America’s least and most environmentally friendly states. The figures this article gives don’t make sense. For example, #32, New Jersey says the fossil fuels and renewables add up to 5% total. Where is the remaining 95% of the energy coming from? They say the figures come from the government – EIA. There seems to be

This is an animated graphic of global primary energy consumption by source. Interesting. https://www.facebook.com/TheInfographicsShow/videos/256670979610323/
Scotland missed the 100% clean electricity consumption by only 1.4%. https://electrek.co/2021/12/31/scotland-clean-electricity-consumption-2020/
From a reply in FB group TSLA… Hydrogen fuel cell vehicles will be very common once the electric grids are powered predominantly by renewables. The price of hydrogen will conform to Wright’s Law and be so cheap that it will be competitive with BEVs. And due to the electric grid powering what is now still

OMG! China is expected to install 1200 GW of solar and wind by 2026! To give you an idea of how huge an amount that is, the total electric generation for the United States is about 1200 GW! That is an enormous amount! Quote from article: << China is expected to install 1,200 GW of

Engineering with Rosie dives into the VALCOE – value adjusted levelized cost of energy. This is adjusted for time of use – most solar is available only during daylight hours. https://youtu.be/6_BGHy4sfMs She uses a car race analogy to compare the solar, onshore wind, coal and gas. Solar and wind win the race. One thing I

My comments to Dave Borlace’s JHAT Plus a chart of levelized costs of energy for both conventional and renewable energy. << Thanks, Dave, for the informative video. Nuclear reactors are safe *per TWh* while in operation. The real issues are at the beginning and the end. The beginnings, as you stated, are the huge cost

A 24 min YouTube video: Generation of ammonia using solar energy: GCEP symposium Jens Nørskov Oct 8, https://youtu.be/FayZdrPx6xo Most fertilizer is made from ammonia. Humanity is heavily dependent on fertilizer for growing food. 1% of the world energy is used in the Haber-Bosch process to make ammonia. High energy: not as high as gasoline but

There is a growing body of citizens who want the US government to stop subsidizing the fossil fuel industry. But the government really could use the subsidies to the advantage of clean energy. Instead of ending subsidies, which would end up costing more for consumers, we should require Big Oil and fossil fuels to invest

Rooftop solar makes South Australia the world’s first gigawatt-scale system to hit negative demand. One thing that angers me is that they said they may have to shut off some rooftop solar to cut back the supply. That “curtailment” should be made illegal. The law should require that all excess renewables generation be used to
