Much of the world relies on non-renewable energy to heat their homes, power their electronic devices, and power their cars. Once these energy sources are used up, they will be gone forever. Developing technologies that can efficiently use renewable energy sources is critical to our future.

Renewable resources also produce clean energy, meaning less pollution and greenhouse gas emissions, which contribute to climate change.
