David MacKay, chief scientific adviser to the UK Government on Energy and Climate Change, will speak at 3:30 p.m. April 6 in UCSB’s Kohn Hall.

MacKay will discuss his new book, Sustainable Energy — Without the Hot Air, a guide to energy consumption and production options.

MacKay’s book is a 2009 best-seller and has been called “the book to read” by Bill Gates to get an overall view of how energy is used, where it comes from and the challenges in switching to new sources.

The event is presented by the UCSB Institute for Energy Efficiency and will be Web-casted on the institute’s Web site.
