Fast Expanding Solar Energy on the Mind of Many for 2012
Jan 16th
Amidst an increasingly tough consolidation phase resulting in a number of high-profile company closures, a trade petition that resulted in the U.S. Commerce Department initiating an anti-dumping and countervailing duty investigation on Chinese PV imports and the fact that the highly successful Section 1603 Department of Treasury Program did not get extended last year (though there is still hope that it will this year), lies the fact that America’s fastest growing industry, the solar energy industry, had a stellar year – despite all the hurdles popping up in its path.
Fact is, the movement in America towards solar is growing stronger every day: For the fourth consecutive year, an independent poll by Kelton Research found that approximately 9 out of 10 Americans (89 percent) think it is important for the United States to develop and use solar energy. What is even more spectacular is the fact that support for solar is greatly non-partisan: 80 percent of Republicans, 90 percent of Independents and 94 percent of Democrats are in rare agreement when it comes to the earth’s most powerful and most abundant energy resource and its development. At a time when politics are characterized by a lack of consensus within parties let alone across party lines, this constitutes a rather unprecedented unanimity.
What is even more encouraging is that Americans are also in agreement on the need for federal investment in solar energy and the need for the government to provide incentives for it. Well aware of the fact that traditional and non-renewable energy sources like oil, natural gas, and coal have received billions in government support – and continue to do so, despite the fact that these energy sources have long matured — the great majority of citizens (82% to be exact) feel it is only fair to award solar the same assistance, whether it be in the form of grants or tax credits. If consumers are receiving tax credits for purchasing energy efficient appliances, for example, it seems logical in the public mind to extend the same support when “doing the ultimate deed” and investing in the energy future of the country by installing a photovoltaic or solar thermal system. Translated into party affiliation again, 71% of Republicans concur with the notion of federal support for solar, 82% of the Independents, and 87% of Democrats.
This resounding success for solar stems from the fact that solar won hands down when those surveyed were asked which energy source they would support financially if they’d be in charge of energy policy. Solar is almost twice as popular as the next highest scoring energy source: 39% of Americans see the benefit of financial assistance for solar, followed by a mere 21% for natural gas. Coal and nuclear power are trailing far behind in the single digits (nine and three percent respectively). Especially young and working-age Americans who are hard pressed for jobs as only their grandparents have been before during the great depression, realize that solar’s potential for job creation and economic growth is far greater than that of any other energy resource.
In 2011, the solar industry grew faster than any other job sector in the United States, at a staggering 26% growth rate.
Currently more than 100,000 Americans are employed installing, manufacturing, or selling solar products and this number is expected to grow by another 24% over the course of the next year. The majority of green collar workers are employed by small to mid-size businesses installing solar technology—exactly the kind of businesses that make up the back bone of the American economy and that had to struggle the hardest to survive the recession, oftentimes by having to lay-off experienced and trusted employees. The fact that these businesses can hire again, and have even disclosed to hire 25% more workers in 2012, is a strong sign that economic recovery has a green driver. Also the manufacturing side has plenty of reason to be proud since in 2011 the U.S. was a $2 Billion net exporter of solar products, even only with China. Over the last two years, 27 new manufacturers have begun production in the United States; a multi-billion economic investment and a clear sign of market confidence.
The solar boom is of course aided by the fact that the price for even higher performance and quality engineered technology, be it high-efficiency modules or innovative, time-saving racking systems and many other features, has dropped 30% since early 2010. From $60 per watt in the mid 70s, a watt of produced silicon PV modules has dropped to about $1.50 today. The immense number of PV installations in Q3/2011- 449MW- alone confirms the sunny outlook for solar in the United States: never before has this much solar been installed in any quarter before. Not only a record quarter but also a phenomenal 140% growth over Q3/2010 and more than all installations of 2009 combined.
With prices continually decreasing and demand and efficiency exponentially rising, more and more American consumers are the main beneficiaries. Experts even predict that by 2016 solar PV will outperform the cost of coal as well (roughly 9 cents per kilowatt hour), making it a clean energy choice of superlatives: universally adaptable, cost competitive with traditional, non-renewable resources, as well as extremely fast to install. In 2011, almost 2 GW of solar were permitted and installed in the U.S.; in comparison nuclear power plants with an equal capacity take an average of 13 years to complete. As the global demand for energy continues to rise, the U.S. has one of the best opportunities in the world to position itself as a leader in solar energy. Not only does America possess some of the best solar irradiation on the planet and is therefore excellently suited to harvest the sun, but this country’s motivated workforce along with its talent pool in research and development are second to none.
Finally the sunny outlook for solar in the U.S. is bolstered by the fact that by 2014 the U.S. is expected to become the world’s largest solar market and the technology is likely to be the largest source of new electric capacity in America. As we welcome back the brave and commendable veterans of the Iraqi War, the solar industry’s enormous job growth potential represents a much needed opportunity to integrate the heroes of the American spirit back into our economy. I predict that the solar industry will enhance its workforce with many of these well-trained individuals who are adaptable to change and experienced in working with cutting-edge technology. It will be our testimony that we did not take their service for granted and are grateful for the sacrifices they have made for our country. Going forward American solar businesses will grow and take care of their own, while solar adaptation in the United States lets the rest of the world know that we, too, understand the need to diversify our energy portfolio and are ready to mark our true energy independence in the 21st-century.

India Embraces Solar Power, Says Price Will Equal Thermal Power in Five Years
Dec 15th
Economic South Asian superpower India has firmly embraced solar power, advancing the target date by five years for selling solar-generated electricity at the same rate as electricity generated by fossil fuel plants, from 2022 to 2017.
According to government officials, the reason for moving the date forward is plummeting tariffs in the latest solar development projects, a trend that they believe is likely to continue.
Ministry of New and Renewable Energy Joint Secretary Tarun Kapoor said, “The prices will come down further next year and will continue to fall. Earlier, our aim was that solar power will achieve grid-parity by 2022, but looking at the upbeat response from the industry, we have now reduced our target to 2017. Some big names from India have proved that a large investment will soon be possible in solar projects, as huge as 2,000 megawatts. There are other reasons as well. Internationally, the price of solar cells has come down and with improved technology, the cost of operation as a whole has been reduced, thereby increasing the efficiency.”
All is not yet completely sunny for India’s solar energy drive, however. Kapoor noted that several solar projects benefiting under a state program offering favorable tariffs to build 20,000 megawatts of capacity have already been delayed, adding that developers may lose contracts if deadlines are missed, commenting, “Two of the projects are behind schedule. In a few months, we should have a clear picture.”
The pair of miscreants are Entegra Ltd., whose majority shareholder is MW Corp Pvt., which has yet to begin building a 10 megawatt solar-thermal plant in Rajasthan and Enterprise Business Solutions, cited for delays in an October deadline to build a 5 megawatt photovoltaic plant in Punjab.
Entegra Ltd. is disputing New Delhi’s claims of sluggish performance, with its Chairman Mukul S. Kasliwal commenting that his firm faced problems raising financing for its $38 million development but that the company expects to complete the Rajasthan facility plant by its 2013 deadline. Shifting responsibility for delays to the Indian government, Kasliwal commented in an interview, “We haven’t started because we’re not going to do something that doesn’t make sense financially. Had we been allowed to function as an SPV (special purpose vehicle), then we would’ve finished financing long ago.”
Despite the travails of Entegra Ltd and Enterprise Business Solutions, other members of India’s burgeoning solar energy community are optimistic about the government’s latest pronouncements. Azure Power CEO Inderpreet Wadhwa, whose company has secured government contracts to establish solar projects to generate up to 35 megawatts said, “Solar has the same potential as personal computers had in 1970′s. Technology innovations and improvements in manufacturing would drive down costs further.”
Support for India’s solar ambitions comes from some heavyweight fiscal analytical groups. Ernest and Young partner Sanjay Chakrabarti observed, “The extent of price reduction since 2008 has been very sharp. Although solar prices will continue to drop the fall in future may not be so sharp.”
Kapoor is under no illusions however as to why foreign companies are closely following India’s interest in solar energy, noting wryly, “The only reason is that India is an emerging market and one of the few countries where solar energy is encouraged at such a massive level.”
And that emerging market is potentially lucrative indeed, as last year the Indian government launched its “National Solar Mission,” whose objective is to establish India as a global leader in solar energy, by creating the policy conditions for its diffusion across the country as quickly as possible.
The program’s goals are nothing if not ambitious, as the government had initially hoped to boost the nation’s solar capacity by the equivalent of about 18 nuclear power plants by 2022, a date that’s now been brought forward by five years.
Investors, anyone?

Whole Foods Receives EPA Recognition For Eco-Friendly Foggy Bottom Location
Nov 1st
Kathy Loftus and Mark Hughes, of Whole Foods, discuss their reasoning for joining the EPA’s Green Chill Partnership Program and the approach they took to lowering CO2 emissions on their Foggy Bottom store.
| Ben Lack: | Whole Foods has recently received recognition from the EPA for having eco-friendly refrigeration in your Foggy Bottom location in Washington, DC. I wanted to get your thoughts on why Whole Foods sees value in becoming part of the Green Chill Partnership Program and what steps did you have to take to meet those standards? |
| Kathy Loftus: | Back in 2007 we were already an EPA Energy Star partner and an EPA Green Power partner and we really enjoyed our work with those partnerships as we were able to network with other partners and get a lot of resources from the EPA consultants and a lot of information that helped us run our business more efficiently. But EPA came to us in 2007 and asked us if we would consider being a founding partner of a new program they have which is called the GreenChill Partnership Program and it was very intriguing to us because we all were aware, in the supermarket industry, that with the Montreal Protocol and the changing-out of some of the ozone depleting refrigerants that there were going to be some needs to test state of the art alternative refrigeration systems as well as figure out new refrigerants to use that would be lower ozone depleting. As well as trying to balance that with using refrigerants that didn’t have as high a global warming potential.So, we were excited to join on as a founding partner, I think we were the first partner to sign on actually and the goal for that was two-fold. Number 1, absolutely not build any new stores with ozone depleting refrigerants and when we were remodelling stores to change the refrigerant to a non ozone depleting refrigerant and then also assist the EPA by designing different refrigeration systems into our stores so that we could evaluate what other impacts those systems had. So, for example, we were looking at glycol systems for medium temperature instead of refrigerant. We were also looking at CO2 as a low temperature refrigerant and we were looking at distributed systems. But we were really trying to help get on the numbers, if you will, so that big industry could learn from our installations. So, those were the 2 goals, reduce ozone depleting substances and test and evaluate alternative refrigeration systems. So, we joined. |
| Ben Lack: | Mark, your turn. |
| Mark Hughes: | Basically, this was a very interesting project for us in the Foggy Bottom project. It was always slated by the city council to have a grocery store here and there were many other operators that were sitting at the table interested in coming to this location. Whole Foods was sitting at the table some 4 years ago and we helped foster the property and do some engineering to try and get the systems there. In the mean time, some of the other operators had advanced their negotiations and we weren’t at the table anymore. When we finally came back to the table we were extremely late in the game so we didn’t have as many options as we had in the beginning and distributed systems was the most practical means to achieve what we need.The distributed systems are basically placing the refrigeration racks very close to the loads and thereby reducing the refrigerant charge and then using water from a cooling tower to operate our condensing. We didn’t need big refrigerant loads to go to the roof. We used a cooling tower and water glycol system in a closed loop to achieve this lower refrigerant charge. It was basically coming to the dance late that pushed us to use the distributed systems and then we also tried to make use of taking the stranded heat generated by the refrigeration and turned around and helped the heat pumps operate in the winter time. So, we are using a combination of heat pumps and distributed refrigeration systems. |
| Ben Lack: | And what’s the impact of taking this type of approach to the facility? How has that helped you save in CO2? |
| Mark Hughes: | The distributed systems basically place the racks very close to the loads, so the freezer cases that you see downstairs could operate very quietly that just has enough refrigerant charge to run those cases. That’s the beauty of distributed systems in reducing the refrigerant charge. |
| Cathy Loftus: | One thing as Mark mentioned is having that system designed so that the refrigerant is close to the load is one thing, but also when you design a system that has a lower charge, there’s less of it to leak. We all know in the supermarket industry it’s unfortunate but there are a number of reasons why we may have small emissions of refrigerant over the course of the year except when the equipment is in service. So, when you design a store to have lower refrigerant charge and have those piping loops run closer to the load, there’s much less of a chance of a leak; there’s a lower leak rate as it is. So, that’s how you reduce your greenhouse gas emissions because the refrigerant that gets emitted contributes to greenhouse gases. |
| Ben Lack: | This strategy that you took in the Foggy Bottom store, is this the first time that you’ve taken this approach or has this approach worked in other stores as well? |
| Mark Hughes: | It’s definitely working in other stores, it’s a proven system. The protocol systems have been out there probably, I’m going to guess, 12 to 15 years. |
| Kathy Loftus: | Yes. What I would say though is what Mark did that’s unique and that we haven’t done in a lot of other stores or regions at least in Whole Foods’ market is, Mark utilized a plate to plate heat exchanger in that store’s design so the refrigeration and HVAC systems are somewhat coupled, so not only have we reduced greenhouse gas emissions by having a low charge refrigeration system, lower leak rate, we also have reduced greenhouse emissions because this system that he designed will save a ton of natural gas usage because we will be using waste heat from the compressors to operate heat pumps which are highly efficient most of the year in that region. So, the engineers estimate that we are going to be saving a lot of b.t.u. and a lot of natural gas that would otherwise have been required for heating for that store. |
| Ben Lack: | As you guys move forward and work on other locations, what’s next for you as you try to make these stores more sustainable and responsible about energy use? |
| Kathy Loftus: | There’s a lot of great things that we have done over the past couple of years with leaders like Mark who are willing to go out on a limb with new designs and new ways of designing the stores, not only for energy efficiency and reduced refrigerant but also for other green building attributes and zero waste initiatives. We’ve got electric vehicle charging stations, we’ve got solar on many stores, Mark’s team is one of the first ones to purchase outright a PD system for the Princeton store. But, we’ve got solar on almost 20 locations now.We’ve got fuel cells at 4 and we are just about to start operating a generator at our North Atlantic region commissary that will run off of waste cooking oil from the stores and commissary in that region and that cooking oil is not actually transferred into a biodiesel. It’s literally just filtered and used as a fuel for this generator that will be operating on-site providing all the stores both heat and power and backup power. It’s a win-win for that community because the utility was transmission constrained and was thinking about having to build new feeders and eventually new power plants.So, what we try to do is take the stake-holder model approach where green emissions have always been at our core but we want to continue to grow and lead in areas like having green building certification, so we’ve got many LEED certified stores we’ve got several gold at this point. We also have Green Globe certified stores and many of those have 3 Green Globes which is equivalent to LEED gold so lots of our stores are being built to either LEED or Green Globe standards even if they don’t go through with the certification. But we feel that what’s new on the horizon is really looking at what makes sense in each community, designing the stores in the back of the house to be as efficient as possible with respect to zero waste goals and efficiency and day-lighting. There’s been a lot more day-lighting in the back of house because it’s not only is saving on lighting energy but it’s actually really good for the folks that work back there for productivity and efficiency. We try to take this holistic approach where depending on where the building is located in the country. It may make sense to use the roof for day-lighting or solar or a combination of the 2. Or other types of analysis that we do to see what makes the most sense in that climate, in that region, what kinds of subsidies are available because often with the new technologies that are out there, it really makes sense for us to try those when there are some incentives. When the demand for that type of technology increases the costs will come down and then the incentives will no longer be available or necessary. But we do take this approach of really trying out lots of new technologies. In fact, we’ve just been presented with another one, a liquid desiccant HVAC retrofit option that we may test in conjunction with the National Renewable Energy Lab and other tests for the labs out there like the University of California Davis. So, we really do try to work closely with all of our constituents and take this holistic model that really considers everything. |
| Ben Lack: | Why have you chosen to spend your time doing what you’re doing and why does this work mean so much to you? |
| Mark Hughes: | This is an unbelievably exciting area of technology and it’s changing everyday. There are so many different kinds of systems out there, it’s really interesting because you can get to choose and play with them and actually shift them around or mix them as a hybrid. So, you can take any number of approaches to the refrigeration HVAC and I don’t think there’s any other mark, even if it goes this way or that way, it’s wide open field and it’s pretty exciting. |
| Kathy Loftus: | Coupled with the fact that there’s so much more information technology out there today and the information is at your fingertips much more quickly with the internet and with some sophisticated modeling and tools. The thing that really grabbed my attention years ago was when I started working in the buildings field and engineering field 20 years ago and seeing how architects got the bulk of the dollars to design a building and when it came down to the mechanical, electrical and plumbing engineering, they were just really doing quick designs for cost reductions and not necessarily considering long term operating costs or what those energy or other impacts had on the environment.There are a couple of folks that I learned from early on that were willing to take and do some extra analysis and see what the long term benefits could be and just over the last 10 years has been leaps and bounds in being able to share that information and really start to look at how to design a building, not only for the lowest first cost but for the lowest long term operating costs and net impact on the environment. For me, it’s always been a passion about reducing resources that, waste kind of makes me crazy. I think Mark and I are cut from the same cloth in that respect. |
| Mark Hughes: | There are so many systems out there. Twice or three times I tried to do the geothermal systems and I still with this company, they allow you to mess around with this stuff as long as you stay within your budgets, they really allow you to be an entrepreneur. Mark my words one of these days I will put in whether it’s a hybrid or something, I will put in a geothermal system. It’s just interesting, very interesting and exciting. |
