The teddy bear of energy sources

Solar power is the teddy bear of energy sources. What's not to like about the sun, the source of all life? Best of all: No wars have ever been fought over solar power (though I'm sure that teddy bears have been at the centre of a good few sibling battles).

Eric Curren gives a comprehensive round-up of the status of solar power at Transition Voice as at November 2010, in the U.S.

He notes that solar is cute and lovable right now because it is mostly small scale and individuals can have their own pet systems.

This will change when large scale solar becomes more common as countries like Saudi Arabia (investing $109 billion in solar over the next 20 years) start to roll out big solar generators in desert areas and upgrade their national grid networks. In Australia, Beyond Zero Emissions advocates for Concentrating Solar Thermal in their Stationary Energy Plan.

Schemes are being sketched to augment Europe's power supply from large scale solar plants in North African and Middle Eastern (MENA) countries connected to Europe by HVDC transmission lines.

Locals in MENA countries who see industrial scale solar generators and the transmission lines carrying the power to rich northern neighbours may not see solar as a lovable teddy bear. If they are given a share of the power at a price they can afford, they are likely to see solar more like a fairy godmother.

Continuing the teddy bear metaphor, Eric Cullen asks:
What will it take to help the solar teddy bear grow into a thousand-pound grizzly, ready to rip to shreds high energy costs, polluting fuels and dangerous nukes?
Now THAT'S a future I want to see!
