Assessment of European Pumped Hydropower Storage Potential (This is posted on behalf of the JRC – Joint Research Centre) Dear colleagues We have finished our modelling of the potential for pumped hydropower storage in 21 European countries (see list below). This potential is the result of adding up individual results from 3500 sites (topology A […]Read More
Roger, My own analysis has also shown that there is insufficient value in the difference between peak and off peak electricity prices to make energy storage economic. However, this may not be the only revenue stream for an energy storage system. Mechanisms that may provide greater return are as you say, within islanded communities (where […]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
The Conference on Independent Power Generation will be held at the NEC Birmingham, 8th – 10th June 2010. IP&EE – Independent Power & Energy Europe – is the essential biannual event for the Independent European Energy Sector. The Show provides an ideal platform for players in the energy industry to showcase the latest cutting-edge technology […]Read More
Hydro Capacity in the EU-15 and Norway 22 days the energy storage capacity of hydro across Western Europe, (the EU15 countries plus Norway and Iceland), expressed in terms of average daily electricity demand 177 TWh the storage capacity, put another way. That’s the same as 0.604 quads, 22MTCe, 15 MTOe, 152Pcal, 637PJ, or 465kWh per person across […]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
Plans to link Europe to what would be the world’s biggest hydroelectric dam project in the volatile Democratic Republic of Congo have sparked fierce controversy.
The Grand Inga dam, which has received initial support from the World Bqank would cost $80bn (£48bn). At 40,000MW, it has more than twice the generation capacity of the giant Three Gorges dam in China and would be equivalent to the entire generation capacity of South Africa.
Grand Inga will involve transmission cables linking South Africa and countries in west Africa including Nigeria. A cable would also run through the Sahara to Egypt.Read More
An example of intermittent power – 25 GW lost in a millisecond Source: Reuters : By Ilya Naymushin CHERYOMUSHKI, Russia, Aug 17 (Reuters) – Ten people were killed on Monday and up to 72 were missing after a turbine room flooded at Russia’s largest hydro-power station, forcing steel and aluminium plants in Siberia to turn to […]Read More
