I’m very glad to see the publication of a book called Sustainable Energy – Without the Hot Air. Don’t be fooled by the cover — this is book is a lively look at sustainable energy.
I liked the way Freakonomics is to economics: an accessible, meaty, by-the-numbers look at the physics and practicalities of energy. MacKay, a Cambridge Physics prof, approaches the subject of carbon and sustainability with a scientific, numeric eye.”Boing Boing “This is to energy and climate what
This book is full of information — lots of numbers to digest and many colorful graphs. Best of all, the entire book is available as a free 10MB PDF download so you can start reading immediately.
I liked the MacKay’s summary of the second part of the book “Making A Difference”:
First, we electrify transport. Electriﬁcation both gets transport off fossil fuels, and makes transport more energy-efﬁcient. (Of course, electriﬁcation increases our demand for green electricity.) Second, to supplement solar-thermal heating, we electrify most heating of air and water in buildings using heat pumps, which are four times more efﬁcient than ordinary electrical heaters. This electriﬁcation of heating further increases the amount of green electricity required. Third, we get all the green electricity from a mix of four sources: from our own renewables; perhaps from “clean coal;” perhaps from nuclear; and ﬁnally, and with great politeness, from other countries’ renewables. Among other countries’ renewables, solar power in deserts is the most plentiful option. As long as we can build peaceful international collaborations, solar power in other people’s deserts certainly has the technical potential to provide us, them, and everyone with 125 kWh per day per person.
