Редактирование: Chapter 7. "Energy and emissions" (раздел)

==The potential of green technology==
<blockquote>From one point of view, it's absurd that there's any risk of greenhouse gas emissions pushing the planet into any danger territory. Instead of making such heavy use of carbon-based fuels, such as oil, gas, and coal, we should be transitioning rapidly to greener, cleaner energy sources. After all, it is frequently remarked that the earth receives from the sun enough energy in a single hour to meet all human needs for energy for a whole year.
