I recently read, and recommend a book titled "Here Comes the Sun" by Bill McKibben. There's a passage where a calculation is made of the amount of minerals that have to be mined in order to build renewable energy to cover all current energy needs. This quantity is huge. However it is equivalent in mass to the amount of fossil fuels that are extracted every year. The major difference is that the equipment for renewabl…

Solar panels etc. will last decades and can and will be recycled afterwards. Further, most materials needed for renewable energy infrastructure (iron, lithium) are highly abundant on earth. Most of the suppliers work to use cheaper (=more abundant) materials in their products, replacing lithium with sodium in batteries and silver with copper in solar panels. Wind turbine blades are produced now using re-solvable resi…

Wind turbines are not recyclable[1]. Besides, the foundations use a massive amount of concrete (nowadays often extracted from the seabed, with all the problematic ecological consequences involved), that stays forever in the ground.

The US invented fracking. Arguably the US is energy independent. It has Texas, Canada and Venezuela. They never did discover any large oilfields in China despite decades of frantically searching for it.

We're only energy independent in the sense that we export more oil than we import. We're still reliant on foreign oil because we haven't retooled (or built enough new) refineries for a lot of the oil we produce. Allowing the Saudis to own refineries is probably a strong factor there. If the middle east and Canada cut us off, we're SOL. Venezuela barely produces anything right now.

Retooling refineries to a different flavor of crude is expensive, but not that expensive. If push came to shove, the US could transition to oil independence in less than a year.

I would love to see photos like these from Australia too one day. We have so much inhospitable land that would be perfect for solar and wind farms. Suncable is trying to do this on a small(er than China) scale. We are just too politically confused and too deep in the belief that mining is the only thing we can do here.

I was just saying this to my colleagues after seeing these. Decades of political sabotage has done significant damage to our transition to renewables. I'm hopeful (perhaps a bit too wishful) that we'll see more of a push for renewables in the coming election cycles, but I'm staying realistic as the last 20 years of climate debate has been frankly shameful. At least rooftop solar is so ubiquitous.

I'm hopeful that the advent of the Teals might generate some momentum here. I believe there are some very large wind farms in progress across NSW too, which is good news. Home solar / battery installations also seem to be on the rise in low density areas (I don't have hard data to back that up though).

I'd also love to see solar panels on top of every Bunnings, Westfield, and other warehouses/complexes, as well as above every outdoor carpark, which would have the added bonus of preventing hand roasting in summer.

It genuinely makes me so sad to see the US not doing the same. Having grown up to the constant beat of “energy independence” as the core goal of a party it seemed obvious that the nearly limitless energy that rains down from the sky would be the answer. But instead we’ve kept choosing the option which requires devastating our, and other’s around the world, community. That’s not to exclude the harsh reality of mining…

Up to the 2008 election the Republican party platform called for reducing fossil fuel use, establishing a Climate Prize for scientists who solve the challenges of climate change, a long term tax credit for renewable energy (with specific mentions of solar and wind), more recycling, and making consumer products more energy efficient. They wanted to aggressively support technological advances to reduce the dependence o…

Oh come on, Bush was the first disaster in the fight against climate warming.

His "win" might be one of the most impactful sliding doors in the human history.

And it would have been possible if not for the support on this platform and similar ones for people like Elon, Jeff Bezos, Mark Zuckerberg and Sam Altman, like the youth says these days: FAFO

One point that gets very little coverage is that fossil fuels are a limited resource. Once they used they are gone. The materials for renewable energy are still in a usable form.

> One point that gets very little coverage is that fossil fuels are a limited resource Every time someone uses the term “renewable” they are providing coverage to this notion. It is deeply bizarre you can think otherwise.

The renewable in renewable energy sources is referred to, indeed, the energy sources.

The user was arguing that the materials to exploit them are renewable too.

Even the people who understand the scale don't understand the purpose. The Chinese grid isn't renewable or non-renewable. It's built to keep the lights on for anything short of a thousand year catastrophe. Their 2060 plan has enough non intermittent base load that they can run the whole country off it for a decade. That half of your grid capacity is there 'just in case' is something no one in the west can wrap their…

I feel like energy is the most critical aspect to any economy and military. It's the beginning of anything and everything you want to achieve.

It totally is. I don’t remember where I heard it from but there’s a saying that all poverty is energy poverty. Not enough food for your citizens? That’s because you don’t have enough energy to run the Haber Bosch process for fertilizer production.

For a German none of those photos are particularly remarkable or impressive. Especially wind mills - they are all over the place. Outside of cities and forests it would be difficult to not see at least one ... and they like to flock. For example: - https://www.google.com/maps/place/Energiepark+Witznitz+MOVE+... - https://www.erneuerbareenergien.de/energieversorger/stadtwer... - https://www.erneuerbareenergien.de/ener…

> Last year China installed more than half of all wind and solar added globally. In May alone, it added enough renewable energy to power Poland, installing solar panels at a rate of roughly 100 every second.

When did German achieve that?

Fracking. Before fracking people were worried about "peak oil", and being dependent on unfriendly governments for our basic energy needs. Then with fracking we realized we are actually sitting on huge available oil reserves, and peak oil quickly became a quaint outdated concept.

short of the defense of energy infrastructure, of course.
