Types of Energy
... These are the two main types of energy:
Kinetic: energy in motion
Potential: stored energy
The following forms of energy can be grouped into those two types.
Heat (Thermal Energy): internal motion of molecules. Ex. water boiling,
turning to steam.
Mechanical: energy from motion and moving parts. Ex. ...

Public schemes for energy efficient refurbishment
Public plans for energy efficient refurbishment are put in place by states to encourage building owners to renovate their properties in a way that increases their energy performance. As financing represents the most important obstacle to this type of renovation, the plans favour financial incentives in the form of loans or grants. Various institutions can be involved in the process, such as ministries, banks, firms, or energy services companies (ESCOs).A number of countries have implemented such plans: the United States, France, Belgium, Germany, the United Kingdom, Australia, Estonia, and others.
