Which type of fuels are less polluting and why?

Answer: the fuels like CNG, LPG, biofuels are the fuels which are less polluting. Explanation: these fuels are less polluting because carbon content is lesser due to which the threat of increase of carbon in the is reduced and the stress of increase of global warming is also reduced.

Which fuel is less polluting fuel?

CNG
CNG is also credited as being the cleanest burning fuel in the market today. CNG burns cleaner than petroleum based products because of its lower carbon content. It produces the fewest emissions of all other fuels and contains significantly less pollutants than gasoline.

Is kerosene less polluting fuel?

So, it can never be a clean or less polluting fuel. Although kerosene is one of the safest fuels, yet it has a major impact on climate as it absorbs heat and sunlight from the atmosphere and warms the air around.

Which of the following is the least polluting fuel class 8?

Answer: (a) Fossil fuels are Natural Gas, Coal and Petroleum. (b) Process of separation of different constituents from petroleum is called refining. (c) Least polluting fuel for vehicle is CNG.

Which fuel pollutes the most?

Coal produces more pollution than any other energy source. While coal produces just 44\% of U.S. electricity, it accounts for 80\% of power plant carbon emissions. Burning coal leads to soot, smog, acid rain, global warming, and carbon emissions.

Which of the following is the least pollutant?

-As we have got our answer that nature gas is the cleanest fuel means it is least polluting fuel as well, let us now focus on the three other options. 1. Coal is known to be a complicated compound having constituents containing carbon, oxygen, nitrogen and sulphur.

Is CNG more polluting fuel than petrol?

CNG is very cost-effective, eco-friendly, safe to use and causes no health issues. Therefore, it is very less polluting. – Petrol and diesel are highly polluting as it can cause health issues like respiratory problems and it can also cause air pollution.

Which fuel does least harm to the environment?

Natural gas, for example, is most dangerous to the environment in its natural state. The emissions from burning natural gas — a.k.a., methane — does less damage to the environment than allowing it to escape into the atmosphere. Another example of pollution during the extraction state is the mining of coal.

What kind of fuel is best for the environment?

Diesel engines get better fuel economy than gasoline engines. Diesel and diesel engines produce fewer and less toxic emissions than gasoline and gasoline engines. They are safer for the environment.

Which of the following is a least polluting fuel petrol CNG coal diesel?

Natural gas is stored under high pressure as Compressed Natural Gas (CNG). It is considered as a clean fuel as it emits less toxic gases into the atmosphere than other fuels like petrol, diesel and coal upon combustion. Hence, it is now being used as a fuel for vehicles.

Which fuel is more polluting?

CNG is more polluting fuel than petrol.

Which is the most polluting fuel?

Coal, the most polluting fossil fuel, is still the world’s favourite for electricity generation.

Which fuel is least polluting and why?

Electricity, as it can be generated in a sustainable way, and its delivery and transportation has much lower environmental impact than other fuels including petrol. diesel, hydrogen and LPG/CNG. Hydrogen gas is least polluting.

Is hydrogen a non-polluting fuel?

If we are looking at local pollution where the fuel is consumed, hydrogen is almost entirely non-polluting. It burns to form water vapor. But if we are looking globally, the hydrogen gas was manufactured from some other energy source. So the global answer depends upon which energy source was used.

Is petrol more polluting than diesel?

Petrol is less polluting than diesel fuel. But it also depends on the maintenance and quality of the vehicle that uses it. Look here for more: Fact Check: are diesel cars really more polluting than petrol cars?

Why is hydrogen a better fuel than coal?

Hydrogen as a fuel has zero pollutants but making hydrogen uses fuel that has pollutants. Also Hydrogen is the most abundant element on earth. Hydrogen when burned becomes water (H2O = 2 Hydrogen atoms plus one oxygen atom = water) Coal can be an extremely clean fuel if burned correctly and the gases recovered.
