Well, if you want to be pedantic about it, so is solar, wind and tide energy. The sun will transition to red giant in a few billion years then (probably) become a white dwarf. No more sunlight. And even longer after that, as the universe is expanding, due to the law of entropy, everything will eventually be spread out thinly across space, and the energy levels will be constant everywhere. So if you want to be pedantic, EVERY source of alternative energy will run out eventually, but the person asking this question obviously wants to know what alternative energy sources are exhaustible in the timeframe of human existence, and the answer to that is biomass and nuclear (with the current technologies, the figures show we will run out of uranium in about 160-200+ years, but potential new technologies look to be able to extend our uranium supply almost indefinitely). And technically we can run out of (useable) biomass.
Realistically, we're never going to run out of biomass, though producing enough to satisfy fuel demands could be very difficult. Efficient use of current technology and (more important) fuel recycling means that we're unlikely to run out of nuclear fission fuel, either. We're never going to run out of nuclear fusion fuel.
Geothermal is tricky. We're never going to run out of geothermal energy to tap into (as that would require cooling of the earth's core, which won't happen on a human timescale), but individual places where geothermal energy is available can easily change, and as geothermal isn't portable, it is entirely possible for a given location to be unable to produce geothermal power at some point.

Energy sources other than fossil fuel are called what kind of resources?
They are called renewables. (though strictly, nuclear power is not a fossil fuel and is not renewable).They are called alternative energy sources.
What is the two reasons why alternative energy sources may be important in the future?
· To protect against harmful by-products of major sources of energy · To preserve many of the natural resources that we currently use as sources of energy
What are some good sources of Alternative Energy?
Other than what? Please clarify.Common energy sources (for technological purposes) are fossil fuels (petroleum and coal), nuclear energy, as well as solar energy, wind energy, hydraulic (water) energy, and many others.
Which alternative energy sources are not affected by the sun?
Geothermal Hydroelectric PowerCoalWindHope this helps!
What is a direct concern stemming from rising global temperatures?
increased use of alternative energy sources. -- A+
What are exhaustable sources?
Exhaustible sources are natural resources that can be depleted over time, such as fossil fuels (oil, coal, natural gas) and minerals. These sources are finite and not easily replenished at the rate they are consumed, leading to potential scarcity and environmental impacts when exhausted. It is important to find alternative, sustainable sources of energy to reduce reliance on exhaustible sources.
What energy source can you use instead of fossil fuels?
Fossil fuels are exhaustible. Electric energy is an alternative.
What are the differences between conventional and non conventional sources of energy?
Conventional sources of energy have been in use for a long time that usually cause pollution and are exhaustible. Non-conventional sources, meanwhile, are recent sources of energy that are inexhaustible and pollution-free.
Is coal an alternative energy source?
No, coal is not an alternative energy source. "Alternative" energy sources means energy sources other than fossil fuels (coal, oil, and natural gas).
What is alternative sources of energy?
an alternative to electric like solar power
Which alternative energy source is found in Iceland?
The majority of alternative energy sources were put in place by Mannvit Engineering. Currently the most common sources of alternative energy in Iceland are geothermal energy and hydroelectric energy. Mannvit is still exploring other alternative energy sources to be implemented throughout Iceland and the rest of the world.
Is atomic energy renewable?
No. It is an alternative to fossil fuels and is not exhaustible in real terms. It offers the best reduction in CO2 of anything out there, but is not a renewable.
What will developing alternative energy sources reduce your need for?
Developing alternative energy sources reduce your need for oil and coal, primarily.
5 energy sources used as alternative?
The answer depends on how to define alternative energy sources.Alternative energy sources may be typically and interchangeably for renewable energy sources.If this is the case then the five energy sources used as alternative are:Solar,Wind,Biomass,wave, andTidal alternate energy sourcesAlternative energy sources may be defined as sources of usable energy intended to replace fuel sources without undesired consequences of replaced fuels Typically excluding fossil fuels and nuclear energy). If this is the case then the five energy sources used as alternative are:Coal as alternative to wood,Petroleum as alternative to whale oil,Alcohol as alternative to fossil fuel,Coal gasification as alternative to expensive petroleum, andRenewable energy as alternative to nonrenewable energy.For more details it may be referred to:http:/en.wikipedia.org/wiki/Alternative_energy
What do you call renewable safe sources of energy?
Alternative energiesBio energiesSolar energies
Are fossil fuels alternative energy?
No. Alternative energy means energy sources other than fossil fuels.
What does alternative energy resource mean?
Alternative resource is the new renewable or inexhaustable energy source;includes solar energy, wind, and geothermal energy.
