Nuclear Energy
Lifecycle Assessment of Electricity Generation Options. United Nations Economic Commission for Europe. The third incident that often comes to mind was the Three Mile Island accident in the US in 1979. On the seven-point International Nuclear Event Scale, this was rated as a level five event ("Accident with Wider Consequences").
Electrical generation
Electricity is an energy currency, rather than an energy source, which means that electrical generation needs to start from a primary energy source like a fuel or a primary energy flow.These fuels and flows are usually turned into electric current which transmits electric power to the grid.. Power plants are the most commonly used energy conversion …
