Engineer Saul Griffith wants you to ditch oil and gas from your everyday life.

Sounds too hard? His latest book is a step-by-step guide on how to do it. As he says, tradies will save the world, and he outlines a plan to replace fossil fuels with electricity that is generated in a renewable manner.

The Wollongong resident breaks his tips down to five of your largest forms of energy usage: where you get your electricity, how you heat water, how you heat your home, how you cook, and how you get around.

He recommends installing solar and batteries, electrifying your hot water system, ditching gas heaters, installing an induction cooker and replacing your petrol car with an electric one.

Mr Griffith admits that these five transformations would be beyond the reach of most household budgets all at once, so instead recommends upgrading as your old appliances and vehicles reach the end of their working life.

He points out that any higher costs for electric products can be offset by lower bills in the future, particularly if you are using solar power to run your home and power your vehicle. And the book has the graphs to prove it.

Mr Griffith adds that more needs to be done from a public policy viewpoint to encourage the electrical transition. He also criticises banks and other financial institutions for not taking energy costs into account when lending for homes, renovations and vehicles.

It is hard not to be caught up in the author’s infectious enthusiasm for the subject matter, making the book a read that is as enjoyable as it is informative.
