Fossil fuels have been playing a crucial part in energy supply for cities, including crude oil, coal, natural gas. These are formed by decayed plants and animals expose to heat and pressure in the Earth's crust for over hundred millions of years. As they are formed by organic substances and it takes a long time for them to form, they are classified as non-renewable energy. On the other hand, another method to provide electricity is by using renewable energy, it is energy that is collected from renewable resources which are naturally replenished on a human timescale, the most commonly known renewable energy are solar power, tidal power, wind power and geothermal heat energy. In my opinion, I agree that fossil fuels cannot take the place of renewable energy. One of the reason is that renewable energy are more substainable than fossil fuels. For long-term developement, as renewable energy will not be used up, it is better for city developement compared to non-renewable ones. Mo...
