विविध ऊर्जा स्त्रोतांबाबत पुढील विधाने पहावीत :
(a) तेल : बाहेर पडल्यावर प्राणवायू कमी करते.
(b) वायू : नवीन स्त्रोत शोधणे सोपे नाही.
(c) जळाऊ लाकूड : संकलन वेळ खाऊ
(d) कोळसा : वाहतुकीस अवघड
(e) धरणे : स्थांनिकांचे स्थलांतर/विस्थापन
(f) सूर्य ऊर्जा : रेडिओ व दूरदर्शन प्रसारणास अडचण
(g) लाटा : वन्यप्राणी निवासास धोका
(h) बायोगॅस : हरितगृह परिणाम
(i) वारे : विखुरलेले स्त्रोत म्हणून वाया जाते.
(j) भूऔष्णिक : दूरस्थित म्हणून वाहतुकीस महाग
वरीलपैकी कोणती विधाने चुकीची आहेत ?

The correct answer is Option C ((f) and (i)).

Key Points:
• Core Concept
• Renewable and conventional energy sources have specific environmental, operational, and physical limitations.
• Why Correct
• The question asks which statements are NOT correct:
• Statement (f) claims Solar energy "disturbs radio and TV reception." This is false; solar photovoltaic panels produce direct current electricity silently without transmitting electromagnetic interference that disrupts radio or TV broadcast frequencies (it is actually wind turbines that can cause radar/broadcast interference).
• Statement (i) claims Wind energy "diffused source so gets wasted." While wind is diffused and site-specific, it is not inherently 'wasted' as unharnessable trash; rather, its limitation is intermittency, noise, and visual pollution.
• Hence, (f) and (i) are scientifically incorrect statements, making Option 3 correct.
• Key Details
• Oil spills deplete marine oxygen (hypoxia), biogas utilizes greenhouse gases rather than causing them if controlled, and dams displace communities.
• Exam Traps
• Radio interference is typically attributed to massive rotating wind turbine blades, not solar energy.
• Other Options
• Statements (a), (b), (c), (d), (e), and (g) describe genuine real-world impacts.
• Key Takeaway: Solar energy does not cause broadcast interference, and wind power is harnessable, making statements (f) and (i) incorrect.
