Matt Simmons, RIP

A reader emails to alert me to this news:

Matthew Simmons, an international oil expert who most recently focused on developing renewable energy from the waters off Maine, died Sunday night of an apparent heart attack, his office is reporting. He was 67.

Simmons founded the Ocean Energy Institute in 2007, hosting a grand opening of its new office last month in Rockland. The goal of the think tank and venture capital fund was to attract investment in research to make Maine a global leader in offshore wind and other ocean energy sources.

According to police reports, Simmons suffered a heart attack while in a hot tub at his home on North Haven. An autopsy is planned for today in Augusta, according to the Knox County Sheriff's Office.

Simmons was a leading energy investment banker, a former energy adviser to President George W. Bush, and author. He wrote the 2005 book “Twilight in the Desert: The Coming Saudi Oil Shock and the World Economy,” which laid out an argument that the world was approaching peak oil production.

Notwithstanding this, I am deeply shocked and saddened by Matt's untimely end.  He made a difference,  and in particular was an enormous influence on me, even where I ended up differing with his view.  Here's an interview I did with him back in 2005.
