Question

In Delhi, buses and other public transport vehicles uses CNG as fuel instead of petrol or diesel; some vehicles use convertible engines; solar energy is being used to light up the streets. What do you think about these changes? Delhi also adopted odd/even scheme to restrict the use of vehicles with registration ending with odd/even numbers on alternative days, for specific period in a year. Organise a debate in class on the need for sustainable development practices in India.

Answer 1

The changes mentioned are positive steps towards sustainable development because they help reduce pollution, save non-renewable fuels and promote cleaner energy.

• Using CNG in buses and public transport reduces harmful emissions compared with petrol and diesel.
• Convertible or cleaner engines can reduce fuel consumption and air pollution.
• Solar-powered street lights save electricity and use renewable energy.
• The odd-even scheme aims to reduce the number of private vehicles on roads and thereby lower traffic congestion and air pollution.

However, such measures work best when they are supported by good public transport, proper implementation and public cooperation. These practices show how cities can move towards sustainable development by using cleaner fuels, renewable energy and measures that reduce pollution and conserve resources.
