Hugh Archibald White was born and brought up in Calgary, Canada in the 1940s and 50s. He gave me a run-down on their almost universal dependence on coal, illustrated with some great anecdotes about his grandfather, a coal and gas merchant, including:

- the vastness of Canada’s natural resources
- the railways and development
- low prices and infinite availability of fossil fuels
- Canadian winters, minus 20°C for half the year
- why you didn’t insulate your house

Sorry for my sound quality – I used the wrong mic – doh! But Hugh’s quality is good.
