What Are The Benefits Of Natural Gas

What is natural gas?

Natural gas is a fossil energy source that formed deep beneath the earth's surface. Natural gas contains many different compounds. The largest component of natural gas is methane, a compound with one carbon atom and four hydrogen atoms (CH4). We use natural gas as fuel, electricity and to make materials and chemicals.

What are the benefits of natural gas?

1. Produces cleaner fossil fuels

Natural gas is one of the safest and cleanest fuels available. It emits less pollution than other fossil fuel sources. When natural gas is burned, it produces mostly carbon dioxide and water vapor; the same substances emitted when humans exhale. Compared with some other fossil fuels, natural gas emits the least amount of carbon dioxide into the air when combusted; making natural gas the cleanest burning fossil fuel of all.

2. Produces 50% less carbon dioxide (CO2) than coal

Natural gas emits 50 to 60 percent less carbon dioxide (CO2) when combusted in a new, efficient natural gas power plant compared with emissions from a typical new coal plant. Considering only tailpipe emissions, natural gas also emits 15 to 20 percent less heat-trapping gases than gasoline when burned in today’s typical vehicle.

Light it up with wind!

“What we need to do is really improve energy efficiency standards, develop in full scale renewable and alternative energy and use the one resource we have in abundance, our creativity,”

Lois Capps.

In this era of globalization, to cater to humanity’s ever-increasing demand on natural resources and our high-consumption modern lifestyle, energy resources are quickly becoming scarce. As if the disaster of depleting energy resource is not enough, to make matters worse, the use of fossil fuel to generate energy for our everyday activities is contributing air-polluting particles to the environment, and adds to the accumulation of greenhouse gases that is directly linked to global warming (feeling the heat, anyone?).

Indeed, we should be concerned, and as such, it is only logic that everyone practices energy efficient routines. Simple habits as you go about your daily life, such as switching off and unplugging electrical appliances when not in use, using energy-saving electrical appliances, and utilizing natural lighting and ventilation, not only helps to reduce your energy usage, but also saves you money. However, though seemingly simple, many of us do not even bother to do our part. Even the thought of where our nation gets its electrical supply seems to be unclear to a lot of people. Try asking a group of secondary school students what they think is the main source of Malaysia’s electric generation, and the majority will answer hydropower, instead of natural gas and coal.

Realizing the importance to enhance the public, especially the youths’ understanding towards energy efficiency, Malaysian Gas Association (MGA) collaborated with Petrosains, and thus, the ‘Energy Efficiency Program’ was initiated. The program kicked-off in August 2014, and will end this August. With the purpose of raising awareness among students on the energy resources in Malaysia, as well as promoting the importance of using energy efficiently, representatives from Petrosains visited a total of 43 secondary schools, involving more than 2000 students. An interesting part of this visit-to-school program is that the students are given materials to build their own wind turbine, as an effort to expose them to alternative and green energy resources.

By using materials that are easily sourced out, the students were excited to find out that they are capable of building a functioning wind turbine that could light up a small LED light. In fact, you can do it at home too, what’s important is that your wind turbine design consists of a main frame structure that will hold everything together, the stator structure which includes the copper coils connected to an LED light, as well as magnets attached to the turbine structure that is free to spin, and is close to the copper coils to generate electricity. Upon completion, the wind turbine will be tested to see if the LED light could light up.

Let’s watch some snippets of the program:

It is hoped that by experiencing the hardship to generate even just a small amount of electricity, the students would appreciate the underlying message of the program. To strive for an energy efficient lifestyle is to help towards a sustainable environment, society and economy. To put it in the perspective of an ancient Indian proverb:

"Treat the earth well: it was not given to you by your parents, it was loaned to you by your children. We do not inherit the Earth from our Ancestors, we borrow it from our Children."
