With a lot of efforts being made to shift to renewables as major sources of power, there has been a lot of concern whether it can effectively compete and finally replace other methods of energy generation. Indeed, there has been an increase in the amount of renewable energy generated and added into the energy mix, with global figures showing that 143 gigawatts of renewable energy were added in 2013. It is expected that the rate will shoot to four times the current rates by 2030.

To begin with, popularity of renewable energy generation sources is due to their low environmental impacts - this is the most important reason they have been aggressively pursued even to date. Renewable energy is the perfect way to avoiding a climate change fueled by a 2 degrees Celsius benchmark rise in global temperature.
There has been no other time when governments and non-governmental organizations have raised up against acts that damage the environment like in the last few years. However, there is no doubt that the world started at a challenging point with regard to pricing of renewable energy although proponents still think that renewable energy is cost-effective on a long term basis.
