Bright Sparks: Andrew Cranswick, Tumu Timbers

For Andrew Cranswick, operations manager at Tumu Timbers in Hastings, the calculation was pretty simple: solar costs had dropped by about a third since they last ooked at it, and power prices had gone up by about the same amount.

If something makes financial sense, he says the board will always support it. And, as they were on a fixed price for their electricity, it was clear the energy they could generate on their own roof was the cheapest energy they could get, something more homes, farms and businesses are discovering.
