Globally, 2012 saw:
- A shift in investment patterns from industrialized to developing countries
- A decrease in overall clean energy investment in dollar terms but simultaneously saw an increase in installed capacity in gigawatts due to significant technology cost reductions
- Renewables progressively supplementing established electricity systems demonstrating that the implementation of suitable policies can enable the successful integration of higher shares of variable renewables
- The emergence of integrated policy approaches that link energy efficiency measures with the implementation of renewable energy technologies.
