Hillary Clinton announced her climate change policies last night. What should we make of them?
Have more than half a billion solar panels installed across the country by the end of Hillary’s first term.
To say that this policy is worded in a deliberately misleading way is accurate. The average voter knows nothing about energy or climate change. Open season for a politician like Clinton. Read the rest of this entry »
One of the easiest ways to get away with dodgy analysis of energy matters is to assume that your readers are completely ignorant about what is going on in other countries. If you live in Britain, you can point to Germany, Denmark, or any other country, and claim they are doing much better than you on renewables, climate change, or whatever you choose. If you are German, you can point to Britain. Read the rest of this entry »
In energy it is important know what to count.
Consider this simple question. Which country is number one in terms of wind energy? In terms of total installed wind capacity it is China. At the end of last year it had 114 GW of installed capacity, in contrast to 66.2 GW in the United States (BP, 2015).
China is number one, then, by a long way. Not so fast. Last year America’s wind farms produced a total of 183.6 TWh of electricity, whereas China’s produced 158.4 TWh (BP, 2015).

I thought I would put up some R code I have for mapping wind farms in Scotland. This is hopefully of use to some readers.
Scottish National Heritage publishes a regularly updated – i.e. every 12 months – data set of all wind farms in Scotland by status. It can be downloaded here, and it requires you to go through a short registration programme. Read the rest of this entry »
A list of words that most accurate describe the qualities of British energy policy debates: special pleading, vacuity, irrationality, wishful thinking, inconsistency, stupidity, innumeracy, and ultimately nimbyism. There really is nothing positive to be said for the whole business.
The answer to all of our problems is to just say no. No to nuclear. No to coal. No to wind turbines blighting the view of our mythical countryside. No to fracking. No to solar farms. The only thing we aren’t willing to say “no” to is gas and oil from Russian oligarchs and Middle Eastern tyrants with a willingness to fund Islamist barbarism. Read the rest of this entry »
Anyone who reads this blog will know that there is a relatively large number of publicly and freely available statistical data sets covering the global energy system. However, there are a number of data sets that are either not available or behind a pay wall.
Here are a few.
- The average efficiency of gas boilers in countries throughout the world. National data sets exist, but I don’t believe anyone has compiled international figures.
- Percentage of houses that have switched to electric heating by country.
- Up to date listings of all power plants in countries, with details of age, capacity, etc. (You can get this if you pay a pretty penny.)
- Average efficiencies of existing and new solar panels.
- Hourly output data for individual wind turbines. (This is currently proprietary information, as far as I understand, but regulators could easily force wind farm owners to make it public.)
- An international database of capacity factors of all power plants, including wind farms. This is how it works with nuclear power plants, with the IEAE providing annual load factors for all nukes.
- An up to date database of the coordinates of wind turbines. USGS provides this for America’s wind turbines. However, if turbine level capacity factors were available, more in depth research could be performed on both the optimal arrangement of wind farms and more reliable calculations of the spatial requirements of wind farms.
I am sure more there are more that can be added to this list, and if someone knows of a data set covering any of the above, even at the national level, then add a comment.
The UK is “running out of money to pay for clean energy“, so the Guardian informs us today. There are supposedly a number of reasons for this. Installations of heavily subsidised solar panels on houses in sun drenched Hampshire are far ahead of where the government wants them to be, and the government might have screwed up by assuming new offshore wind farms would be less productive than they actually are. I’m still skeptical of the latter claim.
But the other reason, and an indisputable one, is that the government and everyone else was wrong about fossil fuel prices.
The basic problem is this. Government funds basically pay the difference between the price of renewables and the wholesale price of electricity. But if fossil fuels get cheaper the wholesale price also gets cheaper, and this results in more money having to be spent on renewables. Read the rest of this entry »
