Edge computing can reduce overall energy consumption by processing data closer to source.
- True
- False
Answer: True
Edge computing reduces data transmission to cloud, lowering network energy use. Local processing enables real-time decisions with lower latency. Trade-off: managing distributed infrastructure complexity.
The technology that converts CO2 into useful products like fuels or chemicals is called Carbon ________.
- Vector
- Utilization / CCU
- Stratified
- Digital / e₹
Answer: Utilization / CCU
CCU (Carbon Capture and Utilization) transforms captured CO2 into products: synthetic fuels, plastics, concrete, chemicals. Creates economic value while reducing emissions. India researching CCU pathways under climate innovation.
Which data center cooling technology uses outside air to reduce mechanical cooling needs?
- Chilled Water
- Free Air Cooling
- Liquid Immersion
- Evaporative Cooling
Answer: Free Air Cooling
Free air cooling uses filtered outside air when ambient conditions permit, reducing chiller usage by 30-70%. Implemented in Google, Facebook data centers. Critical for PUE improvement and operational cost reduction.
Article 6.4 of Paris Agreement establishes a centralized mechanism for international carbon trading.
- True
- False
Answer: True
Article 6.4 creates UN-supervised mechanism for trading emission reductions between countries, replacing CDM. Aims to ensure environmental integrity, avoid double counting, and support sustainable development.
Which renewable energy technology has seen fastest cost decline globally in past decade?
- Solar PV
- Wind Power
- Hydropower
- Geothermal
Answer: Solar PV
Solar PV costs declined ~90% (2010-2020) due to manufacturing scale, technology improvements, and supply chain optimization. Now cheapest electricity source in many regions. India targets 500 GW renewable capacity by 2030.
The practice of designing software to minimize energy consumption is called ________ Programming.
- Green / Energy-Efficient
- Two-Tier / Hybrid
- Patch
- Augmented
Answer: Green / Energy-Efficient
Green programming optimizes algorithms, data structures, and code execution for lower CPU/memory usage, reducing energy footprint. Critical for sustainable software development and large-scale systems.
Carbon credits represent one tonne of CO2 equivalent emission reduction or removal.
- True
- False
Answer: True
One carbon credit = 1 tonne CO2e reduced/removed. Traded in compliance markets (regulated caps) and voluntary markets (corporate ESG). Quality depends on additionality, permanence, and verification standards.
Which technology captures CO2 directly from ambient air for storage or utilization?
- Point Source CCS
- Direct Air Capture
- Bioenergy CCS
- Enhanced Weathering
Answer: Direct Air Capture
DAC uses chemical sorbents to extract CO2 from ambient air, enabling carbon removal independent of emission sources. Energy-intensive but critical for net-zero pathways. India exploring DAC under climate strategy.
The process of using lunar resources for construction and manufacturing is called In-________ Resource Utilization.
- Transaction / AML
- Situ / ISRU
- Carbon / Emissions
- Responsible
Answer: Situ / ISRU
ISRU extracts and processes lunar materials (regolith, water ice) for construction, life support, and propellant production. Critical for sustainable lunar bases and deep space exploration economics.
Which technology enables high-throughput satellites to serve multiple beams simultaneously?
- Frequency Reuse
- Spot Beams
- Adaptive Coding
- All of these
Answer: All of these
HTS combines: spot beams for focused coverage, frequency reuse for capacity multiplication, adaptive coding for link optimization. Enables 100+ Gbps throughput for broadband, backhaul, and enterprise services.
Cubesats are standardized small satellites measuring 10x10x10 cm per unit.
- True
- False
Answer: True
Cubesat standard (1U = 10x10x10 cm, up to 12U) enables low-cost access to space for research, technology demos, and education. India promotes Cubesats via ISRO and academic programs for capacity building.
Which lunar resource is valuable for nuclear fusion research?
- Water Ice
- Helium-3
- Rare Earth Elements
- Titanium
Answer: Helium-3
Helium-3, deposited by solar wind on lunar surface, is a potential fuel for aneutronic fusion reactors producing minimal radioactive waste. Extraction remains technologically challenging but scientifically valuable.
The technique of dynamically allocating bandwidth based on demand in satellite networks is called ________ Access.
- Gate-All-Around / GAA
- Demand Assigned Multiple / DAMA
