Al Gore could become world's first carbon billionaire
Al
Gore, the former US vice president, could become the world's first
carbon billionaire after investing heavily in green energy companies.
Last year Mr Gore's venture capital firm loaned a small California firm $75m
to develop energy-saving technology.
The company, Silver Spring Networks, produces hardware and software to make
the electricity grid more efficient.
