Energy Efficiency Matters

For my internship I worked with Conservation Services Group (CSG) located in Westborough, Massachusetts. CSG is an energy efficiency company that operates by working in collaboration with various utility companies and state agencies throughout the country and helps to design and implement energy efficiency programs for the utility companies to use. CSG gives suggestions and recommendations on how the utility companies can meet their energy saving goals. The utility companies fund the energy efficiency programs and CSG helps them with the implementation and design. The utility companies then use the programs and have home energy specialists or auditors go into residential households and corporate buildings and give them suggestions on how to make their home or building more energy efficient, also known as a home energy assessment or audit. CSG operates throughout the country and is a non-profit company. CSG works in collaboration with well-known utility companies such as NSTAR and National Grid. Also, CSG is actually the number one energy efficiency company in the United States and I felt very fortunate to have the opportunity to intern for such a prestigious and well-known organization.

During my time as an intern at CSG I worked on various projects and case studies in the marketing department. CSG supplied me with my own desk, laptop, computer monitor, and various desk supplies that I used to complete different projects throughout my internship. I worked on several case studies related to customer engagements and the contact center. The purposes of these case studies were mainly trying to figure out ways to make the customer engagements smoother and as timely as possible, and determine anything that might be inconvenient to the customer. I went to the contact centers and actually witnessed the process of signing a customer up for an audit or home energy assessment and what it looks like from both ends (the employee and the customer).


Also, during my internship I was able to go on an actual home energy assessment with the energy specialist, who was an employee of Mass Save (a partner of CSG). This gave me a perspective on what actually happens in the home energy assessments that CSG helps the utility companies design and implement. Additionally, I got to go to see the governor of Massachusetts, Deval Patrick, speak in Boston about his organization called Massachusetts Clean Energy Center (MassCEC). MassCEC “is dedicated to accelerating the success of clean energy technologies, companies and projects in Massachusetts—while creating high-quality jobs and long-term economic growth for the people of Massachusetts” ( This was a very enjoyable experience for me and made me feel good to know that my Massachusetts governor cares so much about helping to promote clean energies.

An environmental issue that CSG is attempting to mitigate is the rapidly growing rate of climate change. By promoting energy efficient practices and technologies, CSG is helping to reduce the amount of energy that our country is consuming. Since large amounts of energy in the U.S. are created from fossil fuels, when we use less energy we consume less fossil fuel and emit fewer damaging greenhouse gases into our atmosphere. Greenhouse gas emissions are the number one cause of climate change. By emitting less green house gases through the conservation of energy, we are in effect slowing down climate change. Not only is CSG helping to reduce climate change but they also are saving people money in the process because by using energy efficient technologies and practices in your home you also save money on your electricity bills, potentially saving thousands of dollars each year.

What I enjoyed the most about working for CSG was all of the wonderful and caring employees that made my internship experience so much more memorable and enjoyable. After working for CSG I really got the feeling that they cared about me as a person and wanted to help me succeed. Working with such friendly and caring people really made me feel comfortable working at CSG on a daily basis and made me actually want to work harder and do the best job possible in whatever is asked of me.
