Energy is one the pillars, on which our modern society rests.
In classical mathematics defined as the potential to do work, it has become an indispensable good.
The continuous and sufficient energy-supply ensures clean drinking-water, mobility and illuminates the nights.
Our progressive life-style requires staggering amounts of this precious good and the demand constantly increases.
In this video I want to talk about the status-qou
present some facts and numbers and future development.
Energy is measured in Joule.
One Joule is the energy needed to lift a mass of about 0,102 kg one meter.
In 2008 the worlds energy-consumption amounted to 472,89 exajoules.
That is equivalent to the energy-contents of 11,29 gigatons oil.
If the trend from 2000 to 2008 continues.
the amount of energy needed in 2015 will be 560 exajoules.
Main energy sources are oil with 35%, natural gas with 24%,
coal with 29%, nuclear energy with 5,5% and hydro-power with 6%.
The remaining 0,5% account for solar, wind and other alternative energy-sources.
The trends continuation shows a distinct growth of fossil fuels,
which will probably bring some environmentalists to the scene.
Being presented with such Numbers has become daily routine.
like ceremonial relativization and dooms-day-scenarios.
One could argue about the Numbers or demand the return to an agrarian society,
but it would not change the fact: our demand for energy will increase.
This only leaves one question:
What energy-sources can we exploit to cover our future-demand
and how big an environmental damage are we prepared to accept?
The run-away green-house-effect accompanied by storms and droughts;
Should this be the future weather-forecast?
Wars for nearly dry oil-sources,
the impending environmental damage, that could result from offshore-drilling,
and the extraction from oil-sand;
Is this the fuel of progress?
The dead land left by burning coal-beds;
Does this feed the worlds hunger?
I do not want to call for pessimism but intend to provoke some thoughts.
In coming videos I will focus on potentials and problems.
and would also like to discuss you ideas. �
