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!!

Ecotourism: what it is, the advantages and the disadvantages

Hi Everyone! Today we wanted to talk about the idea of ecotourism, including the advantages and disadvantages of this concept. If you are looking to reduce your environmental and social impact when travelling, then this is the post for you! Ecotourism is a form of tourism which limits the damage to the environment and local community. It can involve helping in community projects such as planting trees, as well as taking part in local customs and festivals. It helps to keep the local culture alive, while preserving the natural environment. The advantages are abundant. By helping in a project conserving the environment, tourists gain a new understanding and appreciation for the natural world and may be inspired to make changes in their "real" life to live more sustainably. It provides a valuable insight to a country and community, perhaps also inspiring more respect for different people and the lives they lead. The projects also provide sustainable income sources for locals, h...

Air pollution

Hi Everyone, Today we're talking about air pollution. We've all heard about air pollution, normally in connection to cars, coal mines or planes. But what are the consequences of too much air pollution and what can we do about it? One type of air pollution is known as PM2.5. These are particles less than 2.5 micrometers in diameter. This means that we cannot see them without technology such as microscopes. They are produced in a number of different ways including power generation, motor traffic, domestic heating and chemical reactions taking place in the air around us. Although these particles are very small and "invisible", they can cause a lot of damage. Research data now shows links between this form of air pollution and cancers, premature births, diabetes (especially type 2) and heart and lung disease. It is shown to cause 400 000 deaths across Europe every year. Unfortunately this form of air pollution is widespread. A guardian article explains how in Europe alone...

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...

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 ...

Green Pets: meet two new additions to my house plant family

Hi Everyone! This is a bit of a shorter post today but I have two new house plants! I love my new green pets so today I wanted to share them with you! >Neither of them have names yet so any suggestions welcome and appreciated :) Pilea: I love my new Pilea! My mum has one and managed to grow another from it and gave it to me. I also put it in a pot which originally had my Aloe Vera in it, but it grew too big! Anyway, I'm so glad my Pilea could find a home in it! I love the way this plant looks and it makes me very happy to look at! I actually don't know the name of the second one - I will insert it when I have found it! I got this one from my aunt in France who has one and made a cutting for me. I'm not sure if it'll survive but we'll see - it's certainly well-travelled! I'm not giving up hope yet and even if it doesn't make it she said she could cut me a new one! I will update on this ...

The life of ... a koala

Hello everyone, Today we're talking about koalas. Also known as koala bears, koalas are marsupials. So they're actually not bears. Koalas, phascolarctos cinereus , are tree dwelling and probably best known for spending most of the day sleeping. They live for up to 15 years in the wild although captive koalas generally live for longer. Koalas have a stout, gray body and a cream-coloured chest. They have a broad face, small yellow eyes and big fluffy ears. In adaptation to climbing, their feet are strong and clawed. Adult individuals in South Australia weigh 14kg and are 60-84cm big. Their Eastern cousins are considerably smaller. Koalas are found in Eastern and Southern Australia, where they live in eucalyptus trees. They feed on the leaves of these eucalyptus trees, eating up to 1.3kg a day. With a body weight of up to 14kg, this means they eat just under 10% of their body weight every single day. However, the le...

Evolution

Hi, So today, I am going to talk about evolution. We have mentioned this before in our Galapagos Ecosystem series but we’ve never gone over exactly what it is. So before Charles Darwin thought of his theory of evolution, the majority of people in Europe thought that all species were unrelated and that humans were not related to animals. This was mostly based on Christianity. Darwin studied hundreds of different species and on the Galápagos Islands , he first started to form his theory of evolution. Darwin's theory of evolution by natural selection, as it was later called, is best explained by the example of the giraffe. Let's assume that giraffes have short necks (as they did many centuries ago). Now a mother has two children. By chance, one has a slightly longer neck. This is a coincidence. As the giraffes feed on the lower leaves of the trees, these slower disappear. There aren't enough leaves for the giraffes. Thus the giraffe wi...

Sustainable food choices challenge

Hi everyone, Welcome back to our second challenge! Today we're talking about sustainable food choices. 1. No meat on Mondays challenge The production of meat, especially beef, is resource-intensive and contributes significantly to deforestation, greenhouse gas emissions, and water pollution. By dedicating one day a week to plant-based meals, you can decrease your carbon footprint and help to reduce the strain on natural resources. This challenge encourages a more sustainable and ethical approach to food consumption, gaining a better understanding of the environmental impact of meat production. Reducing meat intake is also associated with health benefits, including lower risks of heart disease and certain cancers, making it a win-win for both your personal well-being and the planet. 2. Local / seasonal eating challenge Choosing local and seasonal foods is important in helping to reduce the environmental impact of food production and transporta...

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...
