Energy and environment are co-related in the technological and scientific aspects including energy conservation, and the interaction of energy forms and systems with the physical environment. The levels of atmospheric carbon dioxide has increased by 31% between 1800 and 2000, going from 280 parts per million to 367 parts per million. Scientists predict that carbon dioxide levels could be as high as 970 parts per million by the year 2100. Different factors are responsible for this development, such as progress with respect to technical parameters of energy converters, in particular, improved efficiency; emissions characteristics and increased lifetime. Various environmental policies have been implemented across the globe for reduction of GHG emissions for improvement of environment.
