Question

1. explain the difference between renewable and nonrenewable energy sources.
2. why are fossil fuels considered nonrenewable?
3. give two advantages and two disadvantages of using renewable energy sources. advantages:

Explanation:

1. Renewable energy sources can be replenished naturally in a relatively short - time, like solar and wind. Non - renewable energy sources are finite and take a long time to form, such as coal and oil.
2. Fossil fuels are formed over millions of years from the remains of ancient organisms. At the rate we consume them, they cannot be replenished within a human - relevant time frame.
3. Advantages of renewable energy: They are sustainable and do not deplete. They also generally produce less pollution. Disadvantages: They can be intermittent (e.g., solar doesn't work at night), and the initial infrastructure costs can be high.

Answer:

1. Renewable energy sources are naturally replenished over a short time, while non - renewable energy sources are finite and take a long time to form.
2. Fossil fuels take millions of years to form and are consumed much faster than they can be replenished.
3. Advantages: Sustainability, less pollution. Disadvantages: Intermittency, high initial costs.
