Sunlight and wind, for example, are such sources that are constantly being replenished.
Renewable energy resources exist over wide geographical areas, in contrast to fossil fuels, 
which are concentrated in a limited number of countries.

Rapid deployment of renewable energy and energy efficiency technologies is resulting in significant 
energy security, climate change mitigation, and economic benefits.
In international public opinion surveys there is strong support for promoting renewable sources 
such as solar power and wind power.

While many renewable energy projects are large-scale, renewable technologies are also suited to rural 
and remote areas and developing countries, where energy is often crucial in human development.
As most of the renewable energy technologies provide electricity, renewable energy is often deployed 
together with further electrification, which has several benefits."""
