Pierre Delforge, Director, High Tech Sector Energy Efficiency, San Francisco

Pierre Delforge

I joined NRDC in 2010 after working for 20 years in the I.T. industry. My focus at NRDC is to reduce the energy consumed by information technology and consumer electronics in spite of their rapid growth. While information technology has a tremendous potential to transform the way we live and work and help the world transition towards a low-carbon economy, the global explosion in the number of electronics devices and in the "cloud" continues to make their energy efficiency a critical priority.

I spent the early part of my career in the UK and France, and moved to the Silicon Valley in 2004.
