“”The expansion of solar energy has always carried one tension with agricultural nations that no policy document resolved cleanly: solar farms require land and farmland is finite. Germany found a way to make that tension irrelevant by installing solar panels above active crop fields in an approach called agrivoltaics where the same land produces food

“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

“”An Oxford University study found that shifting the global energy system to a near zero-carbon model by 2050 could save the world more than 12 trillion dollars compared to continuing with fossil fuels. The research shows that clean technologies like solar, wind, batteries and electric vehicles are becoming cheaper much faster than expected, making the

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

The Upgrader: “”Unsustainable fossil fuel systems are costing nature an estimated $5 billion every hour, according to a major report by the United Nations. That translates to nearly $45 trillion in environmental damage each year, a staggering figure that reflects the hidden costs of how energy is produced, transported, and consumed across the globe. These

Plans to change unused farmland in California to a 21 GW solar project, probably the largest in the world. https://www.facebook.com/reel/968024809035097/?mibextid=CDWPTG
Iowa has the highest percentage share of wind energy of any state. However Texas gets much more Megawatts of wind. https://www.facebook.com/story.php?story_fbid=pfbid02gXQiZJUiaWDaPbxe7m9QcuWCxwbK8tyG2w6CcBe8SHqQfJLFWV7JwrXS9Yujgbrxl&id=100093822948697&post_id=100093822948697_pfbid02gXQiZJUiaWDaPbxe7m9QcuWCxwbK8tyG2w6CcBe8SHqQfJLFWV7JwrXS9Yujgbrxl&mibextid=CDWPTG
Planned coal retirements last year totaled 8.0 gigawatts. Only 2.6 gigawatts actually shut down. Why did the U.S. Department of Energy step in? Because reliability warnings are getting louder. In its latest assessments, the North American Electric Reliability Corporation (NERC) warns that large portions of the Midwest face a high risk of electricity shortfalls during
