Developing smart and cost-effective generators is crucial to meet the energy demands of the modern world. 

FREMONT, CA: We live in a world where energy is indispensable. The growth and development of the economy depend on it. The most important issues are climate change, sustainable development, health, and global food security. Governments worldwide have been looking for smart ways to generate, control, supply, and save energy due to the ever-increasing cost and demand. Smart homes save money and reduce carbon footprints by using energy efficiently. Renewable energy sources such as photovoltaics, hydroelectricity, wind, tidal, and geothermal energy have advanced significantly. 

Smart cities

Globally, cities are a form of settlement growing at the fastest rate, requiring energy to maintain their existence. Global urbanization and socio-economic challenges have prompted the concept of a smart city. The idea of smart cities is essential to creating an efficient and livable environment using digital technology. Intelligent cities have electronic and digital technologies that enable their devices to communicate. The IoT and big data are closely related technologies that enable smart cities. A smart home, smart city, or smart building can reduce greenhouse gas emissions by efficiently using energy. 

Smart home

The smart home is one of the emerging infrastructures. The smart home is a building block for smart cities and intelligent communities. In a smart home, devices are controlled remotely using smart features and technology. Home assistants use sensors to collect data, use AI to make suggestions, and automatically adjust the temperature. By monitoring energy consumption, smart energy can control household appliances in an energy-efficient manner.

Smart building

A building consumes a significant amount of energy and is one of the world's largest producers of carbon dioxide (CO2). They must use energy for cooling, heating, hot water, and lighting to function properly. Smart buildings can be built, and new standards and regulations can ensure less energy consumption. The major technologies used to achieve a smart building include smart meters, smart lighting, smart grids, ICT, and the energy Internet. Smart buildings can communicate with their inside devices and appliances via ICT.

Transportation

Quality of life is affected by transportation. The country consumes much global energy and relies heavily on oil-based fuels. The city can play a key role in encouraging alternative modes of transportation by providing leadership in this area. Mobility in a city is best ensured by public transport, and smart grids and smart cities are interconnected. The components of this system include the infrastructure, the vehicles, and the users.
