with John Harrison The Price of Power
Last winter over 40,000 elderly people died from hypothermia and cold-related illnesses. Many more suffered because they could not afford to heat their homes properly. Two million people had trouble paying their fuel bills - 'bad payers' who are a growing problem for the fuel boards.
Last week Brass Tacks examined one electricity board's alternative to disconnection - a new meter which keeps you supplied only as long as you pay your debts. Tonight Brass Tacks's viewers, welfare workers, and officials from the gas and electricity industries, join John Harrison to examine the growing problems of poverty and the price of power.

Five documentaries for the nation's bicentennial. 3: Changes
Written and presented by columnist Phillip Adams 'We learnt British history, had British heroes; our parents even had British garden gnomes. And we were xenophobic too.'
The Australia of 40 years ago had laws to keep itself lilywhite and, except for the noticeable yeast of Irish
Catholicism, it was a very British place indeed. 'But,' says Phillip Adams , 'there've been some changes since then. Migrants (the "ethnics" as we called them) made us rethink everything - from our diets to our dogmas.
Today, we are as mixed as any country on earth.'
Strange then that the only people to whom the new 'tolerance' still does not extend are the oldest Australians of all: the aborigines. Will it ever? Producer BEN LEWIN
