The energy resources that we are using now are most from fossil fuels such as coal, oil and natural gases. Fossil fuels have many advantages. A major advantage of them is their capacity to generate huge amounts of electricity in just a single location. They provide energy for industrial activities, food production, electricity to run machines, etc. The cost of energy from fossil fuels is lower than other kinds of energy and they are very potential sources.

However, these natural resources are also very harmful.
(1)non-renewable energy is very harmful for the environment and human health. (2)Coal, oil burnings are major sources of carbon dioxide emissions (3)that causes greenhouse effects and the global warming. Environmentally, (4)the mining of coal results in the destruction of wide areas of land, causes pollution and other substances released when we exploit coal can cause lung or respiratory diseases. Besides these disadvantages, it can be seen clearly that (5)we are using the amount of fossil fuels faster than they can be replenished. (6)This leads to the shortage of energy for production and other activities and thus (7)affects the economies of many countries and the whole world. (8)Therefore, we should find alternative energy resources to meet our need and remain the energy resources for our future generations. (5) (2)
