Get off the Energy Cost Treadmill with Solar, a Heat Pump and Insulation

I started this project five years ago with a simple question: how can I provide for my children’s future, whilst ensuring they have a future? That means finding a solution for life that’s reconciled with climate change, but in a way that creates wealth and positive returns. Technologies have done us all favors in this […]

Home Energy Storage 1: Batteries are the Future

At some point in the next few years, most of us will have batteries powering our houses. But what about now? And how will we know the point at which they cross the breakeven point? This post is to quantify the costs and returns so we will know that point when it comes. And it […]

Installing Solar PV

Late last year, we installed 8 Solar PV panels on our house totaling 2.2kW of generation capacity. Since then, we have happily watched our house drop off the grid when the sun comes up – the entire house powered by Solar PV. At the same time, we also installed an iBoost hot water diversion unit […]

Solar PV, the Economics

Solar PV, the Economics

There is no doubt that Solar PV has taken off in a big way in certain parts of the world. It seems, in fact, that it’s on an unstoppable trajectory. It hit “grid parity” in sunnier places in the last few years (e.g. it can generate power cheaper than other power plants on the grid). […]

The Journey to Energy Freedom

The Journey to Energy Freedom

Most people reading this will spend a good proportion of their income on energy – lighting and heating your house or apartment, running appliances, fueling your car, and other things. What if you could cut these coats to almost zero and spend this increasing pile of money on, well.. anything else? Technology is at a […]
