I have a noble idea in the field of renewable energy, and you can design a

* Small hydro-mechanical design

* Solar powered device that produced electricity
* Small windmill that generates power  

You have other lots of options, and you can design  

* An industry emitting polluted black water. You can add black dye in a pot inside the factory area to resemble the near water.

* A chimney emitting the high amount of dark, dusty air. You can produce bad air inside the chimney by lighting an aggarbatti.
