Question

What are non-conventional energy resources? Explain any two.

Hint:

Non-conventional energy is the future—solar and wind are not just renewable; they are key to achieving a sustainable, clean, and energy-efficient world.

Answer 1

Introduction to Non-Conventional Energy Resources:
Non-conventional energy resources are those that are considered alternative to conventional fossil fuels like coal, oil, and natural gas. These resources are typically renewable, eco-friendly, and have less environmental impact. Non-conventional energy is essential in the global effort to reduce pollution, mitigate climate change, and ensure sustainable energy use for the future.
Types of Non-Conventional Energy Resources:
1. Solar Energy:
- Solar energy is derived from the Sun's radiation. It is one of the most abundant and renewable energy resources. Solar panels convert sunlight into electricity or heat.
- Uses: Solar energy is used for generating electricity, heating water, and even powering small devices like calculators and lights. Solar farms provide a large-scale alternative to fossil fuels.
- Advantages: It is free, abundant, and produces no pollution. It is a long-term solution for energy needs and reduces dependency on non-renewable resources.
- Challenges: Solar energy depends on weather conditions, and energy storage systems for solar power can be costly.
2. Wind Energy:
- Wind energy is captured using wind turbines that convert the kinetic energy of wind into mechanical power or electricity. It is considered one of the fastest-growing renewable energy sources.
- Uses: Wind turbines are used to generate electricity, especially in coastal and hilly areas with high wind speeds. Offshore wind farms are becoming increasingly popular as they capture stronger and more consistent winds.
- Advantages: Wind energy is clean, renewable, and abundant. It can be harnessed without depleting natural resources.
- Challenges: Wind turbines are not suitable for every region, as they require areas with high and consistent wind speeds. There are also concerns about the impact on local wildlife and the aesthetic impact of turbines.
Conclusion:
Non-conventional energy resources like solar and wind energy are essential to meet the growing global demand for energy while addressing environmental concerns. These resources provide a sustainable and renewable alternative to conventional fossil fuels, reducing pollution and enhancing energy security for the future.
