William Henry Gates III (commonly known as Bill Gates) through this Feb 2010 TED talk proposes an interesting multiplicative model of global CO2 emissions of people (P), services (S), efficiency (E) and CO2 emissions per unit energy (C).
CO2 = P.S.E.C
Not much innovation is happening to control the first three, people, services and efficiency. He believes Carbon capture of fossil fuel emissions, nuclear energy and renewables of wind, solar photovoltaic (using semiconductors) and solar thermal (using mirrors to focus energy) hold the promise to contain CO2 emissions per unit of energy generated ..
Interesting insight from the Sultan of IT who is in the process of transitioning as a saviour to prevent climate change !
Innovating to zero emissions!
