Question

Which odorless, colorless, and tasteless resource is considered cleaner than other fossil fuels?

Answer 1

Answer:

The odorless, colorless, and tasteless resource that is considered cleaner than other fossil fuels is natural gas.

Explanation:

Natural gas is usually almost all methane gas, which is a significant fossil fuel for home heating and power generation. Natural gas has been created over time as biomass decomposes in the bedrock through the interaction of anaerobic bacterial activity and soil heat. In addition to methane, natural gas contains small amounts of ethane, propane, butane, pentane and other heavier hydrocarbons, and sometimes nitrogen and helium.

Natural gas is processed before industrial use in a natural gas processing plant where all compounds other than methane are removed. Refining of natural gas is much simpler than refining of oil. Refined natural gas is a colorless and odorless gas with a high calorific value. Methane's carbon dioxide emissions are lower than those of oil or coal.

Answer 2

Natural gasses like methane for example.
