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!!

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...

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 ...

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 ...

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...

The limits of the Earth - the planetary boundary model

Hi everyone, So today we're talking about a model that was introduced in 2009 and has offered a new perspective to thinking about environmental issues. The planetary boundary model has 9 boundaries, each has a safe zone. Once the safe zone is exceeded, the stable conditions on our planet are considered at risk, and there can be severe and possibly irreversible changes. The nine boundaries are considered separate however, they greatly affect each other. Novel Entities describes the introduction and accumulation of man-made novel chemical compounds. These include pesticides, nuclear waste and microplastics. Stratospheric Ozone Depletion refers to the depletion of the ozone layer which was a major problem in the 90s. Atmospheric Aerosol Loading is air particle pollution. Ocean Acidification is self-explanatory. The boundary Biochemical Flows is composed of two separate boundaries; nitrogen and phosphorus. Both of the ele...

29.11.2020 Animal Of The Week: Jaguar

Hello, Today (29th November) is world Jaguar day so this week our animal is the Jaguar. The Jaguar is an animal I know pretty much nothing about so I am going to learn a lot too! Jaguars (panthera onca) live for 12 - 15 years. Their heads and bodies are 150-180cm long and their tails are 70-90cm long! They weigh 45 - 110 kg. Habitat Jaguars live primarily in the Amazon Basin, though they can be found in smaller numbers in Central America. They once lived everywhere from central Argentina up to the southwestern United States but since the 1880s they have lost over half of their territory. They are mainly found in tropical rainforests but can live in savannas and grasslands. Diet They eat fish and turtles as they are actually quite competent swimmers as well as deer, iguanas, birds and monkeys; they will eat almost anything! Are they endangered? Jaguars are classed as near endangered and face several threats. South and Central Americ...

Energy comparison: Hydroelectricity

Hello everyone, Welcome back to another energy comparison post. Today we're talking about hydroelectricity. This is basically just using the power of moving water for our own uses. This idea has been around for thousands of years. The ancient Greeks and Romans used watermills to grind grains for making bread. Watermills were used up until the Industrial Revolution. What is hydroelectricity? There are three types of hydroelectric power plants. Impoundment facilities are the most common. The water is stored in a pool or reservoir normally located at a higher elevation. The dam uses gates or valves to control the water flow. When there is demand for electricity, the water is released. It falls downwards and turns turbines that turn the kinetic energy of the water (movement energy) into electric energy. Diversion facilities don't have a dam. They channel the water towards the turbines using a system of canals. Pumped-storage facilities are...
