to Congress‚ 2/24/09) Solar energy is the cleanest‚ most abundant‚ renewable energy source available which described as the sun’s rays that reach the earth and can then be converted into either thermal (heat) or electricity. Solar energy converted into heat can be used to: heat water for use in homes and buildings and heat spaces. Solar energy can be converted into electricity in two ways: 1) photovoltaic cells; and 2) solar thermal plants (also known as concentrated solar power or CSP)‚ which are

A young Venetian‚ Bassanio‚ needs a loan of three thousand ducats so that he can woo Portia‚ a wealthy Venetian heiress. He approaches his friend Antonio‚ a merchant. Antonio is short of money because all his wealth is invested in his fleet‚ which is currently at sea. He goes to a Jewish money lender‚ Shylock‚ who hates Antonio because of Antonio’s anti-semitic behaviour towards him. Shylock nevertheless agrees to make the short-term loan‚ but‚ in a moment of dark humour‚ he makes a condition - the
