The U.S. Will Need a Lot of Land for a Zero-Carbon Economy By Dave Merrill Published: April 29, 2021 | Updated: June 3, 2021 https://www.bloomberg.com/graphics/2021-energy-land-use-economy/?s=03 Corrects wind turbine spacing estimates in the 2nd paragraph, clarifies attributions to data sources and references projections from alternate studies. At his international climate summit in April, President Joe Biden vowed to cut U.S. greenhouse gas emissions in half by 2030. The goal will require sweeping changes in the power generation, transportation and manufacturing sectors. It will also require a lot of land. Wind farms, solar installations and other forms of clean power tend to take up more space on a per-watt basis than their fossil-fuel-burning brethren. A 200-megawatt wind farm, for instance, might re...
Batteries And The Environment

Batteries And The Environment Nicholas Tesla said it best when he called it an Energy Storage System. That's an important distinction. Batteries do not make electricity – they store electricity produced elsewhere, primarily by coal, uranium, natural gas-powered plants, or diesel-fueled generators. To say an EV is a zero-emission vehicle is not at all valid. Forty percent of the electricity generated in the U.S. is from coal-fired plants, it follows that forty percent of the EVs on the road are coal-powered. Einstein's formula, E=MC2, tells us it takes the same amount of energy to move a five-thousand-pound gasoline-driven automobile a mile as it does an electric one. The question is what produces the power? To reiterate, it does not come from the battery; the battery is only the storage device, like a gas tank in a car. There are two types of batteries, rechargeable, and single-use. The most common single-use batteries are A, AA, AAA, C, D. 9V, and lantern types. Those dry...

While everyone gripes about the ridiculous gas prices ...and thinks the future is electric……. Well there’s a long way to go. Yes I love my Tesla, around town it’s fun and sporty, extremely economical, and a great looking car that needs no maintenance and only a full charge once a week that I can do at home. But you aren’t always at home….. See that’s where we are many many years behind in the electric industry and I believe the wagon will be put in front of the horse if things do not change…. But that’s kinda become the standard in this administration, big aspirations with no planning and even worse execution. This picture here is my car at a Tesla Supercharger. I’ll type this while I wait 20-30 mins to charge and continue my trip. This process will add approximately 1-1.5 hours to my total trip of 400 miles. In my wait I’ll make this post. I’m occupying 1 of 8 chargers for :30 mins. Rarely do I see a full charging station but I haven’t been to bigger ...

Makes you think about going green This is an excellent breakdown. Batteries, they do not make electricity – they store electricity produced elsewhere, primarily by coal, uranium, natural gas-powered plants, or diesel-fueled generators. So, to say an EV is a zero-emission vehicle is not at all valid. Also, since forty percent of the electricity generated in the U.S. is from coal-fired plants, it follows that forty percent of the EVs on the road are coal-powered, do you see?" Einstein's formula, E=MC2, tells us it takes the same amount of energy to move a five-thousand-pound gasoline-driven automobile a mile as it does an electric one. The only question again is what produces the power? To reiterate, it does not come from the battery; the battery is only the storage device, like a gas tank in a car. There are two orders of batteries, rechargeable, and single-use. The most common single-use batteries are A, AA, AAA, C, D. 9V, and lantern types. Those dry-cell species u...
