Emerging Countries: These nations have large populations and rapid economic growth, leading to a significant increase in energy demand. Emerging countries like China and India predominantly use fossil fuels such as coal, oil, and natural gas.
Developing Countries: These nations primarily rely on traditional energy sources like biomass and firewood due to factors such as underdevelopment, insufficient energy technology, and low energy efficiency. African and South Asian countries are examples of developing nations with lower per capita energy consumption.
Fossil fuels remain the primary global energy source, but the proportion of renewable energy such as solar, wind, and hydro is gradually increasing in some regions due to growing environmental awareness.
Different Types of Energy and Their Usage Proportions
Energy can be divided into two major categories: fossil energy and non-fossil energy.
Fossil Energy: Mainly composed of coal, oil, and natural gas, these resources are extracted from underground, also known as mineral energy. According to the International Energy Agency (IEA) data, in 2019, the global energy consumption comprised 27% coal, 32% oil, and 24% natural gas.
Renewable Energy: Includes solar, wind, hydro, biomass, etc., sourced from nature without causing pollution, often referred to as green energy. IEA data indicates that in 2019, renewable energy accounted for 11% of global energy consumption.
Nuclear Energy: Derives from the nuclear fission process in reactors, offering high power efficiency and low emissions. However, nuclear waste management and safety remain significant concerns. In 2019, global nuclear energy usage was 4%, according to IEA.
Fossil fuels continue to dominate the world’s energy sources, but as environmental awareness rises and renewable energy technology advances, the proportion of renewable and non-fossil energy sources is gradually increasing.
The Impact of Energy Consumption on the Environment
The environmental impact of energy consumption manifests in various ways:
Greenhouse Gas Emissions: The combustion of fossil fuels, such as coal and oil, releases significant amounts of carbon dioxide (CO2) and methane, contributing to global warming, rising sea levels, and severe climate change issues.
Air Pollution: Pollutants like nitrogen oxides, sulfur oxides, and particulate matter generated from fossil fuel combustion can affect air quality, leading to respiratory and cardiovascular diseases.
Water Resource Depletion: Energy production requires substantial water resources for activities like fuel extraction and cooling. In water-scarce regions, these activities exacerbate water scarcity issues.
Ecological Damage: Energy production activities, such as coal mining and hydropower dam construction, can disrupt ecosystems, causing vegetation loss and affecting natural river flow and fish migration.
Root Causes of Energy Issues
- Rapid Growth in Energy Demand
The rapid increase in the world’s population is expected to reach 9 billion by 2050, leading to a substantial rise in energy demand.
The acceleration of modern industrialization and urbanization processes continues to escalate the demand for energy, with various structures, industrial facilities, and transportation requiring substantial energy consumption.
As global economic development progresses, the demand for energy continues to rise, closely correlating energy consumption with national economic growth.
The singular structure of energy consumption also results in an excessive reliance on certain types of energy, with fossil fuels maintaining a high proportion in global energy consumption.
The rapid growth in energy demand is a primary root cause of energy issues, progressing alongside the development and advancement of human society.
- Limited and Depleting Nature of Energy Resources
The finite and depleting nature of energy resources is another major root cause of energy issues.
Limited reserves of energy resources: Fossil fuels such as oil, natural gas, and coal are currently the primary energy resources, with limited reserves. As consumption increases, the extraction and utilization costs of these resources will continually rise.
Increased difficulty in resource extraction: The extraction of most fossil fuel resources requires operations in challenging environments like deep-sea locations, deserts, and other harsh conditions. These areas incur high extraction costs and pose safety and environmental concerns.
Depletion of energy resources: Most major energy resources are nearly non-renewable. When these resources are depleted, energy shortages become an imminent problem.
Geopolitical impact of energy resources: Due to certain countries possessing abundant energy resources, unfair competition exists in the extraction and utilization of these resources.
- Monopoly and Price Volatility in the Energy Industry
Monopoly in the energy industry: The global energy market is characterized by large energy enterprises occupying a considerable market share, leading to a monopolistic phenomenon. This monopoly results in unfair competition and excessively high prices in the energy market.
Price volatility in energy: Due to the energy industry’s monopoly, large energy enterprises can manipulate supply and demand to control energy prices. This manipulation leads to unstable and fluctuating energy prices, impacting both the stability of the energy market and global economic development.
Unstable energy supply: Concentration of energy resources in a few countries results in instability when these countries undergo political or economic changes, affecting the stability of global energy supply.
Geopolitical impact of energy: Unequal distribution of energy resources globally leads to competition and conflicts among countries and regions. This competition may escalate into conflicts and wars, further disrupting the stability of the global energy market.
- Pollution and Ecological Damage
One of the root causes of energy issues is the pollution and ecological damage caused by energy production and usage.
Traditional energy sources such as coal and oil emit large amounts of harmful substances like carbon dioxide, sulfur dioxide, and nitrogen oxides during production and usage. These substances pollute the air, water, soil, and the environment. The extraction and processing of traditional energy sources consume significant energy, leading to resource depletion and environmental degradation.
While new energy sources like wind and solar are relatively environmentally friendly, their production and usage still have an impact. For instance, the production of solar panels requires substantial energy and chemicals, contributing to pollution. The development and usage of energy industries also have a considerable impact on the natural ecological environment, causing issues like large-scale land development, excessive water consumption and pollution, and damage to ecosystems.
