Progressive Web AppsIn the age of climate change and growing digital consumption, sustainability is no longer limited to physical industries. The internet itself has a carbon footprint—with data centers, servers, and millions of websites consuming vast amounts of energy every second. This is where sustainable web development comes in. Building “green websites” means designing and developing digital platforms that are energy-efficient, fast, and eco-friendly. Beyond environmental impact, sustainable websites also improve performance, accessibility, and user satisfaction.
