Minimal checking procedures by the authorities could deter any attempts. You are probably right. Minimal checking procedures by the authorities could deter any attempts.

One of these: http://www.generatorplace.com.au/index.php?option=com_content&view=article&id=13 would cost about 70p an hour (0.64l * 110p/l) to run at rated 1600W output. So nil margin (1.6kW * 44p/kWh = 70p)without including the capital cost of the kit - lets be generous and assume it has been stolen! What am I missing? Any power levels dramatically above these I'd expect to be picked up by some pretty straight forward account monitoring. I still think the criminals would look for easier pickings. One of these:

Maybe George is worried about people connecting generators instead of PV? That was tried in Spain, I gather, and rumbled when they were left on at night. On the storage point, I agree. I can see R&D surprising folk about storage, in a positive way, in the years ahead. On the “crims” point, I wonder myself. Maybe George is worried about people connecting generators instead of PV?

One thing which I would like to point out from his critique is this: "By buying electricity for 7p and selling it for 44p (if you sell power to the grid rather than using it yourself, you get an extra 3p), they'll make a 600% profit. Amazingly the government has decided not to measure how much electricity people are selling, but "to pay export tariffs on the basis of estimated (deemed) exports". Elsewhere in its report it boasts of "encouraging a risk-based approach to audit and assurance". Come on in, you crims, the door is wide " I have seen this elsewhere and I think it should be challenged. How exactly is this going to work? How is incoming 7p/kWh elec. going to be diverted back out to the grid at 44p/kWh? To my mind this will need two supply lines to the same property OR local power storage that can be cycled. I think neither are likely options for the 37pkWhr margin available. A much simpler scam would be to bypass the meter and I believe this has been done many times by the unscrupulous - I don't see how feed in tariffs change this. On the subject of local energy storage I think this is a missing piece of the PV/renewable jigsaw. I think load matching is the elephant in the room on renewables and suspect that with the FIT and appropriate financing a properly specced and invertor and battery manager desinged for cooperative working with a grid supply has a lot ot offer. Deep cycle Lead Acid kept within its operating parameters is reliable and robust established technology and I think that RandD shoukd go towards incorporating this into the FiT offering. I'd welcome your thoughts on this - and good luck with your wager! Hi Jeremy - thanks for your informed and considered response to GM.

Two main points: solar works well in strategic harness with other renewables ....you mix and match with other members of the family to get baseload, and peakload. Also, microgeneration can smooth out the load on the grid. Much of the solar generated by day in the average home is used right there in the home. Yes, noted in the blog string David.

And everything in the electrical grid is sized for peak demand: generation capacity, infrastructure, backup, etc. Thanks for your time. David. Jeremy,

In case you missed my question at the Guardian - and apologies if you’ve answered this elsewhere and I missed it:

Could you please help field find an argument I’ve been given:

Thanks for your time.

David.

I use the language of polite confrontation, not conflict. George, it has to be said, often doesn't hesitate to call someone a deluded fool where he could merely point out that he holds a very different point of view. As for anonymous blog trailers like yourself, abuse and conflict language often seem to be the default mode, sadly. In my response to George, I do not abuse him.

I remember seeing such an article by a geologist which took a fairly long view of human history and how human expansion may be linked to available energy resources. Was it you?
