El Hierro July 2016 performance update

During July the hybrid wind-hydro Gorona del Viento (GdV) plant set a new record of 65.9% renewable energy delivered to the El Hierro grid, handily exceeding the previous record of 53.9% achieved in June. This was dominantly a result of a continuation of the sustained northerly winds that began in mid-June. Continue reading

El Hierro completes a year of full operation

At the end of June the Gorona del Viento (GdV) plant completed its first year of full operation, during which it supplied 34.6% of El Hierro’s electricity demand with renewable electricity at a cost probably exceeding €1.00/kWh while lowering the island’s CO2 emissions by approximately 12,000 tons at a cost of around €1,000/ton. This post summarizes these unexpectedly poor results, discusses the reasons for them and concludes that GdV, which was intended to show the world how fossil fuel generation can readily be replaced with intermittent renewables, can already be classified as a “failed project”.

El Hierro, March/April 2016 update:

The Gorona del Viento (GdV) plant on the Canary Island of El Hierro is a flagship project designed ultimately to provide the island with 100% renewable electricity and to demonstrate that hybrid wind/pumped hydro systems can be used to generate 100% renewable electricity in other parts of the world. GdV comprises a wind park with 11.5 MW capacity and a pumped hydro storage plant with 11.3MW capacity, installed at a total cost of €84 million. This is the fifth in a series of operational updates that began in September last year. Details on GdV plant layout, operation and capacities are given in the September update. Previous posts on GdV are accessible through the El Hierro Portal. Continue reading

More revelations on Venezuela’s “drought” and the Guri Dam

Just when I thought my recent post on the Venezuela drought was dead and buried a comment appeared. It was posted by Miguel Octavio, a physicist by training who lives in Miami but who visits Venezuela frequently, and it linked to a follow-up post on Miguel’s blog that contained a lot of local rainfall and stream flow data that weren’t available to me but which prove beyond any doubt that there is no drought at or around the El Guri dam.

EU 2020 Renewable Energy Targets: Part I

The progress being made in attaining the 2020 renewable energy (RE) targets is reviewed for 10 EU countries and for the EU as a whole using BP 2015 data. There are two main targets to be met 1) 20% of all primary energy from RE sources and 2) 10% of transport fuel from RE sources. The EU as a whole is projected to narrowly miss the 20% RE target by about 1%. The transport fuel target is less easy to estimate but will likely by missed by a substantial margin. Continue reading

EU to Introduce Two New Time Zones

Earlier today Mr Donald Trunk, EU Commissioner for Social Adjustments, launched an initiative that will see two new time zones introduced before the end of 2017. Mr Trunk explained that spreading electricity demand more evenly across the continent will help integrate the new electricity market and reduce peak demand. What better way to achieve integration than to divide the continent into 5 time zones? Continue reading

El Hierro Renewable Energy Project – End 2015 Performance Review and Summary

The Gorona del Viento (GdV) plant on the Canary Island of El Hierro is a flagship project designed ultimately to provide the island with 100% renewable electricity and to demonstrate that hybrid wind/pumped hydro systems can be used to generate 100% renewable electricity in other parts of the world.

The data accumulated since full operations began on June 27, 2015 are sufficient to show that the GdV plant as presently structured is not capable of supplying 100% of El Hierro’s electricity demand for 100% of the time.

Food, Population, Energy and Climate Change in MENA

According to the UN IPCC AR5 report, climate disasters have not increased in frequency. Food production has kept pace with population growth averting famine thanks mainly to fossil fuels not despite them. And evidence for climate change related drought and food shortages in MENA (Middle East North Africa), the subject of this post, is sparse to absent. Continue reading

Electricity and the Wealth of Nations

There’s no doubt that electricity is fundamental to GDP growth and that wealth in our modern society cannot be created without it, but a key question is; which comes first? Does the electricity create the wealth, or does the wealth create the electricity, or is the linkage between the two so close that it’s impossible to say? Continue reading

Wind Blowing Nowhere – Again

The central question lies in the wisdom of distributed power generation. Generating your own wind power down on the farm or solar power on your two bedroom semi’s roof may sound like a great back to nature green solution to electricity production. That is until the wind doesn’t blow and the sun doesn’t shine and your dependency is shifted to the owner of the 3000 mile long, 200 GW HVDC power line to Saudi Arabia. Is it not better to be dependent upon the 100 mile long, 1 GW power line to your local nuclear or gas fired power station? Continue reading

Waiting for Patricia

Here at latitude 20S in Mexico we get hurricanes. Normally they head off west into the Pacific without doing any damage, but late in the year they sometimes turn right and head inland. Hurricane Patricia is doing that right now. And Patricia isn’t just any old hurricane. According to weather.com it’s “the most powerful tropical cyclone ever measured in the Western Hemisphere”. Continue reading

El Hierro Renewable Energy Project – September 2015 Performance Review

After a year-long test period the Gorona del Viento (GdV) plant went into full operation on June 27, 2015. According to grid data published by the Red Eléctrica de España (REE) renewable energy from GdV has supplied 42% of the electricity sent to the El Hierro grid in the 96 days of operation since then (from June 27 through September 30) with the remaining 58% coming from diesel.

“Renewable”, “Sustainable” And The Brundtland Commission

The term “sustainable development” was coined and defined in Our Common Future, a report released by the UN World Commission on Environment and Development, more commonly known as the Brundtland Commission, in 1987. Continue reading

“The bottom of the market may still be ahead”

The title of this post, “The bottom of the market may still be ahead”, is the last line of the July IEA OMR summary. Those companies and investors hoping for an early end to this low price crisis may be disappointed. Global supply was up again in June by 550,000 bpd. Demand growth looks set to slow. Inventories are at record levels. And not surprisingly prices have once again yielded to the gravity of glut and have fallen below $60 / bbl. To add insult to injury US oil rig count has risen these last two weeks and UK North Sea oil production looks set to rise in the years ahead. Continue reading

The DECC Pathways Calculator – A False Prophet

In a comment on the recent power-to-methane post I made the following observation:

“It would be an interesting exercise to take a high-renewables-penetration DECC scenario that meets UK emissions targets, convert it to hourly generation by factoring actual Gridwatch generation and compare it to demand for, say, 2013 or 2014. I’d be willing to bet the UK would be freezing in the dark for much of the time during the winter.”

Well, the interesting exercise is now complete and this post documents the results. Continue reading

Averaging Temperature Averages

I sent a link to my recent post The Hunt For Global Warming: Southern Hemisphere Summary to Professor Richard Muller at Berkeley drawing attention to the gulf between Berkeley Earth Surface Temperature (BEST) for southern hemisphere land and the compilations produced by Roger Andrews and I (Figure 1) in the hope that he or his group may help us to understand where the discrepancies may lie. He passed this on to Steven Mosher to respond and we exchanged several emails. Continue reading

The Hunt For Global Warming: Southern Hemisphere Summary

In recent months I’ve had a series of posts looking at the temperature histories of a number of land areas in the Southern Hemisphere [1, 2, 3, 4, 5]. This was in response to a post by Roger Andrews where he presented an analysis of about 300 climate stations from the Southern Hemisphere that, when combined, showed substantially less warming than the reconstructions presented by various groups (BEST, GISS, HadCRUT) [6]. I found this to be both intriguing and important and wanted to see if I could replicate Roger’s result. Continue reading

Homogenizing the World

A few weeks ago I put up a post on how the homogeneity adjustments applied by GISS to raw surface temperature records increase warming at the hemispheric and global scale. In this post I extend the review to include the homogeneity adjustments applied by NCDC, CRU and BEST and re-evaluate GISS using a series which is more relevant than the “meteorological station only” series I used last time.
