Summary
China
Area of Science:
- Energy Economics
- Environmental Science
- Operations Research
Background:
- China's economic growth drives high energy consumption and environmental issues.
- Reducing energy intensity is crucial for sustainable development.
- Existing Data Envelopment Analysis (DEA) models have limitations in assessing energy efficiency.
Purpose of the Study:
- To propose a modified undesirable Epsilon-based Measure (EBM) DEA model.
- To analyze the energy efficiency of new and traditional energy sources in China.
- To address limitations of traditional radial and non-radial DEA models.
Main Methods:
- Development of a modified undesirable Epsilon-based Measure (EBM) DEA model.
- Integration of Epsilon-based Measure (EBM) DEA with undesirable output considerations.
- Empirical analysis of energy efficiency in Chinese municipalities/provinces.
Main Results:
- New energy investment saw rapid growth from 2013-2016 in most regions.
- Significant efficiency improvements are needed in 26 out of 30 municipalities/provinces.
- Traditional energy efficiency scores generally exceed those of new energy sources.
- Nitrogen Dioxide (NO2) efficiencies slightly outperform Carbon Dioxide (CO2) and Sulfur Dioxide (SO2) efficiencies.
Conclusions:
- The modified undesirable EBM DEA model effectively analyzes energy efficiency with undesirable outputs.
- Substantial improvements in new energy efficiency are required across most of China.
- Policy interventions may be needed to enhance new energy efficiency and balance development.

02:39Emission Spectra
75.9K
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.

04:10What is Energy?
58.6K
The universe is composed of matter in different forms, and all forms of matter contain energy. The different forms of energy on Earth originate from the Sun — the ultimate energy source. Plants capture light energy from the Sun, and, via the process of photosynthesis, convert it into chemical energy. This stored energy from plants can be harnessed in many ways. For example, eating plant products as food provides energy for our body to function, and burning wood or coal (fossilized...

01:21Free Energy
51.8K
Free energy—abbreviated as G for the scientist Gibbs who discovered it—is a measurement of useful energy that can be extracted from a reaction to do work. It is the energy in a chemical reaction that is available after entropy is accounted for. Reactions that take in energy are considered endergonic and reactions that release energy are exergonic. Plants carry out endergonic reactions by taking in sunlight and carbon dioxide to produce glucose and oxygen. Animals, in turn, break...

03:25Free Energy Changes for Nonstandard States
13.4K
The free energy change for a process taking place with reactants and products present under nonstandard conditions (pressures other than 1 bar; concentrations other than 1 M) is related to the standard free energy change according to this equation:

00:52Potential Energy
42.4K
The energy stored by a structure and location of matter in space is called potential energy. For instance, raising a kettlebell changes its spatial location and increases its potential energy. Similarly, a stretched rubber band contains potential energy which, under certain conditions, can be converted into other forms of energy, such as kinetic energy.
Chemical bonds that form attractive forces between atoms also contain potential energy, called chemical energy. When a chemical reaction...
