About this Research Topic
Rapid urbanization is leading to smarter cities that improve the life of human beings. It is projected that about 60% of the world’s population is expected to live in cities by 2050 and investment in smart city technology is expected to grow to $135 billion by 2021. Nowadays, major metropolitan areas consume around 65% of available primary energy and contribute around 70% of greenhouse gas emissions for heating and cooling, illumination and transport. In addition to this, over 720 billion tons of waste is produced every year in worldwide cities. Hence, innovative solutions for energy-environment are needed in order to develop sustainable cities. These include smart and carbon-free transport, the use of renewable energy, effective greenhouse gas emissions management to reduce carbon footprint and pollutants to improve air and soil quality as well as waste management through and recycling by transforming conventional linear economy to circular economy.
The scope of this Research Topic recognizes the complexity of issues and challenges relating to environment and energy research with an interdisciplinary approach. It focuses on the “reduce, reuse and recycle” concept to achieve a sustainable future – including recent progress and research studies on energy demand and supply, economic, policy, communication, and social impacts of transportation and production systems, as well as contemporary technologies for environmental protection.
Submitted manuscripts may present theoretical, numerical or experimental findings within the context of energy research with an emphasis on energy saving and environmental protection incorporating the reduce, reuse and recycle concept. Interesting topics considered may include, but are not limited to, the following:
1. Emerging technologies that incorporate the reduce, reuse and recycle concept to promote sustainable energy and environment.
2. Innovative technology to promote for water-energy-health balance through the reduce, reuse and recycle concept.
3. Environmental regulations and energy policy to promote waste reduction and recycle resources.
4. Environmental and social impacts on renewable energy supply, green transport, and green production.
5. Emerging technologies that incorporate the reduce, reuse and recycle concept to achieve a circular economy.
