  Renewable energy is an innovative and transitional solution that can become a policy, technological, and economical driver in the future targeting drastic greenhouse gas emissions’ reductions and sustainable development.  Here’s a deeper look into each aspect shaping its trajectory: #1 Solar and Wind Energy Evolution: Technological Efficiency: Smart Solar PVs are evolving and with an introduction of new similar material in solar cell such as perovskite they are achieving better efficiency while are cheaper.  Wind technology is growing; today there are offshore wind farms, which utilize larger turbines to capture more powerful, constant winds. Cost Reductions: The cost has come down due to economies of scale, improved manufacture and many other factors.  It may come as a shock to many to learn that solar is now amongst the cheapest sources of energy across most regions of the globe, thereby fuelling the constant improvement.  Cost of wind energy is also coming ...
