Anti-greenhouse effect in white

US Energy Secretary Steven Chu yesterday announced that the Obama administration wanted to paint white roofs, roads and sidewalks to reduce the pace of climate change.

The announcement of Mr. Zhou, the Nobel Prize winner, was made when he attended a climate change symposium in London. He also called on countries to conduct a "new revolution" in the energy sector to cut greenhouse gas emissions.

The US Energy Secretary warned that humanity has not been able to find a truly effective way to combat climate change. He said that countries should adopt many solutions, including the spread of white paint on rooftops and roads. According to him, this is the 'absolute friendly' solution to the environment. It can help buildings become cooler, reduce the amount of electricity the air conditioner uses and cause sunlight to reflect back into space.

According to a study by Lawrence Berkeley National Laboratory Center (USA), if white replaces dark colors on rooftops, sidewalks, roads of the 100 largest cities in the world, greenhouse gases can reduce to 44 billion tons. The reason why white reduces the warming of the climate is simple: white reflects the sun more than black and dark colors. A white roof of 10 square meters can reduce 1 ton of CO ₂ . In countries with hot and humid climates, white roofs also help reduce up to 20% of air-conditioning costs in hot months.

Many people experience eye pain when they see white. Zhou said that the scientists have made white paints with subdued tones, but still have the ability to 'flip' sunlight like ordinary white paint. He confirmed that air conditioners in cars painted in white or light colors always consume less power than those in dark colors.

Speaking at a symposium on climate change - where more than 20 Nobel laureates - the energy minister - said that governments need to pursue a whole new mindset in their efforts. cut carbon emissions caused by energy production.

'The industrial revolution is essentially a revolution in energy use. In the beginning, humanity only used human power and animal power, then we entered the period of fossil fuel use. Now we need to conduct a new revolution to reduce carbon emissions in the energy production process , 'he said.
