Frontline Pioneer: Olafur Grimsson

(CNN) -- Olafur Ragnar Grimsson is currently enjoying a third term as President of the Republic of Iceland. Since first being elected in 1996, Grimsson has been a passionate advocate of international cooperation in combating climate change.

Whilst Iceland still imports oil for its transport, electricity is generated from hydroelectric power. And heating is provided by geothermal power -- an abundant source in energy due to Iceland's geographical position sitting above two continental plates.

Iceland is also pioneering the use of hydrogen power with several projects testing the viability of this renewable energy.

In his youth, Grimsson studied Economics and Political Science at Manchester University, gaining a B.A. and a Ph.D before returning to Iceland to take up a post as a professor of Political Science at the University of Iceland.

He entered Althingi, the Icelandic parliament in 1978, served as minister of finance between 1988 and 1991 and was leader of the Peoples' Alliance from 1987 to 1995.

Grimsson promotes the intelligent use of renewable energy resources and is providing world leaders with an invaluable insight into how their own economies might make the switch to more renewable sources of energy.
