How is energy produced?

---> Well their are different types of generators to create energy. Electrical energy is caused by moving electric charges called electrons. In power stations, turbines are turned using energy from sources such as heat from the wind. Energy could also be used from solar energy which could save the ammount of electricity you use by using sunlight.

Effects of the energy source?

---> Some types of ways that perople do to create energy is made using fossil fuels (coal, oil, and natural gas) and they do substantially more harm than renewable energy sources by most measures.

Advantages and Disadvantages?

---> An advantage of using all these fossil fuels (coal, oil, and natural gas) is that we can get energy faster without hardly any work. The disadvantage of this is that its not good for the earths atmosphere and it harms the planet raising climate change.
