Today, more than 50 million computer servers contribute 5% to the planet’s total greenhouse gas emissions. More than 100 million websites and web applications account for 9% of the United States’ total electricity consumption, which is more than the airline Industry or a small country like Sweden. While the web is certainly more sustainable than other mediums (print, etc.), there is a lot of room for improvement.
How do you qualify a hosting provider as a “green/sustainable hosting provider”?
Ecograder defines a green hosting provider as one that is 100% powered by renewable energy, including wind and solar. We also include hosting providers that purchase Renewable Energy Certificates (RECs). We use the green hosting directory provided by The Green Web Foundation to rate hosting providers.
Ecograder analyzes the site’s contents and qualifies a site as being mobile optimized if any of the following criteria are met:
The stylesheet declaration contains the term “min-width” or “max-width”
The stylesheet contents reference “@media”
The site returns different style.css files when the user agent string is set to emulate a mobile device.

How do I limit/lower the number of HTTP requests?
Enable proxy caching: For resources that rarely change, set caching headers for browsers and proxies. By using CSS sprites you can combine separate images into one, lowering the number of requests needed to load the graphics of a site.
