Read to Learn!
Sustainable energy can be defined broadly as the sustainable
provision of energy that meets the needs of the present
without compromising the ability of future generations to
meet their needs. Moreover, it is the capacity of energy
sources/capital stock to be replenished within human
lifetime, with no long term or irreversible damage to the
environment and renewable energy sources, plus avoidance
or minimisation of waste.
The importance of sustainable energy is related to three elements: the efficient supply of energy
that is a basic condition for economic development; the need to avoid ecological disasters and
reduce or eliminate environmental damage; and the need for equity in the energy sector, which
can be translated into universal access to energy (see SDGs). Sustainable energy emphasizes
energy efficiency and use of renewable sources.
