But I can't by law give you advice, and I do make mistakes. Remember: the unexpected sometimes happens. Oddly enough, the expected does too, but all too often it takes longer than you thought it would, or on the other hand happens more quickly than you expected.

Energy Price Deflation

Solar's dramatic cost decline will herald energy price deflation.

This chart from merchant bankers Sanford Bernstein via RenewEconomy is telling.



In 2012, solar provided just 0.17% of global energy supply (more of electricity generation, of course)  In 2014, solar will produce 0.85% of global electricity supply.  Solar power production has been growing at 33% per annum for the last 5 years.   At this growth rate, the percentage will double every 2.5 years; within 10 years it will be at 17%.  Even at half that growth rate (16% per annum) we will potentially be able to produce all electricity from solar.

Of course, that won't happen.  Because (a) coal and oil producers will up their production to take advantage of high prices now if they can foresee collapsing prices ahead; and (b) silicon prices will rise (I would suppose)   But silicon prices would have to soar for the technology to become uneconomic, and in any case, there are advances in PV technology which are improving the efficiency of PV panels (double click for larger) (from here, the chart is out of date, since current technology represented by empty green circles on the chart is already at 16%)



But the likelihood of price declines in coal and oil is an excellent reason to have a carbon tax.  We do not want the last gasp of the carbon fuel producers to push up global temperatures any higher.

We are on the cusp -- the inevitable cusp -- of a switch to renewable energy.  The sooner the better.

Arctic Sea Ice

Obviously there are seasonal fluctuations (lots of ice in winter, less in summer) but year-by-year, the extend of the ice caps at each extreme are less. (Double click to see full-sized chart).  The black line represents this year's extent.  Observe how it is the lowest/second lowest since measurement began. Will we hit a new low this (northern hemisphere) summer?
