Green computing, the study and practice of efficient and eco-friendly computing resources, is now under the attention of not only environmental organizations, but also businesses from other industries. In recent years, companies in the computer industry have come to realize that going green is in their best interest, both in terms of public relations and reduced costs. This article will take a look at several green initiatives currently under way in the computer industry, as well as issues that have been raised regarding these initiatives. We will also have a talk with VIA to learn more about the future of green computing.

The huge amount of computing manufactured worldwide has a direct impact on environment issues, and scientists are conducting numerous studies in order to reduce the negative impact of computing technology on our natural resources. Companies are addressing e-waste by offering take-back recycling programs and other solutions, with lower energy consumption and less wasted hardware. A central point of research is testing and applying alternative nonhazardous materials in the products’ manufacturing process. VIA Technologies Green ComputingVIA Technologies, a Taiwanese company that manufactures motherboard chipsets, CPUs, and other computer hardware, introduced its initiative for "green computing" in 2001. With this green vision, the company has been focusing on power efficiency throughout the design and manufacturing process of its products. Its environmentally friendly products are manufactured using a range of clean-computing strategies, and the company is striving to educate markets on the benefits of green computing for the sake of the environment, as well as productivity and overall user experience. Carbon-free computing
In addition, VIA promotes the use of such alternative energy sources as solar power, so power plants wouldn't need to burn as much fossil fuels, reducing the amount of energy used. Wetlands also provide a great service in sequestering some of the carbon dioxide emitted into the atmosphere. Although they make up only 4 to 6 percent of the Earth's landmass, wetlands are capable of absorbing 20 to 25 percent of the atmospheric carbon dioxide. VIA is working closely with organizations responsible for preserving wetlands and other natural habitats, and others who support extensive recycling programs for ICT equipment. The amount paid to these organizations will be represented by a proportion of the carbon-free product’s price. Carbon-emissions control has been a key issue for many companies who have expressed a firm commitment to sustainability. Dell is a good example of a company with a green image, known for its free worldwide product-recycling program. Dell’s Plant a Tree for Me project allows customers to offset their carbon emissions by paying an extra $2 to $4, depending on the product purchased. AMD, a global microprocessor manufacturer, is also working toward reducing energy consumption in its products, cutting back on hazardous waste and reducing its eco-impact. The company’s use of silicon-on-insulator (SOI) technology in its manufacturing, and strained silicon capping films on transistors (known as “dual stress liner” technology), have contributed to reduced power consumption in its products. Solar Computing
Lead-Free and RoHS computing
In February 2003, the European Union adopted the Restriction of Hazardous Substances Directive (RoHS). The legislation restricts the use of six hazardous materials in the manufacture of various types of electronic and electrical equipment. The directive is closely linked with the Waste Electrical and Electronic Equipment Directive (WEEE), which sets collection, recycling, and recovery targets for electrical goods and is part of a legislative initiative that aims to reduce the huge amounts of toxic e-waste. Driven by these directives, VIA implemented a set of internal regulations in order to develop products that are compliant with these accepted policies, including the use of nonhazardous materials in its production of chipsets, processors, and companion chips. In 2001, they focused on lead-free manufacturing, introducing the Enhanced Ball Grid Array (EBGA) package for power efficient VIA processors and the Heat Sink Ball Grid Array (HSBGA) package for their chipsets. In traditional manufacturing processes, lead is used to attach the silicon core to the inside of the package and to facilitate integration onto the motherboard through tiny solder balls on the underside of the package. VIA's lead-free manufacturing technologies do not require a lead bead, and the solder balls now consist of a tin, silver, and copper composite. However, not everyone is satisfied with this new objective. Howard Johnson of the online EDN magazine says that the move toward lead-free devices is not only unhelpful but actually worse for the environment. “The additional tin mining required to produce high-purity tin alloys, plus the mining of other precious metals required to alloy with tin in substitution for lead, is a poor trade for the use of existing lead, much of which comes from recycled products,” Johnson writes. He also believes that lead-free assembly is less reliable than lead-based assembly, partially due to the increased growth of tin whiskers — small, hair-like metallic growths that naturally emerge from the surface of solid tin. On lead-free tin surfaces, these whiskers can grow to a length sufficient to short an electronic circuit to another, leading to product failure. Energy-efficient computing
A central goal of VIA’s green-computing initiative is the development of energy-efficient platforms for low-power, small-form-factor (SFF) computing devices. In 2005, the company introduced the VIA C7-M and VIA C7 processors that have a maximum power consumption of 20W at 2.0GHz and an average power consumption of 1W. These energy-efficient processors produce over four times less carbon during their operation and can be efficiently embedded in solar-powered devices. VIA isn’t the only company to address environmental concerns: Intel, the world's largest semiconductor maker, revealed eco-friendly products at a recent conference in London. The company uses virtualization software, a technique that enables Intel to combine several physical systems into a virtual machine that runs on a single, powerful base system, thus significantly reducing power consumption. Earlier this year, Intel joined Google, Microsoft, and other companies in the launch of the Climate Savers Computing Initiative that commits businesses to meet the Environmental Protection Agency’s Energy Star guidelines for energy-efficient devices. Kevin Fisher, Intel’s EU standards director, says that while the company is dedicated to its green-computing plans, it is important to not blame the IT industry alone for carbon emissions worldwide. He argues that the industry also helps in saving huge amounts of power due to the Internet, enabling, for example, online shopping and billing. Governments go green
Worldwide, standby power is estimated to account for as much as 1 percent of global greenhouse emissions. Most of the energy used by products on standby does not result any useful function. A small amount can be needed for maintaining memory or an internal clock, remote-control activation, or other features; but most standby power is wasted energy. Energy Star–enabled products minimize this waste. In 1998, the China National Development and Reform Commission (NDRC) founded the China Energy Conservation Program (CECP), a nonprofit organization in charge of the administration, management, and implementation of the certification for energy- conserving, water-saving, and environmentally friendly products. CECP is dedicated to encouraging manufacturers to produce more resource-efficient products and help consumers make more sustainable purchase decisions. CECP undertakes various projects within the national and the international arena, actively supporting improvements in energy efficiency and environmental protection and assisting social and economic sustainable development. In Japan, the Energy Conservation Center is responsible for raising public awareness on energy conservation, training and state examinations for energy managers, and their energy-conservation campaign and exhibition (ENEX). On the horizonGreen technology is gaining more and more public attention through the work of environmental organizations and government initiatives. VIA is one of the first corporations to concentrate on green computing that seems less a passing trend than a first step toward significant changes in technology. In May 2007, IBM unveiled its Project Big Green, dedicated to increasing energy efficiency across the company's branches around the world. Experts say that businesses will continue to invest in clean computing, not only because of future regulations, policies, and social demands to reduce their carbon footprint, but also due to the significant long-term savings it can make.
Another American company, Everex, has released the Impact GC3502, a green PC that uses 20W of power, owing to a 1.5GHz VIA C7-D processor. VIA: vision through the pc-1 initiativeVIA isn’t focusing only on the technological aspects of its eco-friendly devices, it’s also taking a look at their applications. The VIA pc-1 initiative seeks to enable the next 1 billion people to get connected, by providing wider access to computing and communications technologies. The company is concentrating on empowering new, emerging markets, looking at models that reach beyond individual ownership of a PC, such as local pay-for-use facilities. Products built for such a use are characterized by ultra-efficient energy consumption and the ability to withstand heat and dust in harsh environments. In VIA’s own words: "Pc-1 brings together business ingenuity with corporate responsibility and altruism. Helping to build skills and literacy throughout the world and incorporating and preserving cultural content are goals now within our grasp. Information is the oxygen to nurturing social mobility, economic equality and development, and global democracy. Providing not just the tools and the know-how, but the support and the maintenance, is all part of what makes pc-1 the next generation of information technology, the next generation of global development". Among the company’s projects under the pc-1 program are the “tuXlab” computer center in South Africa and an ICT Training Center in Vietnam. Green Interview with VIATFOT recently interviewed Gaynor de Wit, deputy director of processor platform marketing at VIA Technologies, to learn more about the company’s green-technology initiative and future plans. Q: Can you describe when and why VIA decided to “go green”? Since the introduction of the VIA C3 processor in 2001, we have led the industry in the design of energy-efficient x86 platforms. From thin clients to laptops to industrial computing systems, VIA processor platforms have built a reputation for leading performance per watt and cool operation. With the challenges presented by the forward-thinking European Union directives on the Restriction of Hazardous Substances (RoHS) and Waste Electrical and Electronic Equipment (WEEE), VIA implemented internal procedures that ensured a smooth transition for the development of RoHS-compliant products. While the RoHS directive came into effect in July 2006, VIA’s move toward lead-free manufacturing started much earlier, with the introduction of the Enhanced Ball Grid Array (EBGA) package for its processors and the Heat Sink Ball Grid Array (HSBGA) package for its chipsets. In fact, VIA has been shipping lead-free VIA Eden and C3 processor platforms into the market since the end of 2003, with the current VIA C7 processor family lead-free at launch in 2005. With the launch of the VIA C7-D processor in late 2006, we’re seeking to define a new era in eco-friendly computing, and to further heighten awareness of computing’s impact on the environment. Conceived as the ideal desktop processor for corporations seeking to significantly save on their power bills, while delivering the performance and reliability needed for productivity applications, the VIA C7-D processor is the world's first computer component to be sold as carbon-free. Q: Does green computing reduce costs for VIA in the short term as well as the long? And the savings don’t stop at lower power consumption through more efficient components. Cooler-running systems don’t heat up office spaces to the same extent, enabling significant air-conditioning cost reductions. Additionally, cooler components extend the useful life of hardware, further reducing costs. The business case for saving energy is very clear. But green computing extends out of the data center and the desktop, encompassingsuchmobility issues as encouraging work from home and video conferencing that discourages travel. VIA is a global organization of nearly 3000 people, with engineering teams needing to collaborate regularly, so there are significant financial savings as well as lower carbon emissions that can had through reduced travel. As technology improves, that’s been easier to achieve, and to this end we have an in-house videoconferencing suite that has gone a long way toward cutting back on costs. Q: What obstacles do you face, in research or development, with your environment-friendly products? On the design side, ensuring energy efficiency in IC chips requires a keen focus on reducing voltage, while retaining performance and enabling our signature rich-feature integration within ever-smaller packages. This is not a simple process and demands high levels of skilled engineering, which is why, to this day, we can offer the lowest power-consuming embedded, notebook, and desktop processors in the world. Achieving such high levels of energy efficiency and low heat production also allows us to build smaller, which in turn allows our partners to build smaller systems, providing savings for consumers not only in terms of power requirements but also in disposal costs. For portable systems, such as the new generation of ultra-mobile devices, this also means longer battery life, an essential element of ultra-mobility Other companies cannot achieve this, as their chips consume too much power and emit too much heat. On the manufacturing side, the removal of hazardous substances raises several technical challenges, especially the replacement of lead as a stable solder substance. However, an aggressive approach to the problem, starting five to six years ago, allowed our engineers the time to experiment with effective replacement alloys, so that our processor platforms were effectively manufactured lead-free long before the industry was mandated to do so. Q: How would you respond to critics who claim that lead-free products are dangerous and unreliable? The fact is, lead-free components and manufacturing processes can be completely safe and reliable. VIA, and other companies who have been lead-free for a while, are in a good position, because we have already worked through the transition problems. Everyone else is just going through it now, which is why we’re hearing so much about it. Not all lead-free soldering is the same. Some alloys are better than others, and some temperatures work better than others. For many companies, there will be an element of trial and error in discovering what works best for them. Certainly, we’ve seen real advances in the last few years with some electronics manufacturers offering lead-free soldering that rivals their leaded counterparts in reliability. We feel comfortable that criticism will die away as companies progress through the transition, and this is being borne out already by the European Union’s removal of several of the exemptions to the RoHS directive. Q: How do you see VIA's green-initiative progress in the future? We’ll also continue to work closely with organizations and companies involved with renewable energies in an effort to develop more sustainable computing platforms. At VIA, we believe that the computing device you’ll be using in the future will be very different from the one you’re using today. Devices are using less and less power at the same time as renewable energy is getting more and more portable and effective. The materials computers are made from are becoming less hazardous. At the end of the road will be a computer that not only connects us to the world through information technology using renewable energy, but is also constructed through a cycle of manufacturing that doesn't hurt us or future generations. How long that road is isn’t clear at the moment, but VIA intends to continue to lead the way forward through its green-computing initiative. |
