Current State of Clean Energy
“The world’s energy system is being pushed to breaking point. Energy-related CO2 emissions are at historic highs, and under current policies, we estimate that energy use and CO2 emissions would increase by a third by 2020, and almost double by 2050. Many clean energy technologies are available but they are not being deployed quickly enough to avert potentially disastrous consequences.”
