The correct answer is Option 2: Use of CNG, LPG and Gobar gas
Explanation:
- Use of conventional sources of energy (such as coal and oil) is not considered a sustainable strategy due to their environmental impact and non-renewable nature.
- Using CNG (Compressed Natural Gas), LPG (Liquefied Petroleum Gas), and Gobar gas (biogas) are more sustainable options. They are cleaner alternatives to conventional fuels and help reduce environmental pollution.
- Using fertilizers for higher yield have environmental drawbacks, such as soil degradation and water pollution, and is not always aligned with sustainable practices.
Various strategies for sustainable development are as follows:
- Use of Non-conventional Sources of Energy
- Use of LPG, Gobar Gas in rural Areas
- Use of CNG in urban Areas
- Using wind power as source of energy
- Building mini-hydel Plants
