The latest in oceangoing green energy comes from Minesto, a spin-off of the Swedish-based Saab Group. The company has been developing technology that hopes to take advantage of the open ocean and its tidal movements in order to generate green and low-impact energy that could supplement and ease our reliance on more traditional, but less efficient energy sources, such as nuclear- or coal-powered plants. Its Deep Green initiative, which originally received a green light several years ago, hopes to use underwater kites to run turbines that will generate electricity.

Deep Green has resulted in several successful tests that Minesto say suggest that tidal kite technology could increase tidal power by eighty percent. In theory, these kites can operate in deep water where low tidal velocities make ineffective other, more traditional forms of tidal energy platforms.

Essentially, the Deep Green tidal kites will be tethered to the ocean floor and, using kinetic energy and automatic rudders, will fly in figure eights with the oceanic tides. Because water is eight hundred times as dense as air, these kites technically could produce eight hundred times the energy as wind turbines. Eventually, tidal kite farms could significantly increase green energy across the world if Minesto is successful.

So, what’s the next step? Well, the company plans to tether a prototype kite off the coast of Ireland in 2011, presuming all the tests run smoothly for the remainder of 2010 . This plan comes on the heels of the company’s having received funding from a Saab, Midroc New Technology, and BGA Invest, in addition to other private investors. Barring any problems, the company will then put a test farm off the coast of Ireland in 2012 and connect it to the Northern Ireland grid. Chief Executive of Minesto, Anders Jansson, hopes to eventually expand service to all of Ireland.

The example of Minesto and companies like it suggest that the oceans will certainly be the next frontier in green energy research and development. We have already seen other projects take shape, such as wave power generators and other tidal generators. All that remains for Minesto’s continued success is that the company must receive approval from the Department of the Environment in Northern Ireland, and it must also deal with the challenge of adapting the system into a commercially viable one.

But, if we know anything about Saab’s past success in aeronautics and automobile technology, we can expect to see this new venture swim, rather than sink.

Google: Feeling Lucky with Investments in Alternative Energy

Thursday, May 20th, 2010

Since its founding in 1998, Google has become much more than a basic online search engine. It has become a worldwide brand, Google Inc. The company boasts a variety of products and services, dealing with and extending beyond the Internet. Examples of their products include Gmail, Google Earth, and the Android line of smartphones. Along with their impressive list of convenient web services and fun gadgets, Google has also recently invested in an experimental highspeed internet project, Google Fiber. According to Rick Needham, the Green Business Operations Manager of the company, Google Fiber will provide an internet connection to one lucky community in the U.S. (ranging from 50,000 to 500,000 individual homes and businesses) at an astounding speed of one gigabit per second, roughly 100 times faster than the average Internet connection most Americans have access to. Madison is one of the lucky cities being considered for the project.

As one of the most rapidly growing businesses in the world, Google needs a tremendous amount of energy to power their various enterprises. On April 30, Google Inc. purchased two wind farms in the plains of North Dakota. According to Google’s official blog, the company calls this significant investment their “first direct investment in a utility-scale renewable energy project.”

According to the website Alternative Energy News, Google’s $38.8 million dollar investment in these two windfarms will yield 169.5 megawatts of energy, which can power up to 55,000 homes (which is also the minimum target group for Google Fiber). Google claims that “the turbines can continuously adjust the individual blade pitch angles to achieve optimal efficiency and use larger blades with 15 percent more swept area than earlier generations, allowing capture of even more wind energy for each turbine.” In addition to the high caliber output of energy, the state of the art technology these turbines run on provides a record low-cost sources of renewable energy.

Through Google.org, the philanthropic branch of the company, the company has announced that they plan on pushing for further reliance on renewable energy for future large-scale projects. Alternative Energy News reports that Google Inc. has indicated to the Federal Energy Regulatory Commission, or FERC, that it will help buy and sell electricity on the wholesale market. Needham confirms Google Inc.’s intentions to invest further in clean energy by stating: “Smart capital includes not only these early-stage company investments, but also dedicated funding for utility-scale projects. To tackle this need, we’ve been looking at investments in renewable energy projects, like the one we just signed, that can accelerate the deployment of the latest clean energy technology while providing attractive returns to Google and more capital for developers to build additional projects.” Google has already followed through on this promise by investing in companies, such as BrightSource Energy and eSource, that focus on developing clean energy technologies.

Google is not only a pioneer of Internet related technologies–the company acts as a strong example for other large companies to follow in the journey towards reliance on clean energy.

Chicago Following a Greener Path

Wednesday, May 5th, 2010

Note: This is a guest post by Dan Grifen. Dan is a student at the University of Utica pursuing a bachelor’s degree in Political Science. He is an active member of the political blogosphere (check him out here and here) and a follower of all things green and progressive.

With some of the brightest young engineers coming straight out of The University of Illinois, it’s no wonder why Chicago is at the forefront of all major green initiatives. This includes the development of land conservation, efforts driven by the Chicago Department of Environment, and many more environmentally friendly projects. Amongst these are the significant advances in green space and architecture during the 21st century.

Chicago’s demand for greener jobs is being answered by companies like the West Pullman plant, which is the largest urban solar plant in the United States. In an article from the Chicago Sun Times, Jim Amedeo, Lead Supervisor, states “Solar plants are only going to get smaller and more efficient, and solar energy will get cheaper to use.” He continues on to discuss the implementation of multiple plants within the city, adhering to the idea of expansion and job openings.

Residential areas are progressively doing their part to ensure a smarter, energy efficient planet by exploring solar alternatives. With the housing tax credit extension, homeowners are more inclined to enhance their efficiency and find new ways to go green. Reports substantiated by NBC of Chicago find that American homes generated twice as much power from rooftop solar panels. Hopefully with the expansion of plants like West Pullman, America will see an increase in solar powered homes and renewable energy.

Leading the way in green civil design in large is Niranjan Shah, CEO of Globetrotters Engineering Corporation out of Chicago, IL. Globetrotters has been granted monies in excess of $13.7 million, all for city consulting and engineering contracts since March, 1994. According to their website, “For over three decades, the Firm has provided a full range of professional architectural and engineering consulting services. [They] have also been active in program management, construction and energy management; property and facilities operation and maintenance; and technology integration and development.”  In building, Globetrotters abides by USGBC guidelines, further promoting sustainability.

With the passing of Earth Day 2010, it’s important that the rest of our nation keep a close eye on the initiatives being taken in Chicago. Even the smallest individual lifestyle changes, such as brushing your teeth with the water off, are a step in the right direction. With the implementation of land conservation and living landscapes, Chicago, along with the rest of the nation will effectively see energy costs go down in the long-term. This will in turn lead to a relatively fast economic incline, not to mention a more sustainable planet.

The Impact of the (Rejected) Clean Energy Jobs Act

Friday, April 30th, 2010

“No other legislative body in history has managed to trash Earth Day and the legacy of Gaylord Nelson as completely as the Wisconsin Senate has this month.”

This emotional quote from Michael Vickerman, the executive director of RENEW Wisconsin, sums up the sentiments of many disheartened Wisconsinites over the State Senate’s decision to prevent a committee to vote on The Clean Energy Jobs Act. The bill, which was backed by Governor Jim Doyle, would have provided funding for creating eco-friendly jobs and stricter regulations on fossil fuel usage. Along with these important initiatives, the bill would have saved an estimated 1.4 billion dollars on electric bills.

With the promise of such great undertakings, why would the Senate shoot down voting on the legislation?

According to Thomas Content, an energy columnist for the Milwaukee Journal Sentinel, those who oppose the bill argue that “State policies that could add to energy prices aren’t the answer at a time when jobs are on the line” and that the bill needs a more refined cost-benefit analysis.

With Wisconsin’s current energy expenditures sitting around sixteen-billion dollars annually, the biggest concern critics have with the bill is an immediate increase in spending, regardless of how the state would benefit from the investments in renewable energy in the future.

Opponents are also fearful about the large investments that energy providers, such as WE Energies, would need to put into generating clean energy to meet the more rigorous renewable energy mandate the bill would institute.

While these concerns are legitimate, the ramifications associated with the bill’s death also provide cause for concern.  Supporters of the CEJA remain quite disheartened by its death due to its vast potential and what it could mean for Wisconsin.

A recent study by Navigant Consulting concluded that the failure to adopt more diligent clean-energy policies would cost the state a large number of jobs over the next couple years. The bill could potentially create as many as 13,700 new jobs in the renewable energy sector by 2015. According to The Climate Group, the jobs would deal with developing renewable energy components such as wind turbines, solar panels, hybrid power trains, and advanced batteries.

If the bill was signed into law with its proposed carbon tax energy bills, The Public Service Commission predicts that energy bills could decrease by a few billion dollars by the time 2025 rolls around.

Along with instigating an increased output of renewable energy, supporters argue that the bill would put Wisconsin back on par with the other states in the country who have adapted bills similar to The Clean Energy Jobs Act. In 2004, a bill was passed that required 10% of the energy produced in the state to derive from renewable energy sources by 2015. While the legislation was groundbreaking at the time, other states, such as neighboring Minnesota and Illinois have since instigated 25% renewable power mandates by 2015. 10 percent is now one of the lowest mandates of the 31 states that have adopted them. Supporters proclaim that the home state of Gaylord Nelson, the founder of Earth Day, needs to get itself back to the head of the renewable energy movement.

Governor Doyle emphasized the importance of The Clean Energy Jobs Act back in February when he said: “This is where the world is going. When I watch this sort of thoughtless opposition come along, it is to me completely reminiscent of the automotive industry in the late ’70s and early ’80s saying, ‘We don’t need mileage standards.’ Look where that led them.”

Despite the immediate spending that would be necessary to stimulate the bill, the benefits in the long run would yield a state relying more on renewable energy sources than fossil fuels and produce a variety of jobs necessary to regulate and develop these energy sources.

While the rejection of The Clean Energy Jobs Act is an unfortunate and counterproductive move by the Wisconsin Senate, more legislation is guaranteed to come along in the not-so-distant future because something needs to be done to put us back onto what Content calls, “the path of energy independence.”

Sustainable Corporations

Saturday, April 24th, 2010

Environmental greenwashing or legitimate concern?

Is there such a thing as a sustainable corporation?

From an admittedly biased perspective, the word ‘corporation’ generally elicits images of large factories, smog, environmental degradation, assembly lines, CEOs, CFOs, shareholders, hazardous working conditions and so on. Ideas on the opposite end of the spectrum qualify ’sustainable’: local, small-scale, regeneration, preservation, organic, green technology, renewable energy, etc. However, this is not always the case for either term.

Recently, I was “strongly encouraged” to open up my mind to the concept of a sustainable corporation. Honestly, I chuckled out loud when I heard those words together. I laughed even harder when I learned that I was to investigate the sustainability of the largest retailer in existence, Walmart. After all, who hasn’t heard of The Walmart Effect?

Despite the relative evils associated with Walmart, their sustainability goals and achievements are quite admirable, especially when compared to other companies. The corporation has broad but straightforward goals with regard to sustainability:

  • To be supplied 100% by renewable energy;
  • To create zero waste;
  • To sell products that sustain people and the environment

With 7,400 stores worldwide, are such goals even achievable?

(The answer is “Yes”).

Last July, Walmart unveiled a plan for a new Sustainability Index. The purpose of the Index is to measure the sustainability of every product the retailer sells. It will be implemented in three distinct phases, with the final phase resulting in “greater transparency into the quality and history of products” so that customers can consume in a more sustainable way. The following description of the phases come from an article I wrote for Leonardo Academy a few weeks ago.

Sustainable Corporation?

Phase One of the Sustainability Index will require Walmart suppliers to dig deep into the sustainability of their products, analyzing all aspects of each product and measuring its environmental footprint. To help suppliers embark on this journey, Walmart designed a 15-question assessment to evaluate supplier energy efficiency. The survey questions focus on four main themes: energy and climate, material efficiency, people and community, and natural resources. Top-tier suppliers were asked to complete the survey by October of 2009, while smaller suppliers were given longer timelines.

The second phase of the Index is the Lifecycle Analysis Database. It involves the creation of a consortium of universities to collaborate with key players, including suppliers, retailers, non-governmental organizations, and government officials. The objective is to establish a global database of product information, including commodity chains and cradle-to-grave—or, hopefully cradle-to-cradle—lifecycles. While Walmart provided the initial funding and resources for the consortium, it is not the company’s intention to administer it. That task will be shared by the University of Arkansas and Arizona State University.

The third phase of the Index is arguably the most important when words turn into actions. When the two phases are completed, the Sustainability Index should function as a valuable resource for customers, providing them with the necessary information to consume in a more sustainable way.

If all goes according to plan, this system will allow both wholesale purchasers (like Walmart) and retail purchasers to drive advances in sustainability by suppliers and manufacturers.

Let us know your thoughts: Does Walmart have what it takes to lead a new era of sustainability or is this campaign simply another form of greenwashing?
