Overview

Why do we need to Safety in using fuel and handle gas leaks? Why do we feel town gas smell? How is electricity located at electric station far away from town area? How to solve problems caused by the use of fossil fuels? How to reduce the use of fossil fuels?To solve the problems, the best way is to reduce our used of fossil fuel. This helps prevent fossil fuels form being used up too quickly. Also, it helps us to reduce environmental problems because fewer pollutants are given out when less fossil fuels are used. Can human help to reduce the use of fossil fuels? Fossil fuels are mainly in power station. Although we use some fossil fuels for our gas cooker and car, it won't make much difference if I use less. Fossil fuel is not used renew primary energy. Most of energy we use come from fossil fuels, for example, the electricity we use is generated in power stations by burning fossil fuels. The buses we ride use diesel oil. Therefore, we can help reduce the use of fossil fuels by saving energy in our daily lives. The actions that we can take such as: setting the air-conditioner to a higher temperature, walking instead of using lift, taking a short shower instead of a bath. This reduces the use of the hot water and thus the energy needed to heat the water. Thus, many people can help a lot to reduce our use of fossil fuels to avoid fossil fuel shortage risk occurrence. For Hong Kong people energy consumption case, how much energy is used when a person travels from Hong Kong to Beijing by airplane? (The distance between Hong Kong and Beijing is about 2000 km). How much energy is used when Hong Kong people take a bus form Tai PO city to Central city? How much energy is used if Hong Kong people drive a car instead? ( The driving distance between Tai Po city and Central city is 10Km).Science explorer, we can visit the England website. Find ways to reduce energy usage from UK people energy using methods. Energy is very important to us. We need energy to walk and carry on any actions. We need energy to grow. We also need energy from food to survive. Without energy, we will die. All machines we use need energy. Without energy the electrical appliances in our homes won't work, the machines in factories will stop.There are different forms of energy, e.g. light, heat, sound, wind, water, electrical kinetic, chemical and potential energy. Some form energy is primary energy.
