Sustainable Cost-Effective Solution of Climate Emergency With Many More Societal Benefits

It is very common these days to read news items like summer heat hits Asia early, killing dozens [1] or Dubai airport flooded in hours as storm dumps heaviest rain ever recorded in the desert nation of UAE etc. [2]. These data and many other such reports indicate that climate emergency is already here. According to recent report of Bloomberg New Energy Finance (BNEF) [3], the window to reach net-zero emissions by 2050 is rapidly closing. However, by taking decisive actions it is possible to get on track. Failure to take these decisive actions, even a $1.75~^{\circ }\text{C}$ global warming target will be out of reach [3]. Thus, humanity has to use the best possible technology and create new policies to avoid these catastrophic effects of climate emergency. An earlier paper [4] highlighted and explained the important role of power electronics in solving climate emergency. More recently, one of the authors briefly outlined the urgency to electrify everything and accelerate the green energy transition [5]. All current and future power systems must provide high level of resiliency and reliability. In addition, we must consider energy efficiency and cost of power systems as design criterion to achieve the goal of sustainability to mitigate the aftereffects of climate emergency. The purpose of this article is to focus on technical details and discuss policy changes required accelerating the green energy transition.
