Rooftop greenhouses the ultimate urban peaks

Living, working and socializing in Washington D.C. causes one to consider the environment on a daily basis. Today, I had the chance to notice a few “green” spaces but also plenty of unused space. Earlier this week, I noticed many homeless requesting food. I heard on the radio that grocery chains are charging 4 times more for groceries they still produces pollution and runoff that hurt the environment and our health. In my opinion and many others these problems could be addressed using greenhouse equipment modified with renewable energy systems. Basically,  to encourage the incorporation of community greenhouses in cities with renewable energy initiatives. The concept is pretty simple, take the unwanted and unused places in the urban environment and put them to good use by building greenhouses with solar, wind, geothermal and water energy generation or conservation methods. The food that is raised from the greenhouses could go towards helping to feed the homeless in the cities and to local community markets to generate internal revenue for the local economies to help the project and the community to be self sufficient.
