John Shanahan, President of Environmentalists for Nuclear - USA: This is a summary of articles about wind and solar technologies without discussion of subsidies posted on this website. It includes comparisons with fossil fuels and nuclear.
Daniel Wetzel, Die Welt: Im ersten globalen Energiewende-Ranking kommt Deutschland nicht mal in Europa unter die Top Ten der Klima-Schützer. Nur gemeinsam mit Frankreich könne Deutschland auf Ökostrom umstellen. Energiewende und Klimaschutz gehören nicht zu den Prioritäten der Regierung. Erreichbar sind ihre 2030er-Klimaziele nur, wenn wir sofort gezwungen werden, jeden Kessel, Ofen, Motor stillzulegen. Völlig illusorisch.
David MacKay, Professor of Physics, University of Cambridge: How can we power a modern lifestyle without fossil fuels? Individual actions saving 10% here and 40% there will not get us off fossil fuels. To eliminate fossil fuel use, we will surely also need to increase the amount of energy we get from non-fossil-fuel sources. Even if we imagine strong efficiency measures and smart technology switches, halving our energy consumption from 125 kWh per day per person to 60 kWh per day, we should not kid ourselves about the scale of the energy challenge which would remain. If Britain and the United States were to "get off" fossil fuels, what would the effect be on Earth's climate? Most of the rest of the world can not afford to "get off" fossil fuels or do not have the right governments, economies, education systems, industrial capacity to do so.
Vijay Jayaraj, Research associate, Cornwall Alliance for the Stewardship of Creation: Climate data from the past contradict the alarmist’s claims that carbon dioxide emissions from human activity have been the primary drivers of global temperatures. Data show that the current warming is not unprecedented but was matched by the Roman Warm Period (roughly 250–400) and Medieval Warm Period (roughly 950–1250). The alarmists’ attitude towards climate change will prove more harmful than beneficial in the long run. Insofar as they prevail, we will become more and more unprepared to face any climatic condition that is contrary to their dubious theories of unprecedented warming.
