Energy Myths and Realities

Vaclav Smil ´ 9 characters Free read ô E-book, or Kindle E-pub ´ Vaclav Smil Free read Energy Myths and Realities Global energy challenge When will the world run out of oil Should nuclear energy be adopted on a larger scale Are ethanol and wind power viable sources of energy for the future Vaclav Smil advises the public to be wary of exaggerated claims and impossible promises The global energy transition will be prolonged and expensive and hinges on the development of an extensive new infrastructure Established techn. In Energy Myths and Realities Vaclav Smil brings a pragmatic view to popular ideas for our energy system of the last few decades electric cars nuclear decentralized energy production peak oil carbon seuestration biofuels and wind power His key message is that energy technologies are often over hyped often ignore environmental conseuences or infrastructure reuirements and that transitions are slow His analysis benefits from an extensive and current reference list mostly journal articlesWhile Smil rightly critiues excessive technological optimism at times he overreaches Selected facts are contorted to create an energy myth for Smil to debunk dismissing those who made foolish claims as naive or incompetent As an example when Smil constructs and estimated of land use reuirements for wind power he calls out wind capacity factors used by industry and academia as overly optimistic Although the range of 20 25 percent has been freuently assumed in recent literature the most complete examination of the actual record for the EU the world s largest concentration of wind power shows that during the five years between 2003 and 2007 the capacity factor amounted to less than 21 percent This means that the cost of wind power is two thirds higher and the reduction of CO2 emissions is 40 percent lower than was previously assumed p124 Source Boccard N 2009 Capacity factor of Wind Power Realized Values vs Estimates Energy 272679 88Smil s premises are wind capacity factors and power production per unit area estimates are overstated From this he concludes that CO2 reductions potentials are much lower than often stated His first premise is misleading He spends the first part of the chapter mentioning how wind power has grown substantially in recent years and that turbine size has increased Turbine capacity factor estimates have improved along with turbine size12Smil should have used estimates for new turbine installs not the average over the several years In the same paragraph he cites capacity factors of 70% for coal and 85% for nuclear while also citing data that total electric production capacity factor is 50% of which nearly all is coal nuclear and gas These figures are incompatible The 70% and 85 figures are for newer plants not average Many plants are kept in reserve because they are older and less efficient These older plants may have capacity factors in the range of 30 40% thus the net 50% figure The same comparison should be used for wind power using new turbine capacity factors to calculate the space reuired for new turbines Using the appropriate capacity factor erases Smil s claim of overstated reduction potential It s easy to pick out overly optimistic projections of certain energy technologies and dismiss them as such which Smil does But Smil doesn t do a great job of presenting the context Were the majority of promoters overly optimistic or was it a minority within the field Did they wield any substantial wealth or political power or were they just academic exercises or toothless celebrities Jacobson s projections for all renewables by 2030 is a example of the analysis without much power Even if there was power was it used Lots of presidents have made claims for energy independence but none have expended substantial political capital to enact significant energy policy This context is important because it gets at an important piece of the energy system which Smil ignores political economy Nuclear power has been somewhat successful and has enjoyed continued immense government support greater than all end use technologies combined and in spite of substantial opposition in its early days 3Fossil fuels have had even greater political influence as evidenced by direct subsidies geopolitical maneuvering and military support 4 Even in its early days the US government was a key supporter of the coal industry despite union opposition 5 And fossil fuels remain artificially cheap compared to their societal damages largely as a conseuences of industry lobbying This is an essential part of the story of its dominance in our energy system Wind and other renewables have negligible political power compared to the fossil fuel industry It s appropriate to view the development of wind in spite of opposition from the fossil fuel industry Seeing this full context of energy would have made the book stronger It would also have helped to provide energy profiles and transition rates for other countries especially developing countries Citing historical rates of energy transitions is only partial evidence for the claim on the pace of energy transitions There is good reason to believe that many developing countries will take much less time to uptake energy technologies that took a lot of time to penetrate in the US China and India being prime examples Also given concerns about climate energy infrastructure now enjoys special attention that is historically unprecedented and it is unclear how much this attention can change the pace of energy transitions Smil appropriately places end use efficiency and high US per capita energy use as the priority before considering carbon seuestration and rightly denounces the idea of biofuels as a major source of energy for the environmental and food vs fuel issues However he advocates reducing energy intensity of the economy is there anyone who doesn t but ignores the issue of the pace and limitations of energy intensity reductions and whether these are acceptable for climate reasons Had Smil addressed this literature he may have stumbled across Tim Jackson s Prosperity Without Growth piece and related articles that make a clear case why the developed countries may have to plateau or reverse economic growth at least in several sectors to stay within climate limits Lastly Smil makes an appeal to readers to evaluate energy literature in an unbiased way While I generally agree that dispassionate analysis is a good way to do research I don t think Smil met that standard in Energy Myths and Realities He missed the political economy piece of the energy puzzle And he published through the highly partisan American Enterprise Institute which has used claims that energy transitions take time to denounce or block much needed advancement on climate policy Bias is inherent in any analysis claiming it doesn t exist is an admission of adopting the dominant perspective and in this case it means avoiding the immense ethical issues that arise around energy decisions While I look forward to reading other Smil books because of his reputation in the field I hesitate to recommend Energy Myths and Realities Instead for those looking for a technical analysis of energy transitions in the context of climate adaptation I recommend L D Harvey s Energy and the New Reality
