Natural resources are inefficient, environmentally unfriendly and will be exhausted in near future. It will keep its advantages in such a way for the next 25 years. However, natural resources are still the number one resource in the world. It is cheap and relatively easy to access. The article will discuss whether we should continue to use natural resource or not.
Continue to use natural source
Despite there are renewable energy appears in recent years. Natural gas is still the cheapest resource human can utilize. Nuclear power is one of the most popular energy forms. Nuclear power has several advantages, it is efficient and renewable. But it requires huge amount of initial cost and it’s very dangerous to operate.
Some developed countries have already announced to give up using coal-fired power entirely. Those countries have better technologies and fund, which have ability to develop using new technology in the future. However, not all countries are wealthy enough, some government are still focusing on how to get rid of poverty. Natural resources are still one of the cheapest kinds of energy to use.
There are four popular fuels in our life: gasoline, natural gas, coal gas, coal. The basic chemical equation of these four fuels are:
|Basic chemical equation||Calorific value|
If a car wants to get 100MJ energy by these four different fuels:
|Type of fuel||Mass of fuel/ kg||Mass of / kg|
Comparing these four fuels, the natural gas is the most suitable. It almost has smallest mass of fuel and produces least . Natural gas is environmentally friendly because it produces the lowest greenhouse and noxious gas, such as , and , per kWh of energy produced. Coal and coal gas need to mine coal. The over exploitation of coal will cause the collapse of the earth’s surface. There are many cracks on the road in Henan province of China, which will lead to unsafe driving and increase traffic accidents. Relatively speaking, the exploitation technology of natural gas and gasoline is more environmentally friendly and safer. The natural gas can be compressed to reduce volume. The gasoline and coal are hard to compress. The coal gas is not hard to express but the essential component of coal gas is CO. CO leaks can cause carbon monoxide poisoning. So natural gas is the best choice.
Use renewable energy
Although natural gas is a clean energy resource and will not do harm to the environment, the process of drilling natural gas can release heavy metal elements or radioactive material which could threat ecosystem and the health of residents. According to the equality of duty ethics, people should be treated as equal. The health of residents should be concerned equally as other people. Not only the health, drilling of natural gas will cause the subsidence of ground which will influence the surface water flows and building foundations. It is not an equal respect to local people.
On the other hand, natural gas is a kind of fossil fuels which is not renewable. Overuse of natural gas will cause the growth of price due to the decrease in supply and increase in demand. Also, burning of natural gas will release carbon dioxide into the atmosphere, which will bring bad influence to the environment. It is unethical to burning natural gas because it will leave the environment issue to the next generation. Additionally, if natural gas become the main power source, energy resource will be distributed unjust among generations, thus using natural gas is unethical according to the Kantianism.
There are technologies which can reduce the impact of released CO2 while burning natural gas, such as carbon capture. Carbon capture is a process of capturing waste CO2 from the atmosphere. Carbon capture can reduce approximately 80–90 of CO2. It sounds perfect but the cost of the CO2 reduces technologies are high. For instance, Carbon capture will increase 21–91 of cost for a plant. It would be more effective to spend the money on development of renewables energies rather than natural gas like wind or solar power, which are clean energy. Therefore, it is a wiser choice to develop natural gas, renewables energies.
Because natural is not uniformly distributed around the world. Transportation and storage of natural gas are essential. Better pipeline and tank are required for natural gas compared with normal liquid fossil fuel. The specialised pipeline and tank for natural gas are more expensive, which means the cost of using natural gas is high. Long distance pipeline laying also harm the environment. Therefore, natural gas is not suitable to be a major energy, we should not develop it.
