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.

19.07.2020: Animal of the week: Honey Bees

Hi everyone, This week's animal is the honey bee. Enjoy! General Information An average honeybee hive is made up of one queen, hundreds of male drones and thousands of female workers. If the queen bee dies then a new queen is created. The workers select a young larva and feed it with a special food called ‘royal jelly’. The ‘royal jelly’ makes the larva grow into a fertile queen. Queens live for several years but the workers only live for five or six weeks. An average worker will make a twelfth of a tee spoon of honey during her entire life. Drones are turned out of the hive and left to die in Autumn. In the summer months, the queen bee is very busy, she can lay up to 2500 eggs in a single day. How they affect the world around them Honey bees are very important for flowers, fruit and vegetables. This comes from the fact that they are pollinators. They help the plants by transferring pollen between male and female parts, meaning the plants can g...

Heatwaves - what's so bad about them?

Hi everyone, Today we’re talking about heatwaves and what effects they have on us and the environment. Heatwaves are becoming ever more common, with 2023 breaking multiple world records. In China, 52.2°C were recorded at one point and the coastal waters near Florida, USA, were as warm as a hot tub. This is because of the combination of climate change and El Niño , both of which make the effects of the other worse. But we can’t push the blame onto El Niño. When analysed it became clear that without human made climate change the USA heat records would have been almost impossible. So what exactly are the effects of such high temperatures. A study in Europe found that the 2022 heatwave possibly caused over 70 000 heat related deaths. Although it is sometimes hard to tell whether or not someone died from the heat or from something else, after analysing the data the team found that their original estimate of 62 000 people (which is still a lot) was probably ...

The life of ... an alcon blue butterfly

Hi everyone, Today we are going to be looking into the life of an alcon blue butterfly (Phengaris alcon). After mating, the females lay their eggs on marsh gentian, a blue-coloured wildflower. The eggs can only be laid on these flowers, as this is what the newly hatched caterpillars will eat. Although in some alp regions, they can also be found on willow gentians, a close relative of the marsh gentian. Once the caterpillars have hatched from the eggs, their main predator and danger are the ants that swarm below. But high on their plant homes, the caterpillars are safe. However, this isn't where the alcon blue caterpillars are going to stay forever. Eventually, they drop down to the ground using silk strings. With no protection, they are soon dragged off by the ants. The most amazing part is, the alcon blue caterpillars give off the same scent and chemicals as the ant larvae. So the ants take the caterpillars back to their brood chamber, wher...

16.08.2020 Animal of the week: Elephant

Hello. On the 12th of August it was International Elephant Day, so we decided that this week's post should be about elephants. Elephants are the largest living land mammals. There are three types of elephant; the African bush elephant; the African forest elephant and the Asian elephant. African elephants have larger ears, whereas Asian elephants have smaller ears. Elephants use their trunks to breath, bring food and drink to their mouths and to grasp objects. Elephants' legs are like pillars. They carry the Elephant's massive weight. African bush elephants weigh 6000kg, Asian elephants weigh 4000kg and African forest elephants weigh 2700kg. Basically, they are very heavy.Elephants eat grasses, small plants, bushes, fruit, twigs, tree bark, and roots. Elephants can live up to 70 years old in the wild. They communicate by sight, touch and smell. Sadly, these wonderful mammals are in danger. African elephants are listed as vulne...

Animals 46-50 in our '50 incredible animals' series

Hi everyone! Welcome to the final part in our '50 Incredible Animal series' where you can find out about animals 46-50. We started this series almost a year ago to celebrate our 50th post and it feels crazy to think that we are now nearing our 100th. To read all of the previous posts from this series, click here . Hope you enjoy it! 46. Spiny bush viper Spiny bush vipers, Atheris hispida, are a species of venomous snake native to Central and East Africa in tropical forests and shrubland. They are mostly solitary creatures but can climb trees, which is where they find the majority of their prey. Spiny bush vipers are carnivorous and feed on mammals, frogs and lizards, as well as birds. Independent from birth, Spiny bush vipers can have up to 12 'snakelets' at a time and are 15cm in length. Currently, there are no known threats to Spiny bush vipers, and they are categorized as Not Evaluated on the IUCN Red List. 47. Leafy sea dragon ...

Maria Sibylla Merian

Hello, Today we wanted to tell you all about Maria Sibylla Merian. Maria was born in Germany on 2nd April, 1647. Like many young girls at that time, she loved to paint. Every day she would gather flowers from her garden and paint them. Sometimes, the flowers would have caterpillars on them and she would paint them changing, day by day, into butterflies. At that time, not much was known about insects, and people thought that butterflies magically sprouted from the mud. Maria knew from what she had seen while she was painting, that this was not true, but no-one believed her. As time went by, Maria became a great watercolour artist. She wrote about her discoveries, but scientists only took books written in Latin seriously, and Maria wrote hers in German. When Maria and her daughter were living in Amsterdam, Maria found display cases in museums filled with exotic insects collected from South America. Maria thought that if she could study the bu...

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...
