The Sun is Our Only Truly Renewable Energy Source
Wind and wave energies are not renewable after all

The Variability of Wind Power
Paul-Frederik Bach


"If we want an economically efficient electricity system it is essential that full data relevant to all the costs imposed on customers by generators should be in the public domain. At present this is not the case. For example, actual metered generation data is costly, difficult, or impossible to obtain. This is not in the public interest."
Dr John Constable,

The occasion of these remarks was the publication of a collection of papers by the leading European engineer, Paul-Frederik Bach, formerly Planning Director for the Danish grid, and the launch of REF's latest Renewable Energy Data files, including a new searchable online database giving free information, including performance data, for all 5,400 renewable electricity generators operating under the Renewables Obligation subsidy www.ref.org.uk/roc-generators

Speaking at the event Professor Michael Laughton, FREng, who has contributed a preface to Mr Bach's book, said: "Paul-Frederik Bach's work uses large bodies of publicly available Danish and German data to analyse and address wind integration problems. At present we could not attempt to replicate this work in the UK as the data simply isn't available. That has to change."

Mr Bach said: "Planning for future electricity systems requires data transparency. The UK situation is frustrating, and increases the risk of future difficulties and costs to the consumer."

Paul-Frederik Bach


Paul-Frederik Bach worked with grid and generation planning at ELSAM the west Danish power station operator, until 1997, and then as Planning Director at Eltra, the Transmission System Operation, with special responsibility for integrating wind generation. He is one of Europe's leading grid engineers, and is still active in advising the Danish government on the direction of its policy.

Professor Michael Arthur Laughton is Emeritus Professor of Electrical Engineering at Queen Mary, University of London.

As a Fellow of the Royal Academy of Engineering, Laughton is currently the UK representative on the Energy Committee of the European Council of Applied Sciences and Engineering (EuroCASE), a member of the energy and environment policy advisory groups of the Royal Academy of Engineering, the Royal Society and the Institution of Electrical Engineers, as well as the Power Industry Division Board of the Institution of Mechanical Engineers.He has acted as Specialist Adviser to UK Parliamentary Committees in both upper and lower Houses on alternative and renewable energy technologies and on energy efficiency.

The Economics of Renewable Energy - Economic Affairs Committee 

Memorandum by Professor Michael Laughton
1.  INTRODUCTION

Energy from renewable sources would result in significant increases to the present electricity supply cost levels. This submission seeks to explain and to quantify factors underlying these circumstances from a power systems engineering perspective. The feasible cost limits for consumers are not addressed. Instead the focus here is on the costs arising from maintaining power supply security, ie "Keeping the lights on".
