It may be slightly different now 1 year later but this EIA chart from 2017 shows wind energy in the USA has finally surpassed wood at 2.3 % of total energy.
.
Solar is .66%

Let's keep the discussion true people.

Thanks!
*I wanted to limit the conversation to 'domestic production',as it reflects what we produce here at home.
*US electrical production is lower than what we consume.
*US natural gas production falls short of what we consume.
*US coal production is short of consumption.
*US petroleum production is short of consumption.
------------------------------------------------------------------------
*When 'renewable' is criticized for it's inability to meet 'demand',well,we'd have to say the same for Petroleum,Natural Gas,Coal,and 'Conventional' electricity.They can't meet demand either.And haven't been.
------------------------------------------------------------------------
*And considering that we'll never have to have the US Seventh Fleet escort shipments of sunshine or wind to the United States ,our national security situation looks a bit brighter.
OPEC can't embargo the sun or wind,and throw us into another energy crisis,as in past times.
-------------------------------------------------------------------------
We also don't have to dig a hole in the ground,extract,then ship sunlight or wind 1,500-miles to a power plant on a railroad,dead-heading 1,500-miles on the return trip,back to the hole in the ground, with an empty train to get more.
We'll never see $140-barrel electricity either.
If you want a 100-mpg car,you can buy 'em today.They won't have pistons though.
-------------------------------------------------------------------------
I don't see a problem meeting America's energy 'needs' with renewable.
I do see a major hurdle meeting America's 'wants.'
And I think Americans should learn how to differentiate between the two.

Yeah wen talking about total energy fire wood makes solar look like a joke.

Absolutely!
EIA credited 'biomass' with 5.04-quads in 2017.
Solar only came in at 0.77-quads.
Geothermal,only 0.21-quads.
I suppose they never attempted to quantify passive-solar,with super-insulated,earth-sheltered construction.

Is the hedgerow growing better just because the soil hadn't been tilled when there was a fence there? Or because it had never been in production so all of it's Nitrogen, Phosphorous, and Potassium was still laying there from it's own compost?

I saw it as an argument for (no-till) permaculture. And the symbiosis of grass roots and fungus. Plowing ruins that.

Salmon runs. The counter-argument would be the Salmon cannon.

It's off-topic but here's Anton petrov on 'terraforming' mars using sulphur hexafloride manufactured on Earth to jump-start a greenhouse effect from the local CO 2
This may be the solution to the oncoming Ice Age.

There are many well meaning but underinformed groups speaking out against hydro dams. Some have even proposed to specifically state a con position in any official documents concerning a Green New Deal. Here is one. Just the first thing that came up on a search.
.
https://www.americanrivers.org/threa...amaged-rivers/
.
But people don't realize that big hydro is our best non-carbon power source. Dispatchable immense 24/7 power. In the mid future, big hydro electrical plants will be the most effective area to build big refineries such as Aluminum production since they will be the only locations with ready 24/7 power.
.
I believe that we should use our remaining fossil energy wealth as "seed corn" to build out as much hydro, solar and wind (GenIV nuclear would have been nice if we would have continued it's development in the 80's. But now it is getting late) as possible. Along with terracing land for an eventual return to more local and muscle powered food production (crop yields will necessarily decline), building out electric rail so that we can still have efficient transportation and gravity electricity storage, building out super efficient new housing for some of the billion who will leave their "jobs" in the mega cities to "work" growing food, fuel wood, and fiber.
.
Countries with the lowest CO2/ kWh emissions are either nuclear or hydro. ie Norway, Brazil, Costa Rica, New Zealand, Quebec, Sweden, France, Ontario.

It is better because it hadn't been tilled.
Watch all of the talk - when the cows eat the grass, with the right management - the soil gets better and better over time. Sinking carbon into the soil, means that the soil GAINS nutrients, because the rhizomes are more vigorous. The soil gains more capacity to hold water - which reduces flooding, and extends resistance to drought.
People can eat cows.

I've always wondered why aluminum production requires large quantities of electricity. Can't they use natural gas for heat?
Anyhow, I don't follow the Green New Deal since I don't follow the news, but the tidbits I do see make it clear that it's DOA. It's a race to the bottom of bad ideas, and they'll end up eating their own. Wanting to tear out hydro plants is an example of this. You'll finally get someone saying we should make it illegal to procreate and the bottom will fall out of this movement that history will quickly forget.

The Hall–Héroult process pretty much the electrolysis of an molten aluminum sodium salt mix in the presence of graphite electrodes.

Constructing new wind and solar projects would be less expensive than continuing to run 74 percent of existing U.S. coal plants, according to a new study. That number jumps to 86 percent of coal plants by 2025.
