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 […]
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 […]
I’m currently in research mode looking into the next step towards energy independence. For the next investment (actually reinvestment, of savings from previous investments, particularly the electric car), I’m weighing up Battery Storage or a Heat Pump. Each have their merits. Battery storage provides a way to store excess Solar PV in summer, and to […]
The first post on the energy of Transport showed that if you want to travel efficiently, there’s nothing for it: use a bike. However, many car-dwellers have the a predictable reaction: “I see that cycling is way cheaper than driving.. But I haven’t cycled since I was seven and I wouldn’t be fit enough.” What […]
This is a simple step with quite astounding results. In 2011, after yet another spilled glass of water on a bedside table at night, my entire family bought a Bobble bottle each. They are a reusable water bottle with a charcoal filter at the top. Why am I talking about them? Because not only did […]
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). […]
It’s time to step into the light! We all use lights quite a lot. They are almost miraculous in how they enhance the quality of our lives and our ability to be productive, particularly in winter. All light bulbs generate convert electricity to light. The way that this conversion is done however, has a massive […]
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 […]
