This blog entry is part of a series of posts introducing the topic of smart meter disaggregation. This specific post looks at the wider reasons for reducing energy consumption. In other words, this post explains some of the reasons which keep me up at night when I'm not distracted by work! The reasons for reducing energy consumption typically fall into one of two categories: financial and environmental. We'll focus mostly on the consumption of electricity but the arguments are mostly applicable to the consumption of all sorts of energy.
Electricity prices have risen from 2004 to today; but, when compared to data from the 1990s, today's prices are not quite as earth-shatteringly high as some news papers would have us believe.
What has caused the 35% price rise (in real terms) from 2003 to 2011? I'm no expert but let's discuss two datasets which shed some light on what's going on.
I've been - er - discussing AGW with sceptics again. One intelligent chap is making the argument that "we are chosing timeframes MASSIVELY too short for this sort of science..." His point is that the paleo record suggests that CO2-forced warmings take millions of years, not decades. This is my attempt to answer:
OK. So we need to talk about rates. Physics is good at this. To approximate the rate at which the planet warms, we need to:
