Future Energy
The electricity requirements of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. It is also now widely recognized that the fossil fuels (i.e., coal, petroleum and natural gas) and other conventional resources, presently being used for generation of electrical energy, may not be either sufficient or suitable to keep pace with ever i...
متن کاملEnergy Resources in the Future
Recent statistics indicate that in 2005 the world consumed about 0.5 ZJ (ZJ = 10 Joules) of energy. If one assumes that the future world population stabilizes at 10 billions, and the people consume a similar amount of energy per capita to that of the people in the presently developed countries, the world will need about 2 ZJ a year. A recent survey of the available future energy resources indic...
متن کاملPlanning for future energy resources.
WE AGREE WITH M. I. HOFFERT ET AL. (“Advanced technology paths to global climate stability: energy for a greenhouse planet,” Review, 1 Nov., p. 981) that stabilizing atmospheric CO2 concentrations at 550 parts per million (ppm) or below will require investment in energy research and development well in excess of current levels. However, their conclusion—that known technological options are not ...
متن کاملDark Energy Present and Future
By studying the present cosmological data, particularly on CMB, SNeIA and LSS, we find that the future fate of the universe, for simple linear models of the dark energy equation-ofstate, can vary between the extremes of (I) a divergence of the scale factor in as little as 7 Gyr; (II) an infinite lifetime of the universe with dark energy dominant for all future time; (III) a disappearing dark en...
