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%

Answer:
The temporal lobes are also believed to play an important role in processing affect/emotions, language, and certain aspects of visual perception.
The cerebellum is busy planning, adjusting and executing movements of the body, the limbs and the eyes.
Explanation:
Oxygen
Plants and photosynthetic algae and bacteria use energy from sunlight to combine carbon dioxide (C02) from the atmosphere with water (H2O) to form carbohydrates. These carbohydrates store energy. Oxygen (O2) is a byproduct that is released into the atmosphere. This process is known as photosynthesis.
