Rhodium Group estimates US GHG fell 2.1% in 2019, driven by coal decline

Green Car Congress

This decline was due almost entirely to a drop in coal consumption. Coal-fired power generation fell by a record 18% year-on-year to its lowest level since 1975. An increase in natural gas generation offset some of the climate gains from this coal decline, but overall power sector emissions still decreased by almost 10%.

Rice team develops plasmonic photocatalyst for one-step light-driven conversion of H2S to hydrogen and sulfur

Green Car Congress

An illustration of the light-powered, one-step remediation process for hydrogen sulfide gas made possible by a gold photocatalyst created at Rice University. Each island was a gold nanoparticle about 10 billionths of a meter across that would interact strongly with a specific wavelength of visible light. —Naomi Halas.

A Skeptic’s Take on Beaming Power to Earth from Space

Cars That Think

Energy experts have been warning that electricity is likely to get more expensive and less reliable unless renewable power that waxes and wanes under inconstant sunlight and wind is backed up by generators that can run whenever needed. These rectennas would then convert the signal to usable DC electricity.

Mad Power thoughts

EV Info

Wind farms stand idle for days on end, a fire interrupts a vital cable from France, a combination of post-Covid economic recovery and Russia tightening supply means the gas price has shot through the roof – and so the market price of both home heating and electricity is rocketing.
