INTRODUCTION:

More than 10 % of the global population lives in extreme poverty today; they struggle to fulfil the most basic needs like health needs, educational desires, and access to healthy water, sanitation, and clothing. Most people living on less than the minimum daily financial needs are common in rural areas. Worldwide, the poverty rate in rural areas is 17.2 %—more than three times higher than in urban areas. One child amongst five lives in extreme poverty. Ensuring social protection for all children, especially girls and other vulnerable groups, is critical to reducing poverty. It shows up as starvation and malnutrition, restricted access to healthcare and other necessities.

Introduction:

Sustainable Development Goal 7 aims to ensure affordable, reliable, sustainable, and clean energy for all. 20% of the world’s population has currently no access to modern electricity. Around 3 billion people use wood and charcoal for cooking, which leads to pollution, affects health, and generates greenhouse gases that alter the climate. The advancement in technology and changes in government policies aim to reduce the cost of renewable energy, ensuring access to clean, affordable, reliable, and sustainable energy. This in turn will promote improved health, reducing poverty, mitigate climate change’s effect, and benefit the environment.

The Goal is achieved through activities such as investing in renewable energy sources like solar power, promoting energy efficiency in buildings and industries, and expanding access to clean cooking solutions. Additionally, raising awareness and providing training on sustainable energy practices can empower communities to utilize energy resources effectively, ensuring that everyone has access to reliable and affordable energy.

Installation of BLDC (Brushless Direct Current):

DPU has replaced old traditional AC copper winding fans with new generation BLDC fans. Till Date 5200 fans are installed.

Technical details and features of BLDC fans over Winding fans are as follows.

A BLDC fan refers to a Brushless Direct Current fan, which uses a brushless DC motor to operate. These motors differ from traditional AC (Alternating Current) or brushed DC motors in several keyways.

Key Features of BLDC Fans:

1. Energy Efficiency: BLDC motors are more efficient than traditional motors because they minimize power losses. They typically save 40-70% more electricity than conventional ceiling fans.
2. No Brushes: Unlike conventional DC motors that use brushes to transfer electrical current to the rotor, BLDC motors use electronic commutation, which eliminates friction and wear, making them more durable and maintenance-free.
3. Quieter Operation: BLDC fans are quieter than traditional fans because they have fewer mechanical components that can generate noise.
4. Speed Control: These fans offer better control over speed and can be easily adjusted electronically without the humming noise that conventional fans may produce at lower speeds.
5. Long Lifespan: Since there is less friction due to the absence of brushes, BLDC motors tend to have a longer operational life.
6. Remote Control: Many BLDC fans come with smart features, including remote control or integration with smart home systems, allowing for ease of use and energy savings.

Here’s a breakdown of the comparison in terms of power consumption and efficiency:

1. Power Consumption:
   • Winding (AC Induction) Fan:
     • A typical ceiling fan with an AC induction motor consumes 70-80 watts of power at its highest speed.
   • BLDC Fan:
     • A BLDC fan consumes significantly less, usually between 25-35 watts at its highest speed.

2. Energy Savings:

• BLDC Fan:
  • On average, a BLDC fan can save 40-70% of energy compared to a traditional winding fan. For example, if a standard fan uses 75 watts, a comparable BLDC fan might only use 28 watts for the same airflow and speed.

3. Yearly Power Consumption:

Assuming an average usage of 8 hours per day for a year:

• AC Induction Fan:
  • Power Consumption = 75W × 8 hours/day × 365 days ≈ 219 kWh/year
• BLDC Fan:
  • Power Consumption = 28W × 8 hours/day × 365 days ≈ 81.8 kWh/year

3. Yearly Power Consumption:

Assuming an average usage of 8 hours per day for a year:

• AC Induction Fan:
  • Power Consumption = 75W × 8 hours/day × 365 days ≈ 219 kWh/year
• BLDC Fan:
  • Power Consumption = 28W × 8 hours/day × 365 days ≈ 81.8 kWh/year

EV charging stations supply electricity to EVs via various charging ports and methods, allowing vehicles to extend their driving range. They are a critical part of EV infrastructure, enabling the transition from internal combustion engine (ICE) vehicles to electric mobility. DPU has installed 60 KW DC CSS2 charger for charging battery Operate vehicles.

Benefits of EV Charging Stations:

1. Promoting EV Adoption:
   • The availability of charging infrastructure reduces "range anxiety" (fear of running out of battery before reaching a charging point) and encourages more people to buy EVs.
2. Environmental Benefits:
   • EVs, when powered by renewable energy at charging stations, have a significantly lower carbon footprint compared to gasoline or diesel-powered vehicles.
3. Convenience:
   • With widespread charging infrastructure, EV drivers can charge their vehicles almost anywhere, like refueling a traditional car.
