Showing results for "Energy, Environmental" in Engineering

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.

Solar energy, once a niche application for a limited market, has become the cheapest and fastest-growing power source on earth. What's more, its potential is nearly limitless. But in Taming the Sun, energy expert Varun Sivaram warns that the world is not yet equipped to harness erratic sunshine to meet most of its energy needs. And if solar's current surge peters out, prospects for replacing fossil fuels and averting catastrophic climate change will dim.

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.
