HDB exploring floating solar panels in open sea

Click HERE

Other than placing solar panels on the surface of reservoirs, now we're contemplating putting them on the surface of the sea.....
BUT hey, won't this affect our busy shipping lanes? And as with the use of reservoirs, don't we need the reservoirs and the sea for recreation (think kayaking) and appreciating the beauty of nature?

Qns:

1. Assess the view that attempts to control climate change can never be truly effective. (Cam. 2017)

2. Should there be any controls over the production of energy when the need for it is so great? (Cam. 2015)
