Thread: What could b the energy source for next generation?

The cost of solar energy is still high. The process to get sea energy is still under development.

But, scientists from California and Korea have successfully stolen an electric current from algae. The research could eventually create a new and environmentally friendly way to generate electricity.

But the qsn is, is this little current enough for the whole world? Do you think that, the little algae can supply current to the whole world?
