Clean water, paved roads, public transit, electricity and gas, sewers, waste processing, telecommunication, even the Internet—all this infrastructure is what makes cities work and powers our lives, often seamlessly and silently. Virtually everything we do and consume depends on infrastructure. Yet, most people have no idea how these systems work. How is water treated? How do cities manage rainwater? Why do traffic jams exist? How is electricity generated and distributed? What happens to trash after it is picked up? How does the Internet work?

The near-meltdown of Fukushima, the upheavals in the Middle East, the BP oil rig explosion, and the looming reality of global warming have reminded the president and all U.S. citizens that nothing has more impact on our lives than the supply of and demand for energy. Its procurement dominates our economy and foreign policy more than any other factor. But the "energy question" is more confusing, contentious, and complicated than ever before.

The promise of green jobs and a clean energy future has roused the masses. But as Robert Bryce makes clear in this provocative book, that vision needs a major re-vision. We cannotand will notquit using carbon-based fuels at any time in the near future for a simple reason: they provide the horsepower that we crave. The hard reality is that oil, coal, and natural gas are here to stay.

The clean energy transition is humanity's biggest ever economic challenge. In Powering Up, former Australian chief scientist Alan Finkel shows how to remove the barriers that prevent nations transforming from petrostate to electrostate. Finkel considers the entire supply chain, from raw materials through power infrastructure, the workforce, transportation and household customers. He reveals the outlines of a new geo-economic order and explains in persuasive, practical terms how we can get there.

Die Nutzung fossiler Energieträger wie Kohle und Öl verschärft den Klimawandel, und wir müssen sie so schnell wie möglich ersetzen. Nur, was sind gute Alternativen? Und schaffen erneuerbare Energien es, unseren Energiehunger in Zukunft zu stillen? Sind sie so verlässlich wie die alten Energielieferanten? In diesem gemeinsam mit Studierenden gestalteten Hörbuch untersuchen die Autoren kurz, anschaulich und verständlich, was erneuerbare Energien aus Sonne, Wasser oder Erdwärme energietechnisch schaffen und wie sie sich im Vergleich untereinander bewerten lassen.
