We all use energy—to travel to school, charge electronics, turn on lights, and even to fill a cup with water. Where does this energy come from? Energy sources fall into two categories: non-renewable and renewable.
Non-renewable energy sources
Renewable energy sources
Non-renewable energy comes from sources that cannot be renewed over a short period of time. For example, all the petroleum we use today was formed hundreds of millions of years ago. Any petroleum we might try to make today would not be ready for millions of years. Non-renewable energy sources such as coal, oil, and natural gas generate harmful pollution and contribute to climate change when they are burned.
Renewable energy, in contrast, comes from sources that are replenished in a short period of time. In some places, the sunshine provides usable solar energy on most days. In other regions, the wind blows regularly, making it possible to reliably generate energy from the wind. Finally, in some locations, rivers flow continuously to produce hydro energy. When renewable energy sources are used, they produce very little to no pollution or greenhouse gasses.
In this experiment, you will examine how a light bulb converts electrical energy to light energy. Light bulbs are usually sold according to the amount of electrical power they consume. You will investigate the relationship between the power rating of a light bulb and the amount of light it produces.
