Renewables and the Grid Conference – May 13-14, 2009 | Almas Temple Club, Washington, DC
Posted by: | CommentsPart Two of an Interconnected Conference with:
National Energy Policy
Transmission holds the key to meeting renewable energy goals nationwide. It is projected that nearly all easily accessible wind sites will be exhausted within two to four years, and both utility-scale solar and geothermal are likewise transmission constrained. Hundreds of billions of dollars of investment in transmission megaprojects, smart grid technology and power storage are needed to support the coming wave of renewable development. What national policy changes will be implemented regarding transmission siting, cost allocation, smart grid commercialization and energy storage? What impacts are state and local initiatives like CREZ, WREZ and RETI having on the development of transmission to serve renewables? Will queuing issues for renewable projects be solved?
The Renewables and the Grid Conference will bring together utilities, regulators, ISOs and renewable energy developers to discuss how to overcome regulatory and operational challenges to facilitate the delivery of renewable energy. They will explore the potential changes to national transmission siting and cost allocation policies; the expansion of incentives for smart grid commercialization and power storage; and the effectiveness of state and local initiatives to drive the construction of transmission to bring renewable energy to load centers. Finally, they will examine the status of transmission megaprojects proposed to serve renewable energy as well as pilot energy storage projects.
The conference will be closely tied to another event, The National Energy Policy Conference, which will unite utilities, independent power producers, regulators, renewable energy companies and other stakeholders to discuss the latest national energy policy developments.

Time is running out for UK flagship wind project London Array
Posted by: | CommentsGregory Barker, the Shadow minister for climate change writing in the Sunday Times, 1st Feb, “Brown has a Power Failure” points out that unless a decision is made soon to go ahead with the London Array in the Thames Estuary, then National Grid will miss the slot allocated to upgrade the Grid in time.
Apparently National Grid will soon be devoting all their efforts to sorting out the supplies for the Olympics in 2012, and after that NG will be fully booked on other projects.
Barker says that the decision to invest or not, must be made in the next few months, or possible weeks. With the fall in the pound, and most of the stuff priced in Euros, the economics have gone against the scheme. Meantime the government report into how to better support Renewables won’t be published till next April.
Another example of the folly of assuming that markets can deliver the kind of energy infrastructure we will need in years to come.
It clearly requires some sort of central planning from independent engineers and economists who know what they are talking about, and not left to the whims and interests of the large energy players (who are off course all foreign owned in the main) and generalist (and influenceable by the unspoken thought of lucrative non-exec directorships in energy companies on retirement) civil servants. We could call the results of such planning an Energy Policy. The suggested mechanism to create such a Policy is here.
This also shows how daft it would be, to assume that we can get on building as many renewables as possible and worry about the European Super Grid later – since the Super grid will take at least a decade or two, you have to start planning and building it now, on the assumption that the renewables will come along later to populate it, since these typically only take around 3 years.

Where Does The Wind Come From – And How Much Is There?
Posted by: | Comments
Brian Hurley - Wind Site Evaluation Ltd
Introduction: The source of the wind is the sun. The winds come from the suns energy falling on the earth’s surface. Due to the orientation of the earth’s surface to the sun’s rays near the equator the rays strike the surface at more optimum angles. The effect is that the air near the surface in tropical regions is heated more than the air near the surface of the polar regions. This leads to convection currents in the atmosphere, ie the movement of air due to changes in its density and pressure. This air movement is the principal cause of the winds.
Global Scale Circulation of the Atmosphere – A Simple Model of Global Circulation
We can gain an understanding of how global (or planetary) circulation works by developing two simplified graphical models of processes that produce this system. The first model will be founded on the following simplifying assumptions:
- The Earth is not rotating in space.
- The Earth’s surface is composed of similar materials.
- The global reception of solar insolation and outgoing longwave radiation cause a temperature gradient of hotter air at the equator and colder air at the poles.
Based on these assumptions, air circulation on the Earth should approximate the patterns shown on Read More→

European Super Grid – press release

Expert unveils plan for a European-wide renewable electricity solution
At the fourth Claverton Energy conference, hosted by Wessex Water, Bath, international energy expert Dr Czisch outlined his strategy for a European-wide super grid that would supply all of Europe with entirely renewable electricity. Speaking at the conference Dr Czisch of Kassel University, Germany, also said the move to a renewable electricity system could cost the UK consumer the same as what is currently being paid, and, if there is the political will, he added that it could in theory be achieved in decades.
Dr Czisch, who has conducted research of world weather patterns and European electricity consumption on an hour by hour, day to day basis, says Europe could ensure its energy security, slash its CO2 emissions and have a sustainable, renewable electricity supply by employing a network of wind turbines that stretch across the continent from Siberia to North Africa, where the wind is most constant. This would be supported by biomass, coupled with an extended transmission system and existing hydropower plants providing storage capacity. In Dr Czich’s Czisch’s system wind would account for 70% of the electricity mix. Biomass and hydro would provide storage and back up and the biggest part of the remaining electricity production. All of this is the result of a mathematical optimisation that allows for maximum objectivity in searching for the lowest cost renewable electricity supply for Europe and its neighbourhood. Read More→

UK ENERGY SYSTEM COULD SUFFER SAME FATE AS BANKS, EXPERTS WARN
Posted by: | CommentsIndependent energy experts also set to announce how an entirely renewable electricity supply for Europe is possible and affordable
Representatives of an independent group of over 250 international energy and financial experts are meeting this week to reveal how the UK, Europe and other continents can run on renewable electricity for a similar price to that currently paid for fossil-based electricity. The Claverton Energy Research Group is also warning on the eve of its conference, which runs in Bath from 24-26 Oct, that current world governments’ energy policies are inadequate to meet growing global energy demands, and says serious action needs to be taken now before fossil fuels become in increasingly short supply, arguing the recent oil price spike is merely a foretaste of what could happen in the not too distant future. The group also says that as the North Sea gas and oil output declines and being at the extremity of the gas supply system places the UK particularly at risk and warns there could be energy shortages by as early as 2015 if the current situation continues and planning is neglected. The group says that if the energy infrastructure is left to develop in response to market forces, which is the government’s preferred strategy, it will create a similar crisis to that unfolding in the banking sector.
Conference spokesperson, Dave Andrews, whose 1983 book, IRG Solution, predicted the coming environmental and fuel catastrophe and detailed a method for a coordinated effort from experts to develop workable policies, says: “We have seen recently what a lightly regulated market without proper, well thought-out policies has done for banking and finance, and our evidence indicates the UK energy supply infrastructure, if left to regulate itself, is heading towards a similar crunch.”
As an example, Andrews cites Denmark, where experts working with Danish government decide energy policy, and 90% of the heat created in the process of making electricity in Denmark is used to heat homes and buildings. It is an extremely efficient process with little waste. In the UK, on the other hand, when energy companies make electricity they are allowed to waste the by-product heat in cooling towers (the amount of heat wasted annually in this process is similar to the amount of energy taken out of the North Sea each year) and then energy companies benefit by selling more fossil fuels to consumers to heat their houses, leading to unnecessary fuel imports and rapid depletion of the North Sea.
