My previous post retraced the precipitous decline in the reputation of biofuels that occurred between 2006 and today.  In this post I’m going to talk about just a few of the activities going on for “second generation” biofuels (beyond corn, soy and palm oil, wheat…).  One of the key features of these initiatives is that they reduce the competition with food crops - something which will only become a more significant issue in the future.  I’ll be talking about several Universities and companies who have hung in there through the ups and downs of oil prices and the “trendiness” and “rejection” of biofuels.  I think that these folks are going to make significant long-term contributions. If you have been soured in the past on the biofuel concept, please consider these alternatives.

Algae

There was a recent Wall Street Journal article about “5 Technologies that could change everything.”  One they included was biofuels from Algae.  People have been working on this for a long time including a very long government effort.  The great thing about algae is that you can grow it in places and with water sources that are completely unsuitable for farming.  Algae can be extremely productive.  The problem is that the low capital investment systems are less productive and the highly productive, “bio-reactor” approach has a huge capital cost.  The good news is that there are enough companies working away on this that sooner or later there might be a break-through.  I won’t pretend to be an expert on how this is going, but I have a hunch it will eventually become significant.

While we selected one of the best-selling residential wind turbines in the US, a 10kW (kilowatt) rated machine built in Norman, Oklahoma by Bergey Windpower Co., there’s still wear and tear common among any machines, especially those that have to stand up to the increasingly severe storms and harsh four seasons in Wisconsin. Now the nation’s leading small wind turbine manufacturer with installations in all fifty states and 100 countries, Bergey Windpower Co. manufactured our entire 10kW Bergey GridTek system that includes our generator and inverter system components.  But parts still wear out; items need replacing.

We installed our grid-tied 10kW Bergey Excel in May, 2003, and — other than a blade switch-out in 2005 to boost production (which it did by more than 30 percent) — we’ve encountered no mechanical or electronic failures or issues. It’s a testament to how reliable some of the wind turbines and inverters have become. Since its installation, we’ve already generated over 48,000 kWhs (kilowatt hours) of renewable energy, presently averaging about 10,000 kWhs/year. Yep, our utility, Alliant Energy, then buys our surplus electricity back from us (it amounts to about $400 a year). According to calculations at Bergey Windpower Co., our 10 kW Bergey GridTek system will offset approximately 1.2 tons of air pollutants and 250 tons of greenhouse gases over its 30-year operating life.

This past September, we hired Kettle View Renewable Energy LLC to complete the replacement of leading-edge tape on each of the blades, tape which was pealing back or slid off altogether. The leading-edge tape helps protect the perfectly balanced fiber reinforced plastic blades — offering about twice the strength of low carbon steel. These Bergey Excel blades have a swept area diameter of 23 feet. Kettle View Renewable Energy, LLC is one of the hundreds of new companies that have started to meet the growing need of servicing renewable energy systems, completing renewable energy site assessments, grant writing and system installations.

It’s getting to be almost a cliché here in San Francisco with large music festivals that have either a green backbone or a heck of lot of social justice behind it. Both Outside Lands and Hardly Strictly Bluegrass sit only slightly in the rear view mirror but this weekend we hit the Treasure Island Music Festival to check out the music, happenings and the overall Green flavor.

Considering that several thousand people crammed into the festival space on Treasure Island we think that overall they handled the transportation issue in a pretty Green way. We made our way to the festival via zero-emission Bauer buses that picked most of the masses up at AT&T Park. The only real griping we heard came from East Bay attendees who said that they had to drive or take BART to SF instead of having shuttle buses come to the East Bay as well.

Upon entering the festival we couldn’t help but noticing the Ferris wheel but then after that we spied a pair of decent size solar panels that sat near the entrance. Unfortunately, we couldn’t determine or find anyone who knew what the solar power generated. We’re sure it the energy went toward something beneficial. Read the rest of this entry »

If life’s a journey, Journey Inn — an eco-inn and retreat that’s designed with nature completely in mind, spirit and body – serves as a guide.

Located in Maiden Rock, Wisconsin, about an hour from St. Paul-Minneapolis, this Travel Green Wisconsin and Green Routes certified enterprise launched by John Huffaker and Charlene Torchia in 2006 artistically crafts a peaceful refuge to enhance our experiences with nature and allow our inner beings to breathe. Journey Inn is part restoration enterprise and part center for recreating our human soul in more meaningful ways.

I had the opportunity to stay at Journey Inn for a couple days this past September with my family, since we prefer ecotravel-oriented accommodation options. We hiked some of the abundant hiking trails on their sixty-six acre property that includes a spectacularly restored prairie and garden labyrinth. We sipped tea while relaxing in their gardens. We even shared a few of our cucumbers and tomatoes from Inn Serendipity with a couple celebrating their honeymoon there.

This past July 4^th some friends and I headed south from our farm to visit the new EcoGrove I Wind Farm in Lena, Illinois, located in Stephenson County (in the northwestern part of the state).

The creation of the EcoGrove I Wind Farm was precipitated by the State of Illinois adopting a Renewable Energy Standard that required the state to generate at least 25 percent of its power from renewable energy sources by 2025. Cleaner air, using an abundant and renewable energy source, and providing various community benefits make wind farm development likely to continue, at least until more Americans change our energy-intensive ways.  From my perspective, however, energy independence is more about breaking free from our fossil fuel addictions to coal, natural gas and oil rather than simply securing domestic sources of energy that are polluting and/or add more carbon dioxide into the atmosphere.

The $200 million EcoGrove I Wind Farm is owned and operated by the sustainability-focused business Acciona Energy North America; its parent company is Acciona S.A., headquartered in Spain. EcoEnergy LLC and The Morse Group managed various aspects of the planning, mapping, permitting, engineering and interconnections for the project.

The EcoGrove 1 Project comprises 67 turbines spread across about eight thousand acres to create a 100 megawatt (MW) wind farm capable of powering over 25,000 homes. Thirty of the 67 Acciona turbines were manufactured in West Branch, Iowa, with the rest coming from Spain. The energy produced is sold to ComEd (Exelon Corporation) which then directs the energy where needed. An additional two phases are planned.

“The upper Midwest has tremendous wind energy potential and EcoGrove is one great step toward harnessing that potential.” said Kimberly L. Smith, Vice President Construction and O&M Services, Acciona Energy North America.

Below are of the few of the benefits in more detail, though our group was blown away by their sleek design of the blades and the way they towered over the emerging cornfields in early summer.

It’s not diamonds.  Nor is it gold.  But it might be just as lucrative. European firms this time have their eyes on North African deserts as the location of a giant network of solar thermal plants to provide low-carbon energy for Europe.

Arizona’s latest advance as a leader in the use of solar technology came last night with the signing of a new bill by Governor Jan Brewer.

The Quality Jobs Through Renewable Industries bill, or Senate Bill 1403, passed in the Arizona House and Senate last month.  With the goal of stimulating new investments in renewable energy projects, it creates new tax breaks and extends credits for solar energy firms in the state.

Want to put solar panels on the house? Start saving… solar power is a great investment, but it is an investment… often a hefty one. If you’d like to get started with something a little less ambitious (but more affordable), you’ll find a number of good sources out there for a whole range of solar DIY projects. Voltaic, best known for its solar backpack, has joined more well-known sites such as Gary Reysa’s Build It Solar and Mother Earth News with its own collection of do-it-yourself projects.

So far, the collection is small… but there are already some really cool projects available:
