Being Bold With Renewables.

Its now dawning on an increasing number of people that the renewable energy sources of choice aren't going to hack it in the future.

Wind power only produces its full capacity for a fraction of its availability. Usually, when its very cold outside, we're experiencing a high pressure system with low winds. We very rarely have Arctic-style blizzards, where it's extremely cold and windy. Most snowfall and frost for instance is coupled with low winds.

Solar experiences similar issues: cold weather happens in winter (obviously), but in winter we have short days and long nights, so energy production is curtailed. Happily for solar, we sometimes experience cold weather with clear conditions, which at least helps with energy production. Sadly in winter the sun is low in the sky and is extremely weak.

Wave power could be worthwhile, if it could be harnessed in a safe manner. Unfortunately we often experience huge storms which threaten wave power installations.

So, what do we do?

We look at a naturally occurring naturally cyclic phenomenon: the tides. The Severn barrage has been on and off for years, generally opposed by the bird-loving naturalists.
Well I'm sorry, there isn't anything there that can't fly off and find another feeding ground elsewhere along the UK coast. Its time the strategic national interest was put before a bunch of birds.
Lets start thinking of us for a change and get something in place that will generate regular zero-emission energy. The major upside of tidal energy production is its predictable, so that conventional fossil fuelled power stations know when to be online to take up the slack when the tide has gone out.

Interesting New Predictions for Global Cooling at WUWT.

I've ranted on this blog and elsewhere for years that the current CO2-driven global climate models were wrong. I've always maintained that we are at the mercy of our closest star, that ball of burning gas at the heart of our solar system, the Sun.

I'll tell you for why; its because I know the awesome power of the Sun. I'm a lapsed Ham Radio operator and one of the crucial things in obtaining reliable global contacts using short wave radio (in the days before satellites) was to be up to date with Solar Activity and where on the solar cycle we were. The sun you see is so powerful, even 93 million miles away, that it energises our upper atmosphere in such a way that you can bounce radio waves off it, just as you can bounce radio waves off a solid satellite dish. Imagine: a layer of gas and particles so energetic they have a similar property to a sheet of metal... that's pretty energetic! Mind you, that's just the invisible effects. All you really have to do is sit out in the sun on a sunny day, or get into a car left out in the sun to understand there's a fair bit of energy being pumped into that small space from its origin, so many million miles away.

So its a no-brainer for this Johnny average to assume that there is so much energy hitting the Earth from the Sun, that changes in the Sun's energy output would far and away swamp any man-made effects, such as the increase in CO2.

This report by David Archibald at Watts Up With That on the Norwegian paper is an interesting one, especially for it's predictive and apparently quantative nature. If global temperatures do change as predicted by 0.21C per year of solar cycle, it would (a) be immediately provable and (b) historically provable by previous solar observations. It will be interesting to see how this theory fares in it's predictions.

The sceptic in me says that temperatures are hardly likely to fall in such a steep way, due to the heatpump effects of the oceans, but along with this report by Dr Nicola Scaffetta, the Solar-activity-based models seem to be making a better job of reporting global temperatures than the CO2-driven models.

As an aside, and sort of linked to this thread, are the ongoing studies to see if particles from the Sun have an effect on cloud formation. CERN's cloud experiment is one such example. Water vapour is the most prolific "greenhouse gas" we have and even moderate effects on its production will overwhelm the CO2 models.

Only time will tell of course, but all the while we are pumping billions into what may be one of the largest global white elephants in history.

Here's a parting though: Instead of pumping billions into the reduction of CO2 at source, why can't we pump billions into the reduction in the need for energy at the point of use? If for instance we put those billions to use insulating existing and future houses to Arctic standards, we would reduce the need for energy which satisfies the CO2 proponents and also guard against the global cooling predicted by the solar observers. Hedging your bets and picking options that cover both scenarios would be the sensible and logical option, but naaa, governments don't do sense.

Bailouts: Where does the Money go? QE: does it make sense?

All of this money we've borrowed to bail out Greece and others, including the latest failing Bank or whatever, just where does the money end up?

Are we just pushing money into dodgy banks that instantly gets handed over to good banks? Are we being robbed blind to support the uber-rich?

Just saying.

Because no-one in the media has ever explained where the money eventually ends up.

I also have a question about quantative easing: if we make more money available basically out of thin air, doesn't that devalue the currency already in circulation? For instance if I had £10 worth of hard assets, if I'd lent out £10 in cash to 10 people (each effectively having £1) each person would have effectively £1, but then if I decided to lend out another £10 to another 10 people, wouldn't that original £10 be worth half its value, because I've still only got £10 to repay to people(effectively £10 spread across 20 people is 50p each)?

Of course QE hits me personally, because if the pound is effectively devalued, then it makes imports from Japan and China more expensive, which hits the business I work for. It makes foreign sourced parts more expensive and reduces margins, therefore it puts importers out of work. Of course the upside is our exports become cheaper. But then again, whos buying? China? Maybe for now, but when their industry masters quality control and starts to manufacture proper quality luxury goods, we'll be well and truly buggered.
