Elements of Renewable Energy

Learn how sustainable energy from the Greek elements – Earth, Air, Fire and Water – can replace fossil fuels and nuclear power.

Course Summary

Why to enroll this course?

We've decided to use the four Greek elements as a way of focusing our attention on some key renewable energy sources.

Almost all of our renewable energy sources are derived from the massive power delivered by the sun to the Earth.

We'll introduce the concept of energy, discuss current world energy supply and demand, and look at the prospects of renewable energies being able to supply our demands.

In the second week, under the heading of air, we'll examine wind power, another technology that's been used for thousands of years to power ships and grind corn.

We look at the latest wind turbines, the atmospheric processes that power them, the energy they produce, their economics, and their future prospects on shore and off shore.
