All of the above

The correct answer is: All of the above.

Energy efficiency measures in industries and households can help Tamil Nadu in the following ways:

  • Reduce energy consumption: By using energy more efficiently, industries and households can reduce the amount of energy they use. This can lead to lower energy bills and a reduction in greenhouse gas emissions.
  • Manage peak demand: When demand for energy is high, such as during peak hours, the cost of energy can increase. Energy efficiency measures can help to reduce peak demand, which can lead to lower energy costs for everyone.
  • Lower carbon emissions: When we use energy less efficiently, we produce more greenhouse gas emissions. Energy efficiency measures can help to reduce greenhouse gas emissions, which can help to mitigate climate change.

In addition to the above, energy efficiency measures can also help to improve air quality, create jobs, and boost economic growth.
