1) How does Solar Power source work? a) Warm air above land expands and rises, and heavier, cooler air rushes in to take its place, creating wind. b) Water flows, spins a turbine, which in turn drives a generator to produce electricity. c) Solar Power works by converting energy from the sun into power. d) Solar Power work by harness natural processes to generate electricity or heat 2) Where in the world is Solar power most commonly used? Why there? a) Norway because abundant rainfall and large dams allow them to generate a significant portion of their electricity from hydropower. b) China because solar power makes more polysilicon. c) Canada because canada has a significant amount of hydro potential, with several provinces generating over 90% of their electricity through hydropower. d) Brazil because brazil relies heavily on hydropower, with the Itaipu plant on the Paraná River being one of the world's largest hydroelectric facilities in terms of electricity generation. 3) What are three benefits of using Solar Power? a) Flood control, irrigation support, and clean drinking water. b) Reducing carbon emissions and air pollution, enhancing energy security and reliability, and creating economic opportunities through job growth. c) Generating electricity, milling grains, pumping water d) Reduced electricity bills, environmental benefits like reduced carbon emissions and reliance on fossil fuels, and energy independence. 4) What are two problems or challenges with using Solar Power? a) Its intermittency, meaning it's not consistently available, and the initial cost of installation, including the cost of equipment and labor. b) Its intermittent nature and the high upfront costs associated with installation. c) It can alter aquatic habitat, flood previously dry areas, may require the expropriation of land, leading to the relocation of local communities, changes in water quality, d) Intermittency and high upfront costs. 5) How does the weather affect Solar Power? a) Influencing wind speed, air density, and turbine functionality. b) Increase output for certain renewables c) Cloudy days reduce solar power output, while calm weather diminishes wind energy generation. d) Low-elevation plants are more susceptible to weather fluctuations than high-elevation hydropower plants. 6) How does Solar Power help protect our environment? a) By provide energy for heating, cooling, and lighting homes and heating water without any direct emissions. b) Solar Power plants do not emit the waste heat and gases c) Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. d) Generating electricity without producing greenhouse gas emissions or air pollutants, 7) Is Solar Power being used in Hong Kong? If yes, where? If no, why not? a) Yes, Hong Kong is using renewable energy sources, although in a limited capacity. b) Yes, solar power is used in Hong Kong, primarily for remote weather stations and on larger installations like Hong Kong Disneyland and landfill sites, but its use is not widespread. c) Yes, hydropower is used in Hong Kong. While large-scale hydroelectric generation isn't feasible due to a lack of suitable rivers, d) Yes, Hong Kong does use wind power. Specifically, there is a commercial-scale wind turbine on Lamma Island, 8) When was Solar Energy first used in Hong Kong? a) Kowloon Tong in 1962 b) Tuen mun in 1950 c) Tai Po in 1980 d) Tsim Sha Tsui in 1978 9) When was Solar Energy first discovered? a) 1839 b) 1698 c) 1543 d) 1976 10) Who discovered Solar Energy? a) Becquerel Alexandre Edmond b) Edmond Becquerel Alexandre c) Alexandre Edmond Becquerel. d) Edmon Becque Alexandra 11) How much does Solar cost? a) HK$15 million b) HK$70,000 c) HK$100 d) HK$90,000 to HK$150,000 12) How do solar panels work? a) By converting sunlight into electricity through a process called the photovoltaic effect. b) By using the kinetic energy of the wind to spin blades, which in turn rotate a generator that produces electricity. c) Hydrogen works as an energy carrier, meaning it stores and transports energy, primarily through fuel cells. d) By harnessing naturally replenished sources like sunlight, wind, water, and earth's heat to generate power.
