The following is a brief overview of energy demand solutions undertaken by members of C2ES's Business Environmental Leadership Council (BELC).

For more information on each of these companies efforts to address climate change, please see the Businesses Leading The Way section of this Web site.


Air Products and Chemicals

  • Air Products and Chemicals’ efficiency engineers constantly monitor the performance of their major energy-intensive operations. In 2002, those engineers completed numerous global energy efficiency projects resulting in an estimated 26 MW of power savings; this is equivalent to the power consumed by 18,500 average homes annually and equivalent to avoiding 174,000 tons of CO2 emissions.
  • Air Products works closely with its energy suppliers to make the most efficient use of their generation facilities to help them minimize their greenhouse (GHG) emissions. Air Products matches its energy needs to that of the energy supplier by shutting down production at times of peak demand and increasing production at other times. Such efforts contribute to "demand loading," a practice in which energy suppliers try to optimize the generational efficiency of a power plant by ensuring that it runs as close as possible to the point of maximum efficiency.
  • Air Products is working with the DOE’s Vision 21 Program and other business partners on the development of Ion Transport Membrane (ITM) Oxygen technology. Many emerging energy-production technologies, environmental cleanup technologies and industrial processes would benefit from using oxygen in place of air.
  • Air Products and Chemicals and its partners were selected by the DOE Industries of the Future (IOF) Best Practices Program to demonstrate the potential for using CO2 to manufacture polyurethane. In addition to using less energy, the new process will be cleaner, significantly reduce the environmental impact of making the foam, and reduce the net release of CO2.


  • Alcoa has reduced the electricity required to produce a ton of aluminum by 7.5% percent over the last 20 years.
  • Alcoa supplies lightweight, recyclable materials for motor vehicle assembly; each kilogram of aluminum that replaces higher density materials provides the potential to save 20 kilograms of CO2e emissions via better fuel economy and recyclability.

American Water

  • Although lighting accounts for less than one-half of one percent of American Water’s electricity use, facilities are incorporating high efficiency lighting technology to reduce energy use.
  • In Pennsylvania, American Water is piloting a technology that allows its large energy consuming sites to reduce their electric consumption during peak events or times of energy usage. This "demand management" technology will avoid the need for additional power generation and reduce energy costs for its customers.

Cummins Inc.

  • Cummins has implemented energy conservation efforts in several of its facilities. Corporate headquarters and other major facilities have agreed to cut electricity consumption by 6 MW on peak demand days. Other facilities have installed air compressor controls and high-efficiency lighting, and have begun using hot water from engine testing to melt snow, reducing the need for electric resistance wiring.

Delta Air Lines, Inc.

  • Delta has replaced over 380,000 square feet of roof at Delta’s Technical Operations Center in Atlanta with white thermoplastic polyolefin roofing material. The reflective properties of this material reduce the use of energy for building heating and cooling. As a result of this installation, Delta saved over 165,000 kWh of annual energy use. In 2011, another $2.8 million will be invested in this eco-friendly roofing material at Delta’s Technical Operations Center.
  • An effort to reduce the use of electricity at Delta’s Technical Operations Center included the replacement of lighting fixtures in two hangars. Annual energy savings associated with this project total 1,802 metric tons of CO2 —equivalent to the annual emissions of 355 passenger vehicles.
  • In 2010, Dominion installed more than 30,000 smart meters and related technology in four Northern Virginia localities, bringing total installations in Virginia to about 100,000. These initial installations lay a foundation for more fully understanding the costs and benefits of smart meter technology as the company assesses its potential for reducing customers’ energy usage and improving grid reliability.
  • At Dominion East Ohio, the company is investing $9.5 million a year in demand-side management (DSM) programs for its Ohio customers. Of that annual total, $6.5 million is funding home weatherization programs for qualified low-income customers, administered by the Cleveland Housing Network.
  • Dominion also created a DSM Collaborative, comprised of Dominion East Ohio, the Staff of the Public Utilities Commission of Ohio, consumer advocates and other interested stakeholders. Based on DSM Collaborative input, we are investing $3 million a year towards a residential retrofit program called "Home Performance with Energy Star."
  • Dominion maintains four voluntary energy efficiency and conservation programs that are expected to save our customers an estimated $290 million over the next 15 years. There are two residential programs and two commercial programs. These offerings are also expected to provide significant environmental benefits and help Dominion meet the state of Virginia’s voluntary 10 percent energy conservation goal by 2022.
    • Smart Cooling Rewards: Customers receive $40 annually for letting Dominion cycle on and off their air conditioner or heat pump system during periods of high demand.
    • Home Energy Improvement Program: A free in-home energy audit and improvement program for income-qualified customers, where an energy specialist will examine a customer's home, generate a custom audit report and complete energy efficiency improvements.
    • HVAC Rewards: Customers who replace their HVAC system or install a new HVAC system with one that has a higher efficiency rating than the current national minimum requirements receive a rebate for part of the price of the system, based on a per ton rate.
    • Lighting Rewards: Customers who retrofit existing lighting with more efficient lighting receive a rebate based on a per fixture rate. 
Dow Chemical Company
  • Since 1994 Dow has saved $9.2 billion and 1700 trillion BTUs due to improved energy intensity.
  • Dow has initiated 40 energy efficiency projects at facilities in the U.S., Germany, Spain, France and The Netherlands that are anticipated to save approximately 8 trillion BTUs of energy and reduce CO2 emission by more than 400,000 metric tons. Selected for their ability to reduce energy use and GHG emissions, as well as accelerated energy cost savings, these projects are sponsored with $84 million from the Energy Intensity Improvement Fund and demonstrate Dow’s expertise in developing energy efficiency innovations to achieve environmental effectiveness and economic efficiency.
  • In the fall of 2009, Cobblestone Homes approached The Dow Chemical Company about partnering on a net-zero energy home. The company embraced the concept and Vision Zero was born. Throughout the next six months, the two companies worked together to develop plans and select technologies that would insulate and seal the building envelope as well as generate renewable energy.

DTE Energy

  • DTE Energy works with customers to find ways they can help protect the environment by using energy wisely. DTE Energy Partnership has a staff of more than 40 energy engineers that work with businesses to increase efficiency.

Duke Energy

  • Duke Energy seeks to reduce customer energy consumption by 2500 GW and peak demand by 2,100 MW by 2013
  • Duke Energy received regulatory approval to implement the smart grid in Ohio in 2008 and began full-scale deployment in 2010. of the technology. Duke Energy has installed approximately 140,000 smart electric meters, 100,000 smart gas meters, and 22,000 communication nodes in Ohio — eliminating the need for manual meter readings and giving customers greater insight into their daily energy usage.
  • Duke Energy is conducting a pilot Smart Grid program in Indiana and expects a ruling about the future of the program from the Indiana Utility Regulatory Commission (IURC) in July 2011.
  • Beginning in 2011, Duke Energy's Residential Smart Saver will give Kentucky residents incentives of as much as $250 to cover part of the cost of items like air sealing, attic insulation, duct sealing, and tuneups for air conditioning and heat pumps. The incentives also will be available for the installation of high-efficiency heat pumps or air conditioners in homes. The program won't have income limits. Instead of the incentives, Duke will provide direct installation of energy efficiency options for low-income customers.
  • Duke's various programs also include energy audits, energy bill assistance and financial incentives to customers who let the utility remotely turn off their air conditioners during peak usage times in the summer months.


  • DuPont used seven percent less total energy in 2004 than it did in 1990, despite an almost 30 percent increase in production. Compared to a linear increase in energy with production, this achievement has resulted in $2 billion in cumulative energy savings.
  • DuPont Tyvek housewrap improves the energy efficiency of buildings, with energy savings in the first year of use alone some 10-20 times the energy required to produce the product.
  • DuPont’ engineering polymers in applications like intake manifolds help to safely reduce the weight of motor vehicles and improve their fuel efficiency.


  • As of June 2011, Entergy's pilot program SmartView has provided 2,500 New Orleans residents with "smart meters" to provide real-time updates on their power use.

  • Entery deploys energy efficiency/Demand Side Management programs throughout Entergy's service territory. Currently there are 25 EE/DSM programs that cover all customer classes (residential, commercial and industrial). Recognizing the powerful benefits associated with energy efficiency, Entergy created an Energy Efficiency Task Force to identify initiatives that can reduce systemwide energy demand by a goal of 300 megawatts.

  • Entergy, under its commitment to stabilize power plant CO2 emissions, has implemented 44 internal GHG reduction programs as of December 2003 that will achieve a projected 1 million tons of CO2 equivalent reduction by 2005. Several of these projects focus on using less fuel to generate electricity at power plants: two projects allow generating units to operate on less power when in stand-by mode, while two other projects are installing advanced controls to regulate the combustion processes in selected plant boilers. These projects are dedicated to improving the efficiency and capacity factor of Entergy’s cleanest and lowest emitting fossil, nuclear, and renewable electric generating units.


  • Exelon Energy Delivery’s Smart Returns Load Reduction Programs
    • ComEd’s 10 Smart Returns products represent one of the largest, most successful loads response portfolios in the United States. The programs provide customers with a financial incentive to curtail use, while benefiting the community and the environment through a lower, more stable load. The more customers curtail use, the more financial incentives they can potentially earn.
    • From single-family residential homes to large steel mills, the Smart Returns products provide opportunities for almost every customer to participate. ComEd works closely with large commercial, institutional and industrial customers to customize curtailment plans and maximize energy efficiency opportunities. On hot summer days, ComEd’s load response programs can contribute a 1,000-MW reduction to system peak loads.
    • PECO’s Smart Returns program has three products, and customers may participate in any or all. The first, active load management (ALM), is a program in which participating customers guarantee that they will reduce their energy consumption within one hour of PECO’s request. This emergency program is designed to respond to events that are triggered within the PJM Interconnection, a regional transmission organization. During 2004, PECO gained 26 MW of new ALM customer load, in addition to the existing 74 MW under contract.
    • Under the second Smart Returns program, voluntary load reduction, customers receive a one-hour notification to curtail energy consumption and share in a percentage of PECO’s energy cost savings. PECO had 123 MW under this program for 2004.
    • Finally, PJM’s voluntary Economic and Emergency Load Response Programs provide an additional Smart Returns choice for potential load response customers. During 2004, PECO signed up more than 200 MW.
  • EED internal energy efficiency initiative
    • The Exelon Environmental Strategy Energy Efficiency Team was charged with the goals of improving energy efficiency at EED facilities by 3 percent annually from 2003–2007 and developing recommendations for expanding the program to other Exelon facilities. The team, which supports 74 EED facilities and 8,200 employees, implemented a broad strategy that includes a budget for collateral materials, facility benchmarking and energy audits, efficiency retrofits and a multiyear communications plan with internal articles, posters and stickers to remind employees to turn off computers and lights when not in use.
    • For 2004, EED reduced energy consumption by 7 million kilowatt hours (kWh) compared to the 2002 baseline. Normalizing the data based on 30-year averages and the current year heating and cooling degree-days resulted in an improvement of 4 percent in 2003 and 3.8 percent in 2004, thus exceeding the goal each year.
    • Currently, there is a focus within Exelon Nuclear to identify energy efficiency opportunities.
  • Green corporate headquarters
    • In 2004, Exelon’s Real Estate and Facilities business unit initiated the consolidation of our three downtown Chicago locations into a single flagship headquarters. We believe that greater cross-collaboration between functions can achieve synergies that will improve productivity. The new headquarters will contribute toward reducing our real estate costs.
    • We will demonstrate our environmental stewardship by incorporating sustainable design and building practices into the headquarters’ design. The U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) program defines the parameters for building and operating new and existing buildings to be more environmentally friendly. In determining whether Exelon could participate in the LEED program without incurring an unreasonable cost premium, we recognized that the building and design marketplace has evolved to a point where the new headquarters can incorporate many established and forward-thinking elements of sustainable design and construction. The costs associated with sustainable design are now on a par with typical building materials and processes. We are confident that the new headquarters will be an inviting, innovative and practical space for our employees and visitors for years to come.
  • EED support of Chicago Green City goal
    • The Exelon Marketing Technical Services (MTS) team actively supports Chicago’s efforts to make the city the greenest community in the United States. Exelon’s support ranges from energy efficiency work in city facilities to efficiency improvements in industrial facilities and sustainable design outreach.
    • Retrofits in city facilities. In 2004, MTS conducted a benchmark study evaluating energy efficiency opportunities such as lighting retrofits and solar domestic water heating for the city’s firehouses. Exelon also completed lighting retrofits at several Chicago Transit Authority and City Colleges of Chicago facilities, including bus garages, repair shops, classrooms, laboratories, gymnasiums and swimming pools. In aggregate, the projects saved more than 1,500 kW in installed lighting load, 9.6 million kWh in annual electricity consumption and 20.5 million pounds of CO2 emissions.
    • Saving energy, avoiding emissions and improving Chicago’s economy. In conjunction with the University of Illinois and the city’s Department of Environment, MTS supports and coordinates Chicago’s Industrial Rebuild Program targeted to specific industrial segments. In 2004, ComEd completed assessments of chemical manufacturers and continued assessments of confectionery companies. These efforts identified potential annual savings of 3.7 million kWh and 14.5 million cubic feet of water and avoidance of 5.5 million pounds of CO2 emissions.
