Physics-energy production in Hong Kong and potential new ways of generating power.

Extracts from this document...


Major sources of energy in Hong Kong In Hong Kong, electricity supplied to the household and the industry comes from six production plants. The Castle Peak Power Station, located in Tap Shek Kok in Tuen Mun, has the greatest generating capacity in Hong Kong, up to 4110 MW. The Lamma Power Station is in Lamma, as its name suggests, comes second, having a generating capacity of 3305 MW. The Black Point Power Station in Northeast New Territories is in the third place, giving out 2500 MW of power. The Penny Bay's Power Station in Sham Shui Kok on Lantau Island produces the least generating capacity, at 300 MW only. The remaining two plants are not located in Hong Kong, but in mainland China. As the four plants aforementioned are not enough to satisfy the ever-increasing energy demand of Hong Kong, one of the two companies which provide us with electricity, the CLP Holdings (the other being Hong Kong Electric Co. Ltd), obtains energy from those two external power plants in China, the first being the Guangzhou Pumped Storage Power Station in Conghua, accounting for 1200 MW of our power, while the last one, the famous Guangdong Nuclear Power Station located in Daya Bay in Shenzhen, produces a mere 984 MW. ...read more.


Currently, oil burning is responsible for about 30% of all carbon dioxide emissions to air. Natural gas does not release as much carbon dioxide because of its methane structure. The largest emissions are cause by coal combustion. 2. Acid rain formation Burning of coal with high sulphur content will produce sulphur dioxide. Sulphur dioxide will harm human's respiratory system. When the gas dissolves in rainwater, acid rain will form. Acid rain affects marine lives and affects plants growth. It also attacks buildings and statues made from calcium carbonate. 3. Smog Burning coal without first purifying it contributes to the production of smog (smoke and fog). It affects health my irritating our respiratory system and eyes, and cause headaches 4. Water pollution The use of fossil fuels will cause pollution of water. Oil spills causes great harm to the environment. Most birds affected by an oil spill die unless there is human intervention. Marine mammals exposed to oil spills are affected in similar ways as seabirds. In addition, because oil floats on top of water, less light penetrates into the water, limiting the photosynthetic rate of marine plants and algae. Population of aquatic animals hence decreases. ...read more.


A large number of windmill is need to supply sufficient energy. It is only suitable for places of high altitude. Biomass The cost of producing energy from biomass is higher due to the special design of the boilers to facilitate combustion of biomass. Types of renewable energy suitable for remote places Wind energy Wind energy is a cheap and easy way to install wind turbines in remote area. It is suitable for small-scale electricity production. Little facilities are enough for providing electricity to isolated and remote locations. It also reduces the dependence of the locations on fossil fuels. Solar energy The energy and heat from the sun is free. Once solar panels or solar thermal collectors are set up, there are no electrical expenses necessary to power them. Solar cells require very little maintenance, greatly because there are no moving parts that must be maintained. Therefore, solar cells can last for a very long period of time. Solar power is incredibly versatile. A variety of inventions may be powered by it, including cars, water heaters, fountains, buildings, and satellites. In remote locations, solar power may be a more realistic energy option than running large lengths of electrical wires to connect to a grid. ...read more.
