The IEA's Tracking Clean Energy Progress (TCEP) reports assess the status of 46 critical energy technologies and sectors and provides recommendations on how they can get 'on track' with the IEA Sustinable Development Strategy (SDS).
"Power sector emissions declined by 1.3% in 2019, while emissions intensity decreased 2.5%. These trends are the result of greater generation from low-carbon technologies (+5.6%) and a decrease in non-abated coal (-3.1%) being offset by a 2.5% increase in gas-fired generation. This sector’s transformation is critical to clean energy transitions, as power generation accounts for 41% of energy-related CO2 emissions and electricity is increasingly used to meet end-use energy demand. Unfortunately, recent trends are not on track with the SDS, which requires that power sector emissions fall an average 4% per year to 2030 and electricity emissions intensity drops 5.6% annually."
A research team led by Prof. Yi-Chun LU, Faculty of Engineering, CUHK, has taken a critical step forward in improving high-energy batteries by introducing a novel electrolyte to the aqueous lithium-ion (Li-ion) battery. This electrolyte is commonly used in skin cream. It is inexpensive, non-flammable, less toxic and is eco-friendly, yet can create stable voltage for common usage.
