November 02, 2018 Electric Buses On The Rise
https://earthwiseradio.org/wp-content/uploads/2018/10/EW-11-02-18-Electric-Buses-on-the-Rise.mp3
Electric buses are replacing conventional diesel-fueled buses at an accelerating rate that is outpacing the adoption of battery-powered cars. According to forecasts by Bloomberg New Energy Finance, by 2030 some 28% of car sales will be electric vehicles while 84% of new buses will be electric buses. So far, some 12 years away, the actual adoption of electric buses is outpacing this optimistic projection.

Our planet has been through five upheavals over the past 450 million years. During each one, the environment on earth changed so dramatically that most plant and animal species became extinct. After each of these mass extinction events, evolution slowly filled the gaps in the environment with new species.

October 30, 2018 A Battery That Eats Carbon Dioxide
https://earthwiseradio.org/wp-content/uploads/2018/10/EW-10-30-18-A-Battery-That-Eats-CO2.mp3
Fossil fuel-based power plants are increasingly considering the use of carbon capture technologies as a way to reduce emissions. The biggest challenge to the wide-spread adoption of such technology is its energy cost, which of course equates to economic cost. Present-day power plants equipped with carbon capture systems can use up to 30% of the electricity they generate just to power the capture, release, and storage of carbon dioxide.
