for the urban transportation because of their sustainability, High torque, low volume, zero emission and energy saving. Electric scooter can go certain limit of distance based on the battery capacity it consists. This paper presents the model construction of an energy regenerative electric scooter via MATLAB/SIMULINK so that one can evaluate the performance of the energy recycling technique for...

The development of the urban economy and effect linkage radiation are inseparable from transportation system’s efficient operation. In context new era, environmental pollution caused by economic has gradually become an invisible killer that endangers human health atmospheric environment. It is a pillar industry development, key part infrastructure construction, necessary guarantee for residents...

Abstract Industrial carbon emissions are the main part of China’s emissions, so industrial emission reduction is an important tool to achieve ‘double carbon’ target. This paper constructs a Tapio model decompose total decoupling indicators into energy-saving and emission-reduction indicators, with view revealing more deeply reasons mechanisms for changes in between economic growth CO2 sector ea...

China, as the world’s largest cement producer, accounts for more than 60% of global cement production. With the continuous development of the Chinese economy, resource and environmental constraints are becoming increasingly serious, and energy saving and emission reduction has become one of the choices with which all industries are faced in the process of development. The cement industry is one...

Energy crisis, global warming and other environmental issues are what motivate researchers to find new strategies to reduce energy consumption in buildings. Recently, using phase change materials (PCM) in the building’s envelopes has drawn significant attention as an energy-saving method, which helps in increasing the building’s thermal capacity. In the present research, the effects of the main...

Low-Carbon Technologies (LCTs) play an important role in achieving China’s Intended Nationally Determined Contributions (INDC) targets. According to the result of our scenario analysis, if advanced energy-saving technology, renewable energy, and other measures are promoted and extensively applied, China’s carbon emission will achieve its peaking at around 2027. With proper energy policies, Chin...

In response to the call for carbon neutrality and control of CO2 emission, this paper proposes a high temperature cascade heat pump system with double medium low sources. Compared those single source, new has obvious advantages in energy saving emission. An experiment is designed where source keeps unchanged, revealing that, compared heating capacity reduces by 2.9%, increases 31.1%, total powe...

This paper introduces the purpose and significance of safety evaluation hoisting machinery, summarizes various method, discusses advantages disadvantages methods, analyzes current situation machinery in China, puts forward corresponding suggestions on energy saving emission reduction through evaluation.
