By this, do you mean kinds of renewable energy or resources in general? If you mean renewable energy sources, some examples are wind power, solar power, geothermal (uses heat from the ground), or hydroelectric (creates electricity using the power of water). Nuclear energy, although it releases no greenhouse gases and is environmentally friendly, is usually not considered a renewable energy. I don't know why.
If you're talking about actual resources of materials, all will eventually run out, even if not for a billion years. But nearly all won't run out in our lifetimes.
Basically, the renewable fuels are naturally produced biofuels, fuels synthesized using renewable resources, and hydrogen. Some examples of naturally produced biofuels are the following:
- fire wood
- vegetable oils
- animal fats and oils
- ethanol from fermentation of natural products
- methane captured from landfills or sewage treatment plants
Some examples of synthesized fuels that can be made from renewable resources include the following:
- wood gas, which is derived by pyrolizing wood
- charcoal, similarly derived
- gasses similar to wood gas, derived from algae, grass, or other sources
- methane derived by catalysis from wood gas or other sources
- methane derived by catalysis of carbon dioxide and hydrogen by using the Sabatier process
- methanol derived from carbon monoxide in wood gas or other sources by catalysis
- propane, renewable replacement for gasoline, and renewable replacement for diesel oil, derived from renewably synthesized methane by the Mobile process
Hydrogen can be produced in a variety of ways, including electrolysis of water.
The list of actual fuels is endless, and we can replace just about any fossil fuel with a renewable equivalent. Diesel fuel, for example, can be made from wood, at a rate of about one fifth of a liter per kilo of wood, or 120 gallons per cord of firewood. The renewable equivalents are usually superior to fossil fuels, because they do not have the impurities fossil fuels have.
Water, also known as hydropower, makes use of gravitational potential energy from water rushing down the dam and converts it to electrical energy. This method can be used to power many homes in the area, as well as irrigate plots of farmland, operate watermills etc.
Wind, using a wind turbine, can be used to turn it and produce electricity.
Sunlight, or solar power, converts sunlight using photovoltaic cells into electricity. This can be used to power homes, cars, streetlamps and many other appliances.
One renewable fuel is biodiesel, which is made from natural oils and fats. It can be used as a direct substitute for traditional diesel fuel in vehicles.
The other types of renewable resources that might be used to power vehicles are biofuels. These bio fuels are made of corn and soybeans.
Fossil fuels (coal, oil and natural gas) and uranium (nuclear energy) are all non-renewable.

Which is not a renewable energy resources?
Coal is not a renewable energy resource. It is a fossil fuel that is finite and non-renewable, unlike solar, wind, and hydroelectric power which are sustainable and replenishable resources.
Is nuclear power a renewable energy resource?
No, nuclear power is not considered a renewable energy resource. It relies on the fission of uranium or plutonium, which are finite resources. Although nuclear power produces electricity without emitting greenhouse gases, its fuel source is not renewable.
What is wind fuel?
Wind fuel refers to the energy generated from the movement of air, which is harnessed by wind turbines to produce electricity. Wind power is a renewable source of energy that does not produce greenhouse gas emissions, making it a cleaner alternative to fossil fuels.
Is radioactive fuel renewable?
Not exactly, the U-235 content decreases as it is used in the reactor, but also some of the U-238 is changed into plutonium, and if the fuel is chemically processed this Pu can be extracted and used in mixed oxide fuel (MOX). I don't call this renewable however, because ultimately the whole series of processes relies on a new supply of uranium which can only be obtained by new mining sources.
How do you tell the difference between a renewable and a non-renewable source of energy?
Renewable sources of energy can be replenished naturally and are essentially unlimited, such as solar or wind energy. Non-renewable sources, like fossil fuels, are limited and will eventually run out because they cannot be replenished on a human timescale.
What is renewable fuel?
renewable fuel is fuel that can be use again and again
Why is LPG considered a better fuel than coal for cooking purposes?
because coal is a fossil fuel and non-renewable one where as LPG is a renewable one
What is one non renewable fuel?
coal , oil
Is synthetic fuel a non renewable energy source?
synthetic fuel is renewable
Is gasohol renewable?
Gasohol is not a renewable fuel. Gasohol is a mixture of gasoline and alcohol and because gasoline is not a renewable fuel, gasohol is as a whole a nonrenewable fuel.
What are some types of fuel?
First, fuel is anything combustible. So there are two types of fuel: renewable and none-renewable fuel.
Are fuel cells a renewable or non renewable source of energy?
Fuel cells are a manufactured item and are not renewable. The fuel that is used in the fuel cells can either be renewable (alcohol, methane from waste digestion,hydrogen from wind or solar conversion of water) or non-renewable (Hydrogen or methane from oil and gas production, alcohol from industrial processes)
Is anthracite renewable or non-renewable?
Anthracite is a form of coal, which is a fossil fuel, and is thus non-renewable.
What is petroleum fuel classified as?
None renewable or fossil fuel
Are fuel cells renewable?
Yes
Is oil renewable or no?
No. It is a fossil fuel.
What is one disadvantage of oil?
It is non-renewable, and therefore merely a temporary source of fuel and materials.
