As a result of accelerated development and implementation in the past few years, renewable energy has emerged from niche markets to become a mainstream player in the energy market. Renewable energy technologies are based on energy sources that are practically inexhaustible because most are solar derivatives. Although renewable energy currently represents a small fraction of overall energy supply, its use is growing rapidly due to a combination of environmental and political drivers. Renewable energy technologies are often favored by the public over conventional fossil fuel technologies because of the perception that renewable technologies are more environmentally benign and sustainable. The international community has embraced this opinion in recent years as there has been growing concern about the potential effects of greenhouse gas emissions and global warming. From the current amount of waste in Mashhad city, a total of 153208586 KW of energy can be potentially harnessed in the year of 2010.
