Travel

Ireland

 

 

 

 

In October 2018 we travelled to Ireland. Later we would go on to England (the south coast and London) before travelling overland (and underwater) by rail to Belgium and then on to Berlin to visit our grandchildren there. 

The island of Ireland is not very big, about a quarter as large again as Tasmania, with a population not much bigger than Sydney (4.75 million in the Republic of Ireland with another 1.85 million in Northern Ireland).  So it's mainly rural and not very densely populated. 

It was unusually warm for October in Europe, including Germany, and Ireland is a very pleasant part of the world, not unlike Tasmania, and in many ways familiar, due to a shared language and culture.

Renewable Electricity

 

 

As the energy is essentially free, renewable electricity costs, like those of nuclear electricity, are almost entirely dependent on the up-front construction costs and the method of financing these.  Minimising the initial investment, relative to the expected energy yield, is critical to commercial viability.  But revenue is also dependent on when, and where, the energy can be delivered to meet the demand patterns of energy consumers.

For example, if it requires four times the capital investment in equipment to extract one megawatt hour (1 MWh) of useable electricity from sunlight, as compared to extracting it from wind, engineers need to find ways of quartering the cost of solar capture and conversion equipment; or increasing the energy converted to electricity fourfold; to make solar directly competitive.
