Elon Musk Tells Governors About Solar Power & US Gigafactories

July 19th, 2017 by Steve Hanley

Solar In The US

Elon Musk at NGA“If you wanted to power the entire U.S. with solar panels, it would take a fairly small corner of Nevada or Texas or Utah. You only need about 100 miles by 100 miles of solar panels to power the entire United States.”

Of course, some grid storage capability would need to be included. Musk has an answer for that, too. “The batteries you need to store the energy, to make sure you have 24/7 power, is 1 mile by 1 mile. One square mile. That’s it.

Why is Musk so high on solar? Because it’s there, it’s free, and it reliable. “People talk about fusion and all that, but the sun is a giant fusion reactor in the sky. It’s really reliable.  

It comes up every day. If it doesn’t, we’ve got bigger problems,” he joked.

Agelbert NOTE: Check out the comments at the link. The educated folks there take the fossil fueler troll naysayers apart piece by piece.

Also, some great stats on earth's land area and use, along with some excellent solar panel appliications for preventing evaporation of hydroelectric power dam surface water are mentioned. Enjoy!

At $200/sqmeter that is 4 trillion for the PV, at $500/KWHr of battery that is 8 trillion for the battery, at a billion dollars per 200km of transmission of 2GW and 2.5 trillion for transmission lines for a grand total of 12.5 trillion dollars. With an average net weighted life time of 30 years (shorter for battery and longer for transmission lines) and 3% interest rate we get 750 billion dollars per year not including local distribution. Or about $7000 per worker per year. This does not include transport fuels, home heating, industrial energy use. About a factor of three for all that give $21000 per worker per year for US energy from solar.

 


Have you entirely lost your mind? Listen, Einstein, before you start crunching your incredibly inaccurate numbers for Renewable Energy solar and battery backup powered US grid, I suggest you LOOK INTO the MTBF of EVERY internal combustion engine out there NOW that moves people, things and provides power for and power backup for the grid and hospitals.

After you find out the GARGATUAN amount of money that costs NOW to operate, maintain and replace those polluting PIGS (never mind the HORRENDOUS Social Costs of Carbon that SHORT TERM PROFIT STUPIDITY is DUMPING on we-the-people that INCREASES MASSIVELY our health care cost, LOWERS work attendance (i.e. PRODUCTIVITY) and generally makes it MORE COSTLY to grow crops), THEN we can talk about comparing numbers.

There is only one thing I can say about your ridiculous number mumbo jumbo, straw grasping attempt to deride the Renewable Energy solution (SEE BELOW):


Unlike Edpell  , who can only sound the Death knell,
objective people know better.  

Agelbert NOTE: Edpell, DO NOT comment unless, and until, you have completely read the following post (see below). I will delete your post if you do. I will delete your post if you try to pump more unsubstantiated disinformation bullshit on this thread. Have a nice day, Fossil Fuel defending TROLL.


100% Clean, Renewable Energy Is Possible    — Setting The Record Straight

July 22nd, 2017 by Karl Burkart


SNIPPET:

Since 2009, Mark Jacobson, Professor of Civil and Environmental Engineering at Stanford University and Senior Fellow at the Woods Institute for the Environment and Precourt Institute for Energy, and more than 85 coauthors have written a series of peer-reviewed journal articles evaluating the scientific, engineering, and economic potential of transitioning the world’s energy infrastructures to 100% clean, renewable wind, water, and solar (WWS) power for all purposes by 2050, namely electricity, transportation, heating, cooling, and industrial energy uses.

These papers have helped to shift the global conversation around the possibility of completely decarbonizing the world’s energy sector through renewables. They have helped to motivate a wave of 100% renewable energy commitments by over 100 cities and subnational governments, including 35 cities in North America, 100 large international companies, and 48 countries. California, the world’s 6th largest economy, just announced its 100% by 2045 renewable target and proposed U.S. House Resolution HR540, U.S. Senate Resolution SR 632, and U.S. Senate Bill S.987 calling for the United States to go to 100% clean, renewable energy by 2050.
