I think this open letter from Jeremy Leggett of Solar Century to Cameron puts the current situation into clear context: 4 November 2011 The Right Honourable David Cameron MP Dear Prime Minister You will recall that five years ago you chose to host your first Shadow Environment team ‘meet the media’ event at Solarcentury. I […]Read More

Mark Jacobson and Mark Delucchi recently published two papers in Energy Policy expanding upon our article on 100% wind, water, and solar power for the world, published in Scientific American in November 2009. I am attaching corrected in-press proofs of the articles. Mark and I continue to work on various aspects of this, so we […]Read More
Need a regular up to date source of hard info on renewable energy? Renew is a 36 page newsletter on renewable energy developments and policy which has been produced by Open University Professor Dave Elliott without a break bi-monthly since 1979. It’s widely seen as a reliable and up to date source of information, news […]Read More
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
In general it can be seen that there is not a lot to choose between the cost of wind energy, and coal, gas or nuclear. PV and CSP are considerablymore expensive however.Read More
Subject: Renewable Community Energy – request from George Hay in the US.

This article describes a novel concept using existing technology to very quickly a) control the desertification and sand drifts b) enable the establishment of plant species c) the construction of wind farms or CSP connected to Europe by either a lengthy HVDC transmission system, or the local production of ammonia which can readily be transported to eg Europe / USA and easily used as a vehicle fuel d) the construction of a vast area of seawater greenhouses using sea water pumped thousands of miles to be desalinated by solar energy to allow the production of food and or energy crops. (Contrary to what some ill-informed people claim this does not use a huge amount of energy compared to other national uses) e) unlocks the massive potential for carbon sequestration via organic matter in soilRead More
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 […]Read More
