"[Croenergo.Sub.2]"--Future of Renewable Energy Sources (Report‪)‬

1. INTRODUCTION Humanity gained energy through thousands of years by burning wood and other biomass for cooking, shaping metals and heating. Since medieval times man adapted rivers for river plants and windmills to grind corn. Energy from renewable sources is not a novelty. The history of the first hundred or more years of production of electricity shows us that apart from development of energy from the water almost all production technologies are based on the burning of coal, oil and gas, and in recent times nuclear fission. These thermal technology productions of electricity have significant advantages, and that is the ability to convert them to gain energy of high concentration which is accordingly of low volume requirements. Established technologies were subject to continuous and intensive development. They are mainly designed to connect to each other on associated network systems, starting from 1920, at a regional, national or international level. The goal was to connect and supply easily available and reliable electricity with the appropriate combination of power plants at the lowest possible costs. Social and environmental impacts of supply electricity until recently had limited importance.
