A natural gas flame

A gas that is made up mostly of methane and found near other fossil fuels, like coal. Methanogenic processes occurring in landfills and marshes also produce natural gas. Like petroleum, natural gas must first be processed before we can use it as a fuel. It is important to remove most of the other components of natural gas until it is almost purely methane. When combusted, natural gas produces only about half the greenhouse gas emissions as coal does, making it a popular fossil fuel in our increasingly carbon-conscious society.

XV. Read the passage and answer the question.
A carbon footprint is the amount of carbon dioxide (CO2) released into the air by your own energy needs. You need transportation, electricity, food, clothing, and other goods. CO2 is produced by the burning of fossil fuels which is used to provide energy for your homes, by the cars you travel in and by the manufacture and transport of goods you buy.
Carbon dioxide is also called greenhouse gas, which causes global warming. That is the reason why the carbon footprint is a very poweful tool to understand the impact of personal behaviours on global warming. If you want to contribute to stop global warming, the reduction of your personal carbon footprint is essential. Fist, you can reduce your carbon footprint by driving less. When possible, walk or ride a bike to avoid carbon emissions completely or use public transport in order to decrease CO emissions. Second, support using clean energy sources such as wind, solar, geothermal energy and biogas. Finally, reusing or recycling items you no longer use is also a good way to reduce your carbon footprint.
1. What is a carbon footprint?
A carbon footprint is the amount of carbon dioxide (CO2) released into the air by your own energy needs.
2. How is CO2 produced?
CO2 is produced by the burning of fossil fuels which is used to provide energy for your homes, by the cars you travel in and by the manufacture and transport of goods you buy.
3. What can carbon footprint cause?
It can cause global warming.
4. What should you do to stop global warming?
Driving less, supporting using clean energy sources such as wind, solar, geothermal energy and biogas.

Giải thích: When you choose green energy, Bullfrog's generators put clean, renewable electricity and/or green natural gas (produced from organic waste, not fracking) into the grid or pipeline to match the amount of power or natural gas your home uses.
Dịch: Khi bạn chọn năng lượng xanh, máy phát điện của Bullfrog đặt điện sạch, tái tạo và / hoặc khí tự nhiên xanh (được sản xuất từ chất thải hữu cơ, không rán) vào lưới điện hoặc đường ống để phù hợp với lượng điện hoặc khí tự nhiên mà nhà bạn sử dụng.
1 Air travel is usually the largest component of the carbon footprint of frequent flyers. A single return flight from London to New York – including the complicated effects on the high atmosphere – contributes to almost a quarter of the average person’s annual emissions. The easiest way to make a big difference is to go by train or not take as many flights.
2 The second most important lifestyle change is to eat less meat, with parular emphasis on meals containing beef and lamb. Cows and sheep emit large quantities of methane, a powerful global warming gas. A vegan diet might make as much as a 20% difference to your overall carbon impact but simply cutting out beef will deliver a significant benefit on its own.
3 Home heating is next. Poorly insulated housing requires large quantities of energy to heat. If you have properly insulated the loft and filled the cavity wall, the most important action you can take is to draught-proof the house, something you can do yourself. Those with solid brick or stone walls will also benefit from adding insulation, but the financial benefits are unly to cover the cost of doing the work, over time.
