 Corrections to final published version (3.5.2) ```Pages 2, 18 Apologies to Jonathon Porritt for mis-spelling his first name. Page 30-31 Note 29. In the sentence, If I said "the average use of energy for car driving in the UK is 24 kWh/d per person," I bet some people would misunderstand and say: "I'm a car driver so I guess I use 24 kWh/d." replace both "24"s by "13". (24 kWh/d/p was the average use of energy for all road transport. Of that, 13 kWh/d/p goes into cars and motorcycles.) Page 43 corn to ethanol (in figure 6.11) "0.02 W/m**2" should be "0.048 W/m**2". [Details: the power production of ethanol works out to 0.2 W/m**2; unfortunately, producing the ethanol requires inputs with a power _cost_ of 0.2 W/m**2, which cancels the power produced. The only way to get net power from corn-to-ethanol is to ensure that all co-products are exploited. Shapouri et al then estimate that corn ethanol production has an 'energy ratio' of 1.24, which means that the _net_ power production of corn-to-ethanol is 0.048 W/m**2.] Page 47 add parenthesis: band-gap is lost. -> band-gap is lost.) Page 55 Map showing Kinlochewe and Bedford: Kinlochewe is shown incorrectly. The correct location is about 60km further north. Page 56 (note 56, line 8) "has a per" -> "has a power per" Page 62 line 14 from the bottom, ``0.14 million tons'' should read ``140 million tons''. Page 63 ``Denmark, where windmills generate 9% of the electricity.'' should read ``Denmark, where windmills generate 19% of the electricity.'' [Danish wind production in 2008 was 3.4\,kWh/d/p; their total gross electricity production was 18\,kWh/d/p. -source] Page 75 Last line, "5%" should read "10%". Page 81 Why are there two high tides and two low tides per day? Well, if the earth were a perfect sphere, a smooth billiard ball covered by oceans,... ... Two humps of water cannot whoosh round the earth once per day because the continents get in the way. → Why are there, in many places in the world, two high tides and two low tides per day? Well, if the earth were a perfect sphere, a smooth billiard ball covered by extremely deep oceans,... ... Two humps of water cannot whoosh round the earth once per day because the oceans are too shallow and the continents get in the way. Page 85 In the map of Northern Ireland the placename "Downpatrick" is missing its first letter. Page 120 trolleybuses consume 270 kWh per vehicle-km should read 270 kWh per 100 vehicle-km Page 131 "hydrogen gradually leaks out of any practical container. If you park your hydrogen car at the railway station with a full tank and come back a week later, you should expect to find most of the hydrogen has gone." is incorrect and should be replaced by: "hydrogen gradually boils off from cryogenic tanks to keep them cold. If you park a cryogenic hydrogen car at the railway station with a full tank and come back two or three weeks later, you should expect to find most of the hydrogen has gone." Page 133 "Rijnsdam" should read "Rijndam" Page 153 "Scandanavia" should read "Scandinavia" Page 167 "The nuclear decommissioning authority has an annual budget of 2 billion." In fact this is to clean up not only the civilian nuclear power stations but also the military nuclear-bomb-making facilities at Sellafield. The lion's share of the money is thus cleaning up military mess, not civilian-power mess. This means I have overestimated the cost per kWh of cleaning up old civilian nuclear power. Page 169-170 "after 1000 years, the radioactivity of the high-level waste is about the same as that of uranium ore." → "if we reprocess the waste, separating off the uranium and plutonium for use in new nuclear fuel, then after 1000 years, the radioactivity of the high-level waste is about the same as that of uranium ore." Page 181 Figure 25.8, caption: "one-third-filled" should read "one-half-filled". Page 192 Table 26.7. Columns 2 and 3: volumes and depths are wrong. All volumes (40, 40, 100...) and depths (20, 10, 20...) should be doubled (to 80, 80, 200... and 40, 20, 40... respectively). Page 199 Figure 26.13, last sentence of caption: "reduced" should read "reduced from". Page 204 The red box marked Transport (20 kWh/d) and the adjacent blue box marked Electricity (18 kWh/d) were both accidentally misdrawn 10% too tall. Page 205 paragraph 2, last line, "2 kWh/d/p of solar hot water," should be "1 kWh/d/p of solar hot water," Page 206 fig 27.2 Teeside should be Teesside Page 207 Last paragraph, fourth line: Waste incineration: "1.3 kWh/d/p" should read "1.1 kWh/d/p". Page 217 "the cost of decommissioning the UK's nuclear power stations." → "the cost of decommissioning the UK's nuclear power stations and nuclear-weapon factories." Page 232 "Scandanavia" should read "Scandinavia" Page 234 "250 kWh/d per day" should read "250 kWh per day". Page 238 paragraph 2: Brazilian sugarcane - See erratum for page 284, below. Page 241 Figure 31.2's discussion of the amount of carbon in the atmosphere should have clarified that the amount shown (600 Gt) is the pre-industrial amount. Since 1850, the amount of carbon in the atmosphere has increased to roughly 800 Gt. Page 246 To pulverized the rocks → To pulverize the rocks Page 260 The numeric value of the speed at which a car's rolling resistance is equal to air resistance is incorrect. "7 m/s = 16 miles per hour" should be replaced by "13 m/s = 29 miles per hour". Page 263 Fig B.1: force 7, 31 km/h → 58 km/h Page 281 line 2: depends only → depends only on Page 284 Bioethanol section: "0.02 W/m**2" should be "0.2 W/m**2". To make this section more informative I would rewrite it thus: 1 acre produces 122 bushels of corn per year, which makes 122 x 2.6 US gallons of ethanol, which at 84000 BTU per gallon would mean a power per unit area of {0.2 W/m^2}; however, the energy inputs required to process the corn into ethanol amount to 83,000 BTU per gallon; so 99% of the energy produced is used up by the processing, and the net power per unit area is about {0.002 W/m^2}. The only way to get significant net power from the corn-to-ethanol process is to ensure that all co-products are exploited; including the energy in the co-products, the net power per unit area is about 0.05 W/m^2. Page 285 End of paragraph 1: 230 square metres ... roughly 6% ...'' → 100 square metres ... roughly 3% ...''. Page 286 If 2800\,m^2 of Britain (that's all agricultural land) ... → If 2800\,m^2 per person of Britain (that's all agricultural land) ... Page 298, 299 The top line of page 298 gives 6.6 W/m^2 as the total power per unit area of the Heatkeeper house. This is incorrect. 6.6 W/m^2 is the heating power only. The total power per unit area is 12.2 W/m^2. This error is repeated in figure E.12. [Incidentally the equivalent breakdown of power consumption in my house, "after", is 6.2 W/m^2 of gas and 7.1 W/m^2 total.] Page 299 Another problem with figure E.12 is that the PassivHaus standards use a different convention for defining power: power is measured in terms of "primary energy consumption", which requires knowledge of the sources of electricity and fuel and of conversion efficiencies. This means that the PassivHaus standards are actually more stringent than the figure shows; though exactly how much more stringent depends on the fuel mix. Page 300 Figure E.13: "Text" should read "Tout", for consistency with the caption. Page 316 The equation number (G.10) is missing from the equation on this page. Page 324 line 22 "(10 kWh/d per person)" should read "(10 kWh per kg)" Page 328 line 6 ``Internationale" should read ``International".
