Only when there is extreme environmental pressure or substantial reduction in loads that conversion from coal to 100% natural gas is possible.
Not until the 20th century until natural gas was used for production of energy, it was dismissed as a useless byproduct of crude oil production until then. But now natural gas accounts for 23 percent of the world’s energy consumption and still growing. The International Energy Agency predicts that the demand for natural gas will grow by approximately 44 percent through 2035.
Natural gas is the cleanest-burning conventional fuel not to mention it has been one of the most economical energy sources. It is an environmentally friendly and efficient source of energy. It produces lower levels of greenhouse gas emissions than heavier hydrocarbon fuels such as coal and oil. Natural gas fuels electric power generators, heats buildings and is used as a raw material in many consumer products, such as those made of traditional plastics. However, natural gas has never been a cheaper fuel than coal.
Coal is one of the longest-used and is considered as the most abundant fossil fuels on Earth. Coal mining has been going on since then 17th century. Coal burning boilers have also been around for a long time, and while they may not always be popular, these machines have some definite advantages in terms of costs and simplicity.
Because it is the most abundant it is the cheapest form of fossil fuel to burn. But coal boilers on the other hand have harmful effects on the environment and human health. Its emissions contain sulfur combines with air to create the poison gas sulfur oxide. When this gas releases into the atmosphere, it causes polluting rain. Extracting coal from mines further damages soil and water resources, adding to the disadvantages of using coal burning boilers.
While coal prices are expected to remain stable natural gas prices are expected to increase as higher cost natural gas reserves need to be developed to meet growing demand and offset losses from depleting gas wells. On the other hand, natural gas based technologies have a capital cost advantage.
Whatever the costs may be, don’t you think it is better to use natural gas rather than the coal boilers? Even though natural gas is more costly than coal boilers it is less harmful to the environment and to human health. It is always better to take into considerations the things that are more important than money. It is not wise to be thrifty over something that in a long run would back fire on you and worst your kids. Long term effects of coal boilers are scarier than the costs in terms of money that it will bring us today. Environmental effects and health issues will sure be more costly in the future.
