a DIY pro.
3. Bottle Tree

Do you like wine? No, I mean do you really like wine? Do you want a reason to drink more of it? And does your garden need a cute border? This sustainable, upcycled garden border may be just the project for you. You might have to expand your drinking list to include bottles of various shapes, sizes, and colors — but variety is the spice of life.
When friends ask how you managed to collect so many bottles, just laugh gaily and then distract them with your dainty teacup bird feeder. The bottle tree tradition itself runs deep — Mississippi garden writer Felder Rushing traces the practice back through African American Southern folk art and, by his own research, as far as ancient Egypt and Mesopotamia. See his bottle tree gallery and history for inspiration, or jump straight to his how-to guide for building one out of a cedar snag, rebar, or just about anything else.
4. Colorful Outdoor “Tiles”

If your backyard isn’t perfectly landscaped and manicured, with an impeccably tiled “outdoor living space,” don’t despair. You can use up all those half-empty paint cans and create a Pinterest-worthy colorful backdrop for evenings spent clustered around a fire or barbecue.
Pop a few coats of paint on cement tiles and you have a one-of-a-kind flooring solution. If you rent, the same effect could be achieved on a more temporary basis by letting the kids go wild with sidewalk chalk and create a mosaic masterpiece. Check out Elsie’s Painted Patio Tiles at A Beautiful Mess for the back story on this DIY idea. (Heads up: the original author noted she had to touch up the paint each spring in Missouri winters — a porch and patio floor enamel will hold up better than wall paint.)
5. Home Sweet Gnome

Okay, this one might be the least practical idea of the bunch, but that may be why I love it oh so much. If you have a stump in your backyard and you’re not willing or able to pay the truly insane amount it costs to have it ground down and removed, how about making it into a little gnome home? This is the perfect outdoor project if you have small children in your life.
Construct the trappings of a little house — door, windows, winding garden path — from found objects or natural materials, and affix them to the stump. Bonus points if you don’t tell the kids about this particular DIY project and allow them to simply stumble upon it one day in the garden. My mind would have been blown if I had come across one of these as a seven-year-old. For a step-by-step build, see this Gnome Tree Stump Home tutorial on Instructables.
Safety note: Don’t use an angle grinder to gouge windows or doors into a stump. Use a chisel and mallet for shallow detail work, or attach decorative pieces (driftwood, bark, polymer clay) to the outside instead.
6. Mosaic Stepping Stones from Broken China

Every household eventually accumulates a small graveyard of chipped mugs, a single survivor from a four-piece dinner set, or a beloved teapot with a hairline crack. Rather than tossing them — broken ceramics generally aren’t accepted in curbside recycling — embed them in concrete stepping stones for a garden path that’s genuinely one of a kind.
This pairs beautifully with the teacup project above: any teacups that don’t make it past Project #1 (you will break a few) can come back as paving. The DIY mosaic stepping stones tutorial at Gardening.org walks through the full process — breaking ceramics safely inside a drop cloth, sizing pieces to half-inch to one-inch fragments, pressing them into wet concrete, and sealing the surface so sharp edges don’t cause injury underfoot. Basic mold options include an old cake pan, a plastic plant saucer, or a purpose-built stepping stone form from a craft store.
Safety note: Wear safety glasses and heavy gloves when breaking ceramics. Once cured, run a finger over the surface to check for protruding edges and file or sand any down before placing the stone where bare feet might land.
7. Vertical Pallet Herb Garden
Shipping pallets are one of the world’s most abundant near-free materials. Small businesses, garden centers, and feed stores often have stacks of them out back, and asking politely beats the alternative of seeing them landfilled. Mounted vertically against a sunny wall or fence, a pallet becomes a stacked planter that holds enough herbs to keep a kitchen in basil, thyme, parsley, and chives all season.
Grit Magazine published a clear how-to for a vertical pallet planter — line the back and sides with landscape fabric or heavy plastic to hold soil, fill through the slats, and plant each gap as its own row. The gaps act as natural divisions, so different herbs don’t fight for the same root space.
Safety note: Use only heat-treated pallets for anything edible. Look for the IPPC stamp with the letters HT (heat treated) and avoid any stamped MB (methyl bromide — a fumigant restricted under the Montreal Protocol). Unstamped pallets are unknowns; skip them for food crops. The same heat-treated pallets are fine for ornamental flowers either way.
8. Punched Tin Can Lanterns
Steel food cans — soup, tomato, coffee — are one of the most recyclable materials on Earth, but the recycling-then-buying-something-decorative loop has plenty of slack in it. With nothing more than a hammer, a few nails of varying sizes, and the freezer, an empty can becomes an outdoor lantern that throws constellation patterns across a patio at dusk.
HGTV’s tin can lantern tutorial covers the trick that makes this project work: fill the can with water and freeze it solid before punching, so the ice supports the can wall and prevents denting. Sketch your pattern on paper, tape it to the frozen can, punch through with a nail at each marked dot, and let the ice thaw. Drop in a battery tealight (much safer outdoors than a real flame) and group them along a walkway or down the center of an outdoor table.
The Point of All This
None of these projects requires you to buy more than a tube of waterproof adhesive, a bag of concrete, or maybe a stepping stone mold. The materials — chipped china, leftover wine bottles, empty cans, a forgotten pallet, an old rake — are already in your house or someone else’s. That’s the point. The greenest project is the one that uses what already exists, and the best part is that yours will look like nobody else’s.

Best of Sustainability In Your Ear: Author Nadina Galle on The Nature of Our Cities
More than half the world’s population—4.4 billion people—live in cities today. That number is expected to rise to 80% by 2050. Our guest, Nadina Galle, is a trailblazing ecological engineer and author of The Nature of Our Cities. She is an ecological engineer who studies the intersection of nature and technology in urban environments. Nadina developed the concept of an Internet of Nature (IoN) that uses tools like artificial intelligence, automation, and sensors to support and enhance ecosystems within cities. Nadina’s book offers a transformative perspective on how urban spaces can be reimagined in the face of climate change and sprawling development. She shares the inspiring story of the Groene Loper project in Maastricht, Netherlands, where soil sensors were deployed to monitor tree health. The results were remarkable, with trees supported by this technology growing up to three times larger than those without it. This is a powerful example of how technology can not only protect trees but also transform urban spaces into healthier, greener environments.

From fire and the wheel to the reinforced concrete frames that define modern buildings, we are surrounded by technology. We tend to forget that technology emerged in response to nature — too often, we treated nature as the enemy, the chaos to be contained instead of recognizing that nature’s cycles and changes are the harmony we need to join to sustain society. The loss of any semblance of natural patterns, which ultimately leads to the depletion of the resources necessary for life, has inevitably led to the collapse of previous major civilizations. Modern society has more runway than previous societies because we have created a global economy, but that risks an even greater fall for our species when the ecological underpinnings of our prosperity collapse. The Nature of Our Cities, is a powerful, straightforward, and emotionally resonant book to help you think through your role and choices in the restoration of nature. You can find it on Amazon or Powell’s Books.
