Meeting energy demands (Edexcel GCSE Geography A): Revision Notes
Meeting energy demands
Introduction to energy resource management
Managing our energy resources sustainably has become one of the most pressing challenges of our time. Both renewable sources (like solar and wind) and non-renewable sources (such as fossil fuels) require careful planning and management to meet the world's increasing energy needs. However, this management process involves many different groups of people who often hold contrasting views about the best approaches to take.
Key exam focus: You may need to study either energy resource management OR water resource management for your exam - make sure you focus on whichever one your course covers.
Why do we need to manage energy resources?
There are several critical reasons why energy resource management has become essential in today's world.
Climate change concerns represent one of the most significant drivers for better energy management. Research indicates that our continued reliance on fossil fuels could result in permanent environmental damage through climate change. This has pushed scientists and policymakers to seek more sustainable alternatives.
Growing population and economic development create another major challenge. As countries develop economically and populations increase worldwide, governments face mounting pressure to boost energy supply from renewable sources to meet rising demand.
Individual environmental impact can be measured through concepts like ecological and carbon footprints. These tools help us understand how much environmental impact each person creates through their energy consumption. In the UK, people have an ecological footprint that is 4-5 times larger than the global average, highlighting the significant impact of energy use in developed countries.
Understanding Ecological Footprints
An ecological footprint measures how much biologically productive land and water an individual, population, or activity requires to produce the resources it consumes and to absorb the waste it generates. This measurement helps us understand our environmental impact compared to what the Earth can sustainably provide.
Different perspectives on energy management
The challenge of managing energy resources becomes more complex because different groups hold varying views on how best to approach this issue.
Individual viewpoints
People's attitudes towards energy management vary considerably based on their personal circumstances and priorities.
Many individuals now support using energy-efficient products and generating renewable energy at home, such as installing solar panels on their roofs. This represents a growing awareness of environmental responsibility at the household level.
However, some people believe that renewable energy technologies remain too expensive and prefer not to face higher energy bills. This economic concern often influences personal energy choices.
Additionally, people living near proposed renewable energy developments (like wind farms or solar parks) sometimes express concerns about noise pollution and visual impact on their local environment. These 'not in my backyard' attitudes can create challenges for renewable energy expansion.
NIMBY Attitudes Explained
NIMBY stands for "Not In My Back Yard" - a phenomenon where people support renewable energy projects in principle but oppose them when they're planned for their local area. This creates a significant challenge for expanding renewable energy infrastructure.
Organisational perspectives
Companies and other organisations often approach energy management from a business perspective, balancing environmental responsibility with financial considerations.
Many organisations recognise the importance of managing their operations more sustainably, sometimes advertising these efforts as part of their public relations strategy to improve their corporate image.
However, increased operating costs can present challenges, particularly for smaller companies that may struggle to afford expensive energy-efficient technologies or renewable energy systems.
Corporate Energy Management: McDonald's Initiatives
McDonald's provides an excellent example of corporate energy resource management. The company has implemented several sustainability measures including:
- Biodiesel conversion: Replacing cooking oil from restaurants with biodiesel for their delivery lorries
- LED lighting upgrade: Upgrading from traditional neon and filament bulb lighting to more efficient LED lighting systems
These changes demonstrate how large corporations can reduce their environmental impact while potentially saving money on energy costs over time.
Government approaches
Governments play a crucial role in energy resource management through policy-making and international cooperation.
International cooperation has become increasingly important, with world leaders' conferences establishing shared targets and measures for sustainability. A significant milestone occurred at the UN Climate Change Summit in 2015, where the UK joined 195 other nations in pledging to limit global temperature increases to 2°C. This commitment includes investing in new low-carbon energy technologies.
National and local policies are being developed to encourage citizens to adopt more sustainable transport systems. Many countries are introducing measures such as congestion charging schemes and promoting bicycle use to reduce energy consumption from transport.
The Paris Agreement Impact
The 2015 UN Climate Change Summit resulted in the Paris Agreement, which has become the foundation for global climate action. The 2°C temperature limit represents a critical threshold - beyond this point, scientists warn of irreversible and catastrophic climate impacts.
Understanding the fracking debate
The issue of fracking (hydraulic fracturing) for shale gas extraction perfectly illustrates how different groups can hold conflicting views on energy resource management.
Individual opposition often focuses on environmental concerns. Many people protest against shale gas exploitation due to its potential environmental impacts, including water contamination, air pollution, and increased seismic activity.
Organisational support typically emphasises economic benefits. Some organisations view fracking in the UK as financially beneficial, arguing it could generate income for the energy industry and create jobs, while receiving support from the UK government.
Pressure group activism adds another dimension to the debate. Environmental organisations like Greenpeace actively oppose fossil fuels, fracking, and nuclear energy, advocating instead for energy production through renewable sources such as sunlight, wind, waves, tides, and geothermal heat.
Critical Sustainability Perspective
Some people and pressure groups argue that fracking is not sustainable because shale gas reserves will only last approximately 70 years and are non-renewable, meaning they cannot be replaced once used. This raises important questions about whether short-term economic benefits justify long-term environmental risks.
Key Points to Remember:
- Energy resource management involves balancing environmental sustainability with economic and social needs
- Different groups (individuals, organisations, governments) often have conflicting views on the best approaches to energy management
- Individual ecological footprints in the UK are 4-5 times larger than the global average, highlighting the need for better energy management
- International cooperation, such as the 2015 UN Climate Change Summit agreement to limit temperature rises to 2°C, is essential for addressing global energy challenges
- Real-world examples like McDonald's energy initiatives and the fracking debate demonstrate the practical complexities of implementing sustainable energy management
