It has long been known that to protect people and the environment from both nuclear risks and dangerous levels of climate change, we must phase out the use of nuclear and fossil fuels, and switch to clean energy technology instead. Using Japan as a example, the „Energy Rich Japan“ Project illustrates that the vision of a clean, green, energy-rich future is not only possible, but globally feasible.
Renewable energy technologies using regional or global sources, cou- pled with a reduction in energy use by adopting energy efficient technologies, offer the only safe and proven option open to us for future energy needs. The objective of this study is to show that a region such as Japan is able to supply all of its own energy needs with this option, and to use the report to influence the discussion over the change from fossil and nuclear energy sources to a sus- tainable energy system.
Antwort zur Frage nach PV-Ausbaukorridoren
Deutsche Sonnen- und Windenergie ist konkurrenzlos, Gastbeitrag im Handelsblatt von Hans-Josef Fell
Die Regierungsfraktionen betonen immer wieder – Frau Staatssekretärin Reiche hat es vorhin ausdrücklich getan –, dass sie hinter dem Ausbau der erneuerbaren Energien stünden. Das Europarechtsanpassungsgesetz wäre nun eine gute Gelegenheit, dies auch wirklich unter Beweis zu stellen. Aber anstatt eines großen Wurfes haben Sie die Vorgaben der EU verwässert und eine Vielzahl von Ausnahmeregelungen gestreut. Dies ist wirklich kein Hinter-den-erneuerbaren-Energien-Stehen.
Antwort auf die Frage zur Entwicklung der EEG-Differenzkosten
Im vorliegenden ersten Teil der Studie „Streitkräfte, Fähigkeiten und Technologien im 21. Jahrhundert – Umweltdimensionen von Sicherheit“ befasst sich das Dezernat Zu- kunftsanalyse der Bundeswehr mit der Thematik endlicher Ressourcen und ihren mögli- chen sicherheitspolitischen Implikationen am Beispiel des Überschreitens des globalen Erdölfördermaximums. Der zweite Teil der Studie befasst sich mit den Themen Klima- wandel und Demografie.
Climate change, pollution, and energy insecurity are among the greatest problems of our time. Addressing them requires major changes in our energy infrastructure. Here, we analyze the feasibility of providing worldwide energy for all purposes (electric power, transportation, heating/cooling, etc.) from wind, water, and sunlight (WWS). In Part I, we discuss WWS energy system characteristics, current and future energy demand, availability of WWS resources, numbers of WWS devices, and area and material requirements. In Part II, we address variability, economics, and policy of WWS energy. We estimate that 3,800,000 5 MW wind turbines, 49,000 300 MW concentrated solar plants, 40,000 300 MW solar PV power plants, 1.7 billion 3 kW rooftop PV systems, 5350 100 MW geothermal power plants, 270 new 1300 MW hydroelectric power plants, 720,000 0.75 MW wave devices, and 490,000 1 MW tidal turbines can power a 2030 WWS world that uses electricity and electrolytic hydrogen for all purposes. Such a WWS infrastructure reduces world power demand by 30% and requires only 0.41% and 0.59% more of the world’s land for footprint and spacing, respectively. We suggest producing all new energy with WWS by 2030 and replacing the pre-existing energy by 2050. Barriers to the plan are primarily social and political, not technological or economic. The energy cost in a WWS world should be similar to that today.
This is Part II of two papers evaluating the feasibility of providing all energy for all purposes (electric power, transportation, and heating/cooling), everywhere in the world, from wind, water, and the sun (WWS). In Part I, we described the prominent renewable energy plans that have been proposed and discussed the characteristics of WWS energy systems, the global demand for and availability of WWS energy, quantities and areas required for WWS infrastructure, and supplies of critical materials. Here, we discuss methods of addressing the variability of WWS energy to ensure that power supply reliably matches demand (including interconnecting geographically dispersed resources, using hydroelectricity, using demand-response management, storing electric power on site, over-sizing peak generation capacity and producing hydrogen with the excess, storing electric power in vehicle batteries, and forecasting weather to project energy supplies), the economics of WWS generation and transmission, the economics of WWS use in transportation, and policy measures needed to enhance the viability of a WWS system. We find that the cost of energy in a 100% WWS will be similar to the cost today. We conclude that barriers to a 100% conversion to WWS power worldwide are primarily social and political, not technological or even economic.
Der EU Energiegipfel letzte Woche hat keine Antworten auf die Sicherung der Energieversorgung, auf steigende Energiepreise, auf die Erderwärmung und zunehmende internationale Spannungen durch Ressourcenverknappung gebracht.
Unter der Dominanz der schwarz-gelben deutschen Regierung wurde verpasst, den dringend erforderlichen Transformationsprozess hin zu einer Vollversorgung mit Erneuerbaren Energien unter Ausschöpfung der großen Energieeinsparpotentiale auf den Weg zu bringen.
