Natural gas. Of the three non-renewable fossil fuels (coal, oil and natural gas), natural gas (methane) produces the least carbon dioxide and other pollution.
Geothermal energy is the least used nonrenewable resource to generate electricity. This is because geothermal power plants are location-specific and require specific geological conditions to harness underground heat sources for energy production.
Hydropower is a nonrenewable energy source with relatively low environmental impact compared to other fossil fuel sources. While it comes with challenges such as habitat disruption and altered water flow, it produces minimal greenhouse gas emissions and air pollution during operation.
Anthracite is the highest grade of coal that produces the least pollution and most energy per unit. It is also known as stone coal, or black coal.
Solar power produces the least amount of pollution among alternative renewable resources. It generates electricity using sunlight and does not produce greenhouse gas emissions or air pollutants during operation.
None whatsoever. At least, none that isn't also produced by every other form of energy.
Coal takes millions of years to form. We can't make more of it. Once it's gone it's gone. At least until more forms in a few million more years...
Natural gas generally causes the least pollution when burned compared to other fossil fuels like coal and oil. It produces fewer greenhouse gas emissions and pollutants such as sulfur dioxide and nitrogen oxides. However, renewable energy sources like solar and wind power produce no pollution when generating electricity.
Burning fossil fuels like coal is one of the least efficient ways to generate electricity because it produces a lot of pollution and waste heat, resulting in a low overall efficiency.
Natural gas creates the least amount of air pollution when burned compared to other fossil fuels like coal and oil. It produces lower levels of greenhouse gases, sulfur dioxide, and nitrogen oxides, making it a cleaner alternative for energy production.
Technically the wind is the lest natural resource used.
