- The newly appointed Government of a small island, depend on the import of fossil fuels to produce electricity, has the desire toinvest in one or two renewable energy technologies. The advantage of the island is the number of different renewable energypotentials. The cost of electricity on the island is $0.39 kWh.1) Using solar radiation photovoltaic technologies, it was estimated that 500 rooftops, with a total surface area of 456 000 m2 will be available to install the photovoltaic panels. Assume that the solar panels actually cover 90% of the available surface area. Given, the size of a standard photovoltaic cell is 156 mm by 156 mm and for a silicon photovoltaic cell, each PV cellproduces a current of 2.5 A at a voltage of 0.5 V. The average daily irradiance for the island is 185 W/m2. Assume the initial capacity expenditure evaluated on a yearly basis of the photovoltaic system, that covers, 90% of the available surface area is US$600 000 and the annual operating cost is US $5…Roofs are sometimes pushed off vertically during a tropical cyclone, andbuildings sometimes explode outward whenhit by a tornado.UseBernoulli’s principle to explain these phenomenaWhat is the energy source for the motion of gas in the atmosphere?
