Off the plane we are welcomed by a warm Autumn day in the south of France. Fragrant and green.
Lyon is the first step on our short stay in Southern France, touring in leisurely hops by car, down the Rhône valley from Lyon to Avignon and then to Aix and Nice with various stops along the way.
Months earlier I’d booked a car from Lyon Airport to be dropped off at Nice Airport. I’d tried booking town centre to town centre but there was nothing available.
This meant I got to drive an unfamiliar car, with no gearstick or ignition switch and various other novel idiosyncrasies, ‘straight off the plane’. But I managed to work it out and we got to see the countryside between the airport and the city and quite a bit of the outer suburbs at our own pace. Fortunately we had ‘Madam Butterfly’ with us (more of her later) else we could never have reached our hotel through the maze of one way streets.
The fellow sitting beside me slammed his book closed and sat looking pensive.
The bus was approaching Cremorne junction. I like the M30. It starts where I get on so I’m assured of a seat and it goes all the way to Sydenham in the inner West, past Sydney University. Part of the trip is particularly scenic, approaching and crossing the Harbour Bridge. We’d be in The City soon.
My fellow passenger sat there just staring blankly into space. I was intrigued. So I asked what he had been reading that evoked such deep thought. He smiled broadly, aroused from his reverie. “Oh it’s just Inferno the latest Dan Brown,” he said.
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.
