Energy is deposited in a range of
energy sources, which can be non-renewable or renewable. Renewable sources of
energy are those that can be refilled in a short period of time, as opposed to
non-renewable sources of energy.The use of renewable sources of energy is less
polluting, compared to that of non-renewable sources. Specifically, increased
dependence on renewable sources of energy is a key element of efforts to avert
climate change. Renewable sources of energy today make an irrelevant
contribution to total energy use, compared to that of non-renewable sources. A
range of barriers hamper the widespread deployment of renewable energy
technologies.
