FAQs on Energy from the Sun I Video Lecture - Science Olympiad Class 6

1. What is solar energy and why is it important?
Ans. Solar energy is the energy we receive from the Sun in the form of sunlight. It is important because it is a renewable source of energy, meaning it will not run out. Solar energy can be used to generate electricity, heat water, and power various devices, helping to reduce our reliance on fossil fuels and combat climate change.
2. How do solar panels work?
Ans. Solar panels work by converting sunlight into electricity. They are made up of many solar cells, which contain materials like silicon. When sunlight hits these cells, it creates an electric current through a process called the photovoltaic effect. This electricity can then be used to power homes, schools, and other buildings.
3. What are the benefits of using solar energy?
Ans. The benefits of using solar energy include reducing electricity bills, decreasing greenhouse gas emissions, and increasing energy independence. Additionally, solar energy systems require low maintenance once installed and can increase the value of a property.
4. What are some ways we can use solar energy in our daily lives?
Ans. We can use solar energy in many ways, such as installing solar panels on our rooftops for electricity, using solar water heaters for hot water, and utilizing solar-powered appliances like lights and chargers. Additionally, solar energy can be used in schools and parks to provide clean energy for lighting and other needs.
5. What is the difference between renewable and non-renewable energy?
Ans. Renewable energy comes from sources that can be replenished naturally, like solar, wind, and hydropower. Non-renewable energy, on the other hand, comes from sources that can deplete over time, such as coal, oil, and natural gas. Using renewable energy helps to ensure a sustainable environment for the future.
