The Potentials of Renewable Energy

Renewable energy flows are very large in comparison with humankind’s use of energy. Therefore, in principle, all our energy needs, both now and into the future, can be met by energy from renewable sources. Technologies exist that convert renewable energy flows to modern energy carriers or directly into desired energy services. Renewable energy now provides 14 percent of the world’s primary energy, mostly traditional biomass, and 20 percent of electricity, mostly hydropower. Technological development during the last decade has resulted in modern renewable energy supply becoming competitive in many situations. Further technological development and industrial learning will continue to bring costs down. [via]
