What is a major disadvantage of using fossil fuels?
They warm the planet.They release greenhouse gases.They release Carbon Dioxide back into the atmosphere. They therefore help to cause global warming.They also release poisonous gases such as Carbon Monoxide.They are a non renewable resource that releases long sequestered CO2 (a greenhouse gas) into the atmosphere.
What is happening if energy input remains constant and voltage remains the same in a circuit but the current decreases?
The resistance is decreasing
What are some alternates to fossil fuels?
1.solar energy2.electricity3.fuel cells4. methanol5. ethanol6. biodieselBio-DieselBio-Diesel is a kind of diesel fuel derived from vegetable oil and animal fat. It is an alkyl ester which is obtained by trans-esterification of vegetable oil using ethyl alcohol. It is often used in a blended form along with the normal diesel. So, currently it is mostly used as a diesel fuel additive. This blending of bio-diesel with normal diesel, reduces emission of pollutants. It has excellent lubrication properties. It is being widely introduced all around the world in every form of locomotive.Bio-AlcoholAlcohol derived from plant sources can be used as an effective alternative to fossil fuel. Ethanol, Butanol, Methanol and Propanol are the alcohols of interest which can be used as fuels. These four types of alcohol can be easily derived from biological sources. They have properties which make them useful as fuels in automobile engines. In fact, Butanol is very similar to gasoline and has a comparable energy density! Methanol and ethanol have high octane rates. Ethanol can be produced from sugar fermentation and is indeed widely produced around the world, now as an alternative fuel.HydrogenThe properties of liquid Hydrogen, make it an ideal candidate for use as an alternative to fossil fuel. In normal conditions of temperature and pressure, molecular Hydrogen has a peaceful co-existence with oxygen and does not burn without input of extra energy. Hydrogen fuel cells have been developed which use molecular Hydrogen as an effective form of alternative fuel. The Hydrogen Fuel cell, convert chemical energy contained in a Hydrogen molecule, to electrical energy. The major advantage of Hydrogen as alternative fuel is, that its unit mass contains 2.8 times the energy contained in the same mass of gasoline. Hydrogen powered cars are already a reality but the problem lies in the cost of production. Until that cost is brought down, this technology is not commercially viable.Liquid NitrogenLiquid Nitrogen based cars have been developed using nitrogen powered internal combustion engines. Regenerative braking technology, which stores the impulse generated through braking, uses liquid nitrogen as fuel. A liquid nitrogen car is much like an electric car in its circuitry, except that the batteries are replaced by liquid nitrogen fuel tanks.Vegetable OilDiesel engines have been run on fuel which is a blend of processed vegetable oil and normal diesel. It has been tested as a fuel and is found to be an eco-friendly alternative.These are some of the alternatives to fossil fuels, available currently. The list is short but certainly promising! In the future, more and more such alternatives will be made available, as the new promising technologies like hydrogen fuel cell and hybrid car technology is made more affordable. By promoting the use of these alternatives to fossil fuels, we can make our world a greener and a safer place to live!
Is fuel needed to get geothermal energy?
Geothermal energy, such as hot springs, is used to heat home and factories so in this sense geothermal energy is fuel. However to create a system that uses geothermal needs an infrastucture which needs to be designed and built, in this sense geothermal energy needs an energy input.
A light bulb converts 10 percent of the electrical energy and thermal energy it uses into radiant energymake a hypothesys about the other form of energy produced?
A lightbulb usually won't use thermal energy, only electrical energy. By conservation of energy, if 10% of the electrical energy is converted into radiant energy, the remainder is wasted - basically as heat.
What is the block diagram of fossil fuels input to electricity output?
c.
What is causing globalwarming?
It is caused by the increased input of CO2 or Carbon Dioxide into the atmosphere by human beings through burning fossil fuels for energy. This traps heat which inturn cooks the Earth.
What is the main cause of increased carbon dioxide?
The increase of carbon dioxide in the atmosphere is a combination of increased input from vehicles and industry, and a decreased outtake due to large amounts of trees being cut down and not replaced.
How does energy efficiency affect global warming?
The higher the fossil power plant efficiency the less input fossil fuel burning and hence the less green house gas emissions and accordingly the less global warming.
Energy release is to condensation as energy input is to?
Energy release is to condensation as energy input is to vaporization. Vaporization requires energy input to happen, while condensation releases energy.
What is a major disadvantage of using fossil fuels?
They warm the planet.They release greenhouse gases.They release Carbon Dioxide back into the atmosphere. They therefore help to cause global warming.They also release poisonous gases such as Carbon Monoxide.They are a non renewable resource that releases long sequestered CO2 (a greenhouse gas) into the atmosphere.
Is energy input usually greater than energy output?
The energy input is always greater than energy output.
What is the relationship between energy input and energy output and energy losses whenever transfer of energy takes place?
Input energy = output energy + losses
What are the energy transformations for a jet plane rapidly accelerating on the runway?
Input energy: The jet plane usually uses the chemical energy in some fossil fuel.Output energy: "Accelerating" means that its speed increases; that means that its kinetic energy increases. Energy is also wasted when burning the fuel, as heat; and the plane wastes energy through friction.
What is the movement of molecules the input of energy?
The movement of molecules without the input of energy is passive transport.
What is input energy?
Where the energy enters the system.
What is the input energy for a computer?
Electrical energy
