Recently shuttered coal mines around the world can have new life as solar farms, potentially adding nearly 300 gigawatts (GW) of clean energy by 2030, a first-of-its-kind analysis by researchers from Global Energy Monitor (GEM) has found.

GEM’s Bright side of the mine report identified 312 surface coal mines that had been closed since 2020, as well as 134 that were likely to close by 2030. Together, these wastelands cover 2,250 square miles, reported The Guardian.

“Coal was once billed as the ‘buried sunshine’ of a prehistoric past. But the world has now entered an age of solar energy — a time when harnessing the sun has become more accessible, affordable, and environmentally sustainable than digging it up in fossil fuels,” a press release from GEM said.

Our new analysis finds that converting 446 coal mines could add nearly 300 GW of solar — equal to 15% of global capacity.

Most of this potential is concentrated in a few regions, highlighting where targeted action could deliver outsized clean energy gains.

The world installed a record nearly 600 GW of solar capacity last year, and over 2,000 GW of utility-scale solar projects are currently in development. But these projects require widespread land use, and developers often find it hard to find prime locations that are not off limits or already being used. But there are vast tracts of scarred land across the globe in the form of abandoned coal mines that can be repurposed.

Since 2020, GEM has conducted a global survey of shut-down surface coal mines and those with planned closures by the end of the decade. The first-time analysis showed that more than 300 of these mines could house roughly 103 GW of photovoltaic (PV) solar capacity, while large operations that are scheduled to close could host another 185 GW across 127 sites.

Because they are already cleared and grid-adjacent, these abandoned mines are prime locations for renewables.

“If these potential solar projects came to fruition, the world could build almost 300 GW of solar capacity on mined out lands by the end of 2030. Uptake on that scale is equal to 15% of the solar that has already been built globally and would add enough solar capacity to inch the world one step closer to tripling renewables before the end of the decade,” GEM said.

Some of the transitional projects have already begun. New data from GEM on coal-to-solar projects shows that there are 90 operational conversions with 14 GW of capacity in China, and 46 additional projects with nine GW of capacity currently in the planning stages.

“The coal-to-solar transition offers a rare chance to repair the environmental hazards and eyesores of open pits,” GEM said. “Constructing solar on upheaved lands isn’t just land reclamation — it’s a chance to align land restoration, clean energy goals, and local job creation.”

Strip mining has turned former wildlife habitats into polluted wastelands stripped of their topsoil. But if the sites were converted to house solar energy plants, they would be able to help the planet by generating enough renewable energy to power a country the size of Germany, the report said.

“The legacy of coal is written into the land, but that legacy does not have to define the future. The coalmine to solar transition is underway, and this potential is ready to be unlocked in major coal producers like Australia, the U.S., Indonesia and India,” said Cheng Cheng Wu, project manager for GEM’s energy transition tracker, as The Guardian reported. “Repurposing mines for solar development offers a rare chance to bring together land restoration, local job creation, and clean energy deployment in a single strategy. With the right choices, the same ground that powered the industrial era can help power the climate solutions we now urgently need.”

Outdoor Projects You Can DIY for Almost Nothing

Published

on

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

Published

on


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.

Nadina Galle, an ecological engineer and author of The Nature of Our Cities, is our guest on .

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.
