Note: if you want to read this book for free, there are now excellent HTML and PDF versions at http://www.withouthotair.com/ The print version is very well produced, however, and I didn't at all regret the £20 I paid for it.

Windfarms are becoming big business in Australia and a Senate enquiry report has just come out looking at the implications, including, most importantly, health.

You can see the whole thing here: http://www.aph.gov.au/Senate/committe...

The aspect of health that is most likely to be affected by windfarms is the psychological and physiological debilitation resulting from noise pollution and the report observes, in attempting to hear from all interested parties:

Sometimes, you just want numbers. And in this case, the numbers are free. Free!

Worm, my favorite book of 2014, featured (mild spoiler) a man whose power was organization: The bigger and more complicated the plan, the better. He becomes a villain when the government rejects his brilliant strategy to solve world hunger.

David MacKay is the nonfictional version of this. He tells you facts, then more facts, then combines the facts into a plan that would clearly work, if only everyone would cooper

If there is one question this book answers, it is this - Can we even sustain out current lifestyle with renewable energy? You may not like the answer. For anyone even remotely serious about climate change, this book clarifies all the skepticism around it, with data. SEWTHA is an excellent resource to understand how different strategies for renewable energy play out, and how beneficial they are. David creates 2 stacks - one for consumption and one for production and illustrates how we can reduce ...more

Highly recommended! Book is highly accesisble and provides a great introduction to the topic. If you belong to a group of people not believing in (antrophogenic or not) global warming you still can read it - the issues is carefully decoupled from global warming.

It's crucial that we educate ourselves about this topic.

This book feels like an engineering textbook. And this is exactly how we should approach the subject. Data, numbers, and calculations without ethics and interests. I'd love to live in a world where this is the way we talk about serious issues. But I understand this also makes this book probably unreadable or unenjoyable for the majority of our society.

This is also one of the saddest books I've read.

Hey, my first free book. It took me a very long time to get around to reading it, and even now there's bits where I crumbled because it was a bit hard for me. But I think it's an amazing piece of work. Mackay has the ability to cut clean through obfuscation and do simple things with numbers. I wish I could do this. He put me in a position where I could think about some of the things that have been baffling me for years.

An excellent book that lives up to its title if not its aim. If you want to understand what a comparably affluent, post-carbon, green future based on renewable energy might look like... and what we'd have to do to get there... then read this book. It makes clear that the problems (global warming, peak fossil fuels) we are faced with will require country-sized solutions (literally!)... and that most of the energy sources that are touted as solutions are in fact of negligable impact (biofuels, I'm ...more

The import of this book is best summed up in Mackay's own words:

"This heated (environmental) debate is fundamentally about numbers. How much energy could each source deliver, at what economic and social cost, and with what risks? But actual numbers are rarely mentioned. In public debates, people just say “Nuclear is a money pit” or “We have a huge amount of wave and wind.” The trouble with this sort of language is that it’s not sufficient to know that something is huge: we need to know how the o

This is a terrific book for anyone interested in learning about the shape of our world's energy production. What's unique about the book is how MacKay analyzes the problem of sustainable energy. His calculation is emphatically not the state of the art; it is, in fact, deliberately crude. Any old university, environmental group or coal power trade organization is likely to have more sophisticated energy models and predictions -- with their own assumptions buried deep within. MacKay's book aims to ...more

Reliance on fossil fuels for energy production can present multiple problems. First, fossil fuels are a finite resource. Second, capricious changes in foreign politics can jeopardize security of energy supply and economic stability. Third, fossil fuels alter the climate and cause global warming (unless someone happens to deny human-caused global warming). An obvious solution could be the broader use of sustainable energy sources within a country's energy production. The author, Professor Sir Dav ...more

This book offers a great overview of issues surrounding Energy policy in the UK (and the world). There is a lot of analysis of the various renewable energy sources and their potential of helping us replace fossil fuels over the next few decades. Economics of every choice is only briefly touched on, however. Still, the book offers a nice and fairly exhaustive exploration of our options and lays out most of the issues surrounding the implementation. David MacKay (author) is also first and foremost ...more

A wonderful, calculation-based overview on moving toward greener energy sources. The physicist author sets aside all social debates on choosing cleaner power sources, so the book is strictly focused on the physical possibilities for decreasing our greenhouse gas emissions. It does an excellent, clear job of explaining options to the lay reader. In order to understand why cleaner energy options are not already in place, the reader would need to search elsewhere, though, for sources on the economy ...more

Manny wrote a beautiful sentence outlining the summary of the book.

Reading this book was like meeting someone, falling madly in love, and finding out she's got a terminal illness, all in the space of twenty minutes.

We know that there is no way we can sustain our energy needs by burning more fossil fuels. This book carefully analyses each renewable energy source, and stacks them against the fossil fuels that we burn. Unfortunately, any single renewable source like solar or wind is not sustainabl

Great book for anyone, who is interested on how alternative energy supply and potential benefits can be quantified. Reader can get an understanding, perhaps approximate, of how much energy can be derived from the renewable sources, how this compares to the current demand(author has taken as an example England - but the physics of process remains the same everywhere), and how much area will need to be covered in order to satisfy the daily needs of typical person. That's definitely the type of inf ...more

We’ve heard the buzz of energy saving. “Plugging off your unused charger can save the planet,” says a green-colored poster in your town. Or your colleague bragged, “I became veggie because of scientific reason: energy and carbon footprint.” Then questions might have popped in your head. “Is it true? Can all those things save the world? Or are they just another hoax made up by environmental hippies?”

We’ve also heard conflicting claims from experts within the energy debates. “All we need are rene

David MacKay FRS is a professor of physics at Cambridge University who has written a very good textbook on information theory. He was bugged by the omnipresent illiterate claims about energy and the environment, for instance, that one can save a significant amount of energy by unplugging the mobile phone charger when it is not being used (yes, you'll save about as much energy in a day as a car consumes in a second), and decided to write a book that would get the facts straight.

A book I should have read a long time ago before wasting so much time on wishful thinking about renewable energy such as offshore wind, solar etc. The author compares our energy sinks on the one side (transport, heating, manufacturing etc) and our sustainable (lasting at least a 1000 years), zero carbon energy sources on the other, by converting both to a simple common metric (kWh/person/day) and see if they add up. The goal is to see whether we can maintain our current levels of energy use (Eur ...more

Professor MacKay died in 2016 from stomach cancer and the website that offers this book for free has not been updated since then (http://withouthotair.com) which is unfortunate to say the least. It seems to me that the website was designed to encourage people to buy and read the print book. Perhaps some enterprising engineer, computer technicial or physicist could take up the mantle and cleanup the webpage.

Best book I have read on this subject

Taking into account that this book is written in 2008. For me the presentation using Kw/day/person is something not explained before. I now know the future uphill struggle to persuade people and government change to renewables . This book is for the person who is willing to take time in understanding the basic energy units . For me it is above the usual treehugging books written with little understanding of the subject. It will be a book I will return to for

I learned a lot reading this book, but I didn't really enjoy it because I am NOT a science major. I did enjoy that the book is completely free, though. Overall, this is informative but I feel like there may be some heavy biases and inconsistencies coming from the British author. He goes on and on about how doing little things won't make a difference and then talks about unplugging "vampires" that suck energy while they are off (saving a few dollars a year). Really? Anyway, a decent read.

If you ever wanted to know what it would actually look like for us to obtain all of our energy sustainably, this is a must read. It is a little dry, and in the appendix, even gets into some hard core physics calculations, but it is very well researched and it is free on the author's website.

A clear decision to award this book 5 stars.
The author breaks down a serious subject into accessible understandable chunks and even manages to employ humour at time. The book also does not waffle, and stays on track to it's nominated goal - putting the reader straight on the rough facts on a issue which effects everyone on Earth, but is understood by very few.

What a book! It is well organised, informative and most importantly, Mackay manages to set out a comprehensive picture of the energy challenge without any political bias! In the first chapter, readers have been taken through the main areas of energy lost. From heating for homes to driving, numbers play a important role in conveying the truth. With technical chapters at the back, one can delve into the physics behind all these, I particularly enjoy reading them as they resonate with the knowledge ...more

Despite the well-structured approach to describing the problem, the outlook for sustainable energy is not a positive one. This book explains why renewables will never be able to provide 100% of the energy in the UK unless we deploy country-scale facilities - something I doubt will ever happen. This is a good example of how to walk through a difficult topic so that it is accessible for non-specialists (particularly politicians) but still offer scientific detail if the reader wishes.

This book is like one giant set of back-of-the-envelope calculations on energy consumption and production. Awesome way to get your bearings in the discussion of sustainable energy, especially if you are a quantitatively inclined person. I was surprised at how weak a lot of renewable energy sources are in comparison to coal. A realistic solution most likely will require the use of all types of energy sources, including nuclear. Some pretty shocking facts that stuck with me: the average American c ...more
