I get where you're coming from. It appears to be 'green technology is not a perfect solution.' Duh. It is valuable to explain why, to help people understand something that is both very new and very important. It helps green technologies become closer to perfect, which they are doing steadily. But, even if not intended, you come off as a bit of a detractor. The last thing we need is to feed those who will take any comment and turn it against technologies to which they are ideologically opposed. Being in the solar industry I'm sure you've encountered plenty of those. Be honest, but don't feed the trolls.
