I also feel sorry for you because you are poorly informed, so I am going to give you some names of websites that you can use.
The first 3 are aggregaters that list renewable energy news: Utility Dive, Clean Technica, Governors Wind Energy Coalition. Governors cuts and pastes everything onto their website so you don't have to worry about paying or registering to read an article.
Enviro websites are a dime a dozen but here are two that are very credible: Green Tech Media and Inside Climate News.
The old Google News Search is still a good way to search a keyword like renewable. The new Google news site is limited.
On any reasonable comparison of non-subsidized cost wind & solar, (and batteries if that tickles your fancy) are not even close to cost efficiency of fossil coal & gas. Most particularly in Michigan.
you’re the one who made the unsubstantiated BS claim that fossil fuel prices are rising and “renewable” energy prices are falling, so proof it, otherwise we all know you can’t and you’re just making up fake stuff ...
