Energy comparison: natural gas

Hi everyone,

Today we're talking about natural gas. Natural gas is a commonly used fossil fuel. So we thought we would go over the pros and cons of natural gas.

So first of all, we can quickly cover what natural gas actually is. In its natural form it's a mix of mostly methane and then some other chemical components like propane and butane. However, it's normally processed so that it's almost pure methane. Natural gas forms when organic materials (like dead plants and animals) are crushed into the ground. So it's like coal in that sense. The most popular theory is that the different conditions like temperature and pressure then control whether coal, oil, or gas is formed. Natural gas reserves are found globally. The largest gas fields are in Russia, under the North Sea, in the United States, Canada, Algeria and the Middle East. It's often found near to or even in oil fields. Natural gas is colourless, odorless, tasteless and obviously highly flammable. It's used for electricity production, heating and cooking, as fuel for some types of vehicles and in the manufacture of plastics, fertilizers and dyes.

Let's look at the benefits first. Natural gas is a lot cheaper than other energy sources. It has considerably less emissions than coal and oil and provides hundreds of thousands of jobs in different fields from electricians to physicists.

Unfortunately there are also downsides to this energy source. It is still a fossil fuel, meaning that it is not renewable. At some point, there will not be any left. Despite having lower emissions than coal and oil, it does still emit carbon dioxide and water vapour both of which are greenhouse gases. There are different ways to extract natural gas. One of them is fracking, which has profound environmental impacts. It not only uses a lot of water therefore depleting groundwater, it also produces toxic, radioactive wastewater and can also cause minor earthquakes, damaging infrastructure. The escaping gas from these processes is, of course, methane, which is a much more dangerous greenhouse gas than CO2.

In conclusion, while natural gas is a more environmentally friendly option compared to coal and oil, it is still a fossil fuel with the given limitations. Its cost-effectiveness and lower emissions make it a viable short-term solution, but considering the environmental effects and its non-renewable limitation it is still necessary to search for more sustainable alternatives.

April Top Tips: ten tips for environmentally friendly travel

Hi Everyone! We haven't been very present on the blog again recently but we are back today with ten top tips for environmentally friendly travel. Most forms of travel over long distances (unless you are willing to put in a lot of physical effort) use fossil fuels and are generally not good for our planet. So today we will be giving you a few tips which although won't mean that your travel is 100% planet friendly, will be a good start to doing as much as you can. Your Green World Blog Team💚 1. Use trains and boats rather than planes where possible Planes are awful for the environment. They are, however, extremely practical and so easy to use, cheap...It's hard to avoid them! They are so quick too so you don't have to spend as much time travelling. However, they are really bad for the environment. For example, you could fly once to Edinburgh from Heathrow for the same carbon dioxide levels as driving to Edinburgh 336 times! 2. Fly...

Animals 21-25 in our '50 incredible animals' series

Hi Everyone! Here are the next five animals in our current series! We hope you learn something from this. 21. Stick insect Stick insects are masters of disguise. They look like twigs or leaves. This strange appearance makes them hard to spot when stationary. Stick insects are herbivores, feeding on leaves, and can live for up to three years. Their habitat includes most tropical and subtropical regions, but there are a few species that live in temperate areas as well. There are roughly 3 000 different stick insect species! Not much more is known about them, because they are difficult to find. The two main threats to their populations are the pet trade and people killing them so as to frame their carcasses, like butterflies. Their conservation status ranges from critically endangered to least concern - so basically every category that is on the list! 22. Glass frog The glass frog is, well, see through. You can literally ...

29.11.2020 Animal Of The Week: Jaguar

Hello, Today (29th November) is world Jaguar day so this week our animal is the Jaguar. The Jaguar is an animal I know pretty much nothing about so I am going to learn a lot too! Jaguars (panthera onca) live for 12 - 15 years. Their heads and bodies are 150-180cm long and their tails are 70-90cm long! They weigh 45 - 110 kg. Habitat Jaguars live primarily in the Amazon Basin, though they can be found in smaller numbers in Central America. They once lived everywhere from central Argentina up to the southwestern United States but since the 1880s they have lost over half of their territory. They are mainly found in tropical rainforests but can live in savannas and grasslands. Diet They eat fish and turtles as they are actually quite competent swimmers as well as deer, iguanas, birds and monkeys; they will eat almost anything! Are they endangered? Jaguars are classed as near endangered and face several threats. South and Central Americ...

Eco Bricks -Taking Upcycling to another level

Eco Bricks Are they the key to the world's plastic pollution problem? Or at least a helpful factor if they became a permanent solution with no disadvantages? But what are they anyway? How are they useful? And how can individuals help every day? Here are some tips for everyone wanting to save plastic and help the earth. Eco bricks are plastic bottles, filled densely with hard and soft plastic that make a bottle so hard and sturdy that they could be used to build houses. Which in fact, they are. To make an Eco-Brick, you need a clean and dry plastic bottle, a long stick and lots of plastic. All plastic must be clean and dry, so it should be washed and dried or hung up to dry before usage. Now the bottle can be filled with layers of soft and hard plastic alternately that is pushed down with the stick to fill every corner of the bottle. That is done until the Eco-Brick is entirely stuffed with plastic and hard as a brick. The advan...

February 2021 Factfile - a bit of news from the last month and more!

Hi Everyone! Welcome to February's factfile! We are very sorry that we have not posted very much so far in 2021 but we are going to hopefully make up for it in the spring. News: Source- BBC Newsround The great yellow bumblebee has been spotted in Scotland! They used to be common in the UK but their population declined by about 80% in the last century. The find is a spark of hope as it is currently endangered. This is thought to be because of a decline in natural flower meadows and a boost in farming. The team of conservationists that found it were thrilled and when we heard about it we wanted to share it with you in case you hadn't heard! Source- Guardian In the 1840s a bird was caught in the East Indies. It had never been seen before and Charles Lucien Bonaparte (Napoleon's nephew) named it the black-browed babbler. The species wasn't seen again, so the only proof that it had ever existed was a stuffed specimen. ...

Green Pets: meet my house plants

Hi Everyone! Today I am writing a very exciting post as this is the first Green Pets post. Thank you so much to the person who suggested the name! Today I am showing you my house plants. I have two house plants but I hope to grow my collection! Vera, aloe vera (aloe barbadensis miller) I was actually very kindly gifted this for by birthday from a friend! It came in this beautiful pot with all these bees, that I just love! She suggested the name Vera and it's not very original but I still went with it because, why not? Our plant of the month for August ( click here to view ) was actually the Aloe Vera and it partly inspired me to start this series. I love having it in my room and I'm really trying to keep it alive, so far it's grown a lot since I got it! Bronausten, indoor fern (Nephrolepis exaltata) This plant is named after the Bronte sisters and Jane Austen, two of my favourite authors. It is an indoor fern and I l...

Green Pets: Introducing my new house plant!

Hi Everyone! As you can tell by the title of this post, I got a new houseplant! It was a Christmas present but I chose it in a really sweet plant shop near me. It is called a Mind Your Own Business, in more technical terms a Soleirolia. It's latin name is Soleirolia soleirolii. Introducing Mr Darcy! I named it Mr Darcy because I love Pride and Prejudice and I thought it appropriate! It needs to have constantly moist soil and has to be watered by being put in a bowl of water, rather than with a jug. This is because it will get a hole where the water has gone down as it is quite delicate and the leaves are very fine. It's important to look up how much water your house plant needs and get tips from experts to help your plant to thrive. I talked to the lady in the shop when we were buying it and she told me about how to look after it. It is joining my two other house pla...

Coral reefs

Hello! We would love to introduce you to the topic of coral reefs and especially coral reef bleaching, as it is a greatly ignored but certainly significant topic. Have fun! 5 coral reef facts 1. The Great Barrier Reef is the largest living structure on the planet and is 2300 km long! 2. Less than 0.1% of the world's ocean surface is covered in coral reefs. 3. At least 25% of all marine animals live there. 4. Coral reefs are often known as the rainforests of the ocean. 5. In 1 square kilometre of coral reef, up to 35 tons of fish can be 'produced'. The 5 biggest coral reefs in the world 1. Great Barrier Reef (near Australia) 2. Red Sea Coral Reef (near Egypt, Israel and Djibouti) 3. New Caledonia Reef (Pacific Ocean near New Caledonia) 4. The Mesoamerican Barrier Reef (near Mexico, Belize, Guatemala and Honduras) 5. Florida Reef (Atlantic Ocean/Gulf of Mexico near Florida) What is coral? Coral is actually made up of small anim...

November Top Tips | sustainable activities and hobbies

Hello everyone, So this week, we are going to be talking about sustainable free time activities. This area can quite big when it comes to environmental impact, so here are some things that you can do in your free time, that are more sustainable. 1. Reading So reading is one of our favourite things to do. However, books are made of paper and the paper industry isn't great. Some ways you can get around this is by reading online (for example, on a kindle), or through borrowing books from a library or using book boxes. If there aren't any in your area then at least try to support independent bookshops! 2. Running If you love being active then this one is for you. Running is probably one of the most sustainable forms of sport. All you need are some running shoes and somewhere to run. There is obviously more high-tech gear but that isn't really necessary if it's just a hobby. 3. Gardening If you've got a small area of land o...

The Responsible Traveller by Karen Edwards || a practical guide to reducing your environmental and social impact // BOOK REVIEW

HI Everyone! Our January monthly post was a zero-waste challenge, but as we explained in our 2023 wrap up , this year we will be alternating a monthly challenge with a book review, of course related to the environment. This week, I'm going to share a recommendation for a fantastic book, all about how you can travel more sustainably and responsibly. I absolutely love travelling, but I'm also very aware of the impact it has on the world, and I am very keen to learn more about how I can further reduce my impact. That's why I bought this book around a year ago, and I've really enjoyed reading it and learning from it. This is a practical, small-format guide, sharing both basic information about the climate crisis and the impact of various travel activities, and how you can do your bit. It shares specific journeys that are more environmentally friendly options, for example long distance train journeys such as The Alaskan Railroad with its stunning alpine forests and wide ar...
