Electricity plays a fundamental role in our lives, providing a reliable source of power for industrial processes, lighting, cooling, and many other purposes.

Traditionally, fossil fuels such as coal, oil, and natural gas have provided the energy to generate electricity, but now there is an increased focus on the use of renewable sources of energy, such as the wind and sun, to generate electricity.

In this science café we will discuss some of the basics of the electric grid, how it works to dependably bring electricity to your door, and some of the challenges that are created by using renewable sources of energy, instead of fossil fuels, to generate electricity.

Here is an audio recording of this science cafe in mp3 format.
