Preface:

In this seminar we studied the sun as the source of ener-gy on earth; fossil fuels and their liabilities; and renewable energy sources such as photo voltaic (solar cells), eólic (wind) and low head hydroelectric (moving water). We studied the particular application of renewable energy to the tropics (e.g. Puerto Rico), and the importance of energy storage in batteries and super capacitors in the implemen-tation of renewable energy systems. We discussed the technology involved in theses renewable sources, conduct demonstrations, and experiment.
