Part II: 10th Annual NC Sustainable Energy Conference

April 22nd, 2013


After an informative and entertaining session on sustainable agriculture, I ventured out into the expo hall and car show to do a little exploring. Just outside Mckimmon in the front parking lot, the green car show was taking place, showing off the latest on-the-road alternative fuel cars and unique designs. Here are a few vehicles that you might see on the road locally or elsewhere in North Carolina.

A hybrid diesel-electric school bus from Thomas Built Buses. Increasing fuel efficiency in public transport is a high priority among several towns and cities across the state.

Dodge Ram pickup fitted to run off of natural gas, from Piedmont Natural Gas. With natural gas prices at historic lows, alternative fuel vehicles such as this one may help reduce the cost of fueling your car.

A fully electric Mitsubishi from CBS Mitsubishi Motors in Durham, NC.  This vehicle has a 62 mile range per charge (112mpg equivalency) and options for installations for home electric charging stations. (mitsubishi.com)

This unique assisted bike-vehicle is called the ELF from Organic Transit, built here in the Triangle. There is a Li-ion battery pack aboard, charged by 30W rooftop solar panels that assists the driver, or you can choose manual cycling operation. (organictransit.com)

A late model Mercedes-Benz retrofitted to run off of biodiesel. This is not a new vehicle, and has been very popular among enviro-friendly crowds in years past. Not to mention you still receive the luxury driving quality of a Mercedes-Benz automobile. :)

The expo hall featured several major companies, including CREE, ABB, and Advanced Energy, as well as public and non-profit organizations like the North Carolina Solar Center, NC Sustainable Energy Association, and NC A&T University Ph.D. Program in Energy and Environmental Systems. In between breakout session talks, the expo hall offered free refreshments and made for an ideal place to meet and network with people in the solar industry. I had the opportunity of meeting a few students currently in the Certificate in Renewable Energy Management course I attended last summer and was able give them a few pieces of friendly advice.

Several vendors were present in the Expo Hall to present products and ideas to customers throughout the conference

The 2nd day conference talks I attended dove much deeper into the specifics of renewable energy in North Carolina, particularly in the game of politics and finance. Currently there has been a strong push in the state congress to repeal the Renewable Energy Standard Portfolio, which requires our state to generate 12.5% of its power from renewable sources, including a 0.2% carve out specifically for solar electricity. In addition, the 35% state renewable energy tax credit is also in jeopardy, threatening the future of our industry. As for this moment, deals are continuing to be done at all scales of production, but few panelists could make confident predictions for the state of the industry at this time next year. Please contact your local congressman and let them know you support solar in North Carolina!

The final day of the conference features two great keynote speakers, Ty Mitchell, Executive Vice President and General Manager for CREE Inc., who spoke about the advantages of using LED lighting technology. Cities that have switched their street lighting over to LED has saved hundreds of millions of dollars in energy and labor costs in doing so, thanks to the low wattage use of LED's and their long-lasting life cycle. In fact, 1 LED light bulb will last approximately the same length of time as 25 regular incandescent bulbs. The lunch speaker, and my favorite of the conference, was Cheri Chastain, the Sustainability Manager for Sierra Nevada Brewing Company. She was quick to mention she did not have any free samples for the audience, which brought some laughs and good vibes. She then went into discussing the hard work that has been done to follow owner Ken Grossman's vision of his company to be green and energy independant, including installing 2MW fuel cells at their California plant, over 1000 solar panels on nearly every roof space available at their entire facility, and a move to open a brewing facility in North Carolina, where they fully intend on enacting a similar green policy approach to their brewery.

It was a big week for all of us, I hope you enjoyed this article and feel inspired to attend the 11th Annual Sustainable Energy Conference in 2014! Have a Sunny week!

Discussing Renewables at the 10th Annual North Carolina Sustainable Energy Conference, Part 1

April 18th, 2013


The 10th Annual North Carolina Sustainable Energy Conference (April 15th-17th, Mckimmon Center, Raleigh, NC) recently concluded, boasting one of its largest attendances in the history of the conference, with a record number of keynote speakers and breakout session talks. I had the pleasure of attending all three days, and left feeling both excited and a little concerned about the future of renewable energy in North Carolina.

Tuesday Opening Keynote Session with Marilyn Brown, Professor, School of Public Policy, Georgia Tech

The Monday session of the conference started in the afternoon and presented to a smaller crowd as an introduction to the week's sessions. Eric Lightner, Director of the Federal Smart Grid Task Force with the U.S. Department of Energy, gave the opening lecture "Ongoing Smartgrid Activities at the U.S. DOE" where he provided insightful updates and global energy statistics. The microgrid panel discussion then moved on to speak about U.S. microgrid studies, including a small presentation on solar in affordable housing communities, as well as the grid effect in New Jersey from Hurricane Sandy last year, where an estimated $11.7 billion was lost in that state alone (Rutgers Univ. Study).  The breakout sessions, expo hall, and hybrid car show did not begin until the following morning. A reception was held each day of the conference to conclude the day's activities.

Tuesday was the beginning of the 'bulk' of the conference program, where following a keynote morning lecture on U.S. energy policy from Professor Marilyn Brown at the School of Public Policy at Georgia Tech University, attendees divided up into the smaller lecture rooms at McKimmon Center for the breakout session talks. There were several choices of sessions to attend, from Industrial Energy Systems, Policy and Finance, Sustainable Agrictulture, Utility Initiatives, and several other bonus sessions. After perusing a few of the first morning breakout session choices, I opted to attend the sustainable agriculture lecture, which was moderated by Jeff Thompson, Orange County Assessment Manager.

Tuesday Morning Breakout Session: Sustainable Agrictulture

Each breakout session would consist of 3 or 4 panelists that present their thoughts and ongoing projects related to the lecture. In the sustainable agriculture lecture, the highlighted motif of each talk was the need for more reliance on local produce, farmers markets, and renewable energy to help sustain long term food availability. The importance of not becoming reliable on foods shipped in from great distances will greatly diminish future costs such as transportation, fuel costs, and transactions of service. In case you haven't been before, the Raleigh Farmers Market is open every Saturday on Centennial Way near downtown Raleigh. If you get a chance, please come visit and check out all the goods and local produce grown right here in our state! The importance of savings using local produce, educating children, avoiding fast food, and finding committed vendors for farmers markets was stressed by speaker Kelly Blanford from Sustainable Sandhills. Larry Kent from the NC Cooperative Extension spoke about the solar panels recently installed at the farmers market coop. Matthew Royball discussed his work at the Piedmont Food and Agriculture Processing Center, a large shared kitchen facility that houses several local businesses from farmers to bakers to caterers.

 The final speaker was Chad Ray of Ray Family Farms, who presented on his efforts in sustainable agriculture, which included raising sheep used for grass maintenance in large scale solar farms. He has partnered with O2 Energies to supply sheep on solar farms and help keep grass from overgrowing and requirement mowing and trimming, which can be an expensive and laborious task. Once the sheep have matured, he then sells them to Whole Foods Market. This creative synergy with O2 Energies, Ray Farms, and Whole Foods provides a three-fold solution that benefits each business. He plans to provide sheep for 14 solar farms over the next 6 months. In addition, he also mentioned he received grants from the USDA and the Tobacco Leaf Fund to place 42 solar panels on his farm that produced $1,762 in energy savings last year.

Part II of my article will discuss the hybrid car displays and lectures from the late Tuesday and Wednesday sessions. Have a sunny weekend!

Solar Across the Pond Part 2: Austria and Germany!

April 4th, 2013


After having an amazing journey in beautiful Scotland, I boarded a London flight to make the second half of my adventure in central Europe, a trip to Austria and Germany to meet old friends and see the state of solar in what many have titled the solar capital of the world. Germany outranks all other countries when it comes to solar production, largely due to very generous feed-in tariffs and other government backed solar incentives.

In Austria, renewable energy sources make up the majority of the small nation's power, but this is almost entirely from hydroelectricity, which provides about 55% of Austria's power generation. A smaller portion from wind and biomass make up the next biggest tiers of renewable power sources. Just another great reason out of many to visit this small yet gorgeous country.

Stunning views and cultural history of the beautiful city of Salzburg bring millions of tourists each year

Just a few minutes drive to the north will lead you into Germany, and the renewable landscape changes dramatically. We spent a sunny Sunday afternoon in Schoaramer visiting the local beer hall and having lunch.

A classic German meal, Wienerschnitzel, and a locally brewed wheat beer.

But outside, everywhere you look there were solar rooftops in place. This is extremely common, especially in more rural towns and villages. I was impressed, inspired, and hopeful for the US all at the same time. If we were as progressive as Germany in using solar electricity, we would be way ahead of the game. It's time to step it up America!

 I've put a few pictures up just to show you some of the homes and buildings we saw driving along the road. Every direction you looked, there was a home or building with solar panels. It's quite a sight to see!

It was quite common to see solar on several rooftops in a small village like this one.

Making FULL use of your rooftop!

Unfortunately, all good things come to an end, as did my solar tour of Europe. I had a wonderful time, and thank all of my friends who helped me along my journey and made it such a wonderful time that I will never forget. I hope to be back again soon, and until then I hope to see these kind of inspiring images on rooftops in America! I'll leave you with one last fun image of a great example of what southern Germany and Austria is like. Thanks!

This is how they drink in Germany :)
