The European Commission is organising a conference on sustainable ICT, smart grids and smart cities. The event will be opened by Vice-President Kroes and Commissioner Oettinger. It will bring together policy makers and stakeholders such as telecom companies, energy providers, regulators and consumer organisations. It will provide a platform for discussing the challenges of deploying smart grids. By exchanging best practices, the conference will look at the role ICT can play to make our cities greener. It will also touch upon the important issue of how to deliver transparent metrics around the positive contribution of ICT to solving our energy and climate problems.
