I am often asked how I got into energy saving and being green, and I confess I was highly sceptical about global warming (etc) originally.
I like optimising things; getting more out of a system for a fixed input, or using less input to get a desired output. Or both on a good day. Basically it ties in with trying to make the world a better place by the time I go to bed each night.
I like doing that with electronics, with software, and lately with energy and thus carbon.
With the electronics and software no one should be astonished that I spent quite a lot of my time working with embedded systems, where squeezing glory from a severely-constrained device is an art form and a necessity, from robots in the 1980s through to smart radiator valves three decades later (similar compute power for much less energy in this case).
It turns out that in any of those, being able to do more with less, and turn out something tens or hundreds of times faster than your rivals, is a well-rewarded skill.
Naturally, I had some side projects such as my Internet Service Provider back in the days when no one knew what email was, and SPAMmers and the modern live broadband Internet had not come to pass!
I used to run banks of computers eg Sun workstations of sufficient age that on one clear-out I had a long discussion with the Science Museum in London as to whether they might like to move my production equipment straight to a glass cabinet ... they did not have the space, alas!
Those workstations used to chomp up the kWh like nobody's business, and in summer I would end up with a cooling problem. In winter even in an old house I was never in danger of frost damage either.
My electricity bills were large, maybe two or three times that for a house of the same size, but after all I was running an ISP from home... (Still, you should have seen my phone bills in those days; I broke BT's (and my local cable company's) billing systems in interesting ways.)
And then in (late) 2007 I realised that I could do better; I could kill the annoying hot sweatiness from my home office, along with the struggling noisy portable air-con unit, and the annoying bills...
A few years ago I suddenly saw my energy bills as another performance metric that I could tweak just like optimising Lehman Brothers' derivatives calculations that I was nominally paid squillions to do.
In fact, this whole area is full of numbers and graphs and science and gadgets and interesting techie puzzles, never mind the grand+ per year that I'm saving on my energy bills or indeed that "hippy commie yoghurt-knitting greenie" conspiracy about cutting carbon footprint to help avert global warming.
From aerogel and LEDs to iButtons and thermal imaging, you should see some of the fun I've been having!
So that's really how I got going: while adding two children to my household I more than halved my energy demand and added enough solar PV to cover all the remaining, by applying my optimisation skills to (part of) real life.
But my motivation moved beyond simply the mechanics and engineering of saving electricity and gas to the much wider concern for my children's (and other's) future with climate change.
One aspect that I understand reasonably well from two decades in investment banking is risk; you should treat the value of something happening, good or bad, as approximately the cost/value of event if it were to happen multiplied by the probability of it actually happening.
So I find very frustrating the constant risk-taking with all our futures by people who obstruct action to head off the vast risks from climate change, often selfish fat white old men* who'll be long dead before the real consequences hit, just so that they can enjoy a few more rounds on the golf course. That really seems to me to be selling billions of birthrights for a mess of pottage...
