Energy and Sustainability

What is renewable energy?

• Renewable energy is energy that depletes over time.

• Renewable energy is energy derived from natural resources that replenish themselves over time.

• Renewable energy is energy that harms the environment.

• Renewable energy is energy derived from non-renewable sources.

Give an example of a non-renewable energy source.

• Solar power

• Wind energy

• Hydropower

• Fossil fuels

Explain the relationship between matter and energy.

• E=mc^2

• Matter and energy have no connection

• Energy is not equivalent to mass

• Matter is not related to energy

How does solar energy contribute to sustainability?

• Solar energy is harmful to the environment

• Solar energy depletes natural resources

• Solar energy is expensive and unaffordable

• Solar energy is renewable, clean, and reduces greenhouse gas emissions.

Differentiate between potential and kinetic energy.

• Potential energy is stored energy, while kinetic energy is energy in motion.

• Potential energy is the energy of motion, while kinetic energy is the energy of position.

• Potential energy is energy in motion, while kinetic energy is stored energy.

• Potential energy is only present in living organisms, while kinetic energy is present in non-living objects.

Why is wind energy considered a clean source of energy?

• Wind energy is not a renewable source

• Wind energy releases harmful chemicals into the atmosphere

• Wind energy does not produce greenhouse gas emissions or air pollutants during operation.

• Wind turbines are noisy and disrupt wildlife

Discuss the concept of energy conservation.

• Energy conservation only applies to mechanical systems.

• Energy conservation states that energy can be created and destroyed at will.

• Energy conservation is the principle that energy cannot be created or destroyed, only transformed from one form to another. This means the total energy in a closed system remains constant over time.

• Energy conservation violates the laws of thermodynamics.

What are the advantages of using hydroelectric power?

• Expensive to build

• Renewable, minimal greenhouse gases, reliable power generation, flood control, irrigation

• High maintenance costs

• Limited to areas with water resources

How can geothermal energy be harnessed for sustainable practices?

• Geothermal energy is collected through solar panels

• Geothermal energy is harnessed by burning fossil fuels

• Geothermal energy can be harnessed through geothermal power plants that utilize steam or hot water from underground reservoirs to generate electricity.

• Geothermal energy is extracted from wind turbines

Explain the importance of reducing energy consumption for sustainability.

• Reducing energy consumption has no impact on sustainability

• Reducing energy consumption is important for sustainability because it helps conserve natural resources, reduce greenhouse gas emissions, mitigate climate change, and promote energy efficiency.

• Increasing energy consumption is better for the environment

• Energy consumption does not affect natural resources or climate change
