The resource and power consumption of Information and Communication Technologies (ICT) increased rapidly in the last years and is still increasing. One big player regarding the energy consumption within the ICT is represented by the World Wide Web. Since it gains soaring importance in nearly every branch of industry the number of servers is also growing. This has sufficient influences on our environment. On the one hand there are the greenhouse gases (GHG) produced in the process of production of these servers and on the other hand there are greenhouse gases produced while operating the devices. In this case we have to have a look at the energy that is used to run the server. When there is no label displayed on a website we surf on, we do not know which quality of energy is used. Is it atomic, renewable or any other kind of energy? Because of this it is important to achieve some transparency. This is interesting for every stakeholder but particularly for the end user. Hence, we developed the Green Power Indicator (GPI), that visualizes this information for web users. Our tool displays the class of energy the data center, hosting the current website, is powered by. We distinguish between three classes of energy, which are described in detail below. In addition, we will go into the technical details of the extension and introduce some further developments in this context. The Add-on is also able to show the status of a website before you surf on the specific website. With this opportunity the user can decide whether to click on a green link or not. We will also inform about other approaches towards a greener web including Green Web Initiatives and other Addons. Furthermore we will give a short introduction in Eco Labels and present research results. After describing the GPI, which is based on the extension introduced in (Naumann/Gresk/Schäfer 2008), we will give some background information including the development of the tool and, in order to get an impression of the student work behind the development of the Add-ons, we will also give a description of the students’ projects on the Environmental Campus Birkenfeld.
