ABSTRACT
Concentrated solar power is a promising technique involving the deployment of hundreds or thousands of revolving mirrors used to focus solar energy on a column of liquid, which in turn generates steam for electric turbines. Climate change is one of several factors, including over withdrawal contributing to global water scarcity. The international energy system is in a state of constant change. Climate change's direct impacts on energy systems and resources are likely to have more negative than positive impacts on the global supply of energy. Trends in the geopolitics of energy are raising a number of concerns. Vulnerabilities in energy production, trade and distribution systems are increasingly apparent. The rise in US energy production is considerable and it has boosted energy security. Energy demand in the power sector is likely to correlate more closely with demographic change. Instability in developing nations can affect energy systems in a variety of ways as institutions become less functional.
