Summarize Written Text Question #1: Renewable Energy and Grid Integration
Text for Summarizing:
Integrating renewable energy sources such as wind and solar power into traditional power grids presents both opportunities and challenges. Renewable energy is clean and abundant, reducing greenhouse gas emissions, but its variability—due to changing weather conditions—can affect the stability of the power supply. Advances in grid infrastructure, including smart grids and energy storage systems, are needed to manage unpredictability and maintain reliability in electricity supply. Furthermore, cooperation between governments and energy companies is crucial to enhancing grid flexibility while minimizing the economic costs associated with the transition to cleaner energy.
Instructions: Summarize the passage in one sentence.

Summarize Written Text Question #2: Grid Stability and Renewable Energy
Text for Summarizing:
The introduction of renewable energy is transforming the global energy landscape, presenting new challenges for grid stability. Solar and wind energy are less predictable than traditional forms of energy, which can cause voltage fluctuations and outages if not managed properly. To accommodate these changes, power grids must be more adaptive by using technologies like smart meters, advanced energy storage systems, and real-time monitoring. Moreover, policy-makers play a critical role in ensuring that regulations are updated to support renewable integration and incentivize investment in technological upgrades.
