Energy and its resources are now the center if attention of the whole world. The demand for energy has been increasing given its obvious effect on economic growth rates, its importance in the welfare of societies and the result of the depletion of natural resources, especially fossil fuels that provide 80% of the world demand (Treiky Abd Elraouf, 2014). Meanwhile, energy sources are decreasing with an increasing rate over time, threatening as a result the world energy security and causing as well environmental pollution that has become more severe and has affected the environmental balance. For this reason its done search for alternative and renewable energy sources that are environmentally friendly, maintain environmental balance and secure energy for future generations. (Farida Kafi, 2016, p.140). The research focuses on studying the environmental and economic effect of using biological mass in producing renewable energy as an alternative to fossil fuels that would help get rid of organic wastes in an ideal way through recycling and therefore reduce pollution and consumption of fossil fuels as an energy source.     The main problem in this research is the accumulation of thousands of tons of waste all over the country and its negative impacts amidst an ongoing crisis in traditional energy sources due to increasing consumption rates. The study has reached the possibility of getting rid of huge amounts of biological wastes and converting them to valuable energy that would contribute to ending the environmental crisis, sparing the government the need to support power and reducing its imports, and the , positive effect on the national income and the cut-down of CO2 emissions. In order to achieve the objectives of the study, an applied case study was carried out on garbage residues in Menia Governorate in the Arab Republic of Egypt - comprising nine centers and seventy villages. The sample size was 300 people for 60 families (30 families characterized by urban nature and 30 families characterized by rural nature) Difference in the level of living and educational income of the families under test by collecting and sorting the solid waste generated from the houses according to the samples selected at the governorate level and the centers during 2017. The study recommends the use of biological mass, encouraging and supporting projects to convert waste to biological energy considering its role in protecting the environment. The study also recommends considering biological mass as an alternative alongside renewable sources.
