UK offshore wind capacity factors – a semi-statistical analysis
UK offshore wind capacity factors – a semi-statistical analysis The average capacity factor at 28 operating UK offshore wind farms is 33.6% (most recent 12-month average) and 34.5% (lifetime), increasing to 36.1% and 37.5% when four demonstration projects are discarded. There is a dependence of capacity factor on age, with older farms showing capacity factors […]
Oil Production Vital Statistics September 2017
Oil Production Vital Statistics September 2017 On around June 28th the price of WTI and Brent once again began to diverge and the spread now stands at over $7. The WTI – Brent spread was a feature of the high oil price era and its reappearance could be a bullish signal for the oil price. […]
Blowout Week 196
Blowout Week 196 The big news in the Energy Patch this week is the Kurdish independence vote, which threatens to disrupt the global oil market and could lead to civil war in Iraq. We follow up with the usual dose of stories from around the world: surging global demand for diesel; the Aramco IPO; US […]
Apple, Google, and how not to go 100% renewable
Apple, Google, and how not to go 100% renewable Earlier this year I described how the Dutch Railwayswere using “alternative logic” to claim that their trains were running on 100% wind power while in reality they were running about 90% on coal and gas-fired electricity from the Dutch grid. But Nederlandse Spoorwegen aren’t the only […]
The Real Cost of Offshore Wind
The Real Cost of Offshore Wind A couple of weeks ago (I think September 11) I was watching BBC news mid morning, following the Hurricane Irma story and I happened to catch an editorial on the recent CfD auction where the lowest bids for offshore wind came in at £57.50 / MWh, well below the […]
Blowout Week 195
Blowout Week 195 It’s official – climate models are overheating and global warming may not be so bad after all. So say two authors of the recent Nature Geoscience study featured in this week’s Blowout. Nature, however, puts a different spin on this “good news” in the next article. We follow up with our customary […]
The real strike price of offshore wind
The real strike price of offshore wind Hinkley still scores on reliability and low carbon ….. but the extent to which its costs are obscene is now plainer than ever. In Monday’s capacity auction, two big offshore wind farms came in at £57.50 per megawatt hour and a third at £74.75. These “strike prices” ….. […]
Blowout Week 194
Blowout Week 194 Britain, France, Norway and India have already announced their intention to ban fossil-fuel-powered vehicles in favor of EVs and a number of other countries are considering it, and in this week’s Blowout we feature China, which is about to join the club. To follow we have the usual mix of energy-related stories […]
Adjusting Measurements to Match the Models – Part 3: Lower Troposphere Satellite Temperatures
Adjusting Measurements to Match the Models – Part 3: Lower Troposphere Satellite Temperatures Except for small gaps over the poles the satellite temperature series are the only truly global temperature series we have; their defect is that they do not begin until 1979. Published series are constructed using raw records from different satellites that require […]
Atlantic Hurricane Trends and Mortality
Atlantic Hurricane Trends and Mortality Since 1851 there has been on average 5.4±2.5 (1SD) Atlantic Hurricanes per annum. There is a clear trend of rising frequency from 4.4 Hurricanes per annum in 1851 to 6.3 per annum today, that is a rate of increase of 1.2 hurricanes per annum per century. Mortality from Hurricanes has […]
Rising Seas Swamp Scotland
Rising Seas Swamp Scotland Since April the sea around Scotland has risen by an average of 43 centimeters, reports the Sunday Herald, a rate of rise that far exceeds even the worst-case projections of climate scientists. Caught by surprise, the government is preparing emergency evacuation plans for residents of coastal areas and other low-lying areas […]
The Terrifying Risk of Climate Change in Scotland
The Terrifying Risk of Climate Change in Scotland “Major parts of Scotland’s vital infrastructure are under threat from coastal erosion and flooding, according to the latest government assessments of the dangers of climate change. Thousands of homes and businesses and long stretches of roads and railway lines are also at risk. So are power stations, […]
An initial look at the Australian electricity grid data
An initial look at the Australian electricity grid data An Energy Matters contributor recently started to record electricity grid generation data from a published Australian source, giving us the opportunity to begin evaluating the performance of the Australian grid. This post reviews the limited amount of data (19.5 days) presently available. The reviews show that […]
UK Flooding Events and Fake Science
UK Flooding Events and Fake Science Blöschl et al (2017, ref 1) published a paper in Sciencethat purports to show flooding in S England occurs every year but only ever in January and that flooding is disconnected in time from extreme rainfall events via water storage in soils. The changing pattern with time is ascribed […]
Quantifying the causes of the recent decrease in US CO2 emissions
Quantifying the causes of the recent decrease in US CO2 emissions Between 2007 and 2015 total annual US CO2 emissions decreased by 740 million tons (12%). An updated analysis shows that 35% of this decrease was caused by natural gas replacing coal in electricity generation, 30% by lower fuel consumption in the transportation sector, 28% […]
