For my commentary on our trip to Northern India in 2009 Read here...
In October 2011 our little group: Sonia, Craig, Wendy and Richard visited Argentina. We spent two periods of time in Buenos Aires; at the start and at the end of our trip; and we two nights at the Iguassu Falls.
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:
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.
