Step 1
Suggest reasons for the different methods of energy production around the world.
Answer
Countries employ various methods of energy production due to a combination of geographic, economic, and social factors.
-
Natural Resources Availability: Countries rich in specific natural resources tend to rely heavily on those for energy production. For example, Saudi Arabia extensively uses oil due to its vast reserves, while Brazil utilizes hydropower due to abundant rainfall and river systems.
-
Economic Considerations: The cost of energy production affects a country's choice of energy sources. Countries like China and India have invested in coal due to its relatively low cost and domestic accessibility.
-
Technological Capability: Advanced nations possess the technology to harness various energy forms efficiently. For example, Russia's reliance on nuclear energy is supported by their technological infrastructure for nuclear power production.
-
Environmental Policies: Countries with strict environmental regulations may invest in renewable sources like wind or solar energy. For instance, New Zealand has significantly developed its hydropower capabilities, aligning with its commitment to sustainability.
Step 2
Discuss the advantages and disadvantages of any non-renewable source of energy you have studied.
Answer
I will discuss the advantages and disadvantages of coal as a non-renewable energy source in China.
Advantages:
- Abundant Supply: China has significant domestic coal reserves, which reduces reliance on imports, ensuring energy security.
- Cost-Effectiveness: The low cost of coal mining and conversion enables cheaper electricity generation, benefiting the economy.
- Established Infrastructure: China has a well-developed infrastructure for coal extraction and distribution, facilitating energy production.
Disadvantages:
- Environmental Impact: Coal combustion is a major source of greenhouse gases, contributing to air pollution and climate change.
- Health Risks: Air pollution from coal power plants poses severe health risks, leading to respiratory diseases among the population.
- Finite Resource: As a non-renewable resource, reliance on coal is unsustainable long-term, driving the need for cleaner energy alternatives.
