This post completes the determination of wind costs, and Part IV covers subsidization and emissions. Part I, Introduction and Summary, contains links to all the posts in this series.
Just about any analysis you see understates wind’s cost. In fact there can be no comparison between the costs for wind and reliable, dispatchable generation plants such as coal, nuclear and gas plants. Reliability is so important in electricity systems, and wind’s persistent erratic behavior is so problematic that any electricity it produces is not usable and is a threat to electricity system reliability.
Add capacity from reliable generation plants flexible enough to balance wind’s erratic output and a steady, reliable electrical energy flow can be provided. However there is a substantial cost associated with this. As shown in Part II, for wind to produce the same amount of useful, reliable electricity over 40 years, wind and associated balancing overnight plant capital costs are almost 3 times that for nuclear, the most expensive conventional generation plants reviewed.…
Part I yesterday provided an introduction and summary of results; this post describes in more detail the analysis approach and implementation costs. Parts III and IV will cover the full costs and other results.
As will be seen, dealing with wind is not as easy as some would suggest.
Analysis Approach
This analysis looks at a 13 year period (years 0-12) in which the demand growth and plant retirement due to obsolescence/age will be each 2% per year compounded. Assuming year 0 is 2012, year 12 is 2025. Table II-1 shows the situation at year 12.
Table II-1 – Year 12 Situation for a Year 0 Demand Level of 1.0 TWh
Using demand of 1 TWh in year 0 allows easy scaling for a particular jurisdiction. For example in 2010 the total US electricity production was about 4,000 TWh.…
This post introduces a five-part series that summarizes some of the most important information about the present and future of industrial wind power in light of the growing backlash against the industry’s taxpayer dependence. Readers are invited to add anything that I have missed.
Continuing government support for windpower must confront two questions. First, why do so many people think that we have to revolutionize our energy systems right now to avoid the consequences of running out of fossil fuels (or suffering very high costs), climate change, or other possible challenges that we might face? Note the emphasis on “right now,” meaning starting now with substantial changes in energy system directions, especially electricity systems, involving massive implementation of grid-connected, industrial-scale wind and solar generation plants.
Second, what is required for wind-subsidy proponents to agree that forced energy transformation is not feasible?…
