Efficient cooling is seen as the key to keeping climate change under control

Let’s Start this Interesting Article Shared on DesiNew.xyz

ROME: After the end of the hottest decade on record, India aims to keep its homes and workplaces cool without increasing energy consumption with one simple change: increasing the temperature settings on air conditioners.
The government has mandated a default temperature of 24 ° C (75 ° F) instead of the standard 20-21C (68-70F) for units sold or sold since the beginning of this year and commercials to keep air conditioning at that level Wants buildings. .
The measure could cut national energy consumption by 24% for households and 20% for businesses, according to co-author Gabrielle Dreyfus of a report published on Friday for a switch to more energy-efficient cooling systems It is said.
The UN report states that cooling devices such as air conditioners and refrigerators are important for human health and the global economy, emissions from fossil fuels that use them may worsen climate change.
“Doubling the energy efficiency of cooling equipment could save some from 1,600 medium-sized power plants by 2030,” the report’s steering committee co-chairman Durwood Zeleke told the Thomson Reuters Foundation.
“You can avoid a tremendous amount of traditional and climate pollution,” said Zelke, head of the Institute for Governance and Sustainable Development, an American think tank.
This should be focused on in subsequent epidemic recovery plans following the report, which follows recent heatwaves in the United States and Siberia.
As climate change sometimes brings warmer days, worldwide demand for cooling devices is increasing – on top of an estimated 3.6 billion use of 10 devices every second that are currently in use.
It also said that phasing out climate-warming refrigerant gases known as hydrofluorocarbons (HFCs) could help the world avoid 0.4C global warming by 2100.
The difference is substantial in the context of the 2015 Paris Agreement on Climate Change, which aims to limit warming from pre-industrial times to 1.5C to prevent crises such as food and water scarcity, rising seas and worsening weather events.
‘Zombie’ application
The report states that improved building design can also generate employment along with the need to reduce consumption or cool down.
For example, a clean white roof that reflects 80% of sunlight remains about 30 degrees C cooler than a gray roof that reflects only 20% of sunlight and well-designed cities Which can save 25% of the energy used for heating and cooling.
Another approach is to develop national plans to meet rising cooling needs, but without corresponding increases in emissions, such as India, China, and Rwanda.
Others, such as Ghana, have banned “zombie” appliances – cheap, outdated fridges and air conditioners mostly rejected from homes in Europe and then illegally issued HFCs.
Globally, more than one billion people lack access to cooling, which puts their health and safety at risk, and further 2.2 billion are only able to afford cheaper, less energy-efficient cooling, published on Thursday A separate report states.
Dreyfus said that raising funds is very important for the sector, as many times high-cost energy efficient technologies pay for savings within just one or two years.
“These technologies exist. We just need to make policies and mechanisms accessible to people.”
