Go straight to the web form. If you want to know how to design your building you to need to know what the local weather is like. If you want to understand how your building is performing you need to know what weather it was coping with. If you want to install renewable energy – [...]
The range of wind EROEI I found during my literature review for the table on page 61 of the Offshore Valuation is staggeringly large. Much larger in fact than any of the other technologies included. It demands consideration of why this might be. There are two (or three) categories of answer to this question. Firstly [...]
See also The EROEI of electricity generation. In a future with the huge increase in variable renewables predicted in such places as zerocarbonbritain, the Offshore Valuation, and Sustainable Energy Without the Hot Air, it will be necessary to find ways of matching up supply and demand. Currently this is done by trimming the output of [...]
Firstly this isn’t (entirely) a post about EROEI. The EROEI of wind is generally very high so the embodied emissions of building wind turbines in unlikely to lead to more emissions than they avoid. No, this worrying suggestion is inspired by a recent study by Chien Wang and Ronald Prinn at MIT. They used a [...]
As you may have read here before, wind energy can be captured very efficiently by large, offshore wind turbines. In fact, the larger the better. Despite this, there is still a place for smaller wind turbines – just so long as it’s the right place. So what is the right place to site a small [...]
See also The EROEI of energy balancing. I’ve been spending a lot of time thinking about EROEI (energy return on energy investment) lately since Tim Helweg-Larsen at PIRC asked me for help with a report. The report, “The Offshore Valuation” was produced by the Offshore Valuation Group chaired by PIRC and it looks at the [...]
