It doesn’t take a home renovation to realise substantial savings on your energy bill. Small, inexpensive changes around the house can yield a surprising return on investment, as one system analyst found.
Gordon Hudson wanted to make his home more energy efficient and save money in the process. The efforts of he and his wife, documented at the computer enthusiast blog Extreme Tech, are an excellent case study in how incremental change can have a big effect.
Gordon’s day job is designing and building analytical systems; approaching his home as a system to be studied and improved upon, therefore, wasn’t a huge leap. The first things Gordon and his wife did in a quest to lower their energy use were the obvious things most people would attack first: consciously turning the lights off, turning down the thermostat in the winter, taking colder showers. After a year of sweater wearing and cold showers they had only reduced their energy consumption by a mere 6%, which is a great rate of return for a savings account, but a terrible one when the price is a year of shivering post-shower moments.
The end result of their incremental efforts over several years was a drop of over 50% in their energy bill. The return on investment for their minor home improvements was under five years, a great return for a project with such a high rate of savings!
