I detect little attention in the programme to the massive social and environmental impacts of building geothermal power stations in rural areas. (newscientist.com)
It's the Nesjavellir Geothermal Power Station in Iceland. (climate.uu-uno.org)
Other interesting places to visit include the hydro power station at Atiamuri and the Wairakei Geothermal Power Station further south. (acrossnz.com)
