Terrible heat in the Summer - imagine what a one or two day power failure would do.

In the hot sun, or a very hot dwelling, the body must work to maintain its normal internal temperature, generally about ninety-eight degrees. The heart starts pumping more blood to the skin, where it can cool down. You will start sweating profusely, and might experience cramps or nausea. If you cannot find a way to cool off, your core temperature will quickly increase, forcing your heart to beat faster, which increases your metabolism, and generates more heat. As blood is diverted away from your internal organs, including your brain, they become starved of oxygen. You will feel dizzy, or faint. Once your body temperature rises above a hundred and three, heatstroke can begin. Sweating stops, and the skin will turn red, hot, and dry. Your head will throb. As the blood pressure falls in your brain, you will probably pass out. Sprawled, unconscious, in the hot sun, you will continue to overheat. Once your body reaches a hundred and five or a hundred and six degrees, your limbs might convulse, and, at a hundred and seven, your cell membranes melt, and proteins inside the cells unfold. Organ function starts to shut down; muscle tissues begin to disintegrate. It becomes increasingly difficult to cool you off fast enough to save your life. The heart just stops.

on the state of the war
A report by Yale historian Timothy Snyder

Ukraine did want to press forward last year, before the fortifications were built. It lacked the necessary weapons, and Elon Musk chose to cut Ukraine off from communications. That move likely extended the war. Because Musk’s decision was based on his internalization of Russian propaganda about nuclear war, and was accompanied by his repetition of that propaganda, he made a nuclear war more likely. If powerful men convey the message that just talking about nuclear war is enough to win conventional wars, then we will have more countries with nuclear weapons and more conventional wars that can escalate into nuclear ones. Ukraine has been resistant to this line of Russian fearmongering, fortunately for us all.
Ukraine did not have the arms it needed last year in part for the same reason: Americans allowed Russian propaganda to displace strategic calculation. By now, though, the American side has generally understood that Russia’s nuclear threat was a psychological operation meant to slow weapons deliveries. The United States and European partners have delivered arms to Ukraine, which has been absolutely indispensable. Hhistorically speaking, though, the pace is slow. Fighter planes are coming, but a year late for the current offensive. So Ukrainians are now trying an offensive in conditions that American staff officers would find challenging. Americans take for granted economic superiority, prior destruction of logistics, and air supremacy, none of which describe the Ukrainian position. Ukrainians do not even have numerical superiority, let alone of the 3-1 or 5-1 variety that would be standard advice for an offensive.
