An economic slowdown, renewable energy growth and the impact of Covid-19 have led to the first year-on-year reduction in India’s CO2 emissions in four decades. Emissions fell by around 1% in the fiscal year ending March 2020, as coal consumption fell and oil consumption flatlined.

TADEAS: me ty otazky ale moc nenavadej, asi mam spatnej den. mam nechat rust plevel na poli, abych ziskal mizerny hnojivo pro narocny plodiny? nebo mam sit obili na pastvach, protoze je lepsi ty bobky neprevazet?

fakt nevim :)

SHEFIK: psal jsi, ze to co se zaorava je hnojivo (a to je z pastvy - plevele v tvem zargonu). zaroven je hnojivo npk.tak co to hnojivk teda je? co dela? promin, zeptat se takhle je primejsi nez ti tu davat milion odkazu.

TADEAS: na plevel ti staci minimum, navic mas na podzim listi, vetrem prach, pak mas pudni organismy apod.

ale me slo spis o to pole, kde jde o intenzivni plodiny/hospodarstvi. jak tam bez orby dostanes jinak nez umelym hnojivem naky ziviny/regenerujes pudu, kdyz nebudes zaoravat hnuj?

A jeste nejakej souhrn recenzi

However, as leading environmental activist Bill McKibben answers back, engineers have done their job since in vastly improving this technology, making solar the cheapest way of generating energy today. According to McKibben, since a panel now lasts (up to) three decades—taking four years to compensate for the energy it took to build it—90 percent of the power it then produces is carbon-emissions-free. Moreover, others point out how the overall impacts across the lifecycle (to mine materials, build, transport, install, and uninstall) both solar PVs and wind towers is between 3 and 28 times lower than using, say, liquified natural gas for electricity production (natural gas is one of the less polluting forms of fossil fuels).

Jeste nejaky smirilevejsi nazor na Planet of Humans

"Despite the hullabaloo, the central points in the film aren’t particularly controversial. Corporate-industrial society is driving human civilization/humanity towards the ecological abyss and environmental groups have largely made peace with capitalism."

SHEFIK: a o to prichazi ta pastva-plevel (kdyz to zaoravas)?

TADEAS: N-P-K plus naky mineraly...)

SHEFIK: co je to hnojivo?

TADEAS: na poli to teda vyresim jak? jen tim ze neoram? takze ani nezaoravam zbytky?

pastva si muze o naky to hnojivo dovolit prijit ne? jde o plevel stejne..

realne me to zajma

INK_FLO: fajn, ze se nazor meni. skoda jen, ze ta cesta ven, kterou popisuje je zase vydotovana a tim i limitovana vyhrazenymi penezi, misto toho, aby se nastavily pravidla tak, ze se ty aktivity budou vyplacet (zaoravani humusu apod.). takze misto zaangazovani trhu se na tom namlsa par subjektu na par mistech republiky...

Jeste k Planet of Humans:

Here are some questions that the film raises, and my answers:
Are EVs Just as Polluting as Gasoline Vehicles?
The time-capsule quality of the film is underscored by a scene filmed in Michigan about a decade ago showing an event tied to the rollout of the Chevrolet Volt, a plug-in hybrid vehicle that began production in 2010. The narrator makes the point that the vehicle was powered by a local utility that runs almost completely on coal, as if to say that the environmental benefits of an EV are illusory.
The film is recycling an old argument: that the use of fossil electricity means electric vehicles have about the same emissions as gasoline vehicles. But researchers have looked closely at this and found that there is a clear emissions benefit of using an EV.
For example, the Union of Concerned Scientists has found that EVs have lower emissions—including emissions from generating electricity—than typical gasoline models, even in the parts of the United States that still rely the most heavily on fossil fuels for electric power.
The environmental benefits of EVs will increase as utilities continue to reduce their emissions and as batteries used in the vehicles become more efficient.

Do Solar Panels Only Last 10 Years?
Planet of the Humans shows an unidentified man at a solar trade show who says, "Some solar panels are built to last only 10 years, so it's not as if you get this magic free energy."
I can only guess that this comment is from years ago, when panels were less durable and efficient than they are today. I know of no solar panel on the market today with such a short life span.
