Hello, I'm Serols. I wanted to let you know that I reverted one of your recent contributions —the one you made with this edit to Pumped-storage hydroelectricity— because it did not appear constructive. If you would like to experiment, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks.

Hello, I'm My name is not dave. I noticed that in this edit to Wind turbine, you removed all the content without explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an edit summary. If this was a mistake, don't worry, I restored the page's content. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. ! dave 21:05, 10 January 2018 (UTC)
