1.2.2 GENERATING ELECTRICITY 1.1 ENERGY AND LIFE 1.2.2 GENERATING ELECTRICITY (a) the advantages and disadvantages of renewable energy technologies (e.g. hydroelectric, wind power, wave power, tidal power, waste, crops, solar and wood) as a means of generating electricity on a national scale using secondary information (b) the cost effectiveness of introducing domestic solar and wind energy equipment, including fuel cost savings and payback time by using data (c) sustainability, carbon footprint, cost, reliability, environmental impact to compare different methods of power generation e.g. use data to assess their impact on the environment by considering atmospheric effects (acid rain and carbon dioxide emission), pollution including visual and noise pollution (d) the lifetime and the useful power produced by renewable energy devices and power stations e.g. solar cell, fuel cell, wind turbines and water turbines (e) the need for the National Grid as an electricity distribution system including monitoring power use and responding to changing demand (f) advantages and disadvantages of using different voltages of electricity at different points in the National Grid to include transmission of electricity and use in the home (g) the use of transformers in the transmission of electricity from the power station to the user in qualitative terms (they should be treated as voltage changers without any reference to how they perform this function) (h) efficiency, reliability, carbon footprint and output to compare different types of power stations in the UK including those fuelled by fossil fuels, nuclear fuel and renewable sources of energy SPECIFIED PRACTICAL WORK Investigation of the factors affecting the output from a solar panel
