"Irish-led tidal energy project receives €3m in EU funding just now Irish-led consortium involving ORPC, Eire Composites, and NUI Galway to develop tidal power generators with blades made from recycled carbon fiber.

From memory tidal power has a an orders of magnitude over that of wind power due to the higher viscosity of water over air. Again from memory a four metre windmill generates in the 4 kilowatts range but a 4 metre tidal turbine in the megawatt range.

The ABC has shot itself in the foot in its pandering to extremists who blame coal for the threat to electricity supply. They lined up a pensioner who complained that she couldn't put her heater on, had to go go bed early, yadayada, all because of fossil fuels and not enough renewables.

The problem for authenticity was- this pensioner lives in Tasmania, where power is 100% renewable: 82% hydro and 18% wind at the time she was whining for the camera.

There’s a link to the Rance tidal power station which has been going since 1966.

Even though 100% of Tasmanian power is renewable if there's a shortage of supply in the Victorian market the price will rise (even if the shortage is an artificial Green induced one). Victoria has a much larger market than Tasmania so will tend to dominate prices. The way that energy is being sold in the US for example in Texas using commodities trading principle similar to those that were popularized by Enron are interesting. In principle they can have benefits but it can leave people vulnerable.

This situation seems to encapsulate the benefits of Localism vs Globalism.

Then there’s this one in South Korea.
