It took me 4 years to respond, but that should not stop me. Energy touches on many aspects of society. We have for example the energy-water nexus which received a lot of attention over the past years. Food is basically energy, and the food sector is a big energy users. Oxygen, hydrogen, methanol, ... are produced with energy and can be combusted ...
I wonder whether the 21st century will be about the energy & data. Some of the major new industries emerging are data driven. Warfare becomes cyber-warfare. On the other hand, climate change is the defining challenge for our generation, and it mainly relates to energy.
After 4 years, this post merits more than a few random thoughts, but let's start here.

a bit of discipline on tagging - 120 views

Dear energy group members:
It's starting to take more time to maintain the tag could of this group, and increasingly, synonym or rogue tags are slipping in. So therefore, you help please!
- tag with distinctive keywords
- tags in small letters (canada and not Canada)
- tags in plural where applicable (e.g. photovoltaics and not photovoltaic)
Thanks,
Hans -
As we're developing this library, a few more points.
Tags can be used to group items in the library. It allows to build lists on countries, technologies, ... This however only works if applied consistently.
For location-specific bookmarks, use the country as a tag (e.g. egypt, canada, ...). Avoid using the municipality or prefecture as a tag, as we're unlikely to accumulate more then few bookmarks for such specific tags.
Next to location, add technology-specific tags (e.g. photovoltaics, appliances, efficiency, ...) or policy related (feed-in, incentives, targets, ...).
For major OEMs (bmw, abb, ...), it's OK to add them as a tag. The same goes for major project (desertec, masdar, ...). -
As I'm cleaning up tags, a few points in addition:
- avoid meaningless tags. E.g. energy, as this is an energy group. Or green - what does that mean?
- tags in plural please. We've started this way and should continue.
- no capitals, even for country names.
- check the tag dictionary for this group once in a while to find the proper tag. I'll moderate but your help is welcome.
- use many tags, as long as they are relevant and consistent with the tag dictionary for this group. But do not just paste titles or whole paragraphs in the tag box.
- tags should be in English, even for bookmarks in other languages.
- not "energy efficiency", "energy security", "energy scavenging" etc but efficiency, security, scavenging, etc

This group is now in its 5th year, and has meanwhile accumulated over 200 members, 3000 bookmarks and almost 15,000 visits.
We're probably not using the social features of the group to its fullest extent (commenting, like, posting topics). So to make you aware of them:
1) In addition to bookmarks, you can post topics to a group, i.e. short articles with your comment or question. See the Post - Topic button just below the group header for this.
2) Both topics and bookmarks can be voted up by the 'like' button.
3) You can comment on topics and bookmarks. Your comments will just be added to the annotations already made on bookmarks.
Hope the group is meeting your expectations. We've been working to keep it spam-free. Occasionally, I've had to delete a couple of off-topic posts, or remove a user. But by and large, we're developing in a diverse library on sustainable energy.
A special thanks to Phil, The Energy Net, Glycon, Jeff and a few others for their ongoing contributions.
Best regards,
Hans -
An additional comment on these social features: liking or commenting on an older item, will bring it up on top again in the 'most recent' queue, which lists items that have been either added or updated in reverse chronological order. Another very nice feature in the diigo design!
What to post in this group - 2 views
-
This bookmarking group aims to categorise the world's knowledge on sustainable energy. Resources that give fact-based information on the subject are welcome.
We're interested in projects, technologies, programs and policies.
The energy system is in transition. We look for information that pushes the boundary, i.e. new technologies, projects or policies that are the first or the biggest in the world or in a region. On the other hand, we're not looking for '13 in a dozen' type of projects.
Thank you for your consideration.
happy new year, best wishes and this group in 2009 - 56 views

Dear Colleagues:
Happy new year to you all. We're now running since 18 months (75 weeks), and have accumulated over 2000 bookmarks and 80 members. That about 30 new bookmarks per week.
For the coming year, I think we need to work on the following:
- better organisation of this knowledge base through consistent and quality tagging
- adding value through rating and commenting
I'd love to hear from you where you'd like to take this group in 2009.
Best wishes,
Hans

I'll check member requests more carefully. New members need to either submit an expression of interest, or demonstrate an interest in energy issues through their account profile.
We'll endeavour to keep this group spam free and high quality.
Regards,
Hans

Biofuels and Food Security should be a very important aspect of this group - 154 views

Thanks for your posts, and for this comment. There appears to be some link between bioenergy development and food prices/shortages, though the 3 links you posted demonstrate already the complexity of the issue.
Personally, I think that bioenergy, and especially biofuel is largely a dead-end route. It's currently a cure which is marginally better than the disease. The current mainstream for transport appears to be electric and plug-in hybrids, though further development on batteries is needed.
I may be very wrong, if either of following technologies develops to supply bioenergy on a massive scale:
- cellulosic ethanol
- harvesting the energy from algae farms.
If you'd have to bet between relatively marginal development in battery technology, or producing millions of tons of oil equivalent from algae or cellulose, where would you put your money?
Superconductor market set for explosive growth? - 136 views
-
I just bookmarked superconductors.org, which appears to be one of the better information sources on superconductivity (though I've not gone in depth). At least, it gives a balanced view, avoids extravagant claims such as that we're going to convert the millions of km of cables and lines to superconductors, while still painting a very bright future for the sector. It appears that the sector may experience explosive growth in the coming decades, and a lot of that is to come from energy applications.
I would appreciate any market figures and forecasts for this technology.
A few things you can do in Diigo - 248 views
-
Just to alert you to a few things that are possible, and could help users of this group:
- giving bookmarks a thumbs up. As we're a group of 30-something, with diverse interests, your vote counts. 2-3 members thumbing something up is significant.
- comment on bookmarks: you can add your comments and annotations to existing bookmarks, thereby enriching the library.
Thanks for your consideration. -
Just used the 'invite to a group' feature for the first time. You can go to some of your diigo friends, and invite them to this group ;-}. It works like a charm.
Tagging & annotation - 159 views
-
When posting to this group, please tag carefully, and where possible, annotate your bookmark with highlights and comments. Only these bookmarks add value - quality rather than quantity.
Regarding tagging, we spend a lot of time keeping the tag cloud consistent. I've activated the feature to have group tag suggestions. Please bear in mind the following:
- using only lowercase: so germany rather than Germany
- use plural forms where both plural or singular could apply: e.g. cars, batteries, photovoltaics
- use specific tags. Avoid 'energy', 'on', 'of', ... (these are actual tags encountered)
Thanks for your consideration. -
"energy news" is quite OK. Feel free to use it. Thanks for checking first.

Cross Post of stories - 79 views
-
Sorry for a bit late-ish reply. On this group, we do not mind cross-posting, but we do strive to be selective. I.e. quality rather than quantity. So before posting, please check whether the story's facts stack up, or whether the project is original, or the idea novel.
In other words, we try to avoid PR-type of stories of yet another corporation buying a few carbon credits, yet another municipality jumping on the renewables bandwagon, or yet another harebrained scheme that only exists on a blog.
Another perspective - we like projects, ideas, technologies that push boundaries.

The new group description in turn reflects a need to address the energy transition's challenges while capitalising on its opportunities.
I hope this makes sense. Comments welcome.
