I wish I’d done this ages ago

I picked up a Efergy real-time energy meter for £39.95 from Maplin. At this kind of price it finally seems worth it, and after bringing it home and quickly installing it, I’ve now got a sense of how much power the house uses. I’m very happy with it so far, easy to use and nice clear display. It sits in the kitchen.

With all the lights off and the fridge idling, there’s still a little over 100W needed to keep the place running, which is mad. That is going to be a bunch of plugpack transformers (wall warts) that are just making heat while doing nothing. More of those are going to get switched off now.

Turning on the kettle is a shock. I know the kettle is going to use up energy like mad, but watching the display go from 0.100 kW to 3.100 kW was more shocking than I expected.

We’ll see how it goes. I’m hoping this will give us all enough awareness to drop our consumption of electricity about 20%.

Empower Controls

I’m really pleased to say I’m embarking on some interesting work with Empower Controls to help them with some stuff that I can’t talk about yet.

From their home page:

There is a significant waste of energy in home offices, home theatres and office workstations. Devices are often left on or in a standby state. We often fail to realise that devices such as a TV, DVD player, PC, scanner, printer or mobile phone charger consume power all of the time, even when not being used or when they are in a standby state. Hundreds of millions of devices all left in a standby state adds up to a lot of wasted energy.

Empower Controls solutions allow everyday people to intelligently switch off these types of products when not in use and to significantly reduce their energy consumption, with a minimum of fuss.

It is so nice to see this awareness coming to automation. I’m delighted to be a part of this.

Reflect a moment

Tim O’Reilly comments on Google’s Renewables initiative announced this week:

The stakes are high. If our worst fears about global warming are right, we’re going to bring our technological progress to a halt unless we get new sources of clean energy. Google’s goal of beating the cost of energy from coal is critical, because coal is the default lowest-cost choice for electricity generation, and the worst from a global warming perspective.

And let’s be clear, the internet industry we know and love is a huge consumer of power. I love Nick Carr’s estimate from last year that a Second Life avatar consumes almost as much energy as a real human. While Nick’s calculations are provocative rather than authoritative, he makes a good point. Our electronic lifestyle has hidden, off-the-books costs. Google is very smart to acknowledge this fact.

Thanks Tim (and Nick). Beautifully put. Point made.

And remember, if we just ignore this, we end up back at Web 0.0, with either no electricity, or no livable planet.

Get the DVD of An Inconvenient Truth. Watch it again. — and make sure to watch the updates a year later. See? Climate change is accelerating. Bickering about who’s fault it is so 2005. We move on now. We fix this.
