I have to take issue with the review that says the book is "Bad for Investment Advice." Power Hungry is a decent introduction to utilities, which the author broadens to include all "essential services" like water and telecom. A lot of the info is dated since this was written several years ago. But if you want to know how to invest in utilities for both income and capital gains, it's a great primer.
I've been an investor since 2000 - yes, I started just before the dot-com crash. It took me a couple of years to make back losses, and I never would have made any money if I didn't discover that SAFE stocks like utilities are the only way to make and hold on to profits. The reason I'm coming back to look at Conrad's book after first reading it 5-6 years ago is because utilities are out-performing everything else right now. I just read the investment newsletter reviews from MarketWatch, and they're rating Conrad's newsletter about utility stocks as the second highest in returns out of a couple hundred (I think) newsletters. I'm not a subscriber, and I don't usually write Amazon reviews, but it annoyed me that the first review that shows for this book is WAY off base in saying you shouldn't read it for investment advice. It's the FIRST one you should read for investment advice - if you want to actually make money!! There are thousands of fancy investing books, and lots that are better written, but in the end it's all about making money, right? 'Nuff said.
