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:
The amount of energy used in a typical household has gradually decreased over the last 5 to 10 years due to increased energy efficiency measures, the adoption of energy-saving technologies such as LED lighting and smart appliances, and a growing awareness of energy conservation practices among consumers. Additionally, the shift towards renewable energy sources has also contributed to reducing the overall energy consumption in households.
Biomass energy produces 3% of the worlds energy
Sound energy is used today in various ways, such as in music and entertainment through speakers and headphones, in ultrasound technology for medical imaging and therapy, and in various industrial applications like ultrasonic cleaning and welding. Additionally, sound energy is utilized in communication systems like telephones and public address systems.
The longevity of an energy source depends on various factors such as the rate of consumption, technological advancements, and exploration of new sources. Non-renewable sources like fossil fuels have finite reserves that are gradually being depleted, while renewable sources like solar and wind energy are essentially inexhaustible when managed sustainably. Overall, a shift towards renewable energy is crucial for long-term sustainability.
A nut typically provides around 5-10 calories of energy, depending on the type of nut. This energy comes from the fats and proteins present in the nut, which are important sources of fuel for the body.

Wind, solar, hydro-electric, biomass and waste to energy plants, wave energy, geothermal and nuclear are a few alternative energy sources among others. All of these have a "net zero" carbon footprint.
The five sources of energy are solar, nuclear, wind, hydroelectric and fossil fuels. Nowadays there are five energy sources: fossil fuels, nuclear, wind, hydroelectric amd solar. The alternative sources are solar, wind and hydroelectric.
Coal, oil, natural gas, uranium, and geothermal. They are used up, and cannot be replaced.
In some cases, or even in most, alternative energy is expensive to produce. Energy such as coal or gas, which can be found in the earth are far less expensive to obtain. Solar heating panels can heat your whole home but few can afford the $5-6000 it would cost.
Coal, oil, natural gas, uranium, and geothermal
Hydroelectric power: Generated by harnessing the energy of falling or flowing water. Biomass energy: Produced from organic materials, such as wood, crop waste, and animal manure. Geothermal energy: Utilizes heat from beneath the Earth's crust to generate power. Solar energy: Captures sunlight using photovoltaic cells or solar thermal systems. Wind energy: Generated by harnessing the kinetic energy of wind using turbines.

A solar panel produces electrical energy with no moving parts. With the Sun facing the panel, 150-200 watts per square metre can be produced by a solar panel. Without direct sunlight a panel still produces power, but very little (e.g. 5-10 watts from a bright sky).
Sweden - with almost all of its energy production being renewable ~50% hydro, 45% nuclear, 5% other (wind, sun etc.). However the industrial and transportion sectors still uses vast amounts of fossil fuel, but machines in factories are often powered by electricity and so is trains, cars and trucks on the other hand are still reliant on gasoline and diesel.
