The energy carried by ocean waves derives from a proportion of the wind energy transferred to the ocean surface by frictional drag. So, ultimately it stems from the proportion of incoming solar energy that drives air movement. Just how much energy is carried by a single wave depends on the wind speed and the area of ocean surface that it crosses; wave height, wavelength, and therefore wave energy, are functions of the distance or fetch over which the wind blows.

Section 8
This unit is taken from Lebensumstände, a language course that concentrates on German as a tool for communication, but it also provides some insights into German society and culture through authentic printed, audio and video materials. It will be of interest to all those who want to improve their language skills in order to communicate more easily and effectively in German. This unit focuses on German family, particularly on the role of parents.

Charting the Course Towards a Low Carbon Economy
The presentation focuses on three key questions on climate change: what set of policies are desirable? What are the impacts of policy action, and is global action achievable? The first question requires the development of a robust national policy framework and to ensure a set of policies are in place that deliver abatement and adjustment at least cost to the economy. The second question requires an understanding of the causes, nature, and the scale of the economic impacts to achieve the transiti
Introduction
This unit provides basic historical background to the French Revolution. It will show that the Revolution accelerated intellectual, cultural and psychological change, and opened up new horizons and possibilities. In fact, while much controversy and scepticism remain as to the real extent of underlying change in the social and economic structure of France, it is generally agreed by scholars that the Revolution stimulated a widening of expectations and imaginative awareness: a belief, inherited fr
Closing thoughts
This unit provides an introduction to global warming. We will be considering the history of global warming by looking at the pattern of ice ages and analyisis of recorded temperatures. We will aim to gather meaningful information from this data. We will briefly assess the impact and influence of humans on global warming and, finally, we will examine climate models and how to predict future changes.
