Energy: world needs and reserves

World energy demands and coal reserves

Spotreba svetovej energie a zásoby uhlia On the basis of the expected increase in the world’s population and taking the estimated improvement in both technology and living standards into account, the paper forecasts energy demands. In 2000, actual energy consumption was 380-400 EJ.year, the forecast for the year 2050 is 600-1,050 EJ.year, while for the year 2100 it is 900-3,600 EJ.year. On the ...

The Origin of Coal and World Reserves

Correction: Coral Energy Reserves and Calcification in a High-CO2 World at Two Temperatures

Rising atmospheric CO2 concentrations threaten coral reefs globally by causing ocean acidification (OA) and warming. Yet, the combined effects of elevated pCO2 and temperature on coral physiology and resilience remain poorly understood. While coral calcification and energy reserves are important health indicators, no studies to date have measured energy reserve pools (i.e., lipid, protein, and ...

World Energy Outlook : a Comparative Study

Differen world energy outlook with different horizons (2035, 2040 and 2050) show that demand for primary energy will increase. The energymix in 2050 will mainly be fossil based although the share of theses fuels will decrease. Accorging to some forecasts, energy consumption will increase more than 50 percent during next 30 years which most of this growth belongs to non-OECD countries. In supply...

Spectral Analysis of Energy-Constrained Reserves

The definition of a service is key to the ability to meter it, measure it, regulate it, price it, or otherwise take it into consideration. Reserves (a form of power supply insurance) are key to power system operability. Traditionally, reserves have been characterized in terms of time domain quantities such as ramping rate capabilities and the like. Also, traditionally such measures have not con...
