Musta hiili & Climate and Clean Air Coalition

Nyt presidentitkin alkaneet puhumaan mustasta hiilesta (black garbon). Hiili onkin mustaa (sic). Näyttää siltä, että tavanomaiset ilmaukset kuten noki (soot) eivät kelpaa. Musta hiili ei ollut mukana Kioton sopimuksessa, mutta se nousi viisi vuotta sitten isompaan keskusteluun seuraavasti:

Pollutants that are short-lived in the atmosphere such as methane, black carbon and hydrofluorocarbons (HFCs) together account for approximately one-third of current global warming, have significant impacts on public health, the environment, and world food productivity. Secretary of State Hillary RODHAM CLINTON 16 Feb 2012 announced the Climate and Clean Air Coalition (CCAC) to reduce short-lived climate pollutants, a new global initiative to seize the opportunity of realizing concrete benefits on climate, health, food and energy resulting from reducing short-lived climate pollutants. The coalition will focus efforts on reducing black carbon (soot), hydrofluorocarbons (HFCs), and methane. The founding coalition partners are Bangladesh, Canada, Ghana, Mexico, Sweden, and the United States, together with the UN Environment Programme (UNEP).
Tästä kirjoitin 01 Jul 2012 Clintonin USAn suurlähetystössä pitämän esitelmän jälkeen.
Koalitioon on sittemmin liittynyt yli 30 valtiota Suomi mukaan lukien. CCACn pääkonttori sijaitsee Pariisissa.

Note: In addition to carbon dioxide (Global Warming Potential - GWP = 1), the other five greenhouse gases, methane (IPCC AR4 2007: GWP = 25 over 100 years), nitrous oxides (298), hydrofluorocarbons (14,800), perfluorocarbons (1,430) and sulphur hexa-fluoride (22,800) may be converted to the equivalent CO2.

139 maassa 100% uusiutuvaa 2050 mennessä?

By the year 2050, a total of 139 countries could get their energy only from renewable sources such as water, wind and sun.

Researchers at the Stanford University say this would reduce energy consumption, since renewables are more efficient than fossil fuels, but also help create 24 million jobs, and reduce air pollution deaths by up to seven million per year.

Researchers from the university also assert that the conversion to all green energy will spare more than $20 trillion in health and climate costs every year.  [emp]

100% uusiutuvaa - irti sähköverkosta

Ameren Corporation and S&C Electric Company announced that they had successfully conducted a 24-hour islanding test at the recently deployed Ameren microgrid in Champaign, Illinois. The test focused specifically on the 50-kW microgrid at the site, which powers an Ameren research facility. The complete microgrid includes 225 kW of renewable generation (PV solar and wind) and 250 kW / 500 kWh of battery energy storage.

The test began at 8 a.m. on Aug. 3, 2017, with the battery’s state of charge at 97 percent capacity. Once the battery was depleted to 90 percent capacity, solar and wind generation kicked in, simultaneously carrying the load and charging the battery. This pattern continued throughout the day, never letting the battery fall lower than 88 percent capacity. The microgrid functioned without any human interaction, automatically coordinating resources and ensuring power never faltered, according to the company.

“We have one of the few microgrids in the world that operates at utility-scale voltages and can seamlessly transition from grid-connected to islanded mode.”  [rew]

Köpenhamina hiilineutraaliksi

How does a major European capital wean itself from fossil fuels and reinvent itself as a sustainable city? Having already cut its CO2 emissions by 38% since 2005, Copenhagen is in the process of finding out.
The 2025 Climate Plan focuses on energy efficiency, renewable energy production, green mobility, and exemplary use of energy by city government. Setting carbon-reduction goals for each area, the plan then shows, area by area and project by project, how the activities will reduce CO2.  [rew]

Lomborg - Sceptical Environmentalist

Tänään oli Hesarissa Bjorn LOMBORGin kirjoitus otsikolla" Pariisin sopimus ei korjaa ilmasto-ongelmaa". Lomborg tuli tunnetuksi 2001 teoksellaan The Skeptical Environmentalist, joka aiheutti globaalin keskustelun ja tiedemaailman nokkamiesten tuomion. Lomborg tunnustaa maapallon man-made lämpenemisen, mutta hänen mielestään sovitut toimet ovat tehottomia ja tulevat kalliiksi.
Paljon kiistämätöntä faktaa sanomisessaan.

St1 Anttonen kulkee omia teitään

Tämänpäiväisessä Hesarissa oli juttu suomalaisesta tee-se-itse miehestä Juha ANTTONEN, joka on parissakymmenessä vuodessa tehnyt miljardin euron tuloksen. Hän ei usko Pariisin ilmastosopimuksen onnistumiseen ja on erittäin kriittinen Suomen toimintaan uusiutuvien energialähteiden tukemisessa. Anttonen on puhunut aiheesta pitkään; katso hänen hyvä raporttinsa http://energiatyhmyrit.real.fi/2016/06/st-anttonen-kovaa-kritiikkia.html.
Anttonen kulkee omia teitään eikä antanut Hesarille haastattelua.

Sinan the Architect

Muutama viikko sitten kirjoitin betonin historiasta Vitruvius vs Sinan http://energiatyhmyrit.real.fi/2017/06/betonin-historiasta-vitruvius-vs-sinan.html. Vitruviuksen kirjat arkkitehtuurista minulla ovat olleet jo pitkään. Mutta nyt sain hankittua teoksen Sinan's Autobiographies - Five Sixteenth-Century Texts. Tässä 640-sivuisessa kirjassa on 140 sivua pääasiassa englanninkielistä tekstiä, loput nykyturkkia ja Sinanin alkuperäisiä tekstejä arabialaisin kirjaimin.
Pyrin löytämään kirjasta betoniin liittyvää infoa.

Iso vesivoimalaitos Nigeriaan

Decades of planning are coming to fruition as construction of Nigeria's 3,050 MW Mambilla hydroelectric plant began earlier this week. The facility, to-be located on the Donga River in the eastern Taraba State, has stalled repeatedly since its conception in the early 1980s for a number of reasons -- most recently due to a landslide that blocked access routes to the project site in September. Nigeria's Minister of Power, Babatunde Fashola, said earlier this week that the government expects the plant to be complete in 2024.

At that time, Mambilla's cost was estimated at US$6 billion -- 70% of which was reported to be paid by Chinese firms and the remainder by the government of Nigeria. China's interest in the project results from a May 2007 decision to award contracts for Mambilla's development to the China Gezhouba Group Co. Ltd. and Sinohydro.  [rew]

Maailman suurimman vesivoimalaitoksen eli Kiinan Three Gorges Damin teho on 22,500 MW. Suomen suurimman vesivoimalaitoksen Imatran teho on 192 MW, eli 6% Mambillasta.

Kiinaan suuri sähköakkuvarasto

China set to put 120 GWh of battery capacity into the market by 2021. Tämä on puolitoista kertaa Suomen vuotuinen sähkönkulutus!
By comparison, when completed in 2018, Tesla Inc.’s Gigafactory will crank out up to 35 GWh of battery cells annually.  [rew]

Saksa: 35% sähköstä uusiutuvaa

Germany’s electricity from renewable sources accounted for 35% in the first half of 2017, or an increase of 6% compared with the same period last year, according to the BEE renewable energy association.

Germany is planning on eliminating its nuclear power plants by 2022. Germany’s renewable energy has been on the rise for the last two decades due to the Renewable Energy Act (EEG). Around 85 percent of the power from renewable energy was obtained by the nation on certain sunny and windy days.  [emp]
