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!!

Ecosia

We all need to do something to save our planet: it is no use just leaving it to Greta Thunberg! She is very inspirational, yes, but she can only do so much. She isn't superhuman! The climate crisis is up to us; up to you. We all have to get stuck in. Research, learn, discover and most importantly: never give up! The world's animals need us. The world's trees need us and a simple way to do this is to switch to Ecosia. Ecosia is a search engine but it plants trees while you search the web. Okay, it doesn't have as many websites as google so you may want to have google as a backup but it plants trees: this is your opportunity to make a simple change. Just google Ecosia and search to plant trees. Make a difference. Image: This image is owned by Binyamin Mellish on pexels.com .

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...

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...

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...

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 ...

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 ...

Maldives - the direct impacts of climate change

Welcome back, Today we’re looking at the direct impacts of the climate crisis . The main reason why people don’t believe in climate change is that they can’t see it with their own eyes. So, we’re going to have a look at the Maldives where the effects of climate change become more obvious with every passing year. Maldives The full name of the Maldives is The Republic of the Maldives. It is an independent country made up of about 1 200 islands in the North Indian Ocean. The northernmost island is situated 370 miles away from the mainland (India). The islands are actually the tips of an ancient volcanic mountain range that is now almost completely submerged. In fact, the highest point is 1.8m-2.4m above sea level with the average elevation being 1m above sea level. The islands have a large tourism industry, due to the stunning nature found on and around the islands. 500 000 - 1 500 000 tourists visit the islands each year. This is mainly 'nature to...

August 2021 Factfile - some news, animals and a plant

Welcome to our August factfile, News Bad news :( Fires in and around Athens Athens has been under siege this month, but not by any army. The forests all around the capital and in other parts of Greece and Turkey have gone up in flames. Houses have been destroyed and thousands have been evacuated. The reason is, of course, climate change . “It’s been crazy over here. Between the extreme heat and the wildfires, it feels apocalyptic,” Eleni Myrivili wrote in an email on Thursday as the army was deployed to assist firefighters. “Ash is raining down on us here in Athens.” England's lake district in peril Lake District, a popular holiday resort in the north of England, is now eroding faster as a result of climate change and an increased amount of walkers due to the pandemic. Paths that were once two meters wide are now at least 12 meters wide on some walks. Also visitors tend to walk off the path, endangering local wildlife. With...

Ways to help make your household environmentally friendly

We have told you a bit about the problems that the environment is facing in previous posts but we haven’t told you how to help the environment around the house. You don’t even need a garden to make a difference! Ways to help stop global warming Tip 1: Turn the lights off when you leave a room. Tip 2: Walk or cycle on short journeys. Tip 3: Don’t have the windows open and the heaters on at the same time. Tip 4: Never leave your engine running Tip 5: If you can, buy an electric car as these produce less Co2. Ways to help stop plastic pollution Tip 1: Buy a water bottle. It seems simple but every year the UK uses an estimated 13 billion plastic bottles. Tip 2: Use a bar of soap and a bar of shampoo instead of shower gel and bottled shampoo. Some say soap can dry your skin out but if you do your research you can find plastic-free high-quality soap, perhaps at a price but it depends on where you get it from. Tip 3: Make...
