Understanding Carbon Emissions

Carbon emission is one of the hottest issues in the world of energy and environment today. While it is supposedly an essential component of the ecosystem, it has already become a large contributing factor to climate change. Carbon emission might be good but abuse of this natural process has made it harmful to people across the globe.

This series of articles aims to help people understand the intricacies of carbon emission and what society can do to efficiently manage this natural occurrence.

Natural Carbon Cycle

Two important elements in the carbon cycle are carbon, which is present in every living thing all over the world; and oxygen, which is found in the air that people breathe. When these two bond together, they create a colourless and odourless greenhouse gas known as carbon dioxide, which is then crucial to trapping infrared radiation heat in the atmosphere and also for weathering rocks.

Carbon is not only found in the atmosphere of the earth. It is also an element found in oceans, plants, coal deposits, oil and natural gas from deep down the earth?s core. Through the carbon cycle, carbon moves naturally from one portion of the earth to another. Looking at this scenario, one can see that the natural carbon cycle is a healthy way to release carbon dioxide into the air in order to be absorbed again by trees and plants.

Altered Carbon Cycle

The natural circulation of carbon among the atmosphere is vital to humankind. However, studies show that humans misuse this natural cycle and abuse it instead. Whenever people burn fossil fuels such as coal, oil and natural gas, they produce carbon dioxide ? which is an excess addition to the natural flow of carbon in the environment. The problem is that the release of carbon dioxide is much more than what plants and trees can re-absorb. People are not only adding CO2 to the atmosphere, they are also influencing the ability of natural sinks, such as forests, to remove it from the atmosphere. Humans alter the carbon cycle by contributing doubled or tripled greenhouse gas to the atmosphere, faster than nature can ever eliminate. Worst, nature?s balance is destroyed.

The Result

Greenhouse gases include carbon dioxide, methane, nitrous oxide, fluorinated gas and other gases. Although these gasses contribute to climate change, carbon dioxide is the largest greenhouse gas that humans emit. The reason why people talk about carbon emissions most, is because we produce more carbon dioxide than any other greenhouse gas.

The increasing amount of carbon emissions cause global warming to become more evident. All the extra carbon dioxide causes the earth?s overall temperature to rise as well. As the temperature increases, climate also changes unpredictably. Flood, droughts, heat waves and hurricanes are now widely experienced even in places where these phenomenon never used to happen.

To be able to reduce the risk of more severe weather conditions means burning less fossil fuels and shifting more to renewable sources. This is never easy. But, definitely, it’s worth a try.

Saving Energy Step 2 ? More Practical Ideas

In my previous blog, we wrote about implementing a management system. This boils down to sharing a common vision up and down and across the organisation, measuring progress, and pinning accountability on individuals. This time, we would like to talk about simple things that organisations can do to shrink their carbon footprints. But first let’s talk about the things that hold us back.

When we take on new clients we sometimes find that they are baffled by what I call energy industry-speak. We blame this partly on government. We understand they need clear definitions in their regulations. It’s just a pity they don’t use ordinary English when they put their ideas across in public forums.

Consultants sometimes seem to take advantage of these terms, when they roll words like audit, assessment, diagnostic, examination, survey and review across their pages. Dare we suggest they are trying to confuse with jargon? We created ecoVaro to demystify the energy business. Our goal is to convert data into formats business people understand. As promised, here are five easy things your staff could do without even going off on training.

  1. Right-size equipment? outsource peak production in busy periods, rather than wasting energy on a system that is running at half capacity mostly.
  2. Re-Install equipment to OEM specifications ? individual pieces of equipment need accurate interfacing with larger systems, to ensure that every ounce of energy delivers on its promise.
  3. Maintain to specification ? make sure machine tools are within limits, and that equipment is well-lubricated, optimally adjusted and running smoothly.
  4. Adjust HVAC to demand ? Engineers design heating and ventilation systems to cope with maximum requirements, and not all are set up to adapt to quieter periods. Try turning off a few units and see what happens.
  5. Recover Heat ? Heat around machines is energy wasted. Find creative ways to recycle it. If you can’t, then insulate the equipment from the rest of the work space, and spend less money cooling the place down.

Well that wasn’t rocket science, was it? There are many more things that we can do to streamline energy use, and coax our profits up. This is as true in a factory as in the office and at home. The power we use is largely non-renewable. Small savings help, and banknotes pile up quickly.

Competencies, Roles and Responsibilities of Lead Assessors

Any organisation that opts for energy audits, Display of Energy Certificates and Green Deal Assessments needs a lead assessor to review the chosen ESOS compliance routes. The Derivative provides that energy audits should be carried out independently by qualified and accredited experts. Additionally, these audits should be implemented as well as supervised by independent authorities under the national legislation.

Lead assessors undertake several roles in ESOS assessments. He or she is the one responsible to take the lead of the entire assessment team, prepare the plan, conduct the meetings and submit the formal report to governing authorities. Nevertheless, selecting an appropriate lead assessor is an important element that every organisation should carefully consider.

Competencies Requirements of Lead Assessors

Lead assessors should be knowledgeable enough with in-depth expertise in carrying out energy efficiency assessment. They should also possess foundational, functional and technical competencies to deliver the task effectively. Likewise, consider the assessors? sector experiences, familiarity with your business? technologies and properties, and accreditation with prescribed standards.

As you choose your lead assessor, contemplate on the skills and qualifications that would give your organisation benefits.

Roles and Responsibilities of Lead Assessors

The business organisation is responsible for the overall legal ESOS compliance. Moreover, here are some of the roles and responsibilities that lead assessors should assume in ESOS assessments.

The lead assessor agrees on the audit methodologies that the organisation would undergo in new audits. He or she agrees with the ESOS participant regarding the audit timetable, sampling approach and visits required. It is also the lead assessor?s role to identify the opportunities on energy saving and assist in calculating the cost savings from the measures taken. During the ESOS audits, the lead assessor determines the energy use profiles, presents the recommendations and reviews the entire assessment as a whole. Furthermore, he or she should maintain the evidence pack of the ESOS to uphold the audit’s credibility, its findings and recommendations.

Finding Lead Assessors

Energy and environment professionals would only be able to demonstrate their expertise as lead assessors upon registering in a professional body accredited by the Environment Agency. Any business that needs a lead assessor is advised to check on the EA?s website to see the details of approved registers.

Lead assessors can either be in-house experts or external professionals. However, they should be able to provide proof of membership as an approved register to take the role of a lead assessor. If the organisation has an internal lead assessor, the company should then take the final ESOS assessment to two board-level directors that would sign the formal report.

Indeed, the lead assessor is an organisation’s partner when it comes to delivering great results. With good professional conduct and excellent management of an assessment team, the lead assessor can help achieve breakthrough energy efficiency strategies. More than anything else, the organisation will benefit from maximum energy savings opportunities ahead. Thus, every qualified business enterprise should invest in finding the best lead assessor to guide them towards success.

What Sub-Metering did for Nissan in Tennessee

When Nissan built its motor manufacturing plant in Smyrna 30 years ago, the 5.9 million square-foot factory employing over 8,000 people was state of art. After the 2005 hurricane season sky-rocketed energy prices, the energy team looked beyond efficient lighting at the more important aspect of utility usage in the plant itself. Let’s examine how they went about sub-metering and what it gained for them.

The Nissan energy team faced three challenges as they began their study. They had a rudimentary high-level data collection system (NEMAC) that was so primitive they had to transfer the data to spread-sheets to analyse it. To compound this, the engineering staff were focused on the priority of getting cars faster through the line. Finally, they faced the daunting task of making modifications to reticulation systems without affecting manufacturing throughput. But where to start?

The energy team chose the route of collaboration with assembly and maintenance people as they began the initial phase of tracking down existing meters and detecting gaps. They installed most additional equipment during normal service outages. Exceptions were treated as minor jobs to be done when convenient. Their next step was to connect the additional meters to their ageing NEMAC, and learn how to use it properly for the first time.

Although this was a cranky solution, it had the advantage of not calling for additional funding which would have caused delays. However operations personnel were concerned that energy-saving shutdowns between shifts and over weekends could cause false starts. ?We’ve already squeezed the lemon dry,? they seemed to say. ?What makes you think there?s more to come??

The energy team had a lucky break when they stumbled into an opportunity to prove their point early into implementation. They spotted a four-hourly power consumption spike they knew was worth examining. They traced this to an air dryer that was set to cyclical operation because it lacked a dew-point sensor. The company recovered the $1,500 this cost to fix, in an amazing 6 weeks.

Suitably encouraged and now supported by the operating and maintenance departments, the Smyrna energy team expanded their project to empower operating staff to adjust production schedules to optimise energy use, and maintenance staff to detect machines that were running without output value. The ongoing savings are significant and levels of shop floor staff motivation are higher.

Let’s leave the final word to the energy team facilitator who says, ?The only disadvantage of sub-metering is that now we can’t imagine doing without it.?
