Nuclear energy is a powerful, highly misunderstood force that might hold the key to solving global warming
- if people stop being pointlessly afraid of it.
The main lingering problem of nuclear energy is that it's associated with nuclear bombs and mysterious, deadly radiation (OH NOES!). As a consequence, it suffers from weak public support, and often faces heavy opposition. Much of this is caused by an international and quite successful anti-nuclear movement, which was one of the major driving forces behind nuclear arms reduction treaties, but has nowadays degenerated into pseudoscience and fear-mongering.
