Wind, solar and tidal - or whatever - have a host of challenges. Chief among them are requiring symmetrical, on-demand power from a plant powered by hydrocarbons, hydropower, or nuclear. The obstacles to nuclear are primarily political and regulatory.
Why is mining for material necessary for alternate energy production acceptable but not hydrocarbons? Don't we have to assess the total energy expended and environmental impact from mining, processing, energy production and end of life disposal and renewal of both to legitimize 'green'?
The U.S. is not a large producer of these materials. Manhattan Institute claims green machine energy needs require 10X more mineral extraction for the same output as hydrocarbon. I don't know if that's legit so let's say it's half; are we prepared for a 500% mining increase in this country? According to the left, as this most 'progressive president ever' promised, that answer is 'no'. What countries are mining these materials? These questions dismantle a host of green arguments, particularly these claims:
1.)
We won't have to send U$D abroad - we either will or enormously increase U.S. mining
2.)
We'll have energy independence and won't have to rely on wicked countries for it - same as #1. And the wicked countries are the largest producers of what we'd need.
3.)
A better environment and stopping climate change - no, this is where green advocates deviate to 'Think Local and Ignore Global', NIMBY just means outsourcing the nastiness you don't want to see; "Yay! - green!". Or that one is so hypocritically cynical to choke other countries but preserve their own. Vast plumes of smoke and metric tons of toxic wastewater don't think local, but rather
act global, don't they?
Green farms are damnable blights on the landscape and rapine of environmental habitat. T. Boone Pickens Pampa Wind Farm in TX panhandle would have covered a land mass of 400,000 acres - or 80% of the Great Smoky Mountains N. Park. - to power 1.5 million homes. When the wind blows.
There are around 140 million residences in the country; we'd need 37 million acres of wind farms just to power U.S. residences. Then there's commercial power for business. And you still need symmetrical, full-demand capacity hydrocarbon, hydropower, or nuke stations
I think It indicates climate and environment are not the actual concern, but is an anti-capitalist, quasi-Marxist primitivism bent on chopping the legs out from under the U.S. and the West generally. For decades, we've been seesawed from one climate emergency to another. It was cooling, it was warming - climate change do not occur in such a brief time span; man is impacting it.
We know better than that now. People should read on 'abrupt climate change', in which enormous global shifts have occurred in as little as 1-2 years, and have done so multiple times. Climate alarmists still use the argument, though.
I think instead of chasing our green energy tail, we should continue to abundantly deploy the mature hydrocarbon technology we have and and focus on efficiency gains, and deploying nuclear, the greenest energy. While we're doing so, green energy can continue to trundle along entertaining itself on it's own dime.
That is not incompatible with being good stewards of the earth.
Green Energy Reality Check: It's Not as Clean as You Think | Manhattan Institute (A very lengthy article)
Among the material realities of green energy:
- Building wind turbines and solar panels to generate electricity, as well as batteries to fuel electric vehicles, requires, on average, more than 10 times the quantity of materials, compared with building machines using hydrocarbons to deliver the same amount of energy to society.
- A single electric car contains more cobalt than 1,000 smartphone batteries; the blades on a single wind turbine have more plastic than 5 million smartphones; and a solar array that can power one data center uses more glass than 50 million phones.
- Replacing hydrocarbons with green machines under current plans—never mind aspirations for far greater expansion—will vastly increase the mining of various critical minerals around the world. For example, a single electric car battery weighing 1,000 pounds requires extracting and processing some 500,000 pounds of materials. Averaged over a battery’s life, each mile of driving an electric car “consumes” five pounds of earth. Using an internal combustion engine consumes about 0.2 pounds of liquids per mile.
- Oil, natural gas, and coal are needed to produce the concrete, steel, plastics, and purified minerals used to build green machines. The energy equivalent of 100 barrels of oil is used in the processes to fabricate a single battery that can store the equivalent of one barrel of oil.
- By 2050, with current plans, the quantity of worn-out solar panels—much of it nonrecyclable—will constitute double the tonnage of all today’s global plastic waste, along with over 3 million tons per year of unrecyclable plastics from worn-out wind turbine blades. By 2030, more than 10 million tons per year of batteries will become garbage.
