How Much Wind Energy is there? – Brian Hurley – Wind Site Evaluation Ltd.


The starting point is an estimate of the total quantity of kinetic energy in the atmosphere. Lorenz gives 1.5 x 106Joules/m2 as the quantity of kinetic energy contained in the atmosphere(1). Smil gives a figure described as the annual “solar radiation reaching the earth” as equal to 5.8 x 1024Joules, or 1.84 X 1017W, and 360W/m2(2). Annual Solar radiation absorbed by earths surface(land and sea) 2.9 x 1024Joules, or 9.19 X 1016W, and 180W/m2. Note the solar constant is 1,366W/m2. Smil refers to a source from Lorenz(1976) that “atmospheric motion” was about 2% of 3.5PW insolation. ( Applying 2% to Smil’s 9.19 X 1016W giving 1.84 X 1015W with his figure for winds below 1km 1.22 x 1015W is the right order of magnitude

Gas Turbines on the Isle of Man: A Case Study between the Manx Electricity Authority and Cranfield University. IDGTE paper at Cranfield, Thursday 19 March.

In the volatile energy market effective use of the available technological, energy and financial resources is now, more than ever, highly pursued. In a combined cycle power plant, gas turbines are the prime mover of power generation. Therefore, detailed understanding and monitoring of gas turbine performance, health condition and associated costs have a deep impact in the decision making process concerning the plant’s operational and maintenance strategy.

In this context, research collaboration between Manx Electricity Authority (MEA) and Cranfield University has been carried out since 2001 and a series of technologies and software have been and are still being developed at Cranfield University and some of them have been integrated into MEA Combined Cycle Gas Turbine Power Plant in Pulrose, Isle of Man. During this constructive and successful collaboration period, the University has been fortunate to acknowledge the industrial needs and make significant academic contributions through ongoing research projects jointly supported by both MEA and EPSRC. On the other hand, MEA has valued the complexity of asset management concerning the gas turbine and the combined cycle, therefore enhancing its trading and operational capabilities through the application of developed performance, diagnostic, trading and economic analysis software.

"UK Energy Risks – Uncertain but not Unimaginable" – Global Energy Advisory

On the 23rd of February it was reported that one of the large six utility companies in the UK lost £172.5mn, in just three months, by trading a gas position. This loss could have been against a background of relatively low gas price volatility; presumably this “increase in wholesale cost” will now be passed on to end consumers? Who trades and who pays? Who invests and who pays?
The new Energy & Climate Change Committee is today taking oral evidence from the Secretary of State for Energy and Climate Change, Rt Hon Edward Miliband MP, in the House of Commons in London. The independent Global Energy Advisory White Paper entitled: Investment Failure, Fails Customers, was circulated to the Committee earlier this week.

The paper discusses the potential risks to UK energy security which are well known within the Industry. It also asks pertinent questions regarding the costs and consequences of the energy investment/trading decisions being taken at the current time.

This discussion will be continued at the Global Energy/Advisory Super Derivatives Seminar in London on March 5th – see below for full details.

Uttlesford – the most CO2 per household in England – "100% renewable is possible" says Altechnica study.

Dr Derek Taylor, Altechnica and OU Open University Energy & Environment Research Unit

The Altechnica study on Renewable Energy potential in Uttlesford (commissioned by Uttlesford Futures) study shows that it would be potentially possible to ultimately obtain all of the household electricity, space & water heating needs and power personal cars from 100% renewable energy from within Uttlesford.

Uttlesford is the East of England District located in the North West corner of Essex that borders Cambridgeshire and Hertfordshire and includes Saffron Walden, Great Dunmow and Stansted Airport within its boundaries. – Prior to Uttlesford Futures commissioning the study, Uttlesford District had been reported as emitting the most CO2 per household in England.

This study showed that domestic heat provision, electricity and potentiall
