The U.S. government plans to end purchases of gas-powered vehicles by 2035 in a move to lower emissions and promote electric cars under an executive order signed by President Joe Biden on Wednesday. The government owns more than 650,000 vehicles and purchases about 50,000 annually. Biden’s executive order said that light-duty vehicles acquired by the government will be emission-free by 2027. Total federal government operations will reduce emissions by 65% by 2030 under the plan. The government will seek to consume electricity only from carbon-free and non-polluting sources on a net annual basis by 2030 and have net-zero emissions by 2050. The order noted the U.S. government is “the single largest land owner, energy consumer and employer in the nation” and can transform “how we build, buy and manage electricity, vehicles, buildings and other operations to be clean and sustainable.”

Scientists have discovered a way to make ultra-efficient solar cells on a commercial scale using the “miracle material” perovskite.
A team from the City University of Hong Kong (CityU) and Imperial College London made the discovery in a breakthrough that could have major implications for renewable energy production and reaching zero carbon objectives.  Perovskite has been hailed for its remarkable properties compared to tradtional silicon solar cells, however until now they have been too unstable to be suitable for commercial use.  The next-generation cells are expected to cost less, have a much higher power conversion efficiency, and be lightweight and flexible – opening up new applications like coating glass windows with thin layers of solar panels.
