Sweltering temperatures have hit the globe during the last couple of months. In India, some areas reached 50.8° C. In the Middle East, a high of 54° C scorched Kuwait. In the US, several major cities reported temperatures of 38°C and in Europe, Paris reached an all time high of 42.6 °C. And the list goes on, across Africa, Australia… At 900 km from the North Pole, in Canada, 21 °C was recorded. If anything, these high temperatures, which have provoked severe water shortages in India, for instance, have made people acutely aware that this might be the new normal.
According to many scientists, heat waves on a global scale could become more frequent and intense in coming decades. While some of them deny that this hot weather is related to global warming, most see it as an indication of what is to be expected in the future and a direct result of the warming up of our planet. There are a number of immediate measures that can help to mitigate the effects of these high temperatures (planting more trees in urban centres, painting roads white, etc…). In the longer run, however, the switch to using “clean” electricity – i.e. generated by renewable forms of energy – is viewed as one of the main ways of reducing Co2 emissions, and thereby reducing global warming.
Increased energy efficiency is also a way to diminish our global footprint. This can be achieved by all of us on an individual level, but also by the electricity industry and electrical and electronic device manufacturers.
IEC has published numerous standards which pave the way for the use of renewable energies. Several technical committees work on establishing standards for solar modules, wind energy systems, hydraulic turbines, solar thermal installations, wave and tidal converters, etc…
Efficient electrical energy transmission is also encouraged by many IEC Standards. To give just one example, IEC TC 20 recently published IEC 63075 which establishes test methods and requirements for superconducting AC power cables and their accessories. These cables are much more energy efficient than conventional ones.
