Thermal expansion can cause big problems for renewable energy technologies. Here are a couple of examples:

• Solar Panels: They can bend or change shape when the temperature changes, which can make them less effective.
• Wind Turbines: Changes in temperature can lead to serious damage to their structure.

To tackle these problems, we can use a few helpful strategies:

1. Choose the Right Materials: Pick materials that can handle expansion well.
2. Smart Designs: Use flexible connections so parts can move with temperature changes.
3. Regular Check-Ups: Keep an eye on the systems and make adjustments based on how they handle heat.

These steps can make renewable energy systems more reliable, even when thermal expansion is in play.
