How can I decrease my gas spending with my Toyota Prius?

I have noticed that my gas spending has been increasing since I bought my Toyota Prius. Is there anything I can do to decrease it?

You can also try adjusting your driving habits to be more conservative. Avoid rapid acceleration and braking, as well as unnecessary idling. This will also help improve your fuel efficiency and decrease gas spending.

Investing in a hybrid solar system for your Toyota Prius can also greatly decrease your gas spending. With this system, you can charge your car's battery using solar power instead of relying on gas.
