David Millborrow is a Claverton participant…. Thanks to Hugh Sharman for forwarding this piece. This article from David Millborrow seems to pretty much demolish this article.. .. http://tx1.fcomet.com/~claverto/cms/download/316/ …………………………………. Quote ” Today, the UK is committed to European Union targets to deliver 35 per cent of electricity from renewables by 2020. Starting from a base of […]

Part 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 […]
Read MoreHow Much Wind Energy is there? – Brian Hurley – Wind Site Evaluation Ltd.
Introduction
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

BWEA (British Wind Energy Association) will be launching its first Budget submission, ahead of the Budget speech on April 24th. Following a consultation process led by the BWEA, the UK wind industry is putting forward proposals to the Treasury on how to maintain the momentum in the wind sector, on and offshore, during the […]
Read MoreToronto gets feed in tarrifs – we don't – we wonder why.
Quote “Renewable energy in Ontario got a massive boost Thursday with the proposal of a fixed-price plan that, by June, could see the province paying out generous premiums to large and small generators of green power. The premiums – called advanced feed-in tariffs – are what the government guarantees to pay over the life a […]

Interesting item claims scientists have developed “affordable”, rapid-charge / discharge modified lithium-ion batteries. This improvement might make a significant difference to the prospects for practical EVs / PHEVs, by extension to G2V for smoothing wind energy outputs. http://news.bbc.co.uk/1/hi/sci/tech/7938001.stm
