Wave and tidal power pilot plants have been very costly to build per kW and in the case of wave power have often suffered very high ongoing maintenance costs. This makes the average carbon footprint of current marine (tidal and wave) power nearly 100 times larger than that of wind, with very much higher delivered energy costs.
In the second week of May 2017 our small group of habitual fellow travellers Craig and Sonia; Wendy and I; took a package introductory tour: Discover Japan 2017 visiting: Narita; Tokyo; Yokohama; Atami; Toyohashi; Kyoto; and Osaka.
The World is shocked by the growing death toll, that has now passed 5,000 as a result of the recent earthquake in Nepal.
The epicentre was close to Pokhara the country's second largest city with a population just over a quarter of a million. Just how many of the deaths occurred there is not yet clear.

It's finally announced, Australia will have a carbon tax of $23 per tonne of CO2 emitted. This is said to be the highest such tax in the world but it will be limited to 'about 500' of the biggest emitters. The Government says that it can't reveal which these are to the public because commercial privacy laws prevent it from naming them.
Some companies have already 'gone public' and it is clear that prominent among them are the major thermal power generators and perhaps airlines. Some like BlueScope Steel (previously BHP Steel) will be granted a grace period before the tax comes into effect. In this case it is publicly announced that the company has been granted a two year grace period with possible extensions, limited to its core (iron and steelmaking) emissions.
