Ehhhmmmm, the tech for renewable energy has been around for a decade. Why is it till now it solar and wind power hasn't been utilized 100% and countries are still relying on gas and oil. Seems like countries are shooting themselves in the foot. Every single appliance, vehicle and power should be solar powered by now. We've had solar powered calculator since the 90s! How hard was it to replicate that on a larger scale? Humans are able to put men on the moon but can't figure out how to convert sun rays to energy? What's wrong with this picture?
