My Response to the Latest Renewable Heat Incentive Consultation

The United Kingdom’s Department of Energy & Climate Change has been pussy-footing around with the Renewable Heat Incentive. there is another short consultation which closes on 23rd April 2012. You can get the web link to the consultation at

I have replied to the consultation on behalf of Genersys Plc. I set out my response below:- Continue reading

Why investing in income streams from PV arrays is not such a good deal

I promised to explain today why I believe the income stream from PV panels over 25 years will not prove as good an investment as some people are led to believe. Certainly the income stream is guaranteed by the government; certainly all legal measures have been taken to ensure that the installation of PV panels will qualify for the feed in tariff; certainly the PV panels will generate electricity and certainly the electricity they generate will be properly metered and fed into the grid. However, they are not a suitable investment for securitisation in my view.

First, we have to consider the amount of electricity that will be generated. At the 25 year fixed feed in tariff of 43p per kWh (the top tariff shortly to be replaced by a tariff of half that amount) an average south facing roof covered with PV will produce an income from the government of around £1500. In the first year, that is.

Thereafter, the panels will degrade, like everything else degrades. PV installations have not been monitored for 25 years so the precise degradation in performance has not been measured properly. Best estimates are that the panels in themselves will produce 1% less electricity, on a compounded basis, year on year. That means that in ten years time the panels will produce maybe an income of £1000, rather than £1500.

Secondly, as climate change kicks in so it is likely that our summers will get hotter and hotter. That is a good thing if you like hot weather, but not a good thing for PV producing electricity. PV produces the best output at lowish temperatures. If you sit by a feed in meter and watch the production of electricity on a very hot day in July in bright sunshine you will see that electricity production is much less than in bright milder weather.

Thirdly, I expect some installations will break down from time to time. PV systems need an inverter because PV produces DC electricity which has to be inverted to AC before it can be fed in to the grid. Inverters break down and wear out and need to be replaced and there will be times over the life of a PV system when the PV array is not working because the inverter needs to be replaced.

Finally, I expect accidents will happen to PV systems, especially if the house owner is trying to sell his house and finds that the PV system is making that process hard.

The problem is not with PV, or indeed not even with the undesirably high feed in tariff. The problem is that instead of becoming a genuine micro energy investment for a home owner, PV has become a spiv type business, where unsuspecting people of good intentions are being persuaded to grant leases of their homes’ roofs for 25 years in order to profit a hard selling organisation that cares not for the environment but for their own profit.

Why Getting Free PV on your Roof is a Bad idea

The subsidies offered by the government for PV panels – panels that produce electricity – were for the past two years or so incredibly generous. In fact the subsidies were so generous that businessmen found it highly profitable to turn the subsidy into a derivative government bond. What these businessmen did was to offer the free use of PV panels on a householder’s roof so that the householder could get free electricity in the daylight and the owner of the panels would get the subsidy, paid on the basis of a metered feed in tariff. Having installed PV panels on many roofs the panel owners would sell the income as a bond offering a secure 25 year income stream to people or institutions that needed an investment.

Energy independence; we must strive for as much of it as we can achieve

One of the most vulnerable parts of a developed society is the supply of energy. If the supply of energy is disturbed, interrupted or even threatened society has to make rapid adjustments many of which result in suffering and loss of prosperity. Continue reading

Accidents will happen on oil and gas rigs, again

For the past few days theElginrig in theNorth Seahas been leaking methane. As a precaution “non essential” workers have left the rig. Methane clouds have been noted above the rig and gas concentrate six miles long has appeared as a sheen on the sea surface. Continue reading

The Incompetence of Governments

I have been running a thermal solar energy business in the United Kingdom (Genersys) for more than ten years. This deals in solar water heating panels and is a renewable energy technology, which provides almost emission free  energy. During that time I have been astonished by the incompetence of government when it comes to energy matters. Fossil fuel, or renewable, governments and civil servants do not understand what they are doing and seem incapable of making the very simple and basic decisions which would require common sense and intelligence.

We Got Two (aircraft carriers) With Nothing to Do

The United Kingdom’s ability to waste public money seems to no know bounds. Several years ago Gordon Brown decided that the Clyde shipyards should build two air craft carriers just before he left office and as a result the government is spending (I should say wasting) £10 billion on building two aircraft carriers in Scotland which will never be in service by the United Kingdom because it cannot afford to put aircraft on them. The government that succeeded that of Mr Brown is too lacking in courage to cancel the building of the carriers (and presumably if it did cancel the job it would have to pay high penalty charges to the shipyards) and so the waste goes on.
