The easier content is to find, the fewer pages a user has to load to locate information. This means fewer server requests are made and that unnecessary page elements — like photos and videos, which take up a lot of bandwidth — don’t load, either. These small energy savings accumulate over time.
Sustainability and page speed go hand-in-hand. When your website runs more efficiently, you use less processing power, which means that your site uses less energy and will have a lower carbon footprint. Your customers expect to get the content they want instantaneously, and efficient pages load more quickly, reducing your site's bounce rate and keeping customers engaged and satisfied.
Design & User Experience
Sustainable design is design that is efficient and accessible. Creating good experiences for both mobile and desktop users improves accessibility because it makes it easy for people to access your site no matter what hardware they have. Mobile-first web design also helps you avoid loading large assets designed for desktop machines, which improves your site's speed and energy efficiency.
The servers that store the files that make up web pages require power 24 hours a day, so the single most impactful thing you can do to move toward a more sustainable website is use a hosting provider that runs on 100% renewable energy.
