On February 16th 2024 Wendy and I set-forth on a 20 day trip, revisiting old haunts in SE Asia.
From Hong Kong we made a brief side-trip to Shenzhen in China then embarked on a Cruise, sailing down the east coast, south, to Singapore where we spent a few days, before returning home: [Hong Kong; Ha Long Bay/Hanoi; Hoi An; Ho Chi Min City (Saigon); Bangkok; Ko Samui; Singapore]
In April 2010 we travelled to the previous French territories of Cambodia and Vietnam: ‘French Indochina’, as they had been called when I started school; until 1954. Since then many things have changed. But of course, this has been a region of change for tens of thousands of years. Our trip ‘filled in’ areas of the map between our previous trips to India and China and did not disappoint. There is certainly a sense in which Indochina is a blend of China and India; with differences tangential to both. Both have recovered from recent conflicts of which there is still evidence everywhere, like the smell of gunpowder after fireworks.
In Sicily we hired a Jeep to get from Palermo around the island.
I had my doubts about this steed. Our two big bags wouldn't fit in the boot. One had to be strapped in on the back seat - a bit disappointing.
At above 130, the speed limit, there's something odd about the steering – so much so that I stopped quite soon to check the tyre pressures. I was regretting my choice.
Reassured about the tyres we set off again.
On the plus side the fuel consumption seemed OK and the zoned climate control worked well.
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?
