Renewable energy in 1 tiny Scottish island

Driven by Dollars and Sense: As the world slowly moves away from using fossil fuels for electricity, one tiny Scottish island has proved it’s possible to rely almost entirely on renewables. The inner Hebridean isle of Eigg used to get its power from diesel generators. But in 2008 its residents launched the world’s first electricity system powered by nature, and the Crowdscience team wants to know exactly how they did it, and whether such a model could work in other places with no national grid? Marnie discovers that the community is key to the success of this project, meeting the maintenance men who taught themselves to install equipment and solve any problems themselves, and hearing from residents who’ve changed their habits to use less juice. With the mainland more than an hour away by a once-daily ferry, this kind of resourcefulness is vital. Hydroelectric generators harness the power of running water and are complemented by wind turbines and solar panels on peoples roofs, meeting 95% of Eigg’s energy needs. Now others are learning from this unique experiment and we meet the Malawians who were inspired after visiting Eigg. A solar grid in the village of Sitolo has provided power to thousands of people, and the people who designed it are planning others. Thanks to Eigg residents: Sue Hollands, Maggie Fyfe, Eddie Scott, Bob Wallace, Greg Carr. 

My comment: I wonder how much energy is derived from wind/solar power and how economic it has been, what is the payback period? Scotland has a very high proportion of windmills supplying power for the U.K. They are a blot on the landscape however to most and a hazard to flying swans, other birds and mammals no doubt, not to mention the noise near by.

  • Really Mike, that is £16,000 per person. So the UK as a whole would need to spend 70 million x £16,000 which is 1.12 Trillion, plus the cost of the backup diesels to generate 350 GW (70 million x 5 kW) perhaps divided by 2 per household, about another £2 Trillion. It makes the nuclear 150 GW at about 800 billion sound positively cheap! There is still the rebuild of the network of course (£3 Trillion), whichever option we choose.

    It is fairly obvious that all this is impossible in any “quick” timescale, all the resources are simply not available on this scale, labour, metals, plastics, road materials, plant, design effort or even Tax revenue. Good luck with that. You then need to add the cost of transport vehicles, heat pumps, insulation and everything else. In addition, we need to build at least 500,000 houses a year to keep supply and demand in sync.

    Poor Boris is nearly as confused as Alice in Wonderland!
