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 […]
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 […]
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 […]
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% […]
Blowout Week 172
Blowout Week 172 In this week’s Blowout we return to Brexit and its impacts. It is now reported that following Brexit the UK will “scale down its concern over climate change” and scrap the EU’s 15%-of-total-energy-from-renewables-by-2020 target. Can outright repeal of the 2008 Climate Change Act be far behind? Telegraph: Britain preparing to scrap EU […]
The dream of 100% renewables assessed by Heard et al
The dream of 100% renewables assessed by Heard et al Posted on April 12, 2017 by Before the world can transition from fossil fuels to 100% renewables it must come up with a transition plan that has some realistic chance of working. So far Energy Matters has evaluated a few such plans, including ADEME and […]
Blowout Week 167
Blowout Week 167 There are some people you just can’t hold down. One of them is Elon Musk, who has offered to solve South Australia’s grid problems within a hundred days by installing Tesla utility-scale batteries and not to send a bill if the fix doesn’t work, thereby displaying true confidence in the future of […]
The causes of the recent decrease in US greenhouse gas emissions
The causes of the recent decrease in US greenhouse gas emissions Since their peak in 2007 GHG emissions in the USA have decreased more in absolute terms than in any other country. The results of this review suggest that approximately 40% of this decrease was caused by the replacement of coal with gas in generating […]
Emissions reductions and world energy demand growth
Emissions reductions and world energy demand growth A major obstacle to cutting global CO2 emissions is growth in world energy demand. In this post I examine world energy growth projections from a number of different sources and compare them with the growth trends that will be necessary to meet emissions reductions goals. It goes without saying […]
Blackout California
Blackout California The shutdown of the leaking Aliso Canyon underground gas storage facility has caused a loss of about 70bcf of stored gas that Southern California utilities have historically counted on to see them through the hot, high-demand summer months. The California Independent Service Operator (CAISO), which manages the California grid, estimates that as a […]
Blowout Week 123
Blowout Week 123 A few careless campers who forgot to extinguish their campfire, or maybe a few kids playing with matches, or a cigarette, or an arsonist, a piece of glass, whatever, have in the last few days done more to bring the global oil market back into balance than OPEC and the rest of […]
More revelations on Venezuela’s “drought” and the Guri Dam
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 […]
