“Engineering With Rosie” Barnes explains why EV batteries usually last longer than the car. Determining SOH = state of health. Testing for SOH. Thermal issues. Buying used EVs. The EV batteries are guaranteed for 8 years so the risk is lowered when buying a used EV. She mentioned that there are outliers. Occasionally a used

This Grist article makes some very good points. Important! “Insulate, insulate, insulate.” “Double pane windows.” “Do not burn fossil fuels in your home. Install heat pump HVAC.” However it says, “… Heat pumps join electric vehicles and induction stoves in increasing demand on the grid.” I don’t agree. The heat pumps should reduce the amount

Chinese researchers converting coal directly into electricity by an electrochemical process. Needs many more years for development. The problem is it’s still a finite resource being used up. And there is still the waste left over. Solar and wind are infinite and free. https://www.facebook.com/story.php?story_fbid=pfbid028ZMxJRtnzemcj46uq9d4umqztWpJDeWnuGLhaSo2dcE1erQqvW4xeRK1UZyYxsfJl&id=100064453789721&post_id=100064453789721_pfbid028ZMxJRtnzemcj46uq9d4umqztWpJDeWnuGLhaSo2dcE1erQqvW4xeRK1UZyYxsfJl&mibextid=NOb6eG

Just how wasteful is fossil fuel? Most people think about what happens inside the engine… But the real waste starts LONG before the fuel even reaches your car. To make just 1 litre of petrol /gasoline: Around 1,700-3,400 kJ (0.5-0.95 kWh) is used just to get crude oil out the ground. Then another 3,400-6,800 kJ
