Non-renewable Energy Sources

Introduction

• Non-renewable energy sources are finite and unsustainable sources of energy.
• They have been a primary source of energy since the Industrial Revolution.

Historical Perspective

• Dependence on fossil fuels, such as coal, oil, and gas, escalated during the Industrial Revolution.
• These fuels powered the rapid industrialisation of the 18th and 19th centuries.

Global Energy Consumption (2012)

• In 2012, approximately 82% of global energy consumption came from non-renewable fossil fuels.
• This high dependence on finite resources raises concerns about long-term sustainability.

Types of Non-renewable Energy

• Non-renewable energy sources include coal, oil, and natural gas.
• These fuels are burned to generate electricity, heat, and power various industries.

The Pie Chart (2014)

• A pie chart from 2014 illustrates the types of energy sources used worldwide.
• It highlights the significant contribution of non-renewable energy sources.

The UK's Primary Energy Use

• The UK, like many countries, relies heavily on non-renewable energy sources for its primary energy needs.
• This includes electricity generation, transportation, and heating.

Non-renewable Energy Sources

Finite Stock and Depletion

• Non-renewable energy sources are finite, meaning they will eventually run out.
• As they deplete, extracting and using them becomes more challenging and costly.

Environmental Impact

• The burning of non-renewable fuels releases greenhouse gases, contributing to climate change.
• Extraction processes can also harm ecosystems and landscapes.

Transition to Renewable Energy

• There is a global shift towards renewable energy sources to reduce reliance on non-renewables.
• This transition aims to mitigate environmental impacts and ensure a sustainable energy future.
