Marine

 

Wave and tidal power pilot plants have been very costly to build per kW and in the case of wave power have often suffered very high ongoing maintenance costs. This makes the average carbon footprint of current marine (tidal and wave) power nearly 100 times larger than that of wind, with very much higher delivered energy costs.

Malaysia

 

 

In February 2011 we travelled to Malaysia.  I was surprised to see modern housing estates in substantial numbers during our first cab ride from the Airport to Kuala Lumpur.  It seemed more reminiscent of the United Arab Emirates than of the poorer Middle East or of other developing countries in SE Asia.  Our hotel was similarly well appointed.

More on 'herd immunity'

 

 

In my paper Love in the time of Coronavirus I suggested that an option for managing Covid-19 was to sequester the vulnerable in isolation and allow the remainder of the population to achieve 'Natural Herd Immunity'.

Both the UK and Sweden announced that this was the strategy they preferred although the UK was soon equivocal.

The other option I suggested was isolation of every case with comprehensive contact tracing and testing; supported by closed borders to all but essential travellers and strict quarantine.   

New Zealand; South Korea; Taiwan; Vietnam and, with reservations, Australia opted for this course - along with several other countries, including China - accepting the economic and social costs involved in saving tens of thousands of lives as the lesser of two evils.  

Yet this is a gamble as these populations will remain totally vulnerable until a vaccine is available and distributed to sufficient people to confer 'Herd Immunity'.

In the event, every country in which the virus has taken hold has been obliged to implement some degree of social distancing to manage the number of deaths and has thus suffered the corresponding economic costs of jobs lost or suspended; rents unpaid; incomes lost; and as yet unquantified psychological injury.
