Renewable energy comes from a source that will not deplete. Two common examples of this type of energy are solar power and wind power. Geothermal power, hydropower, biomass, and tidal power are additional forms of renewable energy that produce power for our planet right now.
Renewable energy sources are still not the predominant energy resource in the energy sector, although in certain developed countries they participate in a significant share in electricity generation. Renewable energy sources appear as an additional source of energy in the conventional electro-industry. The main reason for the increasing investment and exploitation of renewables is certainly environment preservation and environmental aspect of sustainability.
The purpose of this paper is to determine the advantages and disadvantages of renewable energy sources utilization in general, without considering the individual type of renewables, such as wind or solar energy. Thereby, the paper presents numerous advantages of using renewable energy in the electricity generation, such as environment preservation in terms of reduced greenhouse gas emissions or improvement of innovations and technical/technological development. There are also presented certain disadvantages of renewables in the production of electricity, such as dependence on weather conditions or low energy efficiency and low ability to produce electricity.
This work will represent opinions and thoughts of different scientists, sociologists and politics related to the most discussing topic now days, renewable sources of energy.
Keywords: Renewable energy, limitations, emissions, greenhouse gases, production of electricity, weather conditions or low energy efficiency etc.
