Match List I with List II

Choose the correct answer from the options given below:

A-II, B-IV, C-III, D-I

Solar power: India is naturally endowed with a large quantity of solar energy in the form of sunlight. Plants use solar energy to perform photosynthesis. Now, with the help of photovoltaic cells, solar energy can be converted into electricity. These cells use special kind of materials to capture solar energy and then convert the energy into electricity. This technology is extremely useful for remote areas and for places where supply of power through grid or power lines is either not possible or proves very costly.

Gobar gas: Households in rural areas generally use wood, dung cake or other biomass as fuel. This practice has several adverse implications like deforestation, reduction in green cover, wastage of cattle dung and air pollution. To rectify the situation, subsidized LPG is being provided. In addition, gobar gas plants are being provided through easy loans and subsidy. 

Biopest control: With the advent of green revolution, the entire country entered into a frenzy to use more and more chemical pesticides for higher yield. Soon, the adverse impacts began to show. To meet this challenge, efforts are on to bring in better methods of pest control. One such step is the use of pesticides based on plant products. Neem trees are proving to be quite useful.

Biocomposting: In our quest to increase agricultural production during the last five decades or so, we almost totally neglected the use of compost and completely switched over to chemical fertilisers. The result is that large tracts of productive land have been adversely affected. Farmers, in large numbers all over the country, have started using compost made from organic wastes of different types. Earthworms can convert organic matter into compost faster than the normal composting process.
