Editorial Topic : Pumped Storage: A Crucial Piece in India’s Renewable Energy Puzzle

 GS-3 Mains Exam : Economy

Revision Notes

The Challenge

• India aims for 500GW non-fossil fuel energy by 2030.

• Rapid growth in renewable energy (wind and solar) is expected.

• Renewable energy is inherently variable and intermittent.

The Solution: Pumped Storage

• Stores excess energy: Pumps water to an upper reservoir when power is surplus (e.g., during sunny/windy periods).

• Generates power on demand: Releases water from the upper reservoir to generate electricity when demand is high (e.g., evening peaks).

• Balances the grid: Helps maintain a steady power supply by bridging the gap between renewable energy fluctuations and constant demand.

• Fast response: Can start/stop generation quickly, unlike coal or nuclear power plants.

India’s Current Scenario

• Relatively low pumped storage capacity compared to global leaders like China.

• Existing projects like Kadamparai demonstrate the technology’s potential.

• Potential for significant expansion given India’s geographical conditions.

The Need for Expansion

• India must significantly increase pumped storage capacity to support its renewable energy goals.

• This will enhance grid stability, reduce reliance on conventional power sources, and ensure uninterrupted power supply.

Editorial Topic : Gestational Diabetes

 GS-2 Mains Exam : Health

Revision Notes

Gestational diabetes (GDM), a type of glucose intolerance developing during pregnancy, poses significant risks to both mother and child. While traditionally diagnosed later in pregnancy, a groundbreaking shift in approach is emerging.

Early detection is key. The Delhi Declaration emphasizes screening for glucose intolerance as early as the eighth week of pregnancy. This early identification of a condition termed Early Gestational Glucose Intolerance (EGGI) allows for timely intervention. Research suggests that a 2-hour postprandial blood glucose (PPBG) level of 110 mg/dL at the tenth week of pregnancy can predict GDM.

Why is early detection so crucial? The concept of “foetal programming” underscores the impact of the prenatal environment on a child’s future health. Maternal hyperglycemia can lead to foetal hyperinsulinemia, increasing the child’s risk of obesity, insulin resistance, and type 2 diabetes later in life.

The Delhi Declaration advocates for a stringent approach to managing GDM. For women with PPBG levels above 110 mg/dL at the tenth week, medical nutrition therapy and metformin are recommended. This aggressive strategy aims to prevent the progression of GDM and its associated complications.

Ultimately, the goal is to create a generation free from diabetes. By prioritizing early screening, intervention, and strict blood glucose control, healthcare providers can significantly reduce the long-term health risks for both mother and child. This approach represents a paradigm shift in diabetes care and holds the promise of a healthier future for generations to come.

The message is clear: the health of a child begins in the womb. By addressing gestational diabetes early and effectively, we can take a substantial step towards preventing the diabetes epidemic.
