What I’m more worry about those Renewables stuff is their ressource footprint , when you look at how much « rare earth » « composite » material is needed to build just one its seems like a nonsense to use wind their are many documentaries on this topic. Today the vast majority of those turbines are not recycled. On top of that wind being intermittent you need gas power plant to provide. France power provider RTE esti…

So you're also being downvoted for raising a good question. Nuclear is much greener that renewables, nuclear emits less CO2 per watt. Building a wind turbine on a large floor of concrete, building batteries and solar panels all the material that comes with it... Fossil fuel benefits from renewables.

One similar thing regarding both nuclear and wind power plants is no one wants one in their backyard.

How does that help on mobile where I don't see the URL by default. The headline should specify US if it's only for US.

I'm on mobile. I see "energy.gov" just fine.

Wind energy blows, rotors are not recyclable so they just get buried. nuclear energy is the greenest energy, as long as they are built in safe places.

> rotors are not recyclable so they just get buried.

Fortunately nuclear has no similar issue, right?

False and misleading. First, it only refers to the US, while the headline makes no such qualification. Second, this refers only to electricity generation, which is roughly 25% of US energy use, or 20% if you include energy embedded in imports, mostly fueled by fossil fuels in China. Third, this refers only to gros capacity. For those who have been asleep, the effective energy capacity is far lower for renewables than…

The first two lines of the article, emphasis added:

> The Land-Based Wind Market Report: 2021 Edition provides an overview of developments and trends in the U.S. wind power market.

> A record 16,836 megawatts (MW) of U.S. wind capacity was installed in 2020, bringing the cumulative total to 121,955 MW.

Asking a US government to put in the headline that the report is about US stuff is a bit surprising.

Am I correct to assume that wind is a more indirect source of power than solar? In my mind, solar energy creates wind by heating up the surface of the earth, which then heats up the air above it, which then moves around to even out the temperature differences. Therefore I suspect that in the long run (10 years? 100 years?) solar energy will be more common than wind energy. Similar to how solid state drives are overta…

Most of our energy sources (except nuclear and geothermal) are forms of solar. Wind, hydro, and fossil fuels are all just stored solar energy! The fact that they’re stored energy is what makes them particularly useful, though. If we were exclusively using solar directly then we’d need to store it ourselves, or build a global distribution grid to move energy from where it’s sunny to where it’s needed.

If you go back far enough in time, everything is stored solar energy, but at even larger time frames than fossil fuels.

https://en.wikipedia.org/wiki/Coal#Formation: “Although coal is known from most geologic periods, 90% of all coal beds were deposited in the Carboniferous and Permian periods”

That was 300 million years ago.

https://en.wikipedia.org/wiki/Uranium#Origin: “uranium is only naturally formed by the r-process (rapid neutron capture) in supernovae and neutron star mergers”

That happened 6,5 billion years ago.

Geothermal is about 50% radio-active decay and 50% left-overs from when earth was formed (https://en.wikipedia.org/wiki/Earth%27s_internal_heat_budget: “Earth's internal heat budget […] comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat left over from the formation of Earth.”

I'd love to have a nuclear plant in my backyard.

Also it might be a cloudy area.

To be fair US government could talk about global trends.

My problem is with the title by the hackernews poster. Highly misleading, as your quotes show.

Isn't this only for US? Can you please change the title?

This is (somewhat poorly) implied by the fact that TFA is hosted by energy.gov, AKA the U.S. Department of Energy.

(Kind of a bummer that only U.S. agencies of government can use .gov)

France does run mostly on nuclear, but the less money claim needs some serious evidence. The reason why France can export energy more cheaply is because the cost of nuclear is pretty much all capex, so now that they have their plants it makes sense to constantly (nuclear plants can't easily be adjusted to load) run them at a high output and export excess energy. However, the overall cost is very likely much higher (t…

Aren't renewables heavily subsidised?

The LCOE of unsubsidized newbuilt renewables are currently getting below the marginal cost of existing nuclear and fossil infrastructure.
