Is it realistic to believe that the construction sites of the future will be completely fossil fuel free? In this episode, we examine the benefits of electrifying construction sites and the challenges of achieving zero-emissions in construction sites.     We visit the first fossil fuel free construction site in Sweden, Slakthusområdet i Stockholm and explore the differences between driving an excavator powered by diesel and an excavator powered by electricity.  James Bailey, Executive Vice President for Skanska’s West Coast region, USA talks about the experiences and challenges of working with electrical machines in the major transit project, Los Angeles Metro’s Purple D Line Extension Project.  Dr Ray Gallant, Volvo CE Vice President Sustainability and Productivity Services, USA explains what the challenges are for sites of the future to be completely fossil-free. Volvo CE is the manufacturer with one of the world’s largest ranges of electric machines for the construction industry, with the goal of making fossil-free machinery more accessible.
