Geothermal and Hydropower Energy in Iceland || Iceland Series (part 2)

Hi Everyone!

If you saw part one to the new Iceland mini series, you may know that I recently went to Iceland, and I wanted to share a little about my trip and the country as a whole. Today I wanted to discuss geothermal and hydropower energy sources, as they are such an important energy sources in Iceland.

Disclaimer: I am not an expert, and this post was written from research I have done as well as my own experiences and things I witnessed during my recent trip to Iceland.

Iceland's unique formation and geology, as it is on the Mid-Atlantic ridge and is over a volcanic hotspot, makes it a perfect place to harness geothermal energy. Due to this source, Iceland is more energy independent from other countries, as it can produce a lot of energy without resources from other countries. This means that prices are also lower for Icelandic people, especially when it comes to heating their homes. This is something the tour guide on our trip told us about, and it was really interesting to hear from someone actually living in Iceland, and hear his experiences.

If Iceland was only to use geothermal energy, infrastructure would be an issue as many homes and small communities are completely isolated and very spread out, as I found out when I went there. There were so many lost little farmhouses and small clusters of houses in the middle of nowhere, and getting geothermal energy to them all would require a lot of infrastructure.

There is also a health implication. In Reykjavik, Hydrogen sulfide emitted from two nearby geothermal power plants has had a negative impact on residents' health. This is a negative of geothermal energy, and may impact how beneficial it actually is to use these sources.

However, Iceland also has a lot of possibility for hydropower, as it has many rivers, lakes and waterfalls. This has become another important source of renewable energy in Iceland. There are also, of course, issues with the use of hydropower.

In 2021, there were droughts in Iceland, leading to a shortage of water and the hydropower industry suffered greatly. This therefore caused a blip in electricity production, and overall this is an issue with the hydropower industry which is becoming increasingly apparent as we experience more droughts, and not only in Iceland.

The UNEP says in this article, that ...

Today, nearly 100 percent of Iceland's electricity comes from renewable sources, a transformation that has helped make its 366,000 people some of the wealthiest in Europe.

This is such a huge achievement. I did some other research and not all sources seemed to agree about exactly how much of Iceland's energy is renewable. It ranges between 75% and 100%, but even 75% percent is still amazing.

I really believe that each country needs to find the renewable resources that match their country, and for Iceland it makes so much sense to use primarily geothermal and hydropower sources.

I hope this has been interesting for you, and that you will consider visiting Iceland someday - it's such a beautiful country!!

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

Ozone layer

Hi everyone, What even is ozone? And the ozone layer? Where does the hole in the ozone layer come from and what does it mean? Is it dangerous? What can be done? Often the ozone-talk can be complicated and confusing, keeping an overview is hard and understanding all the problems always difficult. Let us break it down a bit for you: What is the ozone layer? We'll start with the basics: The ozone layer is part of the stratosphere, which is the second layer of the Earth's atmosphere, between 10 and 50 km above the Earth's surface and made up of protective gases. One of these protective gases is ozone. There is not much ozone in the atmosphere, only 0.3 molecule of ozone per 1 million molecules of air. This is because ozone is chemically unstable and only forms when ultra violet radiation (UV light) hits oxygen and breaks the bonds between the atoms. It fact it is so unstable that even when it has formed, it breaks down again relatively quickly. This leads to ozone turning back

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

Announcement: Animal of the week

02.08.2020 Animal of the week: Owl

Hi everyone, This week's blog post is all about owls. Habitat There are many different types of owl: barn owls, long-eared owls, snowy owls and lots more. Different species live in different places. Here are a few examples. Snowy owls live in the Arctic . Great grey owls live in pine forests. Elf owls live in deserts. There are about 130 different species of owl. Owls can be found everywhere in the world apart from Antarctica . Owls live in trees, holes in the ground, barns and caves. Most owls do not migrate in winter. Diet Owls eat insects, spiders, fish, reptiles, amphibians, birds and small mammals. What they eat the most depends on the type of owl and where it lives. Screech owls feed mostly on insects. Barn owls mainly eat mice, shrews and voles. Eagle owls eat hares and young foxes. Some owls can even fish like the Asian Fish Owl. Even though some species prefer a certain type of food, most owls will eat whatever they can find

10 Animals on the Edge of Extinction No. 10- The Javan Rhino

The Javan rhino is listed as the 1st animal on WWF’s list of the 10 world’s most endangered animals, and I for my part, had never heard of it! If you hadn’t either, we’re changing that now. A bit about the rhino’s lifestyle The Javan rhinos are now exclusively found on the island of Java in Indonesia, but were once found in vast regions of northeast india and Southeast Asia. They have a dark grey colour which looks almost black when wet, and their (often pink) skin folds look a bit like plated armor. Both males and females have lower incisors which resemble tusks that they use to fight. Males have one relatively short horn of about 25 cm (10 inches). Javan Rhinos live in tropical forests, marshy areas and in the thick bush. They are mainly browsers and eat over 100 plants species they find in the forest, weigh between 900 and 2300 kg (1984-5071 pounds) and are between 3 and 3.2 meters (10- 10.5 feet) long. How endangered are we talking? Javan rhinos are the most endangered animal s

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.

December Factfile

Hello, The fact file vote has come to an end and we have a winner. This year, we will be doing top tips. These will come out at the beginning of the month. These tips are, at the same time, challenges. We hope you will enjoy, and apply them! News Good news New hope for coral reefs A coral reef in India has been restored to health- the proof being in the noises the fish have been making. Many of these strange sounds have never been recorded before. This is amazing, especially considering that the reef has been devastated by blast fishing, where explosives are used to stun or kill everything in the area. Although the corals are being restored, scientists want to know if the animals are also returning and in what numbers. The Guardian states that 'Sound is vital for reef survival, because almost all of its inhabitants, from corals to crustaceans to fish, produce offspring that spend the early part of their lives in the open oceans, before us

How does plastic affect the environment?

Hello, I wanted to clarify exactly how plastic affects the environment. I hope this will explain. When plastic breaks, it releases toxic gasses that poison animals. Also, if plastic is swallowed it could cut or damage the inside of the animal. Many animals such as turtles and dolphins mistake the small plastic fragments for food. Even if the plastic is too small to cut into the insides of the animal or cause choking, too many micro plastics inside an animal will eventually block the digestive tracts and they will starve to death. Recent research proves that plastic has entered the human body. This is because plankton eats microplastics and small fish eat plankton. Bigger fish eat smaller fish and we eat the bigger fish. So inside us is plastic. Plastic also blocks waterways and sewers. This leads to the perfect breading grounds for disease carrying animals such as mosquitos. When plastic is burned it releases those toxic gasses

Linking climate change and inequality - 'The Great Carbon Divide'

Hey everyone, Have you heard of 'The great carbon divide‘? It is often referred to as the 'carbon footprint gap' or the 'emissions imbalance‘, and produces frightening numbers. The great carbon divide describes the huge gap between the amount of carbon dioxide the rich versus the poor emit, and these numbers shocked even us. What does this mean? There have been many different studies, and all of them show terrifying results. One study from the Guardian and Oxfam, reports that the richest 1% of the world's population emit more carbon than the poorest 66%. The richest 1% consist of 77 million people, which may seem like a lot at first, but the poorest 66% refers to over 5 billion people! Africa, which is home to 17% of the world's population, only causes 4% of the world's emissions. This top 1% emitted 16% of global CO2 emissions in 2019, that's 5.9 billion tonnes of CO2. Modelling suggests that it would take someone who isn't in the top 1% about 150
