“…The current switch from fossil fuels to renewables is driven primarily by climate change and the necessity to reduce emissions. In comparison to natural gas, coal emits higher levels of carbon dioxide (43,8%), nitrogen oxides (80%) and sulfur dioxide (100%) (Qyyum et al, 2019). For developing countries, those that are dependent on coal, natural gas consumption is considered vital.…”

The international community has become increasingly concerned with sustainable development and particularly with preventing climate change. The COVID-19 pandemic and global recession of 2020 will exacerbate the situation not just for 2020–2021, but for many years to come. Sadly, it is a game-changer. The necessity to solve problems of poverty (energy poverty) and inequality, as well as growth and climate change mitigation, now haunts intellectuals, forecasters, and politicians. These three problems constitute the global energy trilemma (GET). There is a wide range of forecasts, scenarios, and political plans emerging after the Paris Agreement in 2015. They demonstrate concerns about the slow progress on the matter; however, they still increase the goals for 2030–2050. The global capital formation is a key tool for changes while also representing the hard-budget investment constraints. This article examines practical features of recent trends in energy, poverty, and climate change mitigation, arguing that allocation and coordinated management of sufficient financial resources are vital for a simultaneous solution of GET. No group of countries can hope to solve each of the Sustainable Development Goals (SDG) separately. The global economy has reached the point where it has an urgent need for cooperation.

“…With the large amount of air pollution caused by the traditional energy consumption represented by coal, oil and firewood, human society has been paying more and more attention to natural gas as a relatively clean energy [1]. Except for the direct consumption as fuel, natural gas has shown attracting potential in electricity generation for both economic and environmental concerns [2].…”

The thermodynamic properties of fluid mixtures play a crucial role in designing physically meaningful models and robust algorithms for simulating multi-component multi-phase flow in subsurface, which is needed for many subsurface applications. In this context, the equation-of-state-based flash calculation used to predict the equilibrium properties of each phase for a given fluid mixture going through phase splitting is a crucial component, and often a bottleneck, of multi-phase flow simulations. In this paper, a capillarity-wise Thermodynamics-Informed Neural Network is developed for the first time to propose a fast, accurate and robust approach calculating phase equilibrium properties for unconventional reservoirs. The trained model performs well in both phase stability tests and phase splitting calculations in a large range of reservoir conditions, which enables further multi-component multi-phase flow simulations with a strong thermodynamic basis.

“…Energy is considered to be critical in societal and industrial activities, especially in intelligent manufacturing and robotics [1]. As the energy consumption is a recent global concern in sustainable manufacturing, it should take the responsibility through a low energy cost approach to clean energy [2], a low carbon footprint approach based on low carbon emissions [3], a low-product environmental footprint approach to sustainable assessment [4,5], optimized model-driven energy efficiency improvement methods [6,7], and sustainable design [8,9]. Current methods for low energy could be basically classified to increase energy efficiency and to reduce energy consumption in sustainable manufacturing.…”

As the energy efficiency is a worldwide topic for sustainability in sustainable manufacturing, the industry ought to undertake the responsibility in a low energy manner. For energy efficiency, this paper proposed a novel lightweight non-holonomic spherical underactuated robot (NSUR) with lower energy consumption and fewer actuators than traditional robotics. The kinematics of a robot refers to the motion analysis, such as coordinates, velocity, and acceleration. However, current researches always focus on the holonomic full-actuated robot. This paper is devoted to a kind of novel NSUR and its theoretical kinematics analysis model. After NSUR was introduced, the kinematic representation of NSUR was discussed. A pair inverse and forward kinematics analysis of NSUR was put forward in detail. The kinematic analysis of joint of underactuated robot, as the application of NSUR, is applied to explain and verify this methodology. The measurements and comparisons of energy efficiency between NSUR and traditional robotics are also derived in detail.
