FAQs on Conventional and Non conventional Sources of Energy
| 1. What are conventional sources of energy? |  |
Ans.Conventional sources of energy are those that have been used for a long time and include fossil fuels such as coal, oil, and natural gas, as well as hydroelectric power. These sources are widely utilized due to their established infrastructure and reliability in energy production. However, they are associated with environmental concerns, including greenhouse gas emissions and resource depletion.
| 2. What are non-conventional sources of energy? | |
Ans.Non-conventional sources of energy refer to renewable energy sources that are more sustainable and have lower environmental impacts. These include solar energy, wind energy, geothermal energy, biomass, and tidal energy. Non-conventional sources are gaining popularity as they help reduce dependency on fossil fuels and contribute to a cleaner environment.
| 3. How does solar energy work as a source of power? | |
Ans.Solar energy is harnessed using solar panels that contain photovoltaic cells. These cells convert sunlight into electricity through the photovoltaic effect. When sunlight hits the cells, it excites electrons, generating a flow of electricity. Solar energy can be used for residential power, heating, and even powering large-scale solar farms.
| 4. What are the advantages of using non-conventional energy sources? | |
Ans.The advantages of non-conventional energy sources include sustainability, as they are replenished naturally; reduced environmental impact, as they produce little to no greenhouse gas emissions; and energy independence, as they can be produced locally, decreasing reliance on imported fossil fuels. Additionally, they can create jobs in the emerging renewable energy sector.
| 5. What role do government policies play in promoting renewable energy? | |
Ans.Government policies play a crucial role in promoting renewable energy by providing incentives such as tax credits, subsidies, and grants for the development and installation of renewable energy technologies. Additionally, regulations and mandates can encourage the transition to cleaner energy sources, fostering innovation and investment in the renewable energy sector.
