In January 2009, the Green Power Partnership (GPP, sponsored by the EPA) listed Northwestern as one of the top 10 universities in the country in purchasing energy from renewable sources. The university matches 74 million kilowatt hours (kWh) of its annual energy use with Green-e Certified Renewable Energy Certificates (RECs). This green power commitment represents 30 percent of the university's total annual electricity use and places Northwestern in the EPA's Green Power Leadership Club. The 2010 Report by The Sustainable Endowments Institute awarded Northwestern a "B-" on its College Sustainability Report Card. The Initiative for Sustainability and Energy at Northwestern (ISEN), supporting research, teaching and outreach in these themes, was launched in 2008.

Who sponsored the Green Power Partnership?

Problem: Another theory describes its derivation from a non-Slavic warrior class,:42, 64–66 forming a distinct element known as the Lechici/Lekhi (Lechitów):430 :482 within the ancient Polonic tribal groupings (Indo-European caste systems). This hypothesis states this upper class was not of Slavonic extraction:482 and was of a different origin than the Slavonic peasants (kmiecie; Latin: cmethones):430 :118 over which they ruled.:482 The Szlachta were differentiated from the rural population. The nobleman's sense of distinction led to practices that in later periods would be characterized as racism.:233 The Szlachta were noble in the Aryan sense -- "noble" in contrast to the people over whom they ruled after coming into contact with them.:482 The szlachta traced their descent from Lech/Lekh, who probably founded the Polish kingdom in about the fifth century.:482 Lechia was the name of Poland in antiquity, and the szlachta's own name for themselves was Lechici/Lekhi.:482 An exact counterpart of Szlachta society was the Meerassee system of tenure of southern India—an aristocracy of equality—settled as conquerors among a separate race.:484 The Polish state paralleled the Roman Empire in that full rights of citizenship were limited to the szlachta. The szlachta were a caste, a military caste, as in Hindu society.
WHat caste system does the hindu society have?
The answer is the following: military caste


After defeating the Visigoths in only a few months, the Umayyad Caliphate started expanding rapidly in the peninsula. Beginning in 711, the land that is now Portugal became part of the vast Umayyad Caliphate's empire of Damascus, which stretched from the Indus river in the Indian sub-continent (now Pakistan) up to the South of France, until its collapse in 750. That year the west of the empire gained its independence under Abd-ar-Rahman I with the establishment of the Emirate of Córdoba. After almost two centuries, the Emirate became the Caliphate of Córdoba in 929, until its dissolution a century later in 1031 into no less than 23 small kingdoms, called Taifa kingdoms.
Under whom did the Western part of Umayyad Caliphate's empire gain its independence?
Abd-ar-Rahman
