The correct answer is: a) Biogas
Biogas is a renewable energy source that can be used to generate electricity, heat, and transportation fuel. It is produced by the anaerobic decomposition of organic matter, such as manure, sewage, and food waste. Biogas is a carbon-neutral fuel, meaning that it does not produce any net emissions of greenhouse gases.
Gujarat is promoting the use of biogas in its power sector in order to reduce its reliance on fossil fuels and to improve air quality. The state has set a target of generating 1,000 megawatts of electricity from biogas by 2022.
Biogas is a clean and efficient fuel that can help to reduce greenhouse gas emissions and improve air quality. It is a renewable resource that can be produced locally, which makes it a sustainable option for energy generation.
The other options are incorrect because:
- Nuclear power is a non-renewable energy source that produces radioactive waste.
- Natural gas is a fossil fuel that produces greenhouse gas emissions.
- Hydroelectric power is a renewable energy source, but it can have a negative impact on the environment.
I hope this helps!
