Getting Germany to Carbon Neutral by 2050 - a Scenario

Germany 2050 - a greenhouse gas-neutral Country (32 page pdf, the German Federal Environment Agency (UBA), Oct. 2013)

Also discussed here: Germany 2050 - A Greenhouse Gas-Neutral Country (Das Umweltbundesamt Für Mensch und Umwelt)

Today we review a report from the German Environmental Agency (UBA) which describes a scenario for to reduce carbon emissions for that country by 90% before 2050 without any significant change in consumption or an increase in biofuels and dependence on nuclear energy – notable conditions that many other national carbon reduction plans depend on. The prime approach is a switch to renewable energy accompanied by generation of hydrogen from renewable, as a fuel for transportation and industry. Large scale increases of photovoltaic energy generation from solar panels and of wind power from turbines along the sea coasts is envisaged.

Key Quotes:

“The long-term final energy demand in a greenhouse gas-neutral Germany has been estimated to be approx. 466 TWh/a for power generation, 305 TWh/a for heating fuel, 552 TWh/a for motor fuel and 282 TWh/a for renewable inputs in the chemical industry”

 “It is not possible to meet all energy demands with electricity from renewable sources alone. Mainly in the transport sector, and especially in aviation and shipping, electricity cannot always be used directly.”

“With a share of approximately 50 % (199 TWh/a) in the final energy mix of the industry sector, renewably produced methane will be the main energy carrier in 2050, followed by renewable power with a share of approximately 45 %”

ecological agriculture will have expanded to 20 % of the agricultural land.. no biomass will be grown in Germany for the sole purpose of energy use.. these recommendations champion a significant reduction of meat consumption and an increased use of vegetables.”

“No additional expansion of residential and traffic areas is anticipated for 2050. It is assumed that there will be a linear decline in land use from 80 hectares per day in 2007 to 30 hectares per day in 2020XIII, reaching the zero target by 2050”
