Energy Consumption
Indirect Energy Consumption
How indirect energy consumption is associated with the
- Production of consumer goods
-> Energy is required to find the materials, get the materials, refine the materials, make the goods and ship them to you - Energy required to build homes
-> Energy is required to find the materials, get the materials, refine the materials, ship them to the site and build the house - Energy for transporting goods
-> Energy is required to find the materials, get the materials, refine the materials to make the transport vehicle and also the fuel for the vehicle, and then drive the goods - Energy requires for the production of food
-> Energy is required to prepare the ground, plant the seeds, harvest the crops, ship them to the food packaging place, and package and ship the food

- Lighting
- Heating
- Fuel for transport

A fossil fuel is a substance made of compressed dead organic matter that is extracted from the ground for use of fuel
Carbon capture describes the process of carbon being absorbed by trees and oceans which stops its from being released into the atmosphere
The greenhouse effect is the process that warms the Earth from sunlight hitting it. It occurs when sunlight hits the Earth gets converted in infrared radiation and is reflected back to the atmosphere. It is then trapped by CO2 in the atmosphere and can be reflected back into the Earth. The radiation heats up the atmosphere and causes the climate to heat up.
A process use to seperate a mixture of liquids based on their boiling points

Saturaed - Has the maximum amount of hydrogens possible
Unsaturated - Doesn't have the maximum number of hydrogens in it
Volatility - How easily a substances changes to a gas
Flammability - How easily a substances combusts
Viscosity - How thick and runny a liquid is
