Energy efficiency has become an important part of how internet programmers think about building the web. Data taken out of existing databases is used to produce more efficient structures and ensure a cleaner surfing experience for the user. In order to ensure the energy efficiency of our own extension, we also draw our data from established datasets, instead of wasting additional energy by scraping them again ourselves.
