Alan Rose, director of marketing for Intel's Energy and Utilities division, is investigating how data analysis in power grids and buildings can be used to drive new forms of energy savings. People constantly try to make small changes in their daily life to reduce the harm to the environment. Whether it is switched to work by bike, plug unplugged appliances or turn off faucets while brushing your teeth, these little things are actually improving the environment around us. The feedback from the data is also very encouraging: the average electricity consumption of American households in 2013 has dropped to the lowest level compared with 2001. At the same time, however, we often forget about our original intention of improving the environment during the frenzied debate on the topic of "How to do the most beneficial change for the environment". However, an unavoidable fact is putting people ahead of us. We urgently need to improve energy efficiency to reduce pollution and carbon emissions so as to meet the energy needs of a growing global population. Relevant projections show that from 2008 to 2035, global energy demand will increase by 53%. Half of the gap will occur in emerging economies like China and India. If we can meet all of these gaps through renewable energy, that would be fine; but today we still face a lot of challenges in the development of renewable energy. It is only a good idea to rely solely on renewable energy to meet the growing energy needs. Unfortunately, non-renewable fossil fuels, the main raw material used for energy production in today's society, are facing an increasingly dangerous drying-up. In the face of severe energy and environmental problems, we must start to seek change. While it is true that the subtle changes we make every day really relieve some of the pressure, at the same time we need to fundamentally change the way we produce, transport and consume energy through technological means. The emerging big data analytics technologies in all fields of the world in recent years will provide a steady stream of driving force for tomorrow's innovation and change. Today, power grids are becoming more intelligent throughout the world through modernization. The use of some of the latest technologies, including more accurate sensors, more rational billing solutions and more scientific management systems, has created a much more diverse set of data acquisitions that provide deeper insight into the operation and performance of the infrastructure . Such "smart grids" are continually generating very large-scale data related to energy consumption that is connected to various devices and systems to enhance their energy efficiency. For example, Intel is working with a local public utility in Germany to develop a smart substation monitoring system that requires less hardware than before and offers more security than before. First, this insight related to the production, transmission, distribution, and consumption of energy allows utilities to effectively manage the grid in near real-time. Being able to control the entire value chain from electricity production to consumption is a huge improvement for utilities. In addition, this will allow utilities to better predict electricity demand throughout the country and plan accordingly to better manage, more efficiently utilize valuable natural resources and inherent assets. It also enables utilities to quickly find fault locations in the network so that they can initiate a workaround to isolate faults, reduce the impact on the rest of the grid, and enhance the fault tolerance and stability of the grid itself. The National Institute of Standards and Technology predicts that by 2030, the new smart grid will save utilities $ 2 trillion in costs. In addition, information and communication technologies (ICTs) give us a more accurate understanding of the energy consumption process, helping utilities to customize more personalized tariff formats for different customers and provide more accurate billing. These services can all stimulate us to use energy resources more efficiently. For example, in order to ease operational pressure during grid peak hours, power suppliers can encourage users to lower tariffs during off-peak hours. These applications not only improve the cost and resource utilization efficiency, but also enhance the user experience. According to the ACEEE, the nation can reduce its energy consumption by 12% -22% if both home and business users can take advantage of existing information and communication technologies to bring improvements to the power system, which is equivalent to Save billions of dollars. The Pecan Street Institute in Texas, USA, has been working on smart grid and energy consumption research. Using the connection data for each individual household, the Institute obtained a perfect sample of household water savings. The Institute is also seeking support from volunteer families in Austin to research household energy use by getting data on their EVs, home appliances, running water, gas and solar energy consumption. The data provide an unprecedented example of household energy consumption, the largest database to date showing the consumption of energy and running water in homes. These data provide the basis for researchers to have a clearer understanding of the energy consumption of domestic homes and can use this data to help households save money by developing appropriate applications and new service models without affecting past lifestyles Resources and money. For example, to help households plan the most efficient layout of solar panels, notify homeowners when room temperature needs to be controlled, monitor tap water, gas and vent leaks, or measure nearby neighbors when problems occur with the operation of ventilation and air conditioning systems Electric peak to avoid tripping. The study, conducted by the Pecan Street Institute, will help utilities reduce stress and consumption on grid operations while reducing waste and cutting costs of gas and water services. While inter-device connectivity is key to this project, the emerging IoT technology can not be ignored as is the Pecan Street Institute and its volunteers used to track the carbon footprint near Texas. The Pecan Street Institute's project is an attempt to radically change the way people interact with energy, and this exploration will soon be extended to other states in the United States and across Europe. These energy-saving emission reduction insight into the radiation to the entire world will have a positive impact. Of course, privacy and security measures, as well as custom services, will also be integrated into the final product. By gathering insights, agencies will create the products and services that make for you, and economic policy opportunities to help you manage energy consumption in your home more easily and efficiently so that your family life will become More comfortable. With regard to environmental protection, our vision is usually focused on the trivial matter of turning off the faucet while brushing our teeth. In fact, technology can make our knowledge more open and allow us to view the issue of energy utilization at a macro level so that we can work together Maintain a better environment for generations to come.
