Germany’s recyclable energy overdose

Germany currently produces over 35 percent of its annual electricity usage from solar and wind sources. More than 30,000 turbines of wind have been made, with an entirely installed capacity of about 60 GW. Germany currently has an equivalent of 1.7 million solar energy installations, having an installed capacity of 46 GW. This appears very inspiring.

Unluckily, most of the time, the definite electricity amount produced is about a fraction of the capacity installed. Worse on not so good days, it could fall to almost zero. In the year 2016, for instance, the wind did not blow in the county for about 52 nights. There was no wind, no sun, even taking the h better days into account. The low wind electricity output and solar power installation in Germany add up to only around 17 percent of the capacity installed.

The apparent lesson is: if you need a steady, secure supply of electricity, then you will require reserve or backup electricity sources that could be activated on additional or less short notice to filling the gaps between the demand of electricity and the changeable output from solar and wind sources.

The moiré solar and wind power a country decides to produce, the more capacity of backup it will need, on bad days, the sources of backup should be in a position to offer up to 100 percent of the country’s demand of electricity. On the good days, the sources of back up will be needed less, or at some point, turned off to reduce their utilization capacity. 

Much enhanced would be to reduce solar and wind to a comparative minimum and depend upon controllable and power sources that do not fluctuate working with a towering capacity factor, to accomplish the country’s baseload requirements of electricity and to change the sum output according to the varying demand. This corresponds to the global practice previously to the new big building with the recyclable power. 

In hypothesis, the perfect backup for solar and wind energy would be to keep extra electricity produced during the sunshine and when vigorous winds are blowing and insert it back to the grid when required. Unluckily, electricity is a challenging and costly commodity to keep. 

Thus far, the most effective currently accessible answer to storing extra electric energy is to use it for pumping water adjacent to the gravity into a reservoir.
