Renewable energy sources

At the end of 20th and the beginning of 21th century, energy demand has increased and scientists attempted to find solutions for compensating this energy demand. On the other hand, with the increase of energy demand and consumption, scientist had to face another issue that our World?s energy resources are very limited and increasing demand is consuming our limited resources and polluting our World. This challenged the scientists to find new solutions like renewable energy sources that compensate our world?s energy demand without polluting and consuming limited energy sources.In this dissertation, information on technologies of renewable energy resources is given. Wind and solar energy are emphasized but geothermal, hydropower, wave, tidal, biomass and hydrogen energies are also discussed. Current information and proposals on renewable energy applications, policies, laws, institutions and R&D studies in Turkey are given.
