Why is pond scum algae often promoted as a potentially lucrative energy source?

Algae are full of lipids oil which means that they, potentially, at least, could provide a direct and highly cost-effective source for producing biodiesel. Because of its moderate climate and plentiful water supplies, Alabama and other southern states are especially well suited to grow algae commercially. Also, in renewable energy terms, the more appealing strains of algae are found in saltwater.

Some of these saltwater strains conceivably could be grown in saltwater aquifers in western Alabama. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
