ACCORDING to the International Energy Agency’s new roadmap for solar power the world could be getting as much as 25 per cent of its electricity from the sun by the year 2050.
But there are some big ifs and buts. Releasing the roadmaps for the PV and solar thermal industries, the IEA’s executive director Nobuo Tanaka says:
This decade is crucial for effective policies to enable the development of solar electricity. Long-term oriented, predictable solar-specific incentives are needed to sustain early deployment and bring both technologies to competitiveness in the most suitable locations and times.
What Mr Tanaka is suggesting is that the road ahead for solar should be relaid with nice smooth bitumen with as few traffic lights, stop signals and roadworks as possible. The Rudd Government may point to its $1.4 billion funding of solar projects, announced last year, as evidence of these incentives. You might even look at the hotch-potch of domestic feed-in-tariffs currently being played with in different states.
Earlier this week a shortlist of eight projects under Mr Rudd’s Solar Flagships scheme was announced – four are solar PV (electric generated via panels) and four are solar thermal (electric generated by concentrating the sun’s rays to create heat to eventually drive a turbine).
While the Government has been doing much chest beating about the virtues of its flagship programme, the unfortunate reality is that the resultant 1000 MW of power generation is dwarfed, nay trampled on, by plans already in the pipeline for new coal power generation.
To put that 1000MW into perspective, it’s about the same as one single medium sized coal-fired power station. This list of electricity generation capacity in Australia from 2008, leaves a 1000 MW solar thermal plant sticking out like a tiny chink of light among a swathe of black coal.
When Mr Tanaka asks for a shiny new road surface for the solar industry, Australia appears to be building something which looks a bit more like a gravel path.
