Promoting rooftop solar installations can help:

Reduce load on the main grid
Empower consumers to generate electricity
Lower carbon footprint
All of the above

The correct answer is D. Promoting rooftop solar installations can help reduce load on the main grid, empower consumers to generate electricity, and lower carbon footprint.

  • Reduce load on the main grid. Rooftop solar panels can generate electricity directly at the point of use, which reduces the amount of electricity that needs to be transmitted from the main grid. This can help to reduce congestion on the grid and improve reliability.
  • Empower consumers to generate electricity. Rooftop solar panels give consumers the ability to generate their own electricity, which can help them to save money on their energy bills. It can also give them a sense of independence from the utility company.
  • Lower carbon footprint. Solar energy is a clean and renewable source of energy, so using rooftop solar panels can help to reduce greenhouse gas emissions and lower the carbon footprint of a home or business.

In addition to these benefits, rooftop solar installations can also create jobs, boost the local economy, and improve air quality.
