How was energy generated before fossil fuels?
Wood was often used for heating. Wax candle were used for lighting.
Why are nonrenewables also called fossil fuels?
Fossil fuels are those which are naturally created from living organisms, usually only under certain conditions and a very long period of time. The most important ones are coal, oil, and natural gas. They usually consist mostly of hydrocarbons. Nonrenewable fuels are those which are only replenished on a geological timescale or not at all. They include both the above listed fuels as well as uranium, which is not being replenished but at the same time cannot be considered a fossil fuel due to its creation process. In summary: --Fossil fuels have organic origins. --Nonrenewable fuels are not being replaced on any reasonable timescale. They are often confused because of their significant overlap, but are not the same thing.
Is solar cell renewable?
Yes.Completely. No matter how much of the sun's energy we use, the sun will continue to shine just as much as it did before!Solar energy is renewable because, the sun's rays will never run out. That makes it renewable. Renewable energy sources will never run out and we will have a constant supply of them. And with renewable energy sources, we are not hurting the environment as much as when we use fossil fuels. See the link below.Once the sun burns out we will just "renew it" and get another one? Just like oil reserves the sun is a finite amount of energy.Not really, consider the question intelligently and ignore the public hype. A renewable resource at minimum should output more energy than is put into it. It should also not create a significant waste issue. Having worked as an engineer at the largest solar manufacturer on the planet, I can assure you that more energy is required to generate solar cells/pannels than it provides in its lifetime (~20-25 years). The materials used to generate the cells are also considerable and fill landfills. Some of the materials are hazardous and dangerous for the environment. Don't accept answers without substance. I believe in helping the environment but this is not the answer.
Why is this movement often described as horizontal sliding or science?
because Two plates are moving side by side
What is one reason why the fossil record is incomplete?
The fossil record is incomplete because not all fossils have been discovered. In actuality it is unlikely that all fossils will ever be discovered given the hit and miss nature of fossil discovery which usually occurs through educated guess work. The fossil record will likely never be complete.
What energy other than fossil fuels are resources?
Energy resources that are not fossil fuels are often collectively called "renewable resources." These include wind, solar, hydroelectric, geothermal energy sources.
Are all fossil fuels non-renewable?
No. All fossil fuels are non-renewable resources. However, non-renewable resources include more than just fossil fuels. Many minerals are non-renewable including metal minerals (i.e. iron, copper, zinc, lead, gold, silver) and minerals used in agriculture (i.e. potassium, phosphate, sulfur). Products made from gold and silver are often made from recycled gold and silver, but the world supply of these metals is limited.
What is the alternative of the fossil fuel of coal?
Fossil fuels-including coal, natural gas, and oil-are formed from the fossilized remains of prehistoric plants and animals, and fossil fuels provide about 95% of the world's total energy. Alternative fuels are better for the environment and often better for the economy than fossil fuels. Learn about the controversies and conservation plans surrounding fossil fuels, and explore the alternatives.
What is the chemical energy in fossil fuels often converted into?
electrical energy....
The energy in fossil fuels is often converted into?
I think it's electricity.
What is another word for burning of fossil fuel?
Combustion is the term given to burning a fuel, very often fossil fuels.
How is biofuel good?
It reduces the consumption of fossil fuels, and typically burns cleaner than pure petroleum products. Additionally, it is made from renewable resources. However, biofuels also carry disadvantages which often don't outweigh the advantages they possess.
Which 2 fossil fuels of southwest Asia are often found together?
petroleum and natural gas
Which two fossil fuels are often found together in underground rock?
natural gas and oil
Is Styrofoam renewable or non renewable?
Styrofoam is not renewable. It is plastic, made from oil, a fossil fuel. Plastics can be recycled but recycling of domestic styrofoam is often difficult as many recycling plants will not take it.
Is hydrogen renewable?
Hydrogen is renewable in the sense that the fossil fuels we use are hydrocarbon compounds. When we burn them, the hydrogen is liberated in the form of water vapors or hydrogen compounds. These vapors then mix with various gases in the atmosphere to form other compounds like nitric acid, etc. It then comes down with the rain and is deposited on the earth. It thus stays in the system only. Unlike fossil fuels, the hydrogen can be extracted whenever required (fossil fuels need millions of years to produce). Hence hydrogen is considered renewable. At the same time, the energy required to separate hydrogen from the compounds it is a part of often comes from nonrenewable sources, including fossil fuels. Hydrogen does not exist in its elemental state naturally, it is almost always found in compounds like water, so the compound must be broken up by electrolysis or some other means, which requires energy. Research into solar powered electrolysis and hydroelectric powered electrolysis has been done, but it's not yet viable on a large scale. Hydrogen has been produced on a large scale by steam methane reforming. This is not renewable because it involves using methane (a fossil fuel) and getting it to incredibly high temperatures by using more fossil fuels. In some cases around 70% of the gasses produced were not hydrogen but carbon based compounds.
What are the similarities between how oil and coal are used?
They're both fossil fuels, and they're often burned for energy.
