As a place experiences processes of development its desired sources of energy changes due to the amount and stability required. There is a huge amount of geopolitical power involved in controlling energy. Being energy poor makes a country vulnerable. There are many possibilities associated with the changing availability of energy (as reserves dwindle), due to technological innovation in the production, transfer and storage of energy as well as the increasing demand for sources that involve less carbon release.
CO2 / carbon release (low and high carbon release)
Man made climate change or anthropogenic
Low carbon power
Energy grid
Energy storage
Green technology
Define the key terms above using your 'Geography for the IB Diploma Study and Revision Guide' by Simon Oakes and the useful links below.
As you are getting very used to doing we need to describe our energy consumption before we can begin to explain why the changes have happened and begin to explore practical plans for the future.
Using image one, describe the global trend in the consumption of different forms of energy.
Using image two, describe the trend in the number of people with and without electricity.
Using image three, describe the pattern in energy consumption between regions in 2025.
We are currently hugely dependent on hydrocarbons for our energy sources but what has led to this?
Read the article below from the 'Our World in Data' website and suggest why you think that there has been a general increase in the use of fossil fuels energy. Think back to your prior lessons and you can also look in the Simon Oakes text book (Pages 93-95) for help.
As you have just done for the fossil fuels you will need to describe the changes in the use of nuclear energy and then suggest reasons for the change. Think about the natural disasters which may have also had an impact on nuclear energy use.
The final area to focus on is to look at the changes in the use of renewable energy. "In 2025 renewables (33.8%, 10,730 TWh) overtook coal (33.0%, 10,476 TWh) in global electricity generation for the first time in the modern era. Coal fell below a third of generation for the first time in history. Solar grew by a record 636 TWh to 2,778 TWh, up 30%. Solar and wind together met 99% of global demand growth." AI Generated. Describe the global changes and then suggest reasons for the changes.
Now that you know the changes in energy use and why the changes have been happening it is important to link it to the Sustainable Development Goals (SDGs). After all "Around 2.1 billion people, a quarter of the world, cook on open fires or inefficient stoves. Household air pollution caused an estimated 2.9 million deaths in 2021, including over 309,000 children under five. 923 million people in sub-Saharan Africa lacked clean cooking access in 2022. Women and children carry the greatest burden." AI summary. For safe and clean energy sources this refers to SDG Goal 7.
Why is this SDG focusing on energy?
Why do we need to provide modern energy in lower income countries?
Watch the youtube clip below and create a detailed example of how clean cook stoves could change lives.
Describe the changing importance of oil as an energy source. [2]
Explain two reasons for the changing importance of ONE named energy source. [2+2]
