Going Green, How To Make It Pay Off
With 22% of the globe? s energy consumption, the US is the largest energy consumer and lowest energy producer of any developed economy in the world. The result? It is the most CO2 intensive nation in the world with a daily consumption of 6 gallons of oil per person per day or 19 tons of carbon dioxide per capita annually. This is 80% higher than Europe and 94% higher than Japan. The greatest sources of US energy expenditure are: 16% Commercial buildings21% Residential energy consumption25% Road transportation35% Industrial Energy (chemicals, steel, processing etc)Over the next decade, those sectors of the economy driven by consumer demand are the ones which will most rapidly increase greenhouse gases - buildings and houses. The good news is that there are multiple opportunities to improve upon these areas. For example, the demand for energy could be reduced by 25 to 30% through a series of low cost, high return steps:? Equipment replacement, [link widoczny dla zalogowanych]sing high-efficiency water heaters and Energy StarTM appliances when it? s time for new. These seemingly small steps save energy and reward investment with a rapid payback of less than 2 years, although many are immediate and some actually pay for themselves instantaneously.? Replacement of incandescent bulbs with compact florescent lighting.? Monitor & control of energy consumption specifically heating and cooling in homes and buildings? Smart Grid. In fact, according to the McKinsey Report? Reducing U. S. Greenhouse Gas Emissions: How Much What Cost? 40% of the total options for reducing greenhouse gases do not cost, rather releases money into the economy. As the recognition not only of the costs of global warming,[link widoczny dla zalogowanych], but also the savings to be realized with replacement and upgrading, become apparent,[link widoczny dla zalogowanych], opportunities abound,[link widoczny dla zalogowanych]! There are numerous initiatives and programs supporting environmentally friendly products and solutions which continue to unfold at a breakneck pace. These initiatives are for products designed to be manufactured using greener processes and handled responsibly at the end of their life cycle as well as those specifically designed to aid industries and individuals in reducing their carbon footprint. Products such as Western Digital? s GreenPower hard drives and Siemens hybrid drive system for buses reduce energy consumption and CO2 emissions up to 40 percent. Both were developed under green initiatives and are taking their industries by storm. Wireless NetworksCompanies can greatly reduce energy consumption, which, in turn, reduces cash outlay, by switching to wireless networks. Industries everywhere are finding ways to save not only on energy and its costs but through the use of wireless networks, in numerous other ways too. According to Oak Ridge National Laboratories, through the use of wireless sensor networks, savings on energy for motors used in industrial processes could improve efficiency by 20%, resulting in significant cost savings. Wayne Manges said: "With electric motor-driven systems accounting for nearly one-fourth of all electricity consumption in the United States, the potential for savings is huge. "The Department of Energy? s Industrial Technologies Program works with US industry to improve environmental performance and energy efficiency. The ITP is distributing 15 million to support R& D specifically to improve energy efficiency in industrial processes. Already a number of new wireless sensor products are being developed together with the Department of Energy. Cost savings with wireless systems are recognized in multiple areas including materials and labor where the cost of running wire in plants ranges between $155 and $3, 700 per foot. The typical payback for wired systems is 24 months and less than a quarter of that for a wireless equivalent, only six months. Add in the on-going energy savings and the return on investment decision is very clear. In a large number of industries,[link widoczny dla zalogowanych], companies are recasting their product lines to implement wireless technologies. "We can't think of any segment of the industry that isn't going to be impacted by this, " states Honeywell? s CTO Dan Shiflin. Wireless sensor networks of all varieties are exploding into our world. There is a massive amount of research & development, from academia to start-ups, pushing to create proverbial? better-faster-cheaper? products. A growing number of products are based on an emerging specification? ZigBee?. A majority of utility companies that have settled on a standard have identified ZigBee as their preference due in main to its inherent security capabilities. Real-time data from wireless sensors networks will enable companies to achieve greater productivity and efficiency by continually improving their processes. Many businesses have adapted their strategies to have the smallest degree of impact on the environment. They are upgrading their businesses to operate more efficiently and conserve resources while retaining economic feasibility by using smart grid and wireless technologies. The perception that green technology is expensive is a common misconception. When you use smarter simpler products with better resource utilization, you not only preserve precious resources, it is less expensive. Named BP International's first Director of Technology & Sensory Networks, for the oil company's Technology Office, Ken Douglas said "You don't ask people 'How would you use ZigBee? ' Because they don't know, but if you ask them: 'How would you use information that you can now access for the first time? ' They have to think about it for a bit, but then the ideas just starting pouring out. "In addition to the benefits of ZigBee? s security layers, the mesh network is highly reliable, flexible and can connect a variety of sensors simultaneously including protocols such as OPC, Modbus and HART. Companies whose product objectives include reducing costs or waste, more reliable equipment management; improved physical asset control or greater situational awareness should investigate the variety of capabilities wireless sensor systems can provide. In addition to the potential savings in energy, there are likely many additional cash benefits to be found.Topics related articles：
