Now the solar hot water is installed and happy, I was pondering further solar installations. The question is: is it more effective to get my own solar panels, and get green power for whatever I can’t generate myself, or just switch entirely to green power? First thing to do is reduce my consumption. My previous ... [More]
I’m not convinced that I’ll participate in Earth Hour. Don’t get me wrong, I think it’s a terrific idea for raising awareness of climate change and energy issues. But I’m already well aware of those issues, thanks, and I’m working on reducing my emissions every day, not just one hour per year. And besides, I’m ... [More]
They came with a compass. Which way’s north? Ah, thought so. Do you want it on the front, or the side? I don’t mind… front’s better — I’ll be setting a good example. Behold: a green geek. The ladder went up. The collector went up and got connected. The old tank got ripped out and ... [More]
Why don’t I listen to the collective wisdom of those who comment here? Last August, Highriser Andrew commented: “Plan now for hot water service replacement as they never break down when it is convenient. If you don’t, the temptation to just replace it with the same is great.” Last night, it broke down. When describing ... [More]
Josh sent me a nifty device for measuring the power consumption of various devices. This is something I’ve been meaning to do for some time: to see what drains power, and how much, and to see in particular what even drains power when it’s idle. So I spent a couple of hours plugging it into ... [More]
My old mate Brian once described his car as being an air-conditioner on wheels. Which got me thinking. When I go for a drive on my own, the engine in my car is moving me (75 Kg) and the car itself (1356 Kg). Therefore 94% of the energy involved is spent moving the car. It’s ... [More]
So after pondering how heat-efficient my house is (at least for summer), and my water consumption, I was thinking about the rest of my energy use. Since I don’t have air con, I’m hoping the house is fairly efficient, despite heavy use of two computers. Recent bills show usage at around 8-10 kilowatt hours per ... [More]
The No Junk Mail sticker is very effective. I rarely get anything — notable recent exceptions being an ALP brochure about the local candidate, and Coalition brochures with lots of red ink slagging off the ALP. I wonder if electoral material is exempt? (Local sitting member Andrew Robb looks a bit like an older Kevin ... [More]
What did you do in the war, grandad? Sunday is Remembrance Day, when we pause to remember the generations of young soldiers who went away to war to fight for the freedoms we enjoy today, many of them paying with their lives. Those of us young(ish) adults no longer have the threat of world (or ... [More]
