Renewable Energy

In this course you will learn about the main renewable energy sources. You will also learn about the advantages and disadvantages of various renewable energy sources.  

Introduction

Geothermal energy uses the heat from rocks in the earth’s inner core that turns water into steam.

Engineers drill down into the hot regions and the purified steam rises to drive turbines that produce electricity. Where there is no natural groundwater, cold water can be pumped down to create steam.

As well as being used to produce electricity, the heat from below the ground can be used to directly heat homes and businesses, making it doubly useful.

You will learn 

1. Understand key facts about the main renewable energy sources
2. Explain the advantages and disadvantages of various renewable energy sources
3. Explain the process of power generation by wind, solar, hydro and geothermal sources
