  • Perovskite solar cells are an emerging type of solar technology that's more efficient than current photovoltaic technologies, but hasn't yet been adopted due to problems related to cost and stability.
  • In a recent study, scientists treated perovskite solar cells with small amounts of capsaicin, finding that the compound improved both stability and efficiency.
  • In 2022, a British startup plans to bring perovskite solar cells to market for the first time.

  • Swedish space agency allows Harvard researchers to test a stratospheric balloon next year.
  • The balloon may eventually be used to release particles into the atmosphere to reflect sunlight.
  • The goal would be to cool Earth and fight back against global warming but the approach has critics.

  • The International Energy Agency is an intergovernmental organization that advises member nations on issues related to energy and the environment.
  • In its annual report, the IEA reported that the cost of solar is dropping more rapidly than previously thought, providing some parts of the world with historically cheap electricity.
  • The IEA predicted that, over the next decade, renewables will meet 80 percent of global electricity demand growth, while the demand for oil will peak.

  • Part of what makes fighting climate change so hard is that solutions take years or even decades to develop.
  • Meanwhile, the amount of CO2 already in the atmosphere means that climate change has momentum on its side, and its effects are already being felt.
  • However, quantum computing would represent a breakthrough that could cut down on the time needed to research and develop solutions exponentially, turning the work of decades into years or less.
