课程名称：可再生能源——它是什么，我们需要它吗？ 课程概述：我们被敦促更多地利用可再生能源，并投资于家庭和企业的可再生能源未来。但可再生能源究竟是什么？我们需要它吗？如果需要，为什么？哪些技术属于可再生能源，它们的特点是什么？本课程将回答这些问题，以及其他有关可再生能源的疑问，例如：我们真的无法依靠可再生能源保持电力供应吗？为什么某些国家应该以可再生能源为基础建设经济，而其他国家却是以化石燃料为基础？如果可再生能源如此优秀，是什么阻碍我们增加其生产？ 目前我们对化石燃料的依赖是不可持续的。我们正在耗尽这些资源，它们造成了我们所经历的大部分空气、水和土壤污染。在人类历史的大部分时期，我们的生活是由可再生能源驱动的，现在是时候回归这些清洁、现代化的能源来源了。 本课程采用视频讲解、动画和屏幕展示相结合的方式进行呈现，使用适当的选定图像和案例研究来阐明观点。课程首先解释并定义可再生能源，然后探讨向可再生能源未来转型的原因。我们将考察哪些技术是可再生的以及增加可再生能源使用的一些障碍。课程还会考虑核能、氢能和能源效率措施在可再生能源未来中的作用。 课程最后将总结内容并发出行动号召，随后还有一个小测验来确认所学知识，并提供可下载的资源文件。
We're all being urged to make more use of renewable energy and to invest in a renewable energy future for our homes and businesses. But what is renewable energy? Do we need it and if so, why? Which technologies are renewable and what makes them so? This course will answer these questions and others, such as:Is it true we can't rely on renewable energy to keep the lights on?Why should some countries be expected to build their economies on renewables, when others built theirs on fossil fuels?And, if renewable energy is such a good idea, what's stopping us from producing more?Our current reliance on fossil fuels is unsustainable. We are using them up and they cause much of the air, water and ground pollution we experience. For much of human history we've powered our lives with renewable energy and now is the time to return to clean, modern versions of these sources.The course is presented using a blend of talking head, animation and on-screen presentation. We use appropriate, selected images and case studies to illustrate the points. The course begins by explaining and defining renewable energy, before looking at the reasons why we're moving to a renewable energy future. We examine which technologies are renewable and some of the barriers to increasing our use of renewable energy. We also consider the role of nuclear energy, hydrogen power and energy efficiency measures in the context of a renewable energy future.The course concludes with a summary and call to action, followed by a quiz to confirm the knowledge acquired. A resources document can be downloaded.
