Energy Efficiency Gains through Information Communication Technology

Information and communication technologies provide new tools that can used to enhance energy efficiency and reduce costs.

Faced with tightening budgets and a growing list of congressional and executive mandates to save energy, reduce greenhouse emissions, and enhance sustainability, federal agencies are increasingly turning to ICT to help meet these objectives.

A C2ES analysis, built on a series of case studies of federal agencies, determined that, if widely implemented, information and communication technologies could help agencies meet half of their goals for cutting greenhouse gas emissions and save more than $5 billion in energy costs through 2020.

These ICT tools include:

  • Sensors and controls to reduce energy use in buildings, which are the source of roughly 80 percent of federal emissions;
  • GPS-based systems to improve vehicle fleet management;
  • Cloud-based email and information technology services; and
  • Enhanced mobility and collaboration tools such as teleworking and teleconferencing to reduce business and training travel.

Our report, Leading by Example 2.0: How Information and Communication Technologies Help Achieve Federal Sustainability Goals, highlights federal agencies’ initial progress in adopting these technologies and outlines steps to overcome barriers to expanded use.

The report builds on our case studies of eight federal agencies: Leading by Example: Using Information and Communications Technology to Achieve Federal Sustainability Goals.

C2ES is a founding member of a new global partnership – ICT for Sustainable Energy (ISEP) – aimed at improving energy efficiency and curbing greenhouse gas emissions through the use of information and communication technologies to achieve the goals of the UN's Sustainable Energy For All (SE4All) initiative.
