In this module, we look at how energy is produced today. We start by understanding what we mean by 鈥渇ossil fuels鈥�, and where they come from. We then turn our attention to how we get electricity by burning them in a power plant. We鈥檒l go into how a power plant works, so you can understand what the coal or natural gas is actually doing in the process of producing electricity. We then examine the relationship between how electricity is produced and the quantity of greenhouse gases that are created. This will be a useful thing to know as we evaluate our own energy usage, and therefore our own contributions to greenhouse gases. Any discussion of energy needs to include nuclear energy. Today this remains is a highly controversial issue, as there are many pros and cons to nuclear power plants. We鈥檒l go over a few of those so you can make up your own mind if nuclear energy needs to be in the mix for the future. Finally, we end on a bright note illustrating that many positive changes are taking place when it comes to transitioning to net zero power generation technologies - technologies that are inherently more environmentally friendly and even less expensive than the traditional fossil fuel technologies used today.
