You might wonder why I'm bothered with this subject. 

The answer is that electricity has always been part of my life; and that of my ancestors almost since it was discovered (see The McKie Family - Untimely Death).

Indeed, it has probably always been part of your life too.  It's the revolutionary discovery that has led to the modern world.  So it shouldn't it be of interest to everyone?

Joke:  How many New Yorkers does it take to change a light bulb?  Two:  One to call the handyman; and one to mix the cocktails while they wait.

Berlin

We were to drive to Poland from Berlin.  In September and October 2014 were in Berlin to meet and spend some time with my new grandson, Leander.  But because we were concerned that we might be a burden to entertain for a whole month-and-a-half, what with the demands of a five month old baby and so on, we had pre-planned a number of side-trips.  The last of these was to Poland. 

To pick up the car that I had booked months before, we caught the U-Bahn from Magdalenenstraße, close to Emily's home in Lichtenberg, to Alexanderplatz.  Quick - about 15 minutes - and easy.

A Twisted Pigs Tale

 

This is a little exercise in creative writing.  The brief was to reimagine the Three Pigs from a different perspective.   The original is a parable about the virtues of forward thinking, providence and hard work, so that only the most abstemious pig survives the metaphorical wolf.  I thought it was a bit tough on the middle pig who is just trying to find a balance between work and play.   So here is my version:

Electric Cars revisited (again)

  

Electric vehicles like: trams; trains; and electric: cars; vans; and busses; all assist in achieving better air quality in our cities. Yet, to the extent that the energy they consume is derived from our oldest energy source, fire: the potential toxic emissions and greenhouse gasses simply enter the atmosphere somewhere else.

Back in 2005 I calculated that in Australia, due to our burning coal, oil and sometimes rural waste and garbage, to generate electricity, grid-charged all-electric electric cars had a higher carbon footprint than conventional cars.

In 2019, with a lot of water under the bridge; more renewables in the mix; and much improved batteries; I thought it was worth a revisit. I ran the numbers, using more real-world data, including those published by car companies themselves. Yet I got the same result: In Australia, grid-charged all-electric cars produce more greenhouse gasses than many conventional cars for the same distance travelled.

Now, in the wake of COP26, (November 2021), with even more water under the bridge, the promotion of electric cars is back on the political agenda.  Has anything changed?
