Question

Which of the following is considered a renewable energy resource? A. coal-fired power plants B. hydroelectric power C. natural gas D. nuclear power

Short answer

B. Hydroelectric power

Step-by-step solution

- Understand Renewable Energy

Renewable energy comes from resources that can be replenished naturally within a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.

- Identify the Options

The given options are: A. coal-fired power plants, B. hydroelectric power, C. natural gas, D. nuclear power.

- Analyze Each Option

A. Coal-fired power plants rely on coal, a non-renewable resource. B. Hydroelectric power uses flowing water, which is a renewable resource. C. Natural gas is a fossil fuel and non-renewable. D. Nuclear power relies on uranium, which is non-renewable.

- Select the Correct Answer

Based on the analysis, hydroelectric power (option B) is the only renewable energy resource among the given options.

Key concepts

hydroelectric power

Hydroelectric power is a form of renewable energy that harnesses the energy produced by flowing water. This method typically involves the construction of dams on large rivers. When water is released from the reservoir behind a dam, it flows through turbines, generating electricity.
One of the biggest advantages of hydroelectric power is its ability to provide a consistent and reliable source of energy. Since it relies on water cycles that are naturally continuous, it is a sustainable and long-term solution.
Here are a few important points about hydroelectric power:

• It does not produce direct greenhouse gas emissions, making it environmentally friendly.
• Hydropower plants can also provide flood control, irrigation support, and clean drinking water.
• While the initial construction can be costly and may impact local ecosystems, the operational costs are relatively low.

natural resources

Natural resources are materials or substances found in nature that can be used for economic gain or to produce energy. They include minerals, forests, water, and fossil fuels like coal, oil, and natural gas.
These resources are classified into two main categories: renewable and non-renewable.

• Renewable resources: These can be replenished naturally within a human lifespan. Examples include sunlight, wind, and water.
• Non-renewable resources: These are available in finite quantities and take millions of years to form. Examples are coal and oil.

Relying on non-renewable resources poses sustainability issues because they can deplete over time. Conversely, renewable resources offer a more sustainable approach to energy production and consumption.
Controlled utilization and technological advancements can improve the efficiency and sustainability of both types of natural resources.

sustainable energy

Sustainable energy refers to the use of energy sources that meet current demands without compromising the ability of future generations to meet their own needs. It emphasizes the importance of using renewable resources efficiently and responsibly.
There are several benefits to using sustainable energy:

• It reduces greenhouse gas emissions and mitigates the impact of climate change.
• It promotes the conservation of natural resources and reduces dependency on finite resources like fossil fuels.
• Investment in sustainable energy can create jobs and stimulate economic growth in various sectors.

Key sustainable energy sources include solar, wind, and hydroelectric power.
These sources are renewable and have minimal environmental impact. The integration of sustainable energy with cutting-edge technology and infrastructure can pave the way to a cleaner and more resilient energy future.
