Y7U5T8 - Exploring Alternative Energy Sources

What are renewable energy sources?

• Energy sources that are replenished naturally

• Energy sources derived from burning fossil fuels
• Energy sources that are non-renewable and harmful to the environment
• Energy sources that generate a lot of emissions
• Energy sources that are used in traditional ways

What are the advantages and disadvantages of solar energy?

• Advantages: Renewable, doesn't produce emissions; Disadvantages: Requires a lot of space, not effective in areas with low sunlight
• Advantages: Produces a lot of energy, doesn't harm aquatic life; Disadvantages: Requires a large amount of water, not renewable
• Advantages: Renewable, reduces carbon footprint; Disadvantages: does not work at night

• Advantages: Doesn't produce emissions, reduces carbon footprint; Disadvantages: Requires a lot of space, not renewable
• Advantages: Produces a lot of energy, reduces carbon footprint; Disadvantages: Can harm aquatic life, requires a large amount of water
