. (B) Read the following passage and write its summary: Suggest a suitable title, Turbine lo padure electricit stanowill then und The Latin word for sun is "Solar" and thus solar energy is a powerful source of energy coming from the sun. For billions of years, the sun has produced energy. It is estimated that the sunlight that shines on the Earth for one hour is capable of meeting the energy demands of the whole world for an entire year! Can you imagine that? Solar energy can be converted into other forms of energy, most commonly heat and electricity John Herschel, a British astronomer in the 1830s, used a solar collector box to cook his food while on an African expedition exploring differing terrain. Today, people use solar energy as an integral part of their lives and for all sorts of things ranging from heating water in homes to space heating in buildings, Bon from drying farm products to generating electrical energy and even heating their swimming pools! Photovoltaic is the process of using solar energy directly to make electricity using specific devices. Electricity can also be produced indirectly from steam generators which use solar thermal collectors ir heating a working fluid. How does solar energy actually work? The sun's light is harnessed by passive solar systems for heating or cooling buildings, flat plate solar collectors, and solar concentrator powe systems. The sun's heat is used to create steam, which then turns a turbine to produce electricit The drawbacks of solar energy are the large area required for collection and the manner in which comes to the surface of the earth. the earth
