Why nuclear fusion is not possible as an energy generation initiative till now
Fusion energy, simply, is the exact oppositeof fission energy, which comes from splitting an atom and is widely used to power nuclear plants and weapons. Fusion occurs constantly on our sun, which produces most of its energy via the nuclear fusion of hydrogen into helium. When nuclei fuse, they create a heavier nucleus and produce a little leftover energy in the process. Fusion doesn't produce runaway chain reactions the way fission can, so there's no need to worry about meltdowns. Nor do fusion reactions produce the large amounts of dangerous radioactive waste that fission reactions do. That's why it's such a dreamy source of energy.
So why do we have fission power, but not fusion power? The answer is pretty simple, and very frustrating to a lot of physicists out there: For fusion to occur on Earth, you need a temperature of at least 100 million degrees Celsius—six times hotter than the core of the sun. The sun is a natural fusion reactor which makes up for its measly 15 million degrees with the intense pressure created by its core's gravity. Currently, here on Earth the amount of energy you'd need to put in to produce that kind of heat or pressure is much, much higher than what you get out in usable energy.
So due to the reasons above fusion is not possible as an energy generation initiative till now.
