David Porter of the AIP (founded originally by David Andrews as the AIEP to counter the monolithic anti market and anti chp bias of the CEGB – Ed.) needs reminding that grants for A++ fridges etc (say we offer £30 to reduce baseload from 600 to 120 kWh/yr = £750 to save 1 kW) are cheaper […]Read More
We welcome the introduction of Feed-in Tariffs for sub 5MW renewable electricity generation and thank Decc for moving swiftly to pave the way for their introduction in April 2010. The proposals have the potential to foster much wider deployment of renewable energy at the local level and to attract investment in renewable energy from groups as diverse as farmers, commercial companies, social housing providers, local authorities and communities, as well as householders. Apart from helping to meet renewable energy targets, the Tariffs will enable greater consumer choice in the market going forward. A successful scheme will also contribute to economic prosperity through the creation of quality local jobs, wider sector innovation and new manufacturing opportunities.
Today, The Times has claimed that Britain’s potential renewable resources are insufficient to meet demand, and therefore that Britain needs new nuclear plants. This is reported as having been stated by the new Chief Scientific Advisor to DECC, Professor David MacKay FRS, the author of the free online book: Sustainable Energy Without the Hot Air – though it appears that The Times invented this quote. Nevertheless, the claim that Britain cannot live on its own renewables, is also made in his book.
However, the claim is not true.
On the professor’s own (underestimated) calculation of Britain’s renewable potential, it is possible for Britain to power itself from wind and solar. Current energy demand (heat, transport & electricity), is 98kWh per person per day (245GW), and the professor’s book identifies 68kWh/d (170GW) of wind onshore and offshore, and 55kWh/d (137.5GW) from photovoltaics, which together gives 123kWh/d (307.5GW). That means that even ignoring wave, tidal, geothermal and biomass, Britain’s renewable potential supply just from solar and wind substantially exceeds our energy demand.Read More

Plans to link Europe to what would be the world’s biggest hydroelectric dam project in the volatile Democratic Republic of Congo have sparked fierce controversy.
The Grand Inga dam, which has received initial support from the World Bqank would cost $80bn (£48bn). At 40,000MW, it has more than twice the generation capacity of the giant Three Gorges dam in China and would be equivalent to the entire generation capacity of South Africa.
Grand Inga will involve transmission cables linking South Africa and countries in west Africa including Nigeria. A cable would also run through the Sahara to Egypt.Read More
2009/8/13 Gross, Robert J K Dear Colleague The UK Energy Research Centre Technology and Policy Assessment theme (www.ukerc.ac.uk) is hosting a workshop for stakeholders from across the energy arena to help define its priority research areas for the next 5 years. We very much hope that you will be able to attend and contribute. The […]Read More
” The Grand Inga dam can provide 2/3 of African power needs and some of Europe’s”
While integration – meaning electrical inter – connections of neighbours – on the
one hand may enable cheap electricity, on the other, it can cause dependence.
Therefore, to avoid a single source dependency, it might be seen as a better
solution, to use less favourable resources inside a given country, and accept higher
costs and other disadvantages. Another way out of this dilemma is diversification of
interconnections. Therefore regional integration may be more attractive when the
number of participating countries rises.
In some cases, regional integration is the only reasonable way of using known
resources which are too big for a national approach.
An extreme example is the hydropower potential near Inga, by the Congo River, in
the Democratic Republic of Congo. The African Power Pools have been formed in
order to erect large scale regional integration projects – leading in a structure one
may call an African Supergrid – to be able to handle the tremendous amount of
electricity which could be produced here at very low prices, and which would be
enough to deliver two thirds of the current African consumption. But the huge
capacity makes it difficult to bring the different objectives together.Read More
Plotting the performance of a technology against the money or effort invested in it most often yields an S-shaped curve: slow initial improvement, then accelerated improvement, then diminishing improvement. These S-curves can be used to gain insight into the relative payoff of investment in competing technologies, as well as providing some insight into when […]Read More
Great article on the present complete inability of economists and politicians to see what is actually going on: See full thing at: http://www.onlineopinion.com.au/view.asp?article=8817&page=1 It is fascinating to watch the behaviour of our political and business leaders as they attempt to cope with the world’s deepening financial crisis. It is becoming clear that they don’t […]Read More
