The first thing Sitejabber asks of a reviewer is to offer up some tag words that broadly answer the question, "What type of website is this?", and that's normally a fairly easy one. In the case of Michael Bluejay, however, any attempt to describe his site in a few key words is likely to fall short. How do you describe the output of a man who writes with equal enthusiasm about Women Grandmasters in Chess, How Not To Get Hit By Cars, and how to run Christmas lights on batteries?

Don't be put off by the man's eccentricity, though, or his many curious hairstyles. His site continues to have some of the most useful information on the web, and is possibly the best source of useful tips on how to calculate your energy use and find ways to reduce it. He'll tell you how to get the best airfares, despite himself being opposed to air flight at all because of the environmental impact; he'll offer you up a Carbon Footprint Calculator and then produce an analysis of every other calculator on the web in order to demonstrate that his is the best (which no doubt, it is). The man is a vegan, bicycling, environmentalist who campaigns against cults and the management policies of Whole Foods Market whilst apparently finding time to be a musician and marathon runner and recognized energy efficiency guru, and he quotes someone for saying of him, "You have the personality of a wallstreet broker with the value system of a hippie."

I've discovered and rediscovered his site in pursuit of finding information about average energy costs of appliances and how to read my electricity meter. In the latter case, I was assured most certainly by someone at my local energy company, PG&E, that being an analogue device, it was impossible for me to be able to get any reliable information from simply watching the wheel in the meter spinning round. This little gem was offered after having been allegedly double checked by a supervisor.

Needless to say, I didn't believe it for a moment and shortly thereafter I found the simple mathematical formula I was looking for on michaelbluejay.com. This is the place to go, if you want to start learning about how your lifestyle impacts on your environment and your budget, and what you can consider doing to make beneficial changes.

Although I recommend the site in general, I will say that some of his articles are now getting a little dusty, and could do with updating; currently, the latest references he has are from 2009 and I don't think anything new has been added in terms of original writing here for some time. Little is lost by the lack of currency, but that does prevent me from going for the full four stars.
