IBPS PO General Awareness: Environment & Energy questions with solutions

Q1. Passage: 20% of all energy consumed in the country is consumed for domestic household use. The country is contemplating a total ban on non-BEE 5-star rated home appliances. What can be inferred?

1. Energy consumed per person in the country would decrease significantly.
2. Home-appliance usage would not decrease significantly.
3. The energy consumed by home appliances would reduce significantly.
4. The total energy consumption of the country would reduce significantly.

Answer: Home-appliance usage would not decrease significantly.

Banning non-BEE 5-star appliances forces consumers to use more energy-efficient ones. But it doesn't restrict how much they use appliances. So energy consumed by appliances may reduce (efficient models), but home-appliance usage itself doesn't decrease. Source: Home-appliance usage would not decrease significantly.

Q2. Statement: Rooftop solar power technology is showing growth. Which is a valid assumption underlying this statement?

1. The government is providing subsidies for solar panels
2. People are becoming more environmentally conscious
3. Rooftop solar power technology is becoming more efficient
4. Electricity prices are increasing

Answer: Rooftop solar power technology is becoming more efficient

The statement says rooftop solar is growing. The most direct assumption is that the technology is improving (becoming more efficient) — this is the inherent reason for its growth. Other options (subsidies, environmental consciousness, electricity prices) are external factors, not inherent technology assumptions.
