Renewable energy sources (RES) are those that harness natural processes in the environment, such as wind, sun, water, biomass, or geothermal energy. RES are increasingly popular and desired because they offer numerous advantages compared to traditional energy sources like coal, oil, or gas. Some of these advantages include:

• RES are environmentally friendly as they do not emit harmful greenhouse gases or other pollutants contributing to global warming and climate change.
• RES are renewable, meaning they cannot be depleted and are available independently of geopolitical situations or commodity prices.
• RES are diverse and flexible, adaptable to various geographical conditions and energy needs.
• RES benefit the economy by creating new jobs, stimulating technological innovations, and reducing energy import dependence.

Among various types of RES, several main categories stand out:

• Wind Farms – also known as wind farms, they utilize the kinetic energy of the wind to power turbines that generate electrical current. Wind farms can be on land or at sea, depending on the location and wind conditions.
• Solar Energy – it employs solar radiation to produce heat or electrical current using photovoltaic panels. Solar energy, obtained, for example, with wind farms, is one of the cheapest and fastest-growing RES sources globally.
• Hydropower – it uses the potential or kinetic energy of water to power turbines or generators. Hydropower can be derived from rivers, lakes, oceans, or waves. It is one of the oldest and most reliable RES sources.
• Biomass – it uses organic material of plant or animal origin to produce heat, electrical current, or biofuels. Biomass can be obtained from agricultural, forestry, municipal, or industrial waste. It is one of the most versatile and accessible RES sources.
• Geothermal Energy – it harnesses the heat stored deep within the Earth to heat or cool buildings or produce electrical current. Geothermal energy is one of the cleanest and most stable RES sources as it is not weather-dependent or season-specific.

Renewable energy sources represent the direction of energy development worldwide. According to the International Energy Agency (IEA), the share of RES in global electricity production will increase from 29% in 2020 to 43% in 2030 and 60% in 2050. However, achieving these goals requires investments, policies, and cooperation at the local, national, and international levels.

One of the areas with significant potential for RES development is alternative energy. It encompasses various forms of energy production, distribution, and consumption that are alternatives to the traditional model based on fossil fuels and centralized energy grids. Some examples of alternative energy include:

• Microgrids – these are local energy systems that can operate independently or in conjunction with the main grid. Microgrids use RES, energy storage, and smart technologies to ensure reliable and efficient energy access for users.
• Hydrogen Economy – this envisions hydrogen as the primary energy carrier, produced from RES, stored, transported, and used for various purposes such as vehicle propulsion, building heating, or industrial power.
• Prosumers – these are individuals or entities that both produce and consume electrical energy. Prosumers can install their RES sources, like photovoltaic panels or wind turbines, and sell surplus energy to the grid or share it with other users.

Alternative energy offers many benefits to society and the environment, such as:

• Enhanced energy security and reduced dependence on foreign energy suppliers.
• Lower energy costs and a reduction in energy poverty.
• Improved air quality and public health by lowering pollutant emissions.
• Support for local communities and economies by creating jobs and income.
• Acceleration of the energy transition and the fight against climate change by reducing greenhouse gas emissions.

To fully exploit the potential of alternative energy, comprehensive RES solutions are required, integrating various technologies, services, and stakeholders into a sustainable energy system. Such solutions demand innovation on multiple levels, such as:

• Technology – developing new or enhancing existing RES technologies, such as higher-efficiency photovoltaic panels, quieter wind turbines, or higher-capacity batteries.
• Business – creating new or adapting existing RES business models, like equipment leasing, participation in energy communities, or offering energy management services.
• Policy – introducing new or amending existing RES regulations and tax laws, such as setting energy tariffs, offering investment incentives, or issuing energy certificates.
• Society – building new or strengthening existing social and cultural relationships related to RES, such as citizen engagement, education, environmental awareness, or cross-sectoral cooperation.
