Clean Energy - GS questions based on daily current affairs

1)   Which of the following statement/s is/are correct regarding OTEC?

1) Ocean Thermal Energy conversion uses water as a working fluid for energy transfer.
2) A prototype experimental plant is working in Tamil Nadu in India.

a. Only 1
b. Only 2
c. Both 1 and 2
d. None of the above
Answer  Explanation 

ANSWER: None of the above

Explanation:
Ocean thermal energy conversion (OTEC) uses the temperature difference between cooler deep and warmer shallow or surface seawaters to run a heat engine and produce useful work, usually in the form of electricity. However, since the temperature differential is small, the efficiency is low, decreasing the economic feasibility of ocean thermal energy for electricity generation. It needs a working fluid with low boiling point and hence refrigerants like ammonia or R-134a are used. In some cases vapor given out by seawater itself is used. Currently the world’s only operating OTEC plant is in Japan, overseen by Saga University. In 2002, India tested a 1 MW floating OTEC pilot plant near Tamil Nadu. The plant was ultimately unsuccessful due to a failure of the deep sea cold water pipe.
2)   Which of the following statement / s is / are correct?

1) LPG consists mostly of methane.
2) CNG is suitable for cars and heavy vehicles like buses and LNG is suitable for light vehicles like two and three wheelers.

a. Only 1
b. Only 2
c. Both 1 and 2
d. None of the above
Answer  Explanation 

ANSWER: None of the above

Explanation:
LPG has mostly propane and butane. LNG has mostly methane. LPG is suitable for large and heavy diesel vehicles like trucks and buses. LPG, LNG and CNG are cleaner than petrol and diesel.
3)   Which of the following statement / s is / are correct?

1) National Clean Energy Fund was constituted in the Consolidated Fund of India.
2) The Clean Energy Cess levied on certain goods funds this Fund.

a. Only 1
b. Only 2
c. Both 1 and 2
d. None of the above
Answer  Explanation 

ANSWER: Only 2

Explanation:
It was constituted in the Public Account of India. National Clean Energy Fund (NCEF) is created for funding research and innovative projects in clean energy technologies.
