Among the large amount of resources that can be usefully browsed to better apprehended challenges and possible solutions we would recommend the two following portals:

• The website of the ICT for sustainable growth Unit of European Commission’s DG Information Society and Media, providing in particular substantial information of the policy, programme and projects related to ICT for energy efficiency and other emerging fields,
• The website of the PARADISO project coordinated by Sigma Orionis, who organised the “ICT for a global sustainable future” conference in January 2009 at the European Commission in Brussels and released a “reference document”,
• The website of the Beywatch project, aiming at ICT tools for energy efficient homes and neighborhoods.
