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.

Animals 31-35 in our '50 incredible animals' series

Hi Everyone! Welcome back to our blog, today we are sharing another 5 incredible animals. This is part of a series to celebrate our 50th blog post, all about unusual animals! Enjoy! 31. Pangolins These creatures are often mistaken for reptiles but they are in fact mammals. They are covered in scales and use them to defend themselves because similar to a hedgehog, they curl up into a ball. They eat ants, termites and larvae. They eat using their tongue, which is very long- sometimes even longer than their body! Sadly, Pangolins are in high demand as their meat is considered a delicacy their scales are used in traditional folk remedies, which means that there is an illegal trade. Luckily, there have been many initiatives put in place to help these animals by WWF and similar organisations. 32. Macropinna Microstoma This is a species of fish that live at about 600m below sea level. They hang nearly motionless in the water and have a very unusual...

Photo Essay || Iceland Series (part 1)

Hi Everyone! I recently went on a school trip to Iceland! It was such an incredible experience (and I'm going to sound cheesy now) but it was also incredible to do it with some of my closest friends! I saw so many incredible things and learnt so much, so I couldn't resist sharing a little Iceland mini series of posts, all about Iceland, both my experiences there and what I saw, but also the way it uses geothermal energy, and the animals, natural landforms and plants that are there. Today I'm sharing some photos of my trip. These are all photos I have taken, and are also the highlights so please bear that in mind as you browse these! I hope it is interesting and inspires you to book a trip to Iceland! The blue lagoon <33 landscapes.... Lost little farmhouses a...

Discussion || Should Everyone Switch To Electric Cars?

Hi Everyone! Thank you so much for joining me today, as I hop on the blog to discuss whether everyone switching to electric cars would really help the environment. In other words, should everyone switch to electric cars? This is the first part of a two-part series, discussing electric cars, so stay tuned for part two!! I would like to start this post by stating that I am by no means an expert. This is knowledge I have from my own experience, and from research I have done. If anything is incorrect please take it as it is and accept that this is a discussion and I am taking on board all opinions from reliable sources on this complex topic. Electric cars are a huge topic when it comes to sustainability and "saving our planet". There is no debating the fact that electric cars are better for the environment than diesel or petrol once they are on the road. But the production of them is often very polluting, with one study show...

Deforestation and why it’s a problem

Hi everyone, Welcome back to another post. Today we’ll be talking about deforestation and its impacts on our earth. Deforestation, the widespread clearance of natural forests, has been happening for thousands of years. One example is Western Europe, where, two millennia ago, 80% of the land was cloaked in dense forest cover. However, over time, a significant portion of this green expanse was sacrificed to create room for crops, livestock grazing, and as a source of fuel and building materials. Presently, a mere 34% of Western Europe retains its woodland. Today, the tropics deal with the brunt of deforestation. Activities such as mining, agriculture, road construction, and the establishment of vast cattle ranches drive the mass clearance of tropical rainforests. This results in the release of huge amounts of carbon dioxide into the atmosphere, exacerbating the global climate crisis. The consequences come in two waves: first, the reduced number of...

Carbon credits

Hi everyone, Welcome back to Green World! Today we're talking about an industry that has expanded massively in the past few years. Carbon credits are one of the measures that companies are taking to reduce CO2 emissions . But how does it actually work? The companies that sell carbon credits fund projects to protect an area of forest or rainforest from deforestation . They then calculate how much carbon dioxide emissions they have saves by protecting this area. This means they can now sell 'negative carbon emissions' to companies. In this way, the companies are funding the protection of said area and are causing negative emissions while doing so meaning that the company can still emit greenhouse gases but can claim to be net zero. One carbon credit is basically the permission to emit one ton of CO2. This is good for the company as well as they are able to advertise as sustainable at a relatively low cost to actually reducing the...

October 2021 Factfile | news, animals and more!

Hello, October is over and November is here - let's hope it's a cosy month full of stunning Autumn colours and beautiful rainy days! News Good news Judge postpones wolf hunt in Wisconsin Every year in Wisconsin there is a wolf hunt in autumn. But this year, something amazing happened: A judge halted the season. For years there has been a dispute, on one side environmentalists, and on the other hunters and farmers. The farmers claim that wolves destroy their crops and that killing them is the only solution. Environmentalists argue that wolf populations are too weak and that the animals shouldn't be killed. Let's hope that this is the first step toward stopping the wolf hunt altogether. Bad news Pacific islands are disappearing For many of us, the threat of climate change feels distant. But for the people of the Pacific islands, the terror is all too real. These are their homes, and they are rapidly becoming submerged b...

Jane Goodall

Born: 1934 When Jane was a little girl, she loved climbing trees and reading books. She dreamed that she could go to Africa and see the wild animals there. So Jane flew to Tanzania determined to study chimpanzees in their natural habitat. When she first arrived, none of the chimpanzees would let her get near them. They would always run away at first sight. Jane kept coming back until they let her come closer. However, Jane wanted to become friends with the chimpanzees. So she started the "banana club" which meant that she would share bananas with them every time she visited the chimpanzees. She discovered that chimpanzees have rituals, that they use tools, that their language comprises at least twenty sounds and that they are not vegetarians. Once she rescued an injured chimpanzee and nursed it back to health. When she released it back into the wild, the chimpanzee turned around and hugged her as if to say, "thank you and goodby...

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...

18.10.20 Animal Of The Week: Sloth

Hello, Sorry this didn't come out on Sunday as planned but this week's animal of the week is the sloth because the twentieth of October is Sloth Day. Habitat The sloth resides in Central and South America. It lives in the rainforests there and occasionally drops into the water for a bathe as, believe it or not, they are actually excellent swimmers! Diet Sloths eat leaves, twigs and buds which they find in the rainforest. As they don't have incisors they smack their lips together to make leaves more digestible. Sloths can survive on relatively little food as it takes a while for them to digest it. Sleep and Speed When you think of a sloth, you probably think of this slow, sleepy creature. They actually sleep for about 15 hours a day! Sloths have an extremely low metabolic rate (what basic calories your body needs to survive), which means they move at a slow pace through the trees. On average, sloths travel 40 yards per day ...

July 2021 Factfile - some news from the past month, animals and plants!

Hi Everyone, July is over and August is here. This month we've divided the 'News' section into 'Good news' and 'Bad news'. This will hopefully make the post more structured and easier to navigate. News Good news: Pandas classified as vulnerable Giants pandas are now classified as vulnerable according to Chinese officials. They were originally classed as endangered , but now that numbers in the wild have gone over 1 800 they have been reclassified. This is due to hard conservation work in China and funds from volunteers all over the globe. However, they are still vulnerable so it is important that the good work continues. For all those who have supported giant pandas through websites or those who work actively with them: keep up the good work! First baby beaver born on Exmoor in 400 years A baby beaver has been born on Exmoor, England, for the first time in 400 years! This is due to ...
