Oh well done you can quote Steve Fielding quoting Fred Nile quoting John Anderson.joseph777 said:The Greens: green on the outside but red on the inside.![]()

That's four years away, if not more. Great technology, but it's still not currently competitive.Trefoil said:For those who for some reason think solar power isn't competitive in the market: you'd be wrong.
Pretty sure JB_NC posted a full lifecycle carbon output and photovoltaics are hell of bad in that regard.Trefoil said:That particular technology is at most 4 years away, but it's one element of a popular industry which has many potentially competitive research products as well as currently competitive market products.
Id est: many forms of photovoltaics are already market competitive (and many are not). Any all inclusive claims about solar not being competitive are thus delusional.

http://en.wikipedia.org/wiki/Photovoltaics#Greenhouse_gasesLife cycle greenhouse gas emissions [for photovoltaics] are now in the range of 25-32 g/kWh and this could decrease to 15 g/kWh in the future. For comparison, a combined cycle gas-fired power plant emits some 400 g/kWh and a coal-fired power plant 915 g/kWh and with carbon capture and storage some 200 g/kWh. Only nuclear power and wind are better, emitting 6-25 g/kWh and 11 g/kWh on average. Using renewable energy sources in manufacturing and transportation would further drop photovoltaic emissions.
