  2. Chemical energy - Wikipedia

    en.wikipedia.org/wiki/Chemical_energy

    Chemical energy is the energy of chemical substances that is released when the substances undergo a chemical reaction and transform into other substances. Some examples of storage media of chemical energy include batteries, [1] food, and gasoline (as well as oxygen gas, which is of high chemical energy due to its relatively weak double bond [2] and indispensable for chemical-energy release in ...

    In fact, the loss in thermal plants is due to poor conversion of chemical energy of fuel to electricity by combustion. Chemical energy of fuel is not inherently low-quality; for example, conversion to electricity in fuel cells can theoretically approach 100%. So energy loss in thermal plants is real loss.

    Energeticism, theory that there is no matter and everything is composed of energy; Energy (esotericism), invoked by spiritualists for alternative modes of healing the human body as well as a spirit that permeates all of reality. Orgone, Wilhelm Reich discovered this energy and tried to use it to cure various physical ailments and control the ...

    en.wikipedia.org/wiki/Electrochemistry

    The electrochemical reaction that produced current was (to a useful degree) reversible, allowing electrical energy and chemical energy to be interchanged as needed. Common lead acid batteries contain a mixture of sulfuric acid and water, as well as lead plates. The most common mixture used today is 30% acid.

    The land-use decisions of cities and towns also explain some of the regional differences in energy use. Townhouses are more energy efficient than single-family homes because less heat, for example, is used per person. Similarly, areas with more homes in a compact neighborhood encourage walking, biking and transit, thereby reducing ...

    en.wikipedia.org/wiki/Energy_development

    Energy development is the field of activities focused on obtaining sources of energy from natural resources. [citation needed] These activities include the production of renewable, nuclear, and fossil fuel derived sources of energy, and for the recovery and reuse of energy that would otherwise be wasted.
