Natural and Energy Resources Questions and Answers

Q: A major initiative undertaken for water conservation namely “Jalayukta Shivar” in :

Jalayukta Shivar is an initiative of Maharashtra.Jalyukt Shivar Abhiyan was launched by the Government of Maharashtra in 2014-15 to make villages drought-free. It works through watershed and water conservation measures such as deepening and widening streams, building cement nala bunds and check dams, desilting old water bodies and recharging groundwater, with the participation of villagers.Odisha, West Bengal and Rajasthan have their own water conservation schemes (Rajasthan's is the Mukhyamantri Jal Swavlamban Abhiyan), but Jalayukta Shivar is Maharashtra's.

Q: Which of the following resources is renewable ?

The renewable resource is the forest.A renewable resource is one that is replenished by natural processes within a human time scale. Forests regrow through natural regeneration and planting, so they can be used sustainably if cutting does not exceed regrowth.Coal, petroleum and natural gas are fossil fuels. They formed from buried organic matter over millions of years, and the stocks used today cannot be replaced on any useful time scale, so they are non-renewable.

Q: International Solar Alliance was established to develop co-operation in developing solar energy was proposed by :

The International Solar Alliance was proposed by the Indian Prime Minister.Prime Minister Narendra Modi proposed the alliance of solar-resource-rich countries, and he launched it jointly with French President Francois Hollande at the Paris climate conference (COP21) in November 2015. Its headquarters is in Gurugram, India.The French President was the co-founder at the launch, not the proposer, and the African Union and the European Union were not its originators.

Q: International Solar Alliance was established to promote the solar energy. Its headquarters is established at :

The headquarters of the International Solar Alliance is at Gwal Pahari, Gurgaon.The International Solar Alliance was launched by India and France at the Paris climate conference in 2015 to promote solar energy among sunshine-rich countries. Its headquarters is on the campus of the National Institute of Solar Energy at Gwal Pahari, Gurgaon (Gurugram), Haryana, making it the first international intergovernmental organisation headquartered in India.Bengaluru, Dubai and Nairobi do not host it. Nairobi is known as the headquarters of the UN Environment Programme, and the Abu Dhabi headquarters of the International Renewable Energy Agency is sometimes confused with Dubai.

Q: Which one of the natural system is used for hot water for domestic purposes ?

The system is solar-thermal.Solar water heaters use collectors that absorb sunlight as heat and transfer it to water, which is stored in an insulated tank for domestic use.Solar photovoltaic panels convert sunlight into electricity, not heat directly. Geothermal energy uses heat from inside the earth and is not a household system in most places, and a 'solar digestor' is not a standard water heating system; digesters produce biogas.Such systems are common on rooftops in India because sunlight is abundant and the heat needs no conversion into electricity.

Q: Which component of a solar panel is responsible for directly generating electric current when exposed to sunlight ?

The component is the Semiconductor material.A solar cell is made of a semiconductor, usually silicon, arranged as a p-n junction. Light absorbed in it frees electrons, and the junction's electric field drives them as a direct current: the photovoltaic effect.The inverter converts that DC into AC, reflectors only concentrate light, and batteries store the energy; none of them generates current from sunlight.

Q: International Solar Alliance headquarters is located at :

The International Solar Alliance has its headquarters in Haryana, India.The ISA was launched by India and France at the Paris climate conference (COP21) in 2015 to promote solar energy. Its headquarters is at the campus of the National Institute of Solar Energy in Gurugram (Gwal Pahari), Haryana, making it the first international intergovernmental organisation headquartered in India.Karnataka, Dubai and Colombo do not host the alliance's headquarters.

Which one of the natural system is used for hot water for domestic purposes ?

A.Solar-Thermal
B.Solar-Photovoltaic

Answer: A

The system is solar-thermal.

Solar water heaters use collectors that absorb sunlight as heat and transfer it to water, which is stored in an insulated tank for domestic use.

Solar photovoltaic panels convert sunlight into electricity, not heat directly. Geothermal energy uses heat from inside the earth and is not a household system in most places, and a 'solar digestor' is not a standard water heating system; digesters produce biogas.

Such systems are common on rooftops in India because sunlight is abundant and the heat needs no conversion into electricity.
