brit, I agree, at present the cost of green energy is higher than conventional ones but a time will come when the latter would become so dearer that the former would then become much viable. Yes, its not straight forward now but countries like Germany have taken the lead. They have certain legislations in place that encourage green energy producers, transmitters and users. I wish rest of the world also followed them to ensure a seamless transition in the years to come.

Invest in R/D on making solar cells and deep cycle batteries cheaper, introduce legislation to promote green energy and make sale and purchase of allied items tax free.
