Global energy demand has grown steadily since the industrial revolution. During the two decades from 1991 to 2012, total primary energy demand (TPED) grew from 91,200 to 155,400 TWhth, or by 70%, and projections expect this number to increase by a further 40% by 2040. Although greenhouse gas emissions in the energy sector have to be reduced to zero...
This paper presents a comprehensive analysis of the suitability of nuclear power as an option to combat the escalating climate emergency. Summarizing and evaluating key arguments, we elucidate why nuclear power is unsuitable for addressing climate change. The primary argument centers around the unresolved technical and human risks of accidents and...
Diese Studie zeigt wie die kostengünstige und klimaverträgliche Energieversorgung der Region Berlin-Brandenburg in Zukunft aussieht.
Legt man die Lernrate der Enntwicklung der erneuerbaren Energien und Speichertechnologien in den letzten Jahren auch für die kommenden Jahre zu Grunde, können durch eine vollständig erneuerbare Versorgung die

To be able to fulfil the Paris Climate Agreement and keep global warming with reasonable confidence at a maximum of 1.5 °C above pre-industrial levels, Germany must set an end to all greenhouse gas emissions by 2030. At the core of this task is the switch to 100% renewables across all sectors on the same time horizon. Conventional technologies fuel...
It is widely scientifically recognised that a global temperature increase by more than 2°C threatens to lead to a so called Hothouse Earth scenario in which human civilisation as we know it can no longer exist.
While point of no return is near, this possibly extinctive threat is not perceived as such by the political world, the media and to some e...
Natural gas is often presented as a climate-friendly alternative for the electricity and heating sectors and as a "bridging technology" with a key role on the way to a sustainable energy system. If, however, methane emissions are considered in addition to carbon dioxide emissions , it can be seen that a climate protection strategy based on natural...
The state-of-the-art scientific modelling of the “Global Energy System based on 100% Renewable Energy – Power, Heat, Transport and Desalination Sectors” study simulates a transition to 100% renewable energy of the entire world, structured in nine major regions and 145 sub-regions on an hourly resolution of 5-year time periods from 2015 until 2050....
The study showcases that a global 100% renewable energy system can be achieved with zero GHG emissions before 2050 and more cost-effectively than the current fossil fuel and nuclear-based energy system. Solar photovoltaics (PV) and wind energy emerge as the new workhorses of the future global energy system. Solar PV emerges as the most prominent el...
Technical Report "Global Energy System based on 100% Renewable Energy – Power Sector", published at the Global Renewable Energy Solutions Showcase event (GRESS), a side event of the COP23, Bonn, November 8, 2017
A global transition to 100% renewable electricity is feasible at every hour throughout the year and more cost effective than the existing...
Introduction to the Technical Report ”Global Energy System based on 100% Renewable Energy – Power Sector”, published at the Global Renewable Energy Solutions Showcase event (GRESS), a side event of the COP23, Bonn, November 8, 2017
A transition towards a 100% renewable energy (RE) power sector by 2050 is investigated for Ukraine. Simulations using an hourly resolved model define the roles of storage technologies in a least cost system configuration. Results indicate that the levelised cost of electricity will fall from a current level of 82 €/MWhe to 60 €/MWhe in 2050 through...
A transition towards a 100% renewable energy (RE) power sector by 2050 is investigated for Ukraine. Simulations using an hourly resolved model define the roles of storage technologies in a least cost system configuration. Modelling of the power system proceeds from 2015 to 2050 in five-year time steps, and considers current power plant capacities a...

Zero-emission technologies are essential for effective climate protection. Governments must implement legislation to make the necessary investments profitable. The financial world should unite in order to be able to consult and influence governments.
Die Energiepolitik der Welt muss sich von Grund auf ändern. Drei Herausforderungen, von denen unsere Zukunft abhängt, stellen sich uns. Alle drei stehen indirekt im Zusammenhang mit der fossilen und atomaren Energietechnologie.
Significance of renewable energies in the current economic crisis The financial crisis is having a devastating impact on the global economy. Practically all the world's governments are attempting to support their economies with stimulus packages in order to avert high levels of unemployment and the social disruption that would accompany them.
