Summary
Beijing
Area of Science:
- Environmental Economics
- Energy Systems Analysis
- Urban Metabolism
Background:
- Input-output analysis is a key method for tracking embodied energy across economic sectors.
- Beijing's rapid urbanization necessitates understanding its evolving energy consumption patterns.
Purpose of the Study:
- To analyze energy flows in Beijing using input-output tables from 1987 to 2007.
- To identify key drivers and sectors influencing embodied energy consumption during urbanization.
Main Methods:
- Utilized 9 economic input-output tables spanning 1987-2007.
- Analyzed energy flows for Beijing and its 30 economic sectors.
Main Results:
- Beijing's embodied energy consumption surged from 38.85 to 206.2 million tonnes of coal equivalent (Mtce).
- Indirect energy consumption rose from 48% to 76% of total consumption, indicating a shift to a service-based economy.
- Real estate and construction significantly drove indirect energy use, while transportation and services increasingly contributed to overall consumption.
Conclusions:
- Input-output modeling provides a robust framework for energy policy in rapidly urbanizing cities.
- Understanding sector-specific energy dynamics is crucial for sustainable urban development and policy interventions.

Population dynamics can be described mathematically by considering the population size P(t) as a function of time. The rate of change of the population is then represented by the derivative of P(t). A simple assumption is that the rate of growth is proportional to the size of the population itself. This leads to an exponential growth model, where the population increases rapidly without bound. While this is a useful first approximation, it does not reflect realistic long-term...

Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...

Drugs administered through various routes can lead to nonlinear elimination, resulting in complex pharmacokinetic behaviors crucial to understanding efficacious drug dosing.
When a drug is administered through a constant intravenous infusion and eliminated via nonlinear pharmacokinetics, it follows zero-order input. For example, oral drugs undergo first-order absorption upon administration and are eliminated through nonlinear pharmacokinetics.
In the case of subcutaneously administered drugs,...

When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves.
For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance,...

Applying the conservation of energy principle or the work-energy theorem to an incompressible, inviscid fluid in laminar, steady, irrotational flow leads to Bernoulli's equation. It states that the sum of the fluid pressure, potential, and kinetic energy per unit volume is constant along a streamline.
All the terms in the equation have the dimension of energy per unit volume. The kinetic energy per unit volume is called the kinetic energy density, and the potential energy per unit volume is...

In an electrical system with a resistor, voltage and current signals facilitate the measurement of power and energy across the resistor. For a continuous-time signal, the total energy over a time interval is defined as the integral of the square of the signal's magnitude over that interval. Mathematically, this is expressed as:
