Speaking for the motion were Paul Domjan (an energy security expert) and Patrick Moore (of Greenspirit, formerly of Greenpeace). Speaking against were Dr Caroline Lucas MEP (Green Party) and Professor Tim Jackson (Sustainable Development Commission).
The Economist's Vijay Vaitheeswaran was the humorous and effective chairman.
I found Patrick Moore amusing and forceful and thought Dr Lucas entirely unconvincing and disingenuous but was most impressed by Professor Jackson. He headed a commission that looked into the role of Nuclear Power (details here) and came to the non-intuitive (for me, at least) conclusion that pursuing nuclear is not necessarily the best current solution to our energy security and climate change needs. His reasoned, evidence-based approach to debate eclipsed Dr Lucas' over-the-top, hand-waving, alarmist style and gave me pause. I had previously been a strong supporter of restarting our nuclear programme and, although I still am, he made me think again.
I've just signed up for a copy of his report (here)
I should say that I wasn't entirely convinced by all his arguments, however. One of his pointswas a moral one (essentially that it's not right that we impose the costs of nuclear clean-up on future generations without truly accounting for the cost). However, he seemed to ignore the reasonable assumption that future generations will be unimaginably wealthier than us and the argument that it is possible to treat waste in such a way that its half-life is manageable and so put a limit on the liabilities we are imposing on the people of the future.
It was an interesting night.
