Biogas typically refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. It is a renewable energy source.
Biogas can be produced by anaerobic digestion with anaerobic bacteria, which digest material inside a closed system, or fermentation of biodegradable materials.

Energy plantation is the method in which there is the cultivation of certain species of the plants which can be used as the source of energy. They can be used as an alternative to the fossil fuels. This reduces the pressure on the fossil fuels. 

Anaerobic digestion is a natural process in which bacteria convert organic materials into biogas. It occurs in marshes and wetlands and in the digestive tract of ruminants. The bacteria are also active in landfills, where they are the principal process degrading landfilled food wastes and other 
biomass. Biogas can be collected and used as a potential energy resource. The process occurs in an anaerobic (oxygen-free) environment through the activities of acid- and methane-forming (methanogenic) bacteria that break down the organic material and produce methane and carbon dioxide in a gaseous form, known as biogas. 

The Wind is an inexhaustible source of energy. Asia's largest windmill or wind farm complex is established at Lamba village in the Jamnagar district of Gujrat. It had successfully generated 1500+ kWh in its pilot stage of 3 months. Thus the correct answer is option B.

The device which can trap the solar energy and convert the solar energy into an electrical form of energy is called as the solar cell. Solar cells are generally used for the storage of the radiations from the sun in the form of energy resource. These cells are used in the solar panels for the generation of electricity for the street lights. 

Thermal pollution is caused by change in water temperature which leads to degradation of water quality. It is caused due to use of water as a coolant by power plants and industrial manufacturers. When such water is returned to the natural environment at a higher temperature, it decreases oxygen supply and affects ecosystem composition.

Netherland is referred as the land of the windmills. There are many windmills installed in the regions called as wind farms. There are large turbines which are used for the conversion of the wind energy to produce electricity. About 3400 MW energy was produced in this region with the help of windmills.
