More to discover ↗Green hydrogen is made by using renewable electricity to split water into hydrogen and oxygen. It could help cut emissions in some industrial processes, but making, storing and using it takes energy. Understanding those trade-offs helps explain where hydrogen is useful—and where direct electrification is simpler.

A smart meter measures when electricity is used, while a time-of-use rate changes what electricity costs at different times. Learn how the two work together, what to check on a bill, and when shifting household tasks may help.
Read article · 4 min↗A basic home energy audit helps you spot where energy may be wasted before you buy new equipment or make major upgrades. Start with your bills, walk through each room, check for drafts and review heating, cooling and everyday devices. Then turn your observations into a practical plan.
Read article · 4 min↗Insulation slows heat moving through walls, roofs and floors. Air sealing limits unwanted drafts through gaps and cracks. Learn how they differ, where each helps and why a comfortable home may need both.
Read article · 4 min↗A heat pump uses electricity to move heat rather than create it directly. Here is how the cycle works in winter and summer, what affects comfort and efficiency, and how common home systems differ.
Read article · 4 min↗Lithium-ion batteries and pumped hydro both help balance electricity supply and demand, but they store energy in very different ways. Here is how each works, where each tends to fit, and why the choice depends on more than storage capacity.
Read article · 4 min↗Both home batteries and backup generators can keep essential devices running during a power outage, but they solve different problems. Here is how to compare their power, runtime, everyday uses and practical limits.
Read article · 4 min↗A wind turbine turns moving air into electricity, but its output changes with wind speed, weather and operating limits. Here is how the main components work, why a breezy day does not guarantee steady production, and how grids make use of variable wind power.
Read article · 4 min↗You can make a useful first estimate of rooftop solar output with three inputs: system size, local peak sun hours and an allowance for everyday losses. Here’s how the calculation works, what it leaves out and how to make the estimate more realistic.
Read article · 4 min↗A solar panel does not need the sun’s heat to make electricity. Its cells use light to set electric charges in motion, then an inverter makes that power useful in a home. Here is the process, from the first photon to the wall socket.
Read article · 4 min↗Electricity has to be supplied at nearly the same pace it is used. Here is how grid operators manage that balance, what happens when wind and solar output changes, and how storage and flexible demand can help.
Read article · 3 min↗A kilowatt tells you how fast energy is being used or supplied; a kilowatt-hour tells you how much energy has been used or supplied over time. Learn to read appliance labels, electricity bills, battery capacities and solar ratings without mixing the two up.
Read article · 4 min↗A promising product idea must appeal to people, work reliably and support a sustainable way of delivering it. Learn how to test desirability, feasibility and viability with a simple example, then use what you find to improve the concept.
Read article · 4 min↗A product can be convenient for most people and still cause avoidable problems for others. From confusing consent screens to smart devices that stop working without an app, these common design mistakes show where good intentions fall short—and what teams can do differently.
Read article · 4 min↗A product can feel helpful without collecting every detail of a person’s day. Privacy by design starts with a simple question: what information does this feature actually need? From smart-home sensors to travel apps, decisions about data collection shape both the user experience and the risks a product creates.
Read article · 4 min↗A product’s impact begins before anyone uses it and continues after it is discarded. Life-cycle thinking helps designers examine materials, manufacturing, transport, use, repair and end-of-life choices together, so an improvement in one stage does not simply shift a burden to another.
Read article · 4 min↗A product’s useful life depends on more than the durability of its outer shell. Screws, replaceable components and clear repair information can make the difference between fixing a fault and replacing the whole device. Here is how those design choices work together.
Read article · 4 min↗3D printing and injection molding can both turn a product design into a physical object, but they solve different problems. Learn how to choose between them for early prototypes, design testing and repeatable production.
Read article · 4 min↗A product can work beautifully as a prototype and still be difficult to make at scale. Design for manufacturing and assembly brings production questions into the design process early, helping teams simplify parts, plan how they fit together, and check whether a design can be built consistently.
Read article · 4 min↗A product’s material affects how it looks, feels, wears and can be repaired. Learn how designers compare common materials, test real-world use and make trade-offs that fit a product’s purpose.
Read article · 4 min↗A product can have useful features and still feel difficult to use if people cannot find them. Learn how clear labels, sensible groups, navigation paths and simple testing make websites and apps easier to explore.
Read article · 4 min↗A digital design system gives teams shared building blocks for making websites and apps. Here is what it contains, how it differs from a style guide, and how to tell whether the work of maintaining one will pay off.
Read article · 4 min↗Why do some products feel obvious while others require a manual? Affordances make actions possible, signifiers show where to act, and feedback confirms what happened. Together, these design principles can make everyday devices easier to learn and more forgiving to use.
Read article · 4 min↗A product can look intuitive yet feel awkward after a few minutes of use. Explore how designers think about body size, control placement, grip and sustained comfort—and why testing with different people matters more than designing for an imaginary average user.
Read article · 4 min↗Accessible design starts with a simple question: can people with different abilities use this product to do what they came to do? Learn how flexible controls, clear feedback and testing with users can improve everyday technology.
Read article · 4 min↗A small usability test can reveal where a design confuses people, but only if participants can try it without being guided toward the “right” answer. Here is a practical way to prepare tasks, ask neutral questions, observe behavior and turn what you learn into design improvements.
Read article · 4 min↗A rough sketch and a polished interactive model can both be useful prototypes, but they answer different questions. Learn how to choose the right level of detail, test ideas efficiently, and avoid mistaking a convincing demonstration for a finished product.
Read article · 4 min↗The first workable idea is rarely the only one worth exploring. A few structured ideation methods can help teams create genuinely different concepts, compare them fairly, and choose what to develop next.
Read article · 4 min↗A user journey map shows what someone is trying to accomplish, what they encounter along the way, and where the experience becomes harder than it needs to be. Learn how to set a clear scope, map the steps, spot friction, and turn observations into practical design improvements.
Read article · 5 min↗Personas describe the people a product is designed for. Jobs to Be Done describes the progress those people are trying to make in a particular situation. Learn when each approach helps, where it can mislead, and how to use both to make better design decisions.
Read article · 4 min↗A useful product idea often starts with a small frustration. Learn how to choose an everyday problem, ask people about real experiences, and turn what you hear into a clearer design question.
Read article · 4 min↗A promising idea can solve the wrong problem. Learn how to define who a design is for, observe what gets in their way, set useful constraints and test a problem statement before deciding whether technology belongs in the answer.
