"However, the mechanisms for dealing with funding applications must be set up to allow fast responses to proposals.
"The green economy is moving very fast and there are lots of current opportunities, so funding must be readily available in order to take advantage.
"Numerous private equity funds have been launched recently to invest in the green economy - they are commercial organisations who do react quickly to opportunities - it might be that they bring more success than the Green Investment Bank.
"The one major issue causing concern amongst investors and financiers in the sector is the Government's review of the incentives measures and how they are delivered.
"The green economy has so much potential, but this can only be underpinned by the Government giving confidence that the incentives will remain at the current levels for some considerable time."
