All over the world governments, organisations, businesses and scientists are looking for new ways to produce and save energy. Almost everything we use today requires energy. Our computers, televisions, microwaves, fridges and lights all obviously use electricity. But did you know that even fruits and vegetables use energy? When farmers use fuel to drive tractors that plough the fields, for example, it means that even uncooked food has already used energy during production by the time it reaches you.
Our main sources of energy are fuel and fossil-based (like oil, coal and natural gas), which are converted to electricity. The challenge unfortunately is that fuel and fossil-based energy will not last forever. In addition to being limited, turning fuel and fossil-based energy sources into electricity releases around 30 per cent of greenhouse gases into the atmosphere, which cause global warming. So the energy we rely on will not only run out someday but is harming our climate in the process.
Fortunately for us there are solutions. We can switch to sustainable energy. This is a form of energy that does not run out and is friendly to our environment. Examples are solar energy, wind energy, hydropower, geothermal energy, bioenergy and ocean energy. The main benefits of sustainable energy are the following:
We also need to use our energy well so that we are not wasting or consuming too much of it, an action known as energy efficiency. Some examples of energy efficiency are when we share vehicles through using public transport, saving power by changing to energy efficient light bulbs and appliances, and insulating water heaters so that they stay warm longer without much electricity used.
You have the power to help the world switch to sustainable energy.
