Cities around the world are looking for technology to make their cities smarter and more sustainable.
From smart grid, urban wind power generation, geothermal energy and intelligent lighting, modern cities are becoming greener, more interconnected, and aware of the importance of sustainable infrastructure for growth.
Singapore hopes to become the greenest city in the world, and will focus on smart lighting, pneumatic garbage collection and sensors to monitor the fallen elderly.
London was named the smartest city in Europe by the IESE Center for Globalization and Strategy, while Kansas City was named the smartest city in Europe by Missouri. -

Modern cities are becoming smarter and greener.
"Half the world's population lives in cities, with more than one million people moving to cities around the world every week.
In many places, this is an important part of the risk of prosperity, because urban areas are more likely to provide clean water, technology, employment and educational opportunities, "said Duncan Tait, corporate executive of Fujitsu in the United States and in Europe, the Middle East and Africa.
"It also provides challenges in housing, food systems and pollution.
With the growth of urban population, future cities will use digital technology to provide more effective services to meet these challenges.
"In 2017, London Mayor Sadik Khan announced that he hoped London would become the world's leading smart city and seek solutions and strategies from the scientific and technological community to improve London's public services and meet social and environmental challenges.
London, England, January 2017, the City of London recently announced that it will launch the Smart City Lighting Strategy through the City of London Company.
The strategy also includes long-distance lighting, which will complement the appearance of historic buildings, improve energy use and help to solve "square miles" of light pollution.
"London's lighting strategy will employ different types of technologies to install various lighting and light colors in urban space at different nights to balance the darkness of street and commercial lighting.
This strategy is a complement to urban lighting energy upgrading. -Savings and costs-efficient LED.
Research shows that night artificial lighting helps to increase light pollution globally.
This leads to the weakening of starlight in the night sky, the destruction of ecosystems, the reduction of biodiversity populations, and the possible impact on human health and sleep rhythm.
In 2013, the city of Paris passed a law requiring the front lighting of buildings to be closed before 1 a. m. to save energy.
Surveys of square miles show that some streets are overilluminated compared to the number of people actually using them, while current street lighting has little added value because nearby commercial lighting covers the entire area.
"As an innovative and particularly intensive corner of London, we must be smart, ambitious and open when considering new infrastructure," said Chris Hayward, chairman of the Planning and Transport Committee of London City Corporation.
"As urban occupiers become more diverse, 99% of urban enterprises are now small and medium-sized enterprises, 8% come from the technology, media and telecommunications industries, the streets of the city are constantly developing, and nighttime activities are expanding.
"Lighting strategies will support the night economy through safer, more sustainable and more attractive streets," Hayward said.
"This is an important opportunity for the city to become a model for London and the rest of the UK.
The strategy will also consider the key role of lighting in crime prevention and road safety, as well as addressing the needs of nocturnal animals in gardens and river areas, Hayward said.
The new remote control management system means that the city can change the time and lighting level remotely to achieve "intelligent" maintenance.
"Usually, for example, if a lantern is broken, we have to check it in person.
With the new system, we will automatically receive notifications about the location of electronic devices and the status of maintenance requirements, "Hayward said.
The city's smart lighting infrastructure currently does not include any sensors, but Hayward said it would be considered a road that would support remote management if the lights of a building had illuminated the street ahead.
"For example, we can judge that the streets around us are dimmed, and vice versa. . . If there are lighting problems in buildings, we will be able to adjust street lighting levels to help provide a safe environment, "added Hayward.
The London City Company said that the annual savings in energy and maintenance costs would ultimately exceed 500,000.
From Intelligent Lighting in London to Geothermal and Zero Lighting in Boise, Idaho-net-
Energy in Boise, Idaho-
Over the past decade, large emerging cities in the northwest have been working to make Boise a livable city.
Boise has a population of more than 220,000 in 2016 and covers an area of about 82 square miles.
Over the past decade, the city has also grown tremendously, and has continued to appear on "best" lists across the country, including the fastest growing city in the United States in 2018, which has the highest growth rate in the metro area of the United States, at 3. 08% in 2017.
Although Boise is as low-key as the United States, like London, it has set an ambitious goal of becoming the most livable city in the country.
In 2015, the city set energy-saving targets for urban buildings.
Through this process, they set a baseline for the future, with two main objectives.
New urban buildings will be zero-
By 2030, net energy and existing urban buildings will be reduced by 50% in the same year.
To achieve these two goals, the city built and operated a 20-mile-long southern farm, a 4225-mile-long farm. -
An acre zero net energy farm provides a variety of uses for the city.
This is also the first commercial zero. -
Haley Falconer, manager of Boise's Public Works Environment Department, said Idaho's net energy buildings.
Falconer was also appointed the city's first sustainable development coordinator in 2015.
"The whole farm is actually one of the greatest sustainability features we have," Harley said.
"Energy reduction and efficiency have long been Boise's priorities.
It is important to show leadership internally before the city enters the community for broader energy discussions and goal setting.
If you can find it in city operations, go for a walk, so that we can take it to a wider community.
"Farms extract all biological solids from municipal sewage treatment facilities.
These biological solids are then used as fertilizers to grow feed crops.
This is part of the renewal agenda for urban water resources. "This zero net energy farm is a great victory for the urban goal because it proves that it is feasible and gives us a learning experiment," Falcona said.
"This building has fallen into the net. -
Positive energy, which produces more energy than it uses. （30,000-kilowatt hours).
From various parts of the building to mechanical, lighting and plug loads, the building is monitored in various ways so that we can slice and slice the data in preparation for the next zero. -
We will have a road map for net energy construction and what works well.
Essentially, this building lays the foundation for our first goal.
"According to Falconer, in order to achieve the goal of energy conservation, the city has adopted a variety of ways to reduce energy use, including updating equipment, mainly the efficiency of HVAC, replacing lamps, implementing best energy-saving practices, and working with local utility companies to win awards.
Boise uses geothermal energy to heat more than 6 million square feet of downtown building space. About 90 buildings are the largest. -direct-
Use the system in the United States.
The building includes Boise High School.
YMCA City Center, Boise State University, Main Library, Boise Fort Community Center and Boise City Hall.
86% of the energy in all these buildings comes from geothermal energy.
Boise uses geothermal energy to offset carbon emissions by planting 275,000 trees a year.
"Since 2010, the energy consumption of major libraries has decreased by 45%, close to the 2030 target," Falcona added.
Falcona added: "We also see that Boise City Hall has cut energy by 38% since 2010, bringing it closer to the 2030 emission reduction target 10 years ahead of schedule. "
As part of the city's 2030 energy reduction target, they also launched renewable energy initiatives, including the use of solar energy in commercial and public buildings, including Boise Airport, 20-mile farms in the South and West City Hall.
Falcona says this applies to electric cars as well.
There are six electric cars and plugs in the city. -
Since 2016, hybrid vehicles.
By 2017, the city had reduced 622 pounds of emissions per year and saved the city an estimated $2,400 in annual fuel costs.
Boise has 43 charging stations for electric vehicles in 22 different locations.
"Our sustainable development is a triple bottom line -- community, economy and environment," said David Bitt, mayor of Boise.
"Maintaining green is important, but only if these changes become part of our community, how our local businesses prosper and grow, and how we protect the key elements that make Boise a special home.
"We are at a crossroads: we have to act selectively and use technology to lead us to prosperity, or we will face consequences," Tate said.
"In every major challenge we face, whether it is population ageing, sustainability or urbanization, we need to adopt a coordinated and considered approach to play the role of technology.
Tate added that because so many of the world's population live in urban areas, the concept of smart cities will be more important for urban planning.
