    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

    Dear SE 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

Biofuels and Food Security should be a very important aspect of this group - 152 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? - 134 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 - 240 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 - 157 views

General
  • Hans De Keulenaer
     
    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.

    Dear Group users:

    I've activated the forum, which allows posting in 7 categories:
    - renewable energy
    - energy efficiency, including conservation
    - clean carbon: cogeneration, carbon sequestration, efficient combustion, ...
    - technology
    - environment, including climate
    - policy & finance
    - projects & programmes

    We look forward to your contribution.

    Regards,

Cross Post of stories - 78 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.
