In the desert outside Abu Dhabi, construction crews are breaking ground on a project that sounds almost like science fiction: a solar power plant that never sleeps. For decades, the flaw in renewables has been obvious to even their strongest advocates. The sun sets, the wind stills, and suddenly clean energy needs backup. Fossil fuels, with all their costs to health and climate, have filled the gap. But what if that gap could be closed — not with gas or coal, but with sunlight stored in vast batteries beneath the sand? That is the wager the United Arab Emirates is…

TORONTO—Sent on behalf of the One Canadian Clean Economy Task Force, for which Clean Energy Canada serves as secretariat:As Canada navigates both economic headwinds and global opportunities—from rapidly shifting trade relationships to projects of national significance—a new task force composed of clean economy industry associations and organizations has officially launched today, with an action plan for governments scheduled to release later this fall. The One Canadian Clean Economy Task Force is made up of members representing companies across critical minerals, batteries, clean transportation, clean buildings, forest products, clean electricity, and clean technology.  As its name suggests, the task force’s forthcoming recommendations will…

We’ve all been there: standing in the middle of a store, clutching a flashy, expensive gift, and agonizing over whether to blow our monthly budget or play it safe. No, I don’t mean just during holiday shopping; I’m talking about the countless celebrations we cherish throughout the year, like birthdays, anniversaries, and spontaneous get-togethers. But here’s the thing—celebrating life’s meaningful moments doesn’t have to feel like emptying your savings. Here’s how I’ve come to embrace the art of creating memorable experiences without breaking the bank.   Crafting a Personalized Touch One of the most fulfilling ways I’ve found to bring…

The opinions expressed here by Trellis expert contributors are their own, not those of Trellis.​ You’ve probably heard of the rebound effect — the phenomenon where savings from increased efficiency (such as lower energy bills) are then spent on other goods that ultimately reduce the expected environmental benefit of the original efficiency efforts. In your own life, though, you’ve probably seen that it doesn’t have to work this way. Maybe you’ve set aside the money saved from lowering your energy bills by upgrading to smart thermostats or other sustainable home projects, such as installing more efficient appliances. These savings can function…

Support CleanTechnica’s work through a Substack subscription or on Stripe. Zero Emissions Noosa (ZEN) runs a highly successful electric vehicle and electrify everything expo each year — we have attended several times, exhibited our aging Tesla, and written up the experience — see here for our writeup of last year’s event. So, when I heard about ZEN’s latest project, I had to share the good news with CleanTechnica readers. Noosa Council (based on the Sunshine Coast of Queensland, Australia) is funding a new independent service by ZEN to help local businesses rein in rising energy costs and make the most…

Published on: September 24, 2025Starting with Xcode 26, there’s a new way to observe properties of your @Observable models. In the past, we had to use the withObservationTracking function to access properties and receive changes with willSet semantics. In Xcode 26 and Swift 6.2, we have access to an entirely new approach that will make observing our models outside of SwiftUI much simpler.In this post, we’ll take a look at how we can use Observations to observe model properties. We’ll also go over some of the possible pitfalls and caveats associated with Observations that you should be aware of.Setting up…

If you are designing your iOS app with SwiftUI, it’s essential to understand the basic concepts of Stacks, particularly HStack, VStack, and ZStack, and how to use them. In this tutorial, we will explore these three types of stacks. HStack HStack – H in HStack stands for Horizontal. This stack view arranges all the elements/views inside it horizontally. Below image has a HStack and inside the HStack we have 2 Text labels. HStack { Text (“Hello” ) .font(.title) .background (.yellow) Text (“World!”) . font(.title) .background (.green) } . padding() .background (.red) VStack VStack – V in VStack stands for Vertical.…

Learn how to set a custom working directory in Xcode to solve one of the most common beginner issue when using Vapor. What is a custom working directory?When you try to build and run your Vapor application using Xcode you might face the issue that there are some missing files, resources or Leaf templates. Don’t worry this is a very common rookie mistake, but what causes this problem exactly? 🤔Vapor is using a place called working directory to set the current environment, locate common resources and publicly available files. This working directory usually contains a Resources folder where you can…

Today we’re very happy to announce that our book Thinking in SwiftUI is updated for iOS 17, and available in both PDF as well as print. After releasing the previous edition we have held a large number of workshops and gained a lot more experience with both SwiftUI itself as well as teaching the material. Because of this, we decided to rewrite the book from scratch. The new book contains better explanations, and a lot more visuals, diagrams, and examples. During the writing of this new edition iOS 17 came out, which brought a lot of updates to SwiftUI. We…

I have one more thing to say on the relative sizing view modifier from my previous post, Working with percentages in SwiftUI layout. I’m assuming you’ve read that article. The following is good to know if you want to use the modifier in your own code, but I hope you’ll also learn some general tidbits about SwiftUI’s layout algorithm for HStacks and VStacks. Using relative sizing inside a stack view Let’s apply the relativeProposed modifier to one of the subviews of an HStack: HStack(spacing: 10) { Color.blue .relativeProposed(width: 0.5) Color.green Color.yellow } .border(.primary) .frame(height: 80) What do you expect to…
