Renewable energy sources

Renewable energy sources (RES) are energy sources that can be regenerated or renewed in a short time horizon. This means that their use does not exhaust these resources and does not contribute to their depletion. RES are a key factor in efforts for sustainable energy and reduction of greenhouse gas emissions. These energy sources fall into several main categories:

Solar energy: This category includes the use of solar radiation energy to produce electricity or thermal energy. Solar panels (photovoltaic systems) convert sunlight into electricity, while solar collectors use sunlight to heat water.

Wind Energy: Wind turbines capture energy from the wind and convert it into electricity. Wind farms are often placed in suitable locations with sufficient wind energy.

Hydropower: This category includes hydropower (water to move turbines) and ocean power (waves and currents). Hydroelectric power plants, including tidal power plants and tidal power plants, use water power to generate electricity.

Biomass: Biomass includes organic material such as wood pulp, agricultural waste material and forest products. This biomass can be burned to produce heat or electricity or processed into biofuels such as biogas or second-generation biofuels.

Geothermal energy: This energy is obtained from the geothermal heat inside the Earth. Geothermal power plants and heat pumps use this energy to produce electricity or to heat and cool buildings.

Ocean Energy: Ocean energy uses the energy of currents, waves, or temperature differences in the oceans to produce electricity or other forms of energy.

Renewable energy sources are a key element in the transition to sustainable and environmentally friendly energy, because they do not emit greenhouse gas emissions and do not contribute to climate change. Their use is currently an active area of research and investment with the aim of increasing their share in total energy and reducing dependence on fossil fuels.
