The cost of gasoline varies widely by region. Generally, the cost of gasoline is highest in urban areas and lowest in rural areas. Additionally, the cost of gasoline can vary significantly depending on the season and the type of fuel being purchased.

Greenhouse gas emissions are gases that trap heat in the atmosphere, leading to an increase in global temperatures. These gases include carbon dioxide, methane, nitrous oxide, and fluorinated gases. Reducing greenhouse gas emissions is essential for mitigating the effects of climate change. This can be done through a variety of methods including energy efficiency, renewable energy sources, and carbon capture and storage technology. Additionally, reducing deforestation and improving agricultural practices can also help reduce emissions.

Natural-gas condensate is a low-density mixture of hydrocarbon liquids that are present as gaseous components in the raw natural gas produced from many natural gas fields. It condenses out of the raw gas if the temperature is reduced to below the hydrocarbon dew point temperature of the raw gas. The natural-gas condensate is also referred to as "condensate", or "gas condensate". Depending on the source of gas, its composition, and thus its exact properties, vary widely. But in general it is composed of very light liquid hydrocarbons with an approximate specific gravity ranging between 0.5 and 0.8 and a boiling point between 50°C and 200°C.
