Another great idea of where to place solar panels. Using them to create shade is "stacking functions" - a key strategy in permaculture design. Where you place things can either be wasteful or highly efficient, especially if it can then perform more than one service.

California is exploring placing solar panels where they can help save water, crops, and reduce urban heat islands. Increases health benefits, $$ savings, resource preservation. There is nothing more effective than whole systems design to solve multiple problems. www.thecooldown.com/green-tech/p...

California's first-of-its-kind solar project could save 63 billion gallons of water annually
California's canal-top solar pilot has wrapped up, and the early results suggest the idea could do much more than generate clean electricity.

Systems thinking is a necessity if we want to use the energy we produce most efficiently and cost effectively. Why don't we do this already? It's a travesty, really. There is no excuse for the neglect of well-designed distributed energy networks.

A really excellent reason to transition to regenerative agriculture/agroecology. Much more resilient! It will take effort, creativity, and work but the outcomes are so much better than not doing it. Worth it on every level! All indicators point to backing away from fossil fuels.

This trend will only continue -renewable energy gets cheaper, fossil fuels gets more expensive. The technology continues to improve and there is a lot more upside potential to it. Combine with walkable neighborhoods/cities for maximum quality of life improvements.

While I haven't read the study, burning wood should not be considered a "renewable" energy, imo. The only way it should be burned is gasification/biochar production with biochar used to capture carbon long term. Even then, the design needs to be net benefit on multiple fronts, including ecosystems.
Burning wood for power worse for climate than gas equivalent, report finds.

Imagine your community owning its own source of electricity. There are various ways this works but the commonality is that it gives renters and people who can't install panels on their homes access to local renewable energy and cuts costs.

Koreen Brennan @koreen.bsky.social · 17/04/2026
This is a trend that should be legalized in every state and country. Balcony solar allows renters and others who could otherwise not benefit from reduced utility bills to tap into the power of solar. Is it legal in your region? www.thecooldown.com/green-home/v...

When you really look at what's going on in some agroforestry systems, it's astonishing how well designed they are. Some oases are many hundreds of year old, producing food that entire time with minimal care. Work with nature, not against her.

Just to balance out the idea of solar panels on parking lots... The times I've lived in bikeable/walkable neighborhoods are some of the most pleasurable memories of my life. Can't say enough about that lifestyle. Would much rather be able to safely bike than drive and park.

In Central America, fast growing high protein trees like Gliricidea are used for living fence posts, and trimmed (pollarded) yearly to feed animals enclosed by the fences. Fence posts are created by sticking branches in the ground that root. Fodder trees can also create shelter belts, hedges, etc.

Droughts create hydrophobic soil; soil that rejects water. It takes a fair amount of rain before soil will accept water as on the left. This means the drought continues *and* flash floods can occur. This video provides graphic evidence. www.youtube.com/watch?v=urQH...

A good chunk of the country is experiencing extreme drought. If we keep developing technology, etc, with no viable (i.e. multisolving/systems thinking) resource plan, it is guaranteed to bite us in the butt. It already is, with higher prices and looming water shortages in some areas.
