Energy Resources

 Humans have relied on wood for energy, for burning for cooking and keeping us warm, but most developing countries use wood for burning. 

Most modern countries use lots of coal, oils and natural gasses, daily, in recent years there are now more ways to get large amounts of energy, although they are not as efficient as the un-renewable sort.  

There are hydroelectric, geothermal, solar, wind, and lots of other ways to generate electricity. In most countries, most of the energy resources collected are used for transport and domestic use, such as in homes.

During the Industrial Revolution, coal was used in trains. It was found that burning coal produced energy that could be used to power trains.
Now most trains are powered by electricity since there are many other ways to gather electricity than coal, along with biofuels, which are types of fuels made from plants which are 100% renewable when farmed correctly, and use of electric cars and now hydrogen cars.

Along with natural gasses, which are burnt on stovetops to boil water, we used unrenewable coals last time. 

One thing about electricity is that it isn't 'renewable' or 'non-renewable', as how it is gathered changes how  

Nuclear energy is actually more efficient and better for the planet than burning fossil fuels, even though it is a finite resource, nuclear energy is harder to use because of how rarer it is, along with the fact that it creates radioactive waste which stays radioactive for thousands of years and must be stored carefully.

It is also very expensive to run a nuclear power plant, and the danger of a nuclear meltdown, which can cause environmental damage by releasing harmful radioactive material into the atmosphere.
