Yes, solar energy is renewable because it is derived from the sun, which is a virtually limitless source of energy. The sun's energy is constantly being replenished and will continue to do so for billions of years. This makes solar energy a sustainable and renewable source of power that can be harnessed for electricity generation and other applications. **

Renewable resources and sustainable resources are related concepts but not exactly the same. Renewable resources are those that can be replenished naturally over time, such as sunlight, wind, and water. Sustainable resources, on the other hand, refer to resources that are managed in a way that meets current needs without compromising the ability of future generations to meet their own needs. While renewable resources are often considered sustainable, not all sustainable resources are necessarily renewable, as some non-renewable resources can be managed in a way that ensures their long-term availability. **

Without knowing the specific booking number in question, it is impossible to determine if it is invalid. Booking numbers are typically unique identifiers assigned to reservations, so if there is an issue with a booking number, it could be due to a typo, a system error, or the booking number may not exist in the system. It is recommended to double-check the booking number with the booking provider or company to verify its validity. **
