Write an essay on the advantages and disadvantages of coal-fired power generation and nuclear energy. Using a range of different internet search engines, supported by academic references, propose at least two apparently viable alternative energy generation for New Zealand or your country of origin, and justify your views about the viability of these alternatives. Explain what you think would be the business, society, and government perspectives on each of these four energy sources: coal-fired power, nuclear energy, and the two alternatives you have identified.
