Eneri: Renewable Energy Sources

What is renewable energy?

• Renewable energy is energy that is collected from resources that are naturally replenished on a human timescale.

• Renewable energy is energy that comes from non-renewable sources.

• Renewable energy is energy that contributes to pollution.

• Renewable energy is energy that depletes natural resources.

Name one example of a renewable energy source.

• Wind power

• Solar power

• Geothermal energy

• Hydropower

How does solar energy work?

• Solar energy is converted into electricity using photovoltaic cells.

• Solar energy is created by burning fossil fuels.

• Solar energy is generated by wind turbines.

• Solar energy is produced by nuclear reactions.

What is the difference between renewable and non-renewable energy sources?

• Non-renewable energy sources are better for the environment than renewable sources.

• Renewable energy sources are limited in supply, while non-renewable sources are abundant.

• Renewable energy sources can be replenished naturally, while non-renewable energy sources cannot.

• Renewable energy sources are more expensive than non-renewable sources.

Why is wind energy considered a clean source of energy?

• Wind turbines are noisy and disrupt wildlife habitats.

• Wind energy is clean because it does not produce greenhouse gas emissions or air pollutants during operation.

• Wind energy produces toxic waste that harms the environment.

• Wind energy is unreliable and cannot meet energy demands.

What are the benefits of using hydropower as a renewable energy source?

• Hydropower is not a reliable source of energy

• Hydropower causes air pollution

• Hydropower is expensive to implement

• Hydropower offers benefits such as low greenhouse gas emissions, reliable power generation, flood control, and water supply management.

Explain how geothermal energy is harnessed.

• By extracting energy from ocean waves

• By drilling wells into the Earth's crust to access hot water and steam, which are used to drive turbines connected to generators.

• By capturing sunlight using solar panels

• By harnessing wind energy through turbines

What are the environmental benefits of using biomass as an energy source?

• Increases greenhouse gas emissions

• Reduces greenhouse gas emissions, promotes waste management, supports sustainable land use

• Harms waste management efforts

• Promotes unsustainable land use

How can we increase the use of renewable energy sources in our daily lives?

• By not investing in renewable energy companies

• By installing solar panels, using energy-efficient appliances, reducing energy consumption, supporting renewable energy policies, and investing in renewable energy companies.

• By using more fossil fuels

• By ignoring renewable energy policies

What are some challenges associated with the widespread adoption of renewable energy sources?

• Intermittency, high initial costs, energy storage limitations, grid integration issues

• Ease of implementation

• Low maintenance costs

• Consistent energy production
