The New Benchmark: Energy Expenditure
Considering increasing world market prices, euphonic scenarios like New Oil or New Gas
appear, giving the impression that – even on a higher cost level – the
exploitation of earlier non-economic reservoirs will be feasible. From a
technical point of view this statement may be effective, but on the long run it
is more than questionable.
Clean Coal
German edition of the Scientific American, Spektrum der Wissenschaften, published
in January 2011 an article headlined »large laundry for the climate« describing
a scenario of a clean and economically feasible technology to separate carbon
dioxide from the flue gases of coal fired power plants. The following lines –
slightly supplemented by explanations – have been published in March 2011 as
letter to the editor in reply.
Grid Stability
Fluctuating supply from wind- and photovaltic power plants is a challenge for grid operation -
a threatening collapse is not an issue.
