Energy and Environment

1. Introduction
Energy is highly related to our daily life. For example, we need electricity for lighting and cooking. And electricity was earned by burning coal. There are mainly two different energy in the world. One is non-renewable energy and the other one is renewable energy.
(I) Non-renewable energy
Non-renewable resource is a resource that does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human time-frames. For example, coal, oil and nuclear power.
(II) Renewable energy
Renewable energy is generally defined as energy that

Status of Energy of Hong Kong
In order to facilitate or improve the quality of life, we try to put a lot of energy into electrical energy and other secondary energy sources, to promote a variety of tools or machinery for our work and services. This will make the energy hard to recover, and increase opportunity to release some of the human health and ecological environment of harmful gases and substances.

3. Impact on Environment
(I) Air Pollution
Air pollution is mainly caused by pollutants in the automotive, power plants, marine and industrial pollution emissions. Meteorological factors will make air pollution levels change. Sometimes in the still air pollutant dispersion and unfavorable weather conditions, air pollution may reach high levels. This is for people with heart or respiratory illnesses may cause adverse effects. The following is an introduction to some air pollutants:

(a) Sulfur dioxide (SO2)

Sulfur dioxide is a colorless gas with a strong pungent odor. The formation of sulfur dioxide during combustion of fossil fuels and processing of sulfur minerals. Hong Kong is a major source of sulfur dioxide from burning fossil fuel power plants and industrial furnaces vortex, is another source of emissions of motor vehicles and

Sulfur dioxide and nitrogen dioxide can cause respiratory problems, for example the asthma, cough and headaches, and eye, nose and throat irritation. Also, the indirect effects of acid rain is those poisonous metal dissolved in the water and those fruits, vegetables and animal tissue absorbed and human ate them. Although these toxic metals are not directly affected by these animals, but these animals eat but then affect human generation. For example, accumulate in animal organs and tissues of the brain damage and the mercury is associated neurological disorders. Similarly, the aluminum in the animal organs and kidney-related problems, has recently been suspected Alzheimer's disease. So the impact of acid rain on organisms in the food chain will be food and even
