The city of Paris plans to expand an urban cooling system that draws on water from the Seine river as it seeks to meet rising demand for air conditioning while curbing carbon emissions, the secretary general of Paris Fraicheur Raphaelle Nayral said. - REUTERS

00:23 This is where the water from the sun is pumped in.
00:25 Here you have two identical levels which are equipped with cooling making machines.
00:29 But cool down the water circuit.
00:31 [speaking in French]
00:33 Then this is the pump sector.
00:35 Their purpose is to pump water either inside the network or within the power station.
00:39 And this is the level where we find sand water.
00:42 This is where the interface between sand water and water happens,
00:45 but has been heated during the process of creating cool.
00:49 After, the sand water goes back,
00:51 so it stays in the plant only for a few seconds before returning to a river.

01:15 If we manage to develop such a network of urban cooling instead of stand-alone air conditioning,
01:21 we could really manage to control the level of air conditioning carbon emission in Paris.
01:26 Emissions related to producing cool in the world are going to rise anyhow.
01:32 If we choose collective solutions that are resilient and efficient,
01:36 the cool balance will keep growing slightly because demand will increase.
01:40 But it will be very restrained compared to a situation where everyone has its own equipment and every man for himself.
