=====  Smart Grids =====
 

A smart grid is an energy distribution network integrating IoT technologies to monitor, manage, and optimise real-time electricity flow. Key features include:

  - **Energy monitoring and management:** IoT-enabled sensors and devices monitor electricity usage patterns, helping utilities optimise energy distribution and reduce wastage.
  - **Demand-side management:** Smart meters and IoT devices enable dynamic pricing and real-time feedback, encouraging consumers to use energy efficiently during off-peak hours.
  - **Integration of renewable energy:** IoT systems facilitate the seamless integration of renewable sources like solar and wind into the grid by managing variability and storage.
  - **Fault detection and repair:** IoT-based predictive maintenance systems detect and address network faults before they cause outages, saving energy and improving reliability.


=====  Smart Agriculture =====
 

IoT applications in agriculture, often called precision agriculture, improve resource utilisation and environmental sustainability. Examples include:

  - **Soil and crop monitoring:** IoT sensors measure soil moisture, nutrient levels, and crop health, enabling precise irrigation and fertilisation.
  - **Smart irrigation systems:** Automated irrigation systems use IoT data to water crops only when needed, reducing water and energy consumption.
  - **Livestock monitoring:** IoT-enabled collars and tags track the health and location of livestock, minimising resource use and ensuring timely intervention when needed.
  - **Climate monitoring:** Weather stations equipped with IoT devices help farmers predict environmental conditions and optimise planting and harvesting schedules.


=====  Smart Manufacturing =====
 

Also known as Industry 4.0, smart manufacturing integrates IoT technologies to enhance efficiency and sustainability in production processes:

  - **Energy-efficient production:** IoT sensors monitor machinery and processes, identifying areas where energy savings can be achieved.
  - **Predictive maintenance:** By analysing sensor data, IoT systems predict equipment failures and schedule maintenance to avoid energy-wasting breakdowns.
  - **Resource optimisation:** IoT-enabled systems track raw materials and energy use, reducing waste and ensuring sustainable resource management.
  - **Flexible manufacturing:** IoT facilitates dynamic adjustment of production lines based on real-time demand, minimising overproduction and associated energy costs.


===== Smart Home =====

Smart homes utilise IoT technologies to improve energy efficiency, comfort, and security:

  * **Energy-efficient appliances:** IoT-enabled devices, such as smart thermostats, refrigerators, and lighting systems, optimise energy usage based on occupancy and usage patterns.
  * **Home automation:** Systems like Alexa, Google Home, or Zigbee-based networks manage energy usage by turning off lights, appliances, and HVAC systems when not in use.
  * **Solar energy integration:** Smart inverters and IoT monitoring systems enable homeowners to optimise the use of solar panels and battery storage.
  * **Energy monitoring:** Real-time data from IoT sensors helps homeowners track and reduce energy consumption, lowering utility bills and carbon footprints.

===== Intelligent Transport Systems =====

IoT applications in transport focus on creating efficient, sustainable, and intelligent mobility systems:

  - **Traffic management:** IoT-enabled sensors and cameras monitor traffic in real-time, optimising traffic light systems and reducing congestion.
  - **Smart public transport:** IoT systems provide real-time information on bus and train schedules, encouraging the use of public transport and reducing emissions.
  - **Fleet management:** IoT technologies in logistics optimise routes, monitor vehicle health, and ensure efficient fuel use.
  - **Electric vehicle (EV) ecosystems:** IoT-enabled charging stations provide real-time availability updates and optimise energy use by balancing grid demand.

===== Smart Cities =====

Smart cities integrate IoT solutions across various urban systems to improve sustainability and quality of life:

  * **Smart waste management:** IoT sensors in bins monitor fill levels and optimise waste collection routes, reducing fuel usage and emissions.
  * **Energy-efficient buildings:** IoT-enabled systems in commercial and residential buildings optimise energy use for lighting, heating, and cooling.
  * **Air quality monitoring:** IoT devices track pollutants, providing actionable data to improve urban air quality.
  * **Public safety and infrastructure monitoring:** IoT sensors monitor infrastructure health (e.g., bridges, roads) and enhance public safety through real-time alerts.
  * **Water management:** IoT technologies optimise water distribution, detect leaks, and monitor quality, ensuring sustainable usage.

===== Internet of Food (IoF)=====

IoF integrates many of the applications mentioned above. It enables to track food manufacturing and ensure food quality and proper nutrition:

  * **Delivery chain tracking:** ensures that food origin, processing and delivery channels are according to the records. This technology frequently uses RFIDs, QR codes and blockchain.
  * **Nutrition information** enables consumers to select the best diet according to their needs carefully.
  * **Expire date active tracking:** optimises food consumption on a global and local scale, lowering the amount of wasted food.
  * **Quality monitoring:** relates to delivery chain tracking and provides a mechanism to track counterfeited food and simplify cases such as mass intoxication.

Green IoT applications represent a vital step toward achieving a sustainable future. By enabling more innovative resource use and reducing energy consumption across diverse domains, they address environmental concerns while improving functionality and efficiency.
