This week Insight looks at the rise in electricity prices - what's behind it, and is there anything we can do about it?

Energy bills have been rising significantly for the last five years.

Experts say different factors are behind the price hikes - higher demand,
inefficiency and ageing infrastructure to name a few. And next year the carbon tax will be in the mix.

Insight examines these factors and looks at what we can do - from an individual level to a national level - to save energy and lower costs.
