The Emergence of a “Renewable Feedstock-Based” Chemical Industry
If the future once lay in plastics, as the film “The Graduate” claimed, today the watchword may be “feedstocks.” This term includes corn, wheat, soy, sunflower, rapeseed (canola)—the array of carbohydrates and proteins growing in fields across the planet. The news, as Douglas Cameron makes clear, is that these crops no lon

1.2.2 Present-day energy use
Energy resources are essential for any society, be it one dependent on subsistence farming or an industrialised country. There are many different sources of energy, some well-known such as coal or petroleum, others less so, such as tides or the heat inside the Earth. Is nuclear power a salvation or a nightmare? This unit provides background information to each resource, so that you can assess them for yourself.

Energy from sources other than fossil and nuclear fuels is to a large extent free of the concerns about environmental effects and renewability that characterise those two sources. Each alternative source supplies energy continually, whether or not we use it. This unit considers one of these alternative sources, geothermal energy derived from the interior heat of the Earth, and the potential for this alternative to supplant fossil and nuclear fuel use to power social needs fast enough to avoid t
