The disastrous effects of climate change are becoming more and more obvious, making it clear that it is a serious crisis. Serious crises are often needed for humans to change. Think of this: what crisis in your life, such as illness or break-up, did you experience that forced you to change a habit? Had you been thinking of changing this habit before the crisis, but it wasn’t bad enough to change?

For many, the climate crisis is already serious enough to be willing to change. That is why they are inspired to choose more sustainable alternatives and for example look for green energy sources instead of using fossil fuels. Green energy sources are natural, renewable energy sources. Renewable means that the source is being replenished in a relatively short time or even replenished before we could use it all. Common examples are sunlight (further reading: How Solar Energy Technology Is Becoming More Efficient), water, and wind. Less common green energy sources are…
