BOOK REVIEW: Power of the People

I just finished reading Power of the People: America’s New Energy Choices (2007), a nice short read about the history of, current usage of, and the future possibilities for energy consumption in the United States. At 188 pocket-sized pages, the book doesn’t take more than an afternoon to thumb through. This is thanks to the concise way in which Carol Sue Tombari explains things. She writes as though you’re sitting down together to share a nice salad lunch, not stuffy, not too complicated. But in the mix, she throws in a surprising amount of information about the current energy landscape. You see, Ms. Tombari knows what she’s talking about, after years working for both private and governmental authorities on the topic of energy. So when she talks about the ways in which power utilities fell victim to disincentives for innovation when they “reregulated” in the 1990s, you can bet she saw it happen from the front lines.

Power of the People

The book is divided into two main sections of two chapters each. First, you find out why all this is important anyway. What IS the energy crisis? Then on to Energy 101, a brief discussion of the current power generating technologies and what is already possible in terms of augmenting power load both at the personal and utility level. I learned a lot about how the utilities work (and why this model is outdated). The next main section focuses on the future. What will we have to do to survive the looming power shortage? In the first chapter, she outlines the different players in the energy system, and then discusses how each is challenged by setbacks, and suggests how that challenge will have to be overcome. The last chapter outlines the future and its many possibilities.

I really liked the format of the sections, in which each technology is presented in “the good”, “the bad”, and “the balance” sections. This allows you to get a clear overview of the limitations and promises without delving too deep into science. If you are looking to implement alternative energy solutions in your life but don’t know which one fits for you, I’d recommend this book heartily. If you already have a clear idea of what’s going on, you’ll still find a nicely written essay with interesting photocopy-friendly facts to quote.

The best audience for this book, however, are those who are looking for a way to change energy consumption on a societal level. Buried within the outlines of various technologies is an underlying cry - “Innovate!”, challenging readers to help find the solutions alternative energy implementation barriers. Only a few logistic issues separate most alternative technologies from gaining wide-spread acceptance. What is the power of the future? Could you be the mind to crack the riddle?

zeroHouse - Making Your Home Work for You

Nice. No, really, everything about this concept is nice, from the idea, to the execution and the website. So nice that you’d better go check out the website for yourself, so I’m only going to provide one chart here as a teaser.

zeroHouse by Scott Specht

This house does it all. Collects water, uses high-capacity solar, makes its own compost, and looks amazing while doing it through your laptop. And you can construct one in under a weekend. How’s that for simple? It’s certainly inspiring.

BOOK REVIEW: Power With Nature

Alternative Energy Solutions for Homeowners Updated
Power with Nature Second Edition: Alternative Energy Solutions for Homeowners Updated (this review is based upon the first edition, but hey, newer is better, right?
I picked up this book while on a “shopping spree” at the library and promptly set it aside. Which is a shame, because once I did pick up this book, I read it from cover to cover. And I would do it again, except that it’s a popular item at the library, and they want it back. The story starts with a fable, a little tale designed to lull your brain into thinking that you are reading for fun, not education. All the while, it’s filling you in on all the basic details and considerations you need when deciding of off-grid living is for you. And then, if that isn’t enough, the second section of the book backs up the fable with lots of practical examples and configurations for solar, wind, and mini-hydro projects that will save you money. And it’s not written in geek-speak. Thank you, Mr. Ewing!

Thanks to this book, I now have a much clearer idea of what my little solar panel will (and will not) do. Dreams of charging my computer with only this little panel and a battery seem a bit more distant, but the new opportunities and food for thought that were provided instead were well worth that disappointment. And here’s to finally understanding the difference between watts, amps, volts, and all that jazz, which is worth another college education, at least! I cannot recommend this book enough. In fact, I’m headed to the library right now to see if they have Rex Ewing’s newest off-grid living book: Crafting Log Homes Solar Style: An Inspiring Guide to Self-Sufficiency.

2007: an Analysis of the Renewable Power Industry

Consider these facts, taken from the Renewables 2007 Global Status Report:

  • Renewable electricity generation capacity reached an estimated 240 gigawatts (GW) worldwide in 2007, an increase of 50 percent over 2004. Renewables represent 5 percent of global power capacity and 3.4 percent of global power generation. (Figures exclude large hydropower, which itself was 15 percent of global power generation.)

  • Renewable energy generated as much electric power worldwide in 2006 as one-quarter of the world’s nuclear power plants, not counting large hydropower. (And more than nuclear counting large hydropower.)

  • The largest component of renewables generation capacity is wind power, which grew by 28 percent worldwide in 2007 to reach an estimated 95 GW. Annual capacity additions increased even more: 40 percent higher in 2007 compared to 2006.

  • The fastest growing energy technology in the world is grid-connected solar photovoltaics (PV), with 50 percent annual increases in cumulative installed capacity in both 2006 and 2007, to an estimated 7.7 GW. This translates into 1.5 million homes with rooftop solar PV feeding into the grid worldwide.

  • Rooftop solar heat collectors provide hot water to nearly 50 million households worldwide, and space heating to a growing number of homes. Existing solar hot water/heating capacity increased by 19 percent in 2006 to reach 105 gigawatts-thermal (GWth) globally.

Alternative Energy is (very) ready for its time in the spotlight.  With the quick adoption rates that these numbers reflect, one can only wonder how long it will be until 50 or even 75% of our power could be renewable.
