Gavin Hofer Posted about 1 year ago Why are the alternate power sources not being implemented on a world-wide scale? There is a tipping point and we must be close by now!!! It is still more economically viable to produce energy on a large scale using fossil fuels than to use renewable energy. If research and implementation of alternative sources of energy are continued, we will soon reach a point where the falling costs of the alternative sources will meet the rising cost of conventional sources, making renewable energy the more economically viable option. This is the point when renewable sources will be implemented on a world wide scale.
