In July, Denmark made the absolute most out of a particularly windy 24 hours by harnessing its power and producing not only all of its own electricity needs for the day, but enough extra to spread between three neighboring countries. To be exact, the sustainable wind-power technologies harnessed and collected 144% of one days electricity needs.
Denmark had previously developed its wind-power plants but on that particularly windy day, it reached 116% of its domestic electricity demands through wind farms and then exceeded even that impressive surplus, reaching 140%, causing Denmark to export excess power to Norway, Germany, and Sweden.
80% of the excess energy surplus was given in equal parts to Norway and Germany and Sweden received the remaining 20%. Germany and Norway possess hydropower systems with storage capabilities and were thus able to store the extra away for later use.
80% of the power surplus was shared equally between Germany and Norway, which can store it in hydropower systems for later use. Lucky Sweden received the remaining fifth of excess power. Oliver Joy, a spokesman for trade body the European Wind Energy Association:
“It shows that a world powered 100% by renewable energy is no fantasy. Wind energy and renewables can be a solution to decarbonization – and also security of supply at times of high demand.”
Take a look at this graphic below which reveals that on the day when 140% of the power needs were produced, the systems weren’t even functioning at 100% of their potential power. The Danish transmission systems operator, emergent.dk provides minute by minute constant reading of the renewable power in the national grid system provided this information, saying that the full capacity is 4.8GW. This is quite amazing.
