Late last year, Tom Blees, I and a few other people from the International Award Committee of the Global Energy Prize answered reader’s energy questions on The Guardian’s Facebook page. The questions and answers were reproduced on BNC here. Now we’re at it again, this time for the website Eco-Business.com (tagline: Asia Pacific’s sustainable business community). My section [...]

The Christmas to New Year period is traditionally ‘hibernation mode’ for blogs, when page views and comment counts plummet (my hits have dropped about 70% compared to early December!). I suppose this is a time when people find better things to do than sit in front of a computer screen (family time, good food, beach/snow [...]

The Guardian newspaper’s Environment Facebook page recently put the following to their readers: Ask the Global Energy Prize‘s expert panel your toughest energy questions and they’ll be back here on Friday with their answers. What should power our cities, homes and industry in the future — renewable energy, nuclear power, or fossil fuels? How significant [...]

Guest Post by Jani-Petri Martikainen. Jani-Petri is a theoretical physicist doing fundamental research in the field of ultracold quantum gases. Most of his current research activities are computational and involve bosonic or fermionic atoms in optical lattices. He has a lively interest on environmental, climate, and energy issues. He runs the blog PassiiviIdentiteetti, which is mostly written in Finnish. [...]

Debate over large-scale energy storage is a regular theme in the comments on this blog. The post is intended to be a place to centralise this discussion. Some questions that might be considered in the comment thread: 1. What is the cost (per Watt hour, kWh, MWh, GWh — how does this cost scale up, [...]

How can we compare the cost, performance and value-for-money of alternative large-scale clean energy projects? Actually, it’s pretty tough to try and avoid apples-and-oranges comparisons. Still, some adjustments can be made, such as for capacity factor, to partially levelise comparisons. Below is a simplified comparison of four recent real-world projects. All can be considered first-of-a-kind [...]

In a recent issue of Dissent magazine, a regular commenter here on Brave New Climate, industrial engineer Graham Palmer, engaged in a debate with Mark Diesendorf on energy futures. Unfortunately, this exchange of prose is not available online, although Graham did send me a scanned version (because of potential copyright issues, I won’t post it here). The [...]

People seem to like to infer motives. (Perhaps it’s an inherent evolutionary trait, allowing anticipation of your prey’s or predator’s next move?) I find that a lot of people get me wrong about my position on energy and sustainability — often deliberately so, I suspect. So here’s a post to clarify my position, and allow [...]

In the previous TCASE post, I considered how various low-carbon energy technologies meet the following criteria: commercial readiness, scalability, dispatchability, fuel constraints, load access, storage requirements, capacity factor and emissions intensity. Here I consider the next issue: cost of deployment, based on expert consensus. The primary data again come from the work I had published in 2011 [...]

The problem of replacing our dependence on fossil fuels is complex. In Thinking Critically About Sustainable Energy (TCASE) #12, a checklist was provided to allow assessment of energy transition plans. The sort of questions listed in TCASE 12 are critical for evaluating the feasibility of future scenarios, like the ones from the recent IPCC report [...]

The following is a detailed guest post by Dr Ted Trainer, University of NSW (http://ssis.arts.unsw.edu.au/tsw/). In it, he provides the most detailed critique I’ve yet seen of the recent IPCC renewable energy scenarios report. Now, I don’t agree with everything Ted says — in particular the conclusion that the only feasible alternative to large-scale renewables is “The [...]

Regular readers of BNC would know that I’m hardly the only climate change researcher to recommend serious deployment of nuclear energy to displace fossil fuels. (Although I’m often portrayed as an isolated [and presumably therefore ignorant?] voice on this point). One very prominent example of a colleague in arms is my fellow SCGI member, Dr [...]

Most readers of BNC know the story — after the Fukushima nuclear crisis, the German government announced that Germany would phase out all of its nuclear generation capacity by 2022. In almost the same period, Germany also aims to cut its national greenhouse gas emissions to 40% of 1990 levels (by 2020). Their emissions have [...]

A common lament of those analysts wishing to get to grips with the real-world performance of solar thermal power plants has been, well… an absence of data. Trainer noted, in ‘Solar Thermal Questions‘: It would be great to get some actual data on their year round performance. I have found it fiendishly difficult to get [...]

Climate change and sustainability of the global human enterprise are two of the most critical issues of the 21st Century. If we are to tackle these problems effectively, we need to make prudent, evidence-based choices about energy. This is the story told by this short (2 min, 35 sec) animated video: ————————- Please share the [...]
