Question

Which category would include hydroelectric power and other renewable sources of energy? A. coal B. petroleum C. natural gas D. other

Short answer

D. other

Step-by-step solution

Understand the Question

Read the question carefully. The question asks which category includes hydroelectric power and other renewable sources of energy.

Identify Renewable Sources of Energy

Renewable energy sources are those that can be replenished naturally. Common examples include solar power, wind power, hydroelectric power, geothermal energy, and biomass.

Evaluate Each Option

Look at each given option to determine whether it fits the category of renewable energy sources: A. Coal - Coal is a fossil fuel and is non-renewable. B. Petroleum - Petroleum is also a fossil fuel and is non-renewable. C. Natural Gas - Natural gas is another fossil fuel and is non-renewable. D. Other - This option can include renewable sources such as hydroelectric power.

Choose the Correct Answer

Based on the evaluation, the correct answer is option D, as 'Other' can refer to renewable energy sources including hydroelectric power.

Key concepts

hydroelectric power

Hydroelectric power is one of the most common types of renewable energy.
It involves generating electricity by using the kinetic energy of flowing water.
This method can be found in dams, where water is stored.
When water is released, it flows through turbines, spinning them to generate electricity. Hydropower is highly efficient and provides a continuous source of energy as long as there is flowing water.
It is a clean and sustainable option, but it does have some environmental impacts.
These can include changing river ecosystems and affecting fish migration.

alternative energy

Alternative energy refers to any energy source that is an alternative to fossil fuels.
This category includes a diverse range of energy sources that are renewable and cause less harm to the environment.
Examples include:

• Solar energy: Harnessing energy from the sun using solar panels.
• Wind energy: Using wind turbines to capture the kinetic energy from wind.
• Geothermal energy: Utilizing heat from the Earth's interior to generate electricity or provide direct heating.
• Biomass: Organic materials (such as plant and animal waste) used as fuel.
• Hydropower: Using the energy of moving water to generate electricity.

These sources are constantly replenished and can provide a sustainable, long-term energy solution while reducing greenhouse gas emissions.

education on renewables

Education on renewable energy is crucial for a sustainable future.
Understanding the various types of renewable energy helps us make informed decisions about our energy consumption.
Effective education programs should include:

• Basic concepts: Definitions and examples of renewable and non-renewable energy.
• Benefits: Why renewable energy is better for the environment and future generations.
• Practical applications: How renewable energy is used in real life.
• Hands-on activities: Experiments and projects that allow students to explore renewable energy sources.

Greater awareness and education can lead to increased adoption of renewable technologies, helping to combat climate change and pave the way for a sustainable future.
