Wind Energy can Raise Emission Levels

It looks like the World energy Council knows what we already know. How come the govt. seems to be in the dark

*_Technical and Environmental Considerations_*
The bulk of electric power cannot currently be stored in an economically feasible way. It has to be generated at the same time it is used, and electricity grids require power to be supplied
at the rated frequency and voltage, free from harmonics, voltage surges and interruptions. A modern industrialized society depends heavily on stable and high quality power supplies to
run industrial processes and information technology. There are, therefore, a number of operational aspects which have to be taken into account when specific energy targets are considered. For the deployment of renewables on a large scale, these include the intermittent nature of leading sources, the related problems of full integration with grids, low capacity factors and the need for back-up power.
*When renewable energy targets are aimed at the reduction of GHG emissions*, broad technical issues should be taken into consideration. For example, emissions per kilowatt-hour from
conventional power stations are reduced by maximizing their base-load operation; however, integration of some renewable generating capacities into the grid can increase frequency
fluctuations, thus raising the overall emissions levels. Another issue, which in many cases is not fully taken into account, is back-up capacity to provide electricity at short notice, which
most often relies on diesel or coal-fired generating units.
