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…
Estimate how many large maple trees would be needed to run a dishwasher for one year. Assume the dishwasher uses 1.1 ×108Jof energy per year and a large maple tree captures 10 kg of carbon (in CO2) per year. Assume the power plant that generates the electricity is 37 %% efficient at converting the carbon in coal to electrical energy and that typical coal releases 40,000 kg of carbon (as CO2) per terajoule of energy when burned.
1) A power plant's marginal fuel cost is the rate of shift in fuel cost relative to produced power. (Is that true or false?)

- 6. Thermal energy storage is a proposed method to store solar energy in between use. This technology works by focusing solar arrays to heat up a molten salt (usually a mix of Na+/K+/Li+/NO, ). Then the energy from the molten salt can be used later to run a steam generator and produce work. a) Suppose 10,000 tons of molten salt have been heated up to 800K (1 ton 907 kg). This molten salt has a heat capacity of 1.5 J/g/K. How much heat is released from the salt when it is cooled to 550 K? b) Now suppose all of this heat is used to heat up water.
