What is missing in the original article and what some "I'll just leave it here (bar of consumption vs. bar of green production)" comments omit is the grid.<p>The electricity is not some component part which you order in China, stock it up in thousands in your warehouse and wait until you need it.<p>The total electricity production and consumption must be absolutely equal in ANY. GIVEN. MOMENT. If you are not generating enough, the generators would be overloaded, start slowing down and bad things would happen (frequency would lower, your own generators and/or power lines between countries will go out of phase and bang, you have a nice large several-country-wide blackout). Similar things happen when you generate too much.<p>Therefore, mentioning the current AVERAGE green production per day and consumption per day is totally out of reality, as the "base" energy is still provided by the dreaded nuclear, peak oil and very dirty coal power plants. In order to cover the consumption with the "holy" green energy, the capacity of such power plants would have to be several times the current consumption in order to generate the energy for times when there is no wind, no sunlight (night!), etc. AND many storage plants (e.g. pumped storage) have to be built. And one pumped storage plant alone (without the power plants providing the electricity into the storage!) cost the same as adding the same net power capacity in nuclear, which goes by the projections until the next scheduled shut down, no wind onsets, etc.<p>Also, please do not be fooled with the "Austrian model" - ban nuclear energy in the constitution and import (nuclear!) energy from surrounding countries. Or with the "German model" - promise to stop nuclear power plants and: a) use "green" government subsidies to start COAL power plants instead (yes, environmental funds are being used to build new power plants of the most dirty kind!), b) overload surrounding grids (Polish, Czech) to dissolve peak effects of current, very unstable, "green" sources, c) start inventing crazy things like using home water heaters running on fossil fuels (!) controlled by computers to generate electricity into the grid when the green sources are not enough...<p>Whenever anybody is speaking about noes to nuclear power or green sources, these issues should be foremost addressed. Otherwise it is the same beating around the bush, as when biofuels are governmentally subsided and made mandatory by law to be mixed into ordinary fossil fuels, but it is kept secret that the agricultural vehicles running on the fossil fuels, spreading pesticides and fertilizers made from fossil fuels, use more energy than is finally made in the "biofuel". However, this happens in some other country across the globe, so it is none of our business and it is very "green" in our "bio"fueled country...<p>Source: electrical engineer controlling the power grid of a European country.
