| 1. What are the different sources of energy? |  |
Ans. The different sources of energy include fossil fuels (such as coal, oil, and natural gas), nuclear energy, renewable energy (such as solar, wind, hydroelectric, and geothermal), and biomass.
| 2. How does fossil fuel contribute to energy production? | |
Ans. Fossil fuels, such as coal, oil, and natural gas, are burned to produce heat, which is then used to generate electricity in power plants. This electricity is then distributed to homes, businesses, and industries for various purposes.
| 3. What are the advantages of renewable energy sources? | |
Ans. Renewable energy sources have several advantages. They are sustainable and do not deplete natural resources. They produce little to no greenhouse gas emissions, contributing to a cleaner environment. They also provide opportunities for energy independence and create jobs in the renewable energy sector.
| 4. How does nuclear energy work? | |
Ans. Nuclear energy is generated through a process called nuclear fission. In this process, the nucleus of an atom is split into two smaller nuclei, releasing a tremendous amount of energy in the form of heat. This heat is then used to produce steam, which drives turbines connected to generators, generating electricity.
| 5. What are the environmental impacts of different energy sources? | |
Ans. The environmental impacts of different energy sources vary. Fossil fuels contribute to air and water pollution, as well as greenhouse gas emissions, which contribute to climate change. Nuclear energy produces radioactive waste that needs to be managed carefully. Renewable energy sources have minimal environmental impacts, although some, like hydroelectric dams, can have effects on ecosystems and wildlife.
