What will it take for green energy to overtake fossil fuels as our main source of power?

[Natural News]: Japanese researchers from three prestigious academic institutions took a hard look at the kind of technology needed by the hydrogen-based green energy industry to successfully compete with the fossil fuel energy industry.

They estimated that Japan needs a new generation of cheap rechargeable batteries to produce clean, renewable fuel at cost-effective rates. Aside from the technology levels, the joint study also considered the economic efficiency of hydrogen production systems. These systems get their energy from solar farms and store excess electricity in rechargeable batteries...read more>>>...
