2. G7 calls for faster fossil fuel phase-out, but sets no deadline. 

The Group of Seven (G7) nations have called for a faster phase-out of fossil fuels, but they have not set a deadline. The G7 leaders met in Germany this week and agreed to work towards a clean energy transition.

3. New battery storage capacity to grow over 400GWh annually by 2030.

The global battery storage market is expected to grow rapidly in the coming years. The International Energy Agency (IEA) predicts that new battery storage capacity will grow by over 400GWh annually by 2030. This growth will be driven by the increasing use of renewable energy and the need for grid flexibility.

3.Renewables capacity to reach 4,500GW in 2024.

The IEA also predicts that the global installed capacity of renewable energy will reach 4,500GW by 2024. This would represent a significant increase from the current level of 2,500GW. The growth of renewable energy will be driven by the falling cost of solar and wind power.

In addition to these news items, there are a number of other important power and energy projects underway in Asia. 

These include: 

a. The Australia-Asia PowerLink, which will connect Australia to Singapore via a submarine power cable.

Rawlplug

Rawlplug was invented by John Joseph Rawlings, who founded the Rawlplug Company in 1919.

Rawlings was a carpenter who had a vision for a better way to fasten wood to walls. He developed a new type of anchor that used a tapered plug made of a special material that could expand when a screw was inserted, providing a secure and reliable fixing. Rawlings named the product the Rawlplug, and it quickly became popular with builders and tradespeople in the UK and beyond. Today, Rawlplug is a global brand that produces a wide range of fasteners and fixings for construction and industrial applications.

Dust effect on temperature and productivity of solar panels in desert area

Dust accumulation on solar panels can have a significant impact on their performance, especially in desert areas where dust storms are common. The accumulation of dust on solar panels can reduce the amount of sunlight that reaches the solar cells, which in turn can reduce the efficiency of the solar panel in converting sunlight into electricity. This reduction in efficiency can lead to a decrease in the output of the solar panel, which can have a negative impact on the productivity of solar power plants.

Dust accumulation on solar panels can also affect the temperature of the panels. When dust accumulates on the surface of the solar panel, it can act as an insulator, trapping heat and increasing the temperature of the panel. This increase in temperature can reduce the efficiency of the solar panel and lead to a decrease in the output of the solar panel.

To maintain the productivity of solar panels in desert areas, it is important to regularly clean the panels to remove dust and other debris that may accumulate on the surface. This can be done manually or through automated cleaning systems that use water and brushes to remove the dust. Additionally, some solar panels are designed with anti-reflective coatings or self-cleaning technologies that help to reduce the accumulation of dust and maintain the efficiency of the solar panel.

Chandrayaan-3

Chandrayaan-3 is the third lunar exploration mission by the Indian Space Research Organisation (ISRO). It is a follow-on mission to Chandrayaan-2, which was launched in 2019. Chandrayaan-3 consists of a lander and the Pragyan rover, similar to Chandrayaan-2, but does not have an orbiter. Its propulsion module behaves like a communication relay satellite.

The Chandrayaan-3 mission was launched on July 14, 2023, from Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, India. The spacecraft was successfully placed in a 100 km circular polar orbit around the moon. The lander and rover are expected to land near the lunar south pole region on August 23, 2023.

The main objectives of the Chandrayaan-3 mission are to:

• Demonstrate end-to-end landing and roving capabilities on the lunar surface.
• Study the lunar south pole region, which is thought to be rich in water ice.
• Conduct a variety of scientific experiments to understand the moon's geology, composition, and environment.

The Chandrayaan-3 mission is a significant milestone in India's space program. It is the first time that India will attempt to land a spacecraft on the lunar south pole region. The success of this mission will pave the way for future lunar exploration missions by India.

Some key differences between Chandrayaan-2 and Chandrayaan-3:

• Chandrayaan-3 does not have an orbiter.
• The Chandrayaan-3 lander has solar panels on four sides, instead of only two in Chandrayaan-2.
• The Chandrayaan-3 rover is smaller and lighter than the Chandrayaan-2 rover.
• The Chandrayaan-3 mission is expected to last for one year, while the Chandrayaan-2 mission lasted for about two years.

Electrical safety tips for home

Here are five tips for electrical safety:

1. Never touch electrical appliances or outlets with wet hands or while standing in water. Water is a conductor of electricity and can cause electric shock, which can be fatal.

2. Use only properly grounded electrical outlets, and never overload them with too many appliances. Overloaded outlets can cause electrical fires.

3. Always use electrical cords that are in good condition and properly rated for their intended use. Damaged cords can cause electric shock or fires.

4. Keep flammable materials away from electrical appliances and outlets. Flammable materials such as curtains or paper can catch fire if they come into contact with heat generated by electrical appliances.

5. Never attempt to repair electrical appliances or outlets yourself unless you are a trained electrician. Improper repairs can cause electric shock or fires, and may also void the manufacturer's warranty.

Connecting North to South of Afghanistan

Taliban government inaugurated the construction of Salang pass high.

The Salang Pass is a high mountain pass in Afghanistan that connects the capital city of Kabul with the northern provinces. The Salang Pass highway, also known as the Salang Tunnel road, is the main road that goes through the pass, and it is considered to be one of the most important highways in Afghanistan. The road was built by the Soviet Union in the 1960s and 1970s, and it has since undergone significant repairs and upgrades.

The Salang Pass highway is approximately 86 kilometers long and reaches an elevation of 3,400 meters above sea level at the Salang Pass. The road is known for its challenging conditions, particularly during the winter months when heavy snowfall can make driving treacherous. The Salang Tunnel, which is the longest tunnel in Afghanistan, runs through the center of the pass and is an important transportation link between northern and southern Afghanistan.

Despite its importance, the Salang Pass highway has been the site of several deadly accidents and avalanches over the years, including a major avalanche in 2010 that killed at least 170 people.
