Types of Energy Sources

Biomass is a renewable source of fuel to produce energy because: waste residues will always exist – in terms of scrap wood, mill residuals and forest resources; and properly managed forests will always have more trees, and we will always have crops and the residual biological matter from those crops.

Chemical energy is that which is either released or absorbed when a chemical reaction takes place, such as the release of heat and electrical energy from a hydrogen fuel cell. Another example is the heat release derived from burning wood or other organic substances.

Generate energy with hydropower dams. All rivers and streams flow downhill across the land surface. Humans can convert this motion of water, which is a form of kinetic energy, into electricity by building dams across rivers. Each dam directs the water flow of the river through a system that generates electricity.

Elastic energy is just potential energy, and you can get potential energy anywhere. If it has to be in the form of a stretch/compress against the object's will type of energy, then you are severely limited to what you can do. Elastic bands and springs are pretty much it, as far as I can imagine.

Geothermal energy is the heat from the Earth. It's clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Geothermal energy comes from deep inside the earth Source: Adapted from a National Energy Education Development Project graphic (public domain) The slow decay of radioactive particles in the earth's core, a process that happens in all rocks, produces geothermal energy. The earth's core is hotter than the sun's surface.

Geothermal power is also considered to be sustainable thanks to its power to sustain the Earth’s intricate ecosystems. By using geothermal sources of energy present generations of humans will not endanger the capability of future generations to use their own resources to the same amount that those energy sources are presently used.

Gravitational energy is the movement of an object or mass that is caused by the pull of gravity. This is caused on Earth by the strong attraction of all other masses to be drawn back to Earth's center.

Hydropower is the most important and widely-used renewable source of energy. Hydropower represents about 17% (International Energy Agency) of total electricity production. China is the largest producer of hydroelectricity, followed by Canada, Brazil, and the United States (Source: Energy Information Administration).

Hydrogen is an energy carrier that can be produced from clean, diverse and abundant domestic energy resources. Fuel cells use the energy from hydrogen in a highly efficient way -- with only water and heat as byproducts.

Hydrogen is considered as a secondary source of energy, commonly referred to as an energy carrier. Energy carriers are used to move, store and deliver energy in a form that can be easily used. Electricity is the most well-known example of an energy carrier.

It is no secret that electric automobiles are here, and they are here to stay. Every major brand you can think of has jumped on this bandwagon because of one reason, they know it is the future.

Energy density of various fuel sources. The amount of energy released in nuclear reactions is astounding. Table 1 shows how long a 100 Watt light bulb could run from using 1 kg of various fuels. The natural uranium undergoes nuclear fission and thus attains very high energy density (energy stored in a unit of mass).

What are Different Sources of Energy? There are 10 main different sources of energy that are used in the world to generate power. While there are other sources being discovered all the time, none of them has reached the stage where they can be used to provide the power to help modern life go.

Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.

Solar power is energy that comes from the sun. Sun is a powerful source of energy. Without it, there would have been no life on the Earth. Solar energy is all about converting the energy from the sun into energy that we can use.

On a much larger scale, solar-thermal power plants employ various techniques to concentrate the sun's energy as a heat source. The heat is then used to boil water to drive a steam turbine that generates electricity in much the same fashion as coal and nuclear power plants, supplying electricity for thousands of people.

· There are government incentives for implementing renewable energy sources, as defined by the U.S. Department of Energy. What clean energy source do you think has the most potential for mass adoption? Share your opinion in the comments.

Because thermal energy is due to the movement of particles, it is a type of kinetic energy, which is the energy due to motion. Thermal energy results in something having an internal temperature, and that temperature can be measured - for example, in degrees Celsius or Fahrenheit on a thermometer.

Tidal energy is a renewable source of energy. During the 20th century, engineers developed ways to use tidal movement to generate electricity in areas where there is a significant tidal range—the difference in area between high tide and low tide.

Ocean wave energy is captured directly from surface waves or from pressure fluctuations below the surface. Waves are caused by the wind blowing over the surface of the ocean. In many areas of the world, the wind blows with enough consistency and force to provide continuous waves along the shoreline.

To stay competitive in this sector, the Energy Department invests in wind research and development projects, both on land and offshore, to advance technology innovations, create job opportunities and boost economic growth.

Wind turbines can be used as stand-alone applications, or they can be connected to a utility power grid or even combined with a photovoltaic (solar cell) system. For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant.
