Review Questions

• How do energy storage technologies facilitate the integration of renewable energy sources into the power grid?
  • Energy storage technologies play a vital role in integrating renewable energy sources by capturing excess energy generated during high production periods, such as sunny or windy days. This stored energy can then be used during times of high demand or when renewable sources are not producing electricity. By balancing supply and demand, these technologies help ensure a stable and reliable electricity supply, making renewable energy more viable as a primary power source.
• Evaluate the different types of energy storage technologies available today and their potential impact on renewable energy adoption.
  • There are several types of energy storage technologies, each with unique advantages. Batteries, particularly lithium-ion types, offer rapid response times and are versatile for various applications. Pumped hydro storage is effective for large-scale needs but requires specific geographic conditions. Compressed air and thermal storage systems also provide valuable options for grid management. The diversity in these technologies allows for tailored solutions that enhance the adoption of renewables by addressing specific challenges related to energy intermittency and reliability.
• Synthesize the future trends in energy storage technologies and their implications for global energy sustainability efforts.
