Currently, the most widely used fuels are oil, coal and natural gas. All three come from fossils that take millions of years to process and their combustion produces CO2 gas which is the main cause of climate change. In addition, this fossil fuel is also a non-renewable energy which will eventually be used up.
Conversely, renewable energy is usually abundant and will not be used up. Some examples are sunlight and geothermal energy which are known as alternative energy to generate electricity.

Every day, the earth gets abundant sunlight and can be used as a renewable energy. First, energy from sunlight is collected using a device called a solar panel. Inside there are solar cells that will convert solar energy into electrical energy.
Apart from solar energy, geothermal is also a solution for renewable energy. The core of the earth, which is 3000 kilometers in the interior of the earth, has a temperature that can reach 6000 degrees Celsius. This high temperature is used to become a new source of electrical energy, thanks to technological advances and super-sophisticated equipment by making geothermal wells.
