What are the non-renewable resources that you use daily, directly or indirectly? What are the possible renewable substitutes? What are some of the steps we can take to transition to renewables?
Non-renewable resources used daily include: petroleum (for transportation fuel and plastics), coal (for electricity generation), natural gas (for cooking and heating), and metals like iron and copper (in buildings, vehicles, and electronics).
Possible renewable substitutes include: solar energy and wind energy for electricity; biofuels or electric vehicles powered by renewable energy for transportation; biogas for cooking; and recycled or plant-based materials instead of new metals and plastics.
Steps to transition to renewables include: investing in solar panels and wind farms; using public transport or electric vehicles; reducing energy consumption through efficiency measures; recycling and reusing materials; supporting policies that promote renewable energy; and adopting the principle of judicious use of non-renewables while developing sustainable alternatives.
India's International Solar Alliance demonstrates commitment to this transition.
Explanation
The chapter discusses non-renewable resources on page 8 and the transition to renewables on pages 17-18. It mentions India's coal reserves may last only about 50 years, emphasising the need for transition. The International Solar Alliance and Bhadla Solar Park are presented as examples of India's leadership in renewable energy transition.
Solution Steps
Identify daily non-renewable resources: petroleum, coal, natural gas, and metals.
List renewable substitutes: solar energy, wind energy, biofuels, electric vehicles, and biogas.
Outline steps for transition: investing in infrastructure, using public transport, efficiency measures, recycling, and policy support.
Mention India's commitment through the International Solar Alliance.
