Question

Help me please.

Answer 1

1.) Light energy (the electromagnetic radiation of visible light, like colors are a form of light energy), heat energy (energy transfer through kinetic energy that results in what we perceive as heat), mechanical energy (energy created through the power of an object during a certain position or motion- the swinging of a wrecking ball, for example, provides the wrecking ball with enough mechanical energy to break through a wall), electrical energy (energy carried by active electrons within an electrical conductor, like a phone charger), and chemical energy (energy that is released during a chemical reaction, for example, sticking mentos in a bottle of coke creates enough chemical energy to cause the soda to overflow/explode).
2.) Sunlight (solar energy), wood, oxygen, wind, and fresh water.
3.) Petroleum, coal, natural gas (the kind found in the Earth ), and nuclear power.
4.) Fossil fuels (like petroleum, coal, and natural gas-- nonrenewable).
5.) Around 83.5%
Hope this helps!
