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.

What is a another name for renewable energy source?
alternative energy
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 alternative resource?
Alternative resources refer to renewable sources of energy, such as solar, wind, hydroelectric, and geothermal power, that can be used as an alternative to fossil fuels. These resources are sustainable and have lower environmental impact compared to traditional energy sources.
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.
What is the two reasons why alternative energy sources may be important in the future?
Alternative energy sources may be important in the future because they can help mitigate climate change by reducing greenhouse gas emissions, and they can help diversify energy sources and increase energy security by decreasing reliance on finite fossil fuels.
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 is exhaustible?
Fossil fuels such as coal, oil, and natural gas are exhaustible energy sources because they are finite and will eventually run out.
What energy source can you use instead of fossil fuels?
Fossil fuels are exhaustible. Electric energy is an alternative.
What are the two non exhaustible sources of energy?
The two non-exhaustible sources of energy are solar power and wind power. Solar power is derived from the sun's radiation and wind power is generated by the movement of air masses on Earth. Both sources are renewable, meaning they will not run out over time.
What is a another name for renewable energy source?
alternative energy
What does exhaustible energy mean?
It is energy that won't last forever, or that will run out. An example of this is petroleum, which does form naturally, but only over thousands of years. At the rate at which humans use it, petroleum will most certainly run out before natural processes can replenish it.
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).
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 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.
What will developing alternative energy sources reduce your need for?
Developing alternative energy sources reduce your need for oil and coal, primarily.
Are fossil fuels alternative energy?
No. Alternative energy means energy sources other than fossil fuels.
