Papers in Energy Policy from Mark Delucchi and Mark Jacobson, Stanford / California University USA – 100% renewable energy at reasonable prices and timescales

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 […]

Has Professor MacKay FRS, Chief Scientific Advisor to DECC, underestimated Britain's potential for Renewable Energy?

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.

Notes on Spanish Solar Energy Plants (CSP)

At this moment, Spain has about 150 MW of thermo electric plants
connected to the grid; some 750 MW are under construction and some 14 GW
of these types of plants have requested license and have established the
required bonds by the Spanish government. There are basically three
types of plants:

ADRECS – How To Rapidly Convert The Central Deserts Of China To Agricultural Regions Producing Huge Amounts Of Renewable Energy For Europe

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 soil
