My review of the NREL Western Wind and Solar Integration Study
The NREL/GE Energy WWSIS study appears to be built on several questionable assumptions, each allowing the modeled system (of up to 30% wind/5% solar in the West Connect within the great Western Interconnect) to withstand the inherent difficulties of large scale renewable integration. The primary issue, consistent with my dissertation research, is that the authors assume that we can afford to massively overbuild the capacity of the system, adding the large percentages of renewable generation on top of newly built and existing plants. This allows one to be able to ignore the hourly or sub-hourly periods with extremely low output from renewables, as well as the days or weeks at a time during the summer when wind production is well below yearly average output levels. An ample reserve is at the ready to step in when renewables perform poorly. Secondly and equally important, the authors assume that coal plants, which have traditionally run in a base load capacity, will be able to be operated very flexibly – on par with combined cycle gas plants.
Green Poetry: “Streams of Consciousness”
The biggest environmental challenge we face is educating people
Our globe is a big community
We interact
We affect our surroundings
Without knowledge there is consequence
Specialization is prominent
But familiarity with all systems is essential
To know a tree dies but not why
Could be a plague
We care about trivial things at times
What is on TV?
No, where will my next sip of water come from?
Once we understand
We can adapt
Systems can be in balance
A quiet lake, a deep ocean, and a steep mountain
What can we learn about life?
Careful observation and ongoing education
One day, our world will be of one mind

Coming Next Week – College Bloggers
Students from SUNY-ESF will be taking over Groovy Green next week. Get the perspective of the future environmental leaders of America (and places beyond).
Come back and see us next week, starting Thursday 11/18/10 and see what they have to say.
Can a “One-legged” Man Stay Green?
I’ve had the humbling experience of undergoing ankle surgery about 2 months ago. As a father of a near-two year old, and a husband, it has been extremely difficult to shift from the role of a provider and equal member of the household to a person initially very dependent on others.
My family and friends have been very supportive, and where we still needed some help, we were able to find babysitters, someone to help clean, and someone to do the annual fall clean-up.
I’ve progressed over the last month from a doped-up, leg-elevated, impression in my couch to a semi-functioning member of my family and society. I’m back to work, and trying to catch up on my PhD studies. Still, its a big challenge to hop from place to place, and occasionally catch a ride in a wheelchair during longer outings. Let’s just say that I’ve had plenty of time to think.
Cleveland’s RFID-enabled Recycle Bins Report When You’re Not Using Them
Cleveland’s City Council recently passed a $2.5 million measure to bring RFID-equipped recycling bins to 25,000 homes over the course of the next year. Hey, nothing like encouraging a little green behavior. But this one carries a catch:
The chips will allow city workers to monitor how often residents roll carts to the curb for collection. If a chip show a recyclable cart hasn’t been brought to the curb in weeks, a trash supervisor will sort through the trash for recyclables.
Trash carts containing more than 10 percent recyclable material could lead to a $100 fine, according to Waste Collection Commissioner Ronnie Owens.
The Facts About Bottled Water
Bottled water is surely one of the biggest jokes ever played on humanity. With plentiful supplies of clean water, first world countries still spends a horrifying amount of money on boutique water — some sourced from half-way around the globe.
The image above is but a piece of a stunning infographic from Online Education detailing the damaging effects of bottled water on our planet — and wallets. Check out the full image after the jump below:
Paper Mate Pens – Now with Less Waste…
Paper Mate sent me a few of their new pens and mechanical pencils to try out in honor of Earth Day. Now while I don’t think that compostable pens are the solution to the world’s problems – I guess I have to give credit to companies for trying to reduce waste and come up with solutions to our overflowing landfills.
The pens work just as well as the normal Paper Mate varieties, I’m a blue ink kind of guy. They’re also very comfortable, but that comes at the expense of a non-compostable grip. The ink hasn’t run out yet, but when it does, I’ll throw it in the bottom of my composter and see what happens. It’s supposed to take a year to break down, but with the generous heat from my food waste-leaves-grass combo, maybe it’ll take less time.
Just don’t forget to break the pen down before composting. There are many non-compostable parts that still need to be removed.
Offshore Oil :: Drill Baby Drill :: The Obama Plan
What follows is something I posted in September of 2008. The US presidential campaign was building up steam and I was sick and tired of hearing ‘Drill Baby Drill.’ It made me ill because of the stupidity of the entire argument. I wrote,
Review: The Book of Rubbish Ideas
The Book of Rubbish Ideas is anything but rubbish. It is FULL of excellent tips to help eco-newbies and hard-core Greens see rubbish as a resource, cut down on waste, and save time, money and resources as a result.
Don’t be put off by the quirky cover; author, Tracey Smith, a contented downshifter, aims to take the freaky out of eco, and her book is accessible, practical and positive. There’s no holier-than-thou attitude to reusable nappies, washable sanpro and chicken-keeping; we are encouraged to ditch the guilt for what we are not doing and start feeling good about what we are doing.
Tracey takes you on a tour through the average family home, from bedroom and bathroom through to the kitchen and out into the garden, including the Usually Male Domain of shed and garage, which so often get missed out where decluttering’s concerned.
A Groovy Green Reader Gives Up Her Car
[ed note:] This post was sent to us by Tammy Roberts, from West Yorkshire, UK:
I’M GIVING UP MY CAR
I didn’t learn to drive until I was 30. Up until that point, I hadn’t seen the point of having a car or even having the ability to drive, as public transport was convenient enough. However, 2 months before my 30th birthday, I moved to Plymouth for a new job and for the first time, I discovered how difficult it was to do my outreach work without a driving license – my job covered the whole of Devon and Cornwall. Within 6 months, I passed my driving test and around 4 months later, I bought my first car – my beloved Fiat Tipo. Yes, it was cheap and a bit of a banger and had all the quirks and faults that are found on most Italian cars (it’s a standing joke on Top Gear), but I loved it nonetheless! And, my goodness, did I love the freedom that being a car owner gave me! I was off to the beach at weekends and I drove back home to Yorkshire once a month to visit family and friends. No more sharing my personal space on a 7 hour train journey, and trying to carry my own weight in luggage. It was fantastic! I even moved back to Yorkshire with my car full of my belongings, with a friend following behind, his car equally laden with my stuff. I could not believe that I hadn’t learned to drive sooner and found that I needed my car for work more and more as I moved from job to job When I had my son, 4 years ago, having a car was a bonus. I remember a childhood of long bus journeys to shopping destinations with my mum, gran and my sister and it was so nice to be able to jump in the car with William in his baby seat and set off on day trips or to visit friends.
