Well I can't write an essay but I can give you some points:
-Renewable electricity isn't much(1 wind turbine can only power THREE houses)
-It looks really ugly(Just imagine a beautiful bay then you stick some wind turbines in the sea and it instantly looks ugly)
-Too expensive to build(solar panels are not cheap)
There's also another reason I didn't write your essay, it's because I suck at writing essays. I always end up putting a bunch of fancy and bombastic words that the teacher doesn't understand so she marks it wrong. I'm really sorry!
Urbanisation means that many new roads and buildings were build. It makes life easier for people. On the other hand it hurts nature, because you need to get rid of forests to build
