What do you do with grass clippings?

Is grass a renewable source of energy, like the algae below?

We collect 20-40, 50 gal. bags of grass from Verticutting a 5,000 sq. ft. lawn.  Do you collect clippings

Fellow lawn maintenance contractors, and any one who has to haul or bag grass for pick-up or dumping.  Are we missing a valuable source of income/energy? 

Grass could be the cheapest source of energy in our country. The landscape industry is one never talked about in main stream America.  The U.S. landscaping industry nets $61 billion annually, according to the Professional Landcare Network(PLANET).

In the article below they create oil from algae, I ask why not grass?  What if all that grass was collected and energy was created from it?  Right here in Pinellas Park, Fl. we burn garbage to create electric. 

Personally, I have never read or heard of any research being done with grass clippings.  If any one has, please drop us a note.

Grass may be the easiest and cheapest renewable source of energy on this earth? 

I am not advocating  we all collect clippings, yet.  We know lots of home owners do. What if the garbage collection companies had special clipping pick-up once a week. Possibly a special recyclable bag, with a simple fold-up wire basket to hold the bags for filling.

I believe this is not rocket science. 

Any ideas

Engineers at the US Department of Energy’s Pacific Northwest National Laboratory (PNNL) have created a continuous process that produces useful crude oil minutes after harvested algae is introduced. This new process does not require drying out the algae, which grows in water, saving time and energy that would be otherwise wasted. The finalproduct can be refined into aviation fuel, diesel, or gasoline.
