How to save money with your AC<\/p>\n
According to the U.S. Department of Energy, adjusting your thermostat by 4 to 6 C for eight hours a day can save up to 10 per cent a year on heating and cooling.<\/p>\n
Experts say there are a lot of factors to consider when deciding what AC habits save the most energy and money.<\/p>\n
\u201cIf you\u2019re gone for like 15 minutes to go to the grocery store, you don\u2019t get any gain\u201d by turning off your AC, said Elizabeth Hewitt, professor and urban planning expert at Stony Brook University in New York state.<\/p>\n
But as a general rule, \u201cif you\u2019re going for your work day, say for eight hours or so, you\u2019ll almost always save more energy and money by turning things off,\u201d she said.<\/p>\n

In extreme conditions, a fan may provide little benefit and can even contribute to heat gain.<\/p>\n \u201cTo understand the problem, you need to start thinking that people are like a little heater,\u201d said Stefano Schiavon, a professor of architecture and civil and environmental engineering at the University of California, Berkeley, in an interview with CTVNews.ca.<\/p>\n \u201cThere is heat that we generate inside the body and that heat needs to be constantly released.\u201d<\/p>\n Under normal conditions, the body loses heat to the surrounding air when the air is cooler than the skin. This process is known as convection – heat moving from the body into cooler air.<\/p>\n At a certain point, however, that airflow can become counterproductive, because the body can begin absorbing heat from the environment instead.<\/p>\n \u201cWhen the temperature is above the temperature of your skin, then the first mechanism, convection, doesn\u2019t work anymore,\u201d Schiavon said. \u201cIt actually harms you because it\u2019s warming you up.\u201d<\/p>\n In more humid conditions, fans can continue to help by improving evaporation when sweat is not evaporating efficiently on its own. But as humidity rises further, evaporation becomes increasingly difficult and the cooling benefits of a fan may diminish.<\/p>\n Tammy Ibrahimpoor<\/a>, CTVNews.ca producer.

Read the full story here<\/a>.<\/p>\n Deaths surged by nearly a third in France during the hottest week of a record heat wave last month, the country\u2019s public health authority said Friday, reporting at least 2,000 more deaths than in the previous week when temperatures were already climbing and filling emergency wards with heat victims.<\/p>\n The new and still incomplete figures from Public Health France doubled its first preliminary estimate of at least 1,000 additional deaths that it gave last Sunday. That earlier estimate covered just three of the hottest days of extreme, deadly heat.<\/p>\n In Paris, funeral service directors have said they\u2019ve struggled to find places to store bodies before burial or cremation, with some mortuaries saying they were full and having to turn bodies away.<\/p>\n The updated tally of deaths from Public Health France spans the week of June 22-28, during which France saw its hottest-ever days and records shattered for peak daytime and nighttime temperatures in many cities and towns across the country. The heat also broke temperature records in many other parts of Europe.<\/p>\n![\"\"](\"https:\/\/www.newsbeep.com\/ca\/wp-content\/uploads\/2026\/07\/G6SJ45WWQFGN3BMA4R2GUHWXPM.jpg\")
