Process Improvement
consumption dropped during this time period, as a result of activities such as closing the Shreveport, LA, vehicle assem- bly plant and the steam elimination project at the Orion, MI, vehicle assembly plant, which led to the decreased number. However, through efforts such as evaluating cogeneration options for using landfill gas and exploring additional solar power opportunities (including a 3-MW solar project at the Changwon Assembly Plant in South Korea, announced in December 2012), progress against these metrics remains consistent with our projected glide path toward reaching our 2020 manufacturing commitments.
Star Power GM’s record in manufacturing energy and emissions
reduction has been underscored by being named as 2013 Energy Star Partner of the Year—Sustained Excellence, for energy management by the US Environmental Protection Agency (EPA). It is the highest designation a corporation can receive. We also increased the number of facilities that meet the EPA’s Energy Star Challenge for Industry from 30 to 54 in 2012. All 54 plants, on average, reduced their energy usage by 26%, which represents enough savings to power a city the size of New Orleans for a year. GM has a total of eight Energy Star-labeled buildings and plants for superior energy efficiency from the EPA: two assembly plants, five warehouses, and one office building. Te most recent EPA-certified site is its Lansing (MI) Customer Care and Aſtersales parts distribution center, which generates 35% fewer greenhouse gas emissions and uses 35% less energy than similar buildings in the US. Many of the most recent energy-savings initiatives have been within GM International Operations (GMIO) in China, India,
to the implementation of 63 ideas as part of a company-wide campaign to reduce peak usage of electricity in the winter.
Renewable Energy Renewable sources comprise a significant part of GM’s
manufacturing energy strategy. Today, we are the number-one automotive user of solar power in the US and have 30 MW of solar power installed across our global facilities. By the end of 2015, we expect to double solar output, putting GM well on its way to installing a total capacity of 125 MW of renewable energy by 2020. Solar power enables us to grow our business while decreas-
ing our carbon footprint and minimizing the risks associated with energy-related volatility. Tough the business case for solar depends upon a long-term commitment and incentives, GM’s consumption of renewable energy is helping to spur growth for a solar industry still in its infancy and will help solar move toward grid parity—the point when the price of an alternative energy source becomes less than or equal to the cost of purchasing power from the grid. During the past year, we became a member of the Solar Energy Industries Association to further demonstrate our support for the US solar industry. GM’s newest US solar installation is a 1.2-MW rooſtop
solar array on top of the Toledo Transmission facility, which powers 3% of the electric consumption at the facility. In 2012, as was mentioned earlier, we also announced a solar instal- lation at our Changwon Assembly Plant in South Korea, the home of the Chevrolet Spark and Spark EV. Tis array will provide the equivalent energy used by 1200 homes in South Korea in one year. Te 3-MW installation will cut carbon emissions by 2400 t annually.
GM is one of 13 Fortune 100 companies to set commitments for both renewable energy and greenhouse gas (GHG) reduction.
Kenya, Russia, South Africa, South Korea and Tailand. Te latest data shows that GMIO’s average total energy usage is 1.14 MW-hr per vehicle, less than half the industry average of 2.37 MW-hr per vehicle. Te ability to achieve these savings demonstrates how
energy efficiency has become a standard aspect of GM’s manufacturing processes and culture. Investments in equip- ment upgrades, such as lighting, ventilation system controls and automatic shutoffs, are made annually, and projects with a hurdle rate of one year or less are implemented automatically. In addition, plant performance evaluations include energy use per production unit for every site, and employees who suggest an improvement to an existing process can receive a portion of the implemented savings up to $20,000. During the past year, GM Korea held cross-functional energy workshops that led
56 Motorized Vehicle Manufacturing Solar power is only one of a diverse portfolio of renewable
energy sources for GM. In total, we use more than 62 MW of renewable energy across our global facilities. We are one of the largest users of landfill gas in the US, where three of our facilities combined generate more than 20 MW of renewable energy from landfill gas. And at our GM do Brazil manufac- turing facilities, we procure more than 15 MW of biomass- generated electricity from sugar cane.
Dealing with Water Hazards Tere is no shortage of statistics to underscore the world’s
growing concern over water scarcity. Te issue affects more than 1.2 billion people today, and water stress is expected to be an issue for two-thirds of the world’s population by 2025. Global leaders attending this year’s World Economic Forum
