A few thoughts on the @JoeBiden Victory:
Biden has announced to rejoin the Paris Climate Convention as soon as possible. To do so, USA must present a new ambitious climate contribution for the year 2030, NDC . It will not be too ambitious but everything is better than now (1/7)
The chances to reach 1.5 degree target are increasing. EU, China, Japan others, committed to become climate-neutral in a few decades with strong emission cuts. This is why now in the Corona crisis - unlike in the past - economic aid is increasingly linked to climate aspects (2/7)
If US climate "Green Deal" becomes reality, EU will no longer be a pioneer. The EU need to raise climate targets, expand renewable energies more quickly and immediately abolish any climate-damaging subsidies. The EU should initiate a joint #GreenNewDeal Deal with the USA. (3/7)
Biden also considers Nordstream II (rightly) a mistake. It is unlikely that the sanctions will be withdrawn, but presumably they will not be turned to ever higher levels. Biden supports renewable energy not as much as before artificial support for the gas fracking industry. (4/7)
Nuclear, CCS, fracking will have no future in midterm. All of these technologies are much more expensive than renewable energies. Conventional energy business models have no future. Biden focuses on realism and economy without artificial subsidies for expensive technology. (5/7)
At the same time, renewable energies are becoming ever cheaper, as are energy storage facilities. As a result, they are increasing. Conventional energy subsidies need to be more abolished.
Now is the big chance to agree upon a USA-EU Green Deal for 100% RES. (6/7) #EUGreenDeal
And one final thought as a scientist: It is a nightmare that alternative or fake facts count more than scientific facts. We scientists must do everything we can to better communicate the real scientific facts. This is a huge opportunity, but it is fragile. Now is the time to act.
Zum Thema #Wasserstoff für #Mobilität: Brennstoffzellen-Fahrzeuge haben ein paar Vorteile (Wenig Emissionen, längere Reichweite) sind aber ineffizient, da geringer Wirkungsgrad: bis zu sieben mal soviel Strom zur Herstellung notwendig. (1/5)
#Wasserstoff muss erst erzeugt werden, Infrastruktur fehlt. Mehrere neue Infrastrukturen aufzubauen ist ineffizient und teuer. Dieser "kostbare" Treibstoff sollte nicht verschwendet werden, einzusetzen wo es keine elektrische Alternativen gibt (Schwerlast/Schiff/Flugverkehr) 2/5
"Electricity First": Kleine und leichte Elektrofahrzeuge sind effizient und - wenn sie Ökostrom "tanken"- allen andern überlegen. Wasserstoff oder PtG sind mögliche Langfristspeicher,als "kostbarer" Treibstoff aber nur dort einzusetzen wo es keine elektrische Alternative gibt 3/5
