10 Top Smart Cities of the world

The world’s urban population is expected to double by 2050 as more and more people move into cities every day. Over the next 20 years, the equivalent of 7 cities with more than 10 million people will be added every year. This has placed a lot of pressure on available resources as cities are faced with challenges on energy, environment and climate. To improve on the efficiency of operations, the quality of life for its citizens and growing the local economy, cities are becoming more resource efficient, consumer-focused and technology-driven. A sustainable and smart city combines technological issues with societal dimensions that include economy, mobility, environment, culture and governance. Some of the top smart cities in the world are listed below:

1. Amsterdam, Netherlands

A smart-city platform, combining institutions and infrastructure, helps businesses and citizens develop and test green projects.  Amsterdam’s department for infrastructure has developed innovative products and services in the field of mobility, making available data on traffic and transportation to interested parties that include parking availability, taxi stands and cycle paths as well as live traffic updates. Developers and entrepreneurs are creating apps to improve the flow of people within the city such as Appening Amsterdam, a device to find out where to go on a night out and Drive Carefully, an app which alerts you if you are driving near a school. If you take a walk down “Climate Street” you will see nonpolluting electric trucks collecting trash and city bus stops and billboards powered with solar energy. Thousands of households and businesses have had their roofs retrofitted with energy efficient insulation cutting down energy costs. Electric power outlets allow river going vessels to recharge their batteries rather than using high polluting diesel generators. Several homes have been upgraded with automatically dimming light switches, automatic shutting off appliances, smart meters connected to cell phones and ultra-low energy LED lights.

2. Tokyo, Japan

Japan’s biggest companies such as Panasonic, Mitsubishi and Sharp are taking up charge to infuse smart technology to revolutionize the city. Panasonic have built an eco-village that focuses on renewable energy and ultra-efficient appliances. The zero carbon emission village encourages telecommuting to reduce on carbon dioxide emissions. Home automation systems have been installed to predict weather forecasts and determine the best time to do laundry. Next-generation fuel cells combined with solar power generators actually create electricity autonomously.

3. San Francisco, California
