Energy costs account for a significant proportion of dairy farm overheads. Improving energy efficiency in these areas can enhance sustainability and reduce costs. The dairy community is committed to conserving natural resources and making progress, which is why they established the Net Zero Initiative (NZI). This is an industry-wide, on-farm effort that will play a key role in helping U.S. dairy continue to make progress toward becoming carbon neutral or better by 2050. Our mission at ProStar is to be a resource from the Ag industry in designing a solution to the high-energy demands of food production and processing.

Commercial & Industrial

The U.S. industrial sector accounts for more than 30% of the nation’s energy consumption. Not only does it consume 30% of our nation’s energy, but 30% of that energy is wasted in buildings. A recent survey from Frost & Sullivan reveals that electricity accounts for roughly 10% of overall operating costs, which can add up especially for organizations that have multiple locations. There are more than 4.7 million commercial buildings in the US that spend approximately $369 billion.

New construction allows for a whole new start and full-scale energy efficient operation to take place. By installation of the best lighting options, implementing an energy-efficient HVAC systems and solar could already cut the “supposed” energy load down by nearly half at the time. Commercial buildings use 70% of electricity and emit over 1/3 of the greenhouse gas emissions out there. With the proper design and construction plans of the facility as well as the mentioned energy-efficient technology, a new building can be way ahead of the curve in the present and fully prepared for what’s to come in the future. From a design phase thru Post-Construction phase, keeping in mind innovative structures as it harmonizes with the surrounding environment, there is no reason why sustainability shouldn’t be considered 10 out of 10 times.

Commercial Real Estate

Commercial real estate properties represent nearly 16 billion square feet of floorspace and consume more than 250 billion kWh of office building energy use. Office, warehouse and storage, and service buildings together account for nearly 50% of all commercial buildings and more than 40% of total commercial building floor space. In the energy economics of an average commercial real estate building, energy use is by far the largest operating expense, using roughly one-third of the entire operating budget. Furthermore, this usage accounts for about 20% of the nation’s annual greenhouse gas emissions.

Data Centers

Data centers are one of the most energy-intensive building types, consuming 10 to 50 times the energy per floor space of a typical commercial office building. Collectively, these spaces account for approximately 2% of the total U.S. electricity use, and as our country’s use of information technology grows, data center and server energy use is expected to grow too. Fortunately, there are many opportunities to reduce energy use in data centers.


Healthcare facilities use nearly 10% of the energy consumed by the commercial sector despite representing less than 5% of commercial floorspace, and the industry continues to grow. By being more energy efficient, hospitals around the country can save money, help prevent greenhouse gas emissions, improve the air quality of their communities, and support their commitment to public health. Hospitals protect their bottom line by being more energy efficient — every $1 a non-profit healthcare organization saves on energy is equivalent to generating $20 in new revenues for hospitals or $10 for medical offices. For-profit hospitals, medical offices, and nursing homes can raise their earnings per share a penny by reducing energy costs just 5 percent. By being more energy efficient and saving money, hospitals can reinvest savings from improved energy performance.

Higher Education

The higher education sector spends over $6 billion on annual energy costs. Colleges and Universities average spending is $1.28 per square foot on electricity and natural gas annually and with buildings being 10,000+ square feet, the bill adds up quick. When buildings are less efficient, they create a less sustainable environment and as well as a dicey financial situation. In campus buildings, which consume nearly 80% of all energy used by universities, improving the energy efficiency measures can cut overall energy up to 60%. Campuses typically have older buildings that rely on outdated equipment; universities can use their funds to improve the buildings performance as a whole, especially when it comes to the adoption of energy efficient technology. Not only can you save money by becoming more energy efficient, but this will save energy and take less strain off the grid as well as improve a campus’s carbon footprint by demonstrating environmental leadership.


The Retail, Food Service, and Grocery sectors spend over $41 billion on energy costs a year. Energy is the fourth largest in-store operating cost for US retailers (after labor, rent and marketing). A typical hypermarket may have energy bills of $500,000 per year, for example. While overall energy costs differ by type of retail format—between about 4 and 9 percent of in-store operating costs—they also vary widely between stores of the same age, type and size. That suggests a significant opportunity for cost reduction. When retailers conduct energy audits on their stores, they typically identify opportunities to reduce energy consumption by 20 to 30 percent, and sometimes by up to 50 percent.
