Best Answer

Hydroelectric power comes from rivers that are replenished from precipitation. Geothermal energy, though not specifically renewable will not run out within the next few billion years. And biofuels are produced from vegetable matter that can be regrown.

* Geothermal energy is actually partly replenished as a result of gravitational forces from the orbits of the Earth and moon tidally flexing the Earth and producing heat from friction.

Are renewable energy resources also called alternative energy resources?

Yes, renewable energy resources are often referred to as alternative energy resources because they offer alternatives to traditional fossil fuels like coal, oil, and natural gas. These resources include solar, wind, hydroelectric, geothermal, and biomass energy, which are sustainable and have lower environmental impacts.


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.


What are energy resources that can be replaced called?

Energy resources that can be replaced are called renewable energy sources. These include solar, wind, hydroelectric, geothermal, and biomass energy, which are naturally replenished and virtually inexhaustible. Using renewable energy sources can help reduce greenhouse gas emissions and promote sustainable energy practices.


What new energy sources are better for the environment and produce electricity?

New energy resources better for the environment are called renewable or alternate energy forms. They include solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass, biofuel and hydrogen.


Is hydroelectricity a renewable or non- renewable source of energy?

Renewable. Hydropower, also called hydroelectric power, is the technique of harnessing the power of water to create electricity. It is the world's leading source of renewable energy.


Does Hawaii have geothermal energy?

Yes, Hawaii does have geothermal energy resources due to its volcanic activity. Geothermal power plants in Hawaii utilize the heat from underground reservoirs of hot water to generate electricity. This renewable energy source helps decrease the state's reliance on imported fossil fuels.


Energy from hot magma is called?

Geothermal energy. It is harnessed by capturing heat from the Earth's interior and converting it into electricity or for direct heating purposes. Geothermal energy is considered a renewable and sustainable source of power.


An energy source that won't ever run out is called?

An energy source that never runs out would be called: Impossible. There is no such thing as an energy source that will never run out otherwise it would break the Laws of Thermodynamics and we would all be in big trouble. Renewable energy sources are based on things like wind power, solar power which we expect will last longer than the human species.


What is the energy flowing water?

The energy obtained from flowing water is called hydroelectric energy. It is produced by converting the kinetic energy of moving water into electricity using hydroelectric power plants. This renewable energy source is clean and sustainable.


Why is ethanol from sugar cane called biofuel but ethanol from ethene not?

Ethanol from sugar cane is considered a biofuel because it is derived from a renewable plant source, sugar cane. Ethanol from ethene, on the other hand, is produced from non-renewable fossil fuels through a chemical process, making it a traditional fuel rather than a biofuel.


What is power from natural steam called?

Power from natural steam is called geothermal power. This sustainable energy source involves using the heat trapped beneath the Earth's surface to generate electricity through steam turbines. Geothermal power is renewable and environmentally friendly.


What energy from steam under the earth is called?

The energy from steam under the earth is called geothermal energy. This renewable energy source harnesses heat from the Earth's core to generate electricity through steam turbines. Geothermal energy is a clean and sustainable option for power generation.
