Smart technology is ever increasingly present in the everyday lives of communities around the world. As urban areas become increasingly reliant on information technology, IoT gadgets, and wireless networks – evolving into smart cities-, sustainability becomes more and more significant. Cities like this must remain conscious of sustainable solutions to combat urban growth and CO2 emissions. Luckily with smart technology, many issues surrounding sustainability can be curbed despite energy usage and growing populations. For example, smart meters installed in houses help homeowners and tenants monitor their energy use.
Smart meters
Several UK companies already offer smart meters to help people choose wisely how and when they use energy, and with companies like OVO Energy, the findings can be accessed online and on a display screen in your home. According to UK Energy Minister, Claire Perry, smart energy could save the UK up to £40 billion from now to 2050. “Smart meters will be the cornerstone of a cleaner, flexible and efficient energy system, saving the country tens of billions of pounds”, she said.
Half a million households in the South West of England alone have already had a smart meter installed. And if every household in Britain had a smart meter, the national savings would be so enormous that we could supply energy to power the homes of hundreds of thousands of people.
Smart technology can also be used to benefit communities by tracking weather conditions with IoT sensors and apps, calculating water supply – researchers at the University of Waterloo developed an AI system to identify bacteria and contaminants in the water -,  and smart technology such as smart-bins can help monitor waste disposal to improve recycling.
The Internet of Things (IoT)
IoT takes up a critical role in the construction of a smart city, as IoT items that connect to the internet and
