Wind technology is considered to be among the most promising types of renewable energy sources, and due to high oil prices and growing concerns about climate change and energy security, it has been the subject of extensive considerations in recent years, including questions related to the relative sustainability of electricity production when the manufacturing, assembly, transportation and dismantling processes of these facilities are taken into account. The present article evaluates the environmental impacts, carbon emissions and water consumption, derived from the production of electric energy of the Villonaco wind farm, located in Loja-Ecuador, during its entire life cycle, using the Life Cycle Analysis method. Finally, it is concluded that wind energy has greater environmental advantages, since it has lower values of carbon and water footprints than other energy sources. Additionally, with the techniques Cumulative Energy Demand and Energy Return on Investment, sustainability in the production of electricity from wind power in Ecuador is demonstrated; and, that due to issues of vulnerability to climate change, the diversification of its energy mix is essential considering the inclusion of non-conventional renewable sources such as solar or wind, this being the only way to reduce both the carbon footprint and the water supply power.

Nowadays, the high environmental sensitivity and economic constraints, as well as future prospects for development, require a strong sustainable energy policy. Such policies should be based on the local resource valorization – which gains more emphasis in ultra-peripheral territories as the case of the Madeira and Canary Archipelagos. In fact, renewable energy sources become more competitive from the economic point of view – however, with high environmental and social benefits in both Archipelagos. Thus, the local policies of Porto Santo Island will be inspired on the neighbor archipelago (Canary Islands), more specifically in the El Hierro Island – which is one of the worldwide leaders in sustainability issues. Contextually, the work enables a view through the cooperation perspective, highlighting sustainability strategies in Porto Santo Island (Madeira, Portugal) and El Hierro Island (Canary, Spain). Therefore, it will address diverse forms of energy production through natural resources with influence on spatial planning.

Renewable energy can potentially be a source of competitive advantage, reduce greenhouse gases, and counter climate change. This study utilizes Multi-Criteria Decision Analysis to systematically assess the relative attractiveness of multiple renewable energy forms based on three factors: 1. business (economic), 2. technical (environmental), and 3. social (regulatory). It uncovers the relative attractiveness of various renewable energy forms and suggests strategies for their development for providers and customers. After considering multiple factors, the study found hydro, geothermal, and wind power to be relatively attractive renewable energy sources.

This paper focuses on the use of renewable energy sources in Serbia and the Republic of Srpska and their impact on the environment and climate change. Renewable energy sources used in Serbia are hydropower, solar energy, wind energy, biomass, and biogas. Renewable energy sources used in the Republic of Srpska are hydropower, solar energy, biomass, and biogas. When using hydropower, the formed reservoirs often impact the microclimate of the environment in which they are located. Photothermal and photovoltaic solar radiation conversion installations are mostly stationary, do not emit harmful substances into the environment, and have no impact on climate change. The use of wind turbines has a certain influence on the flow of ambient air. When using biomass and biogas, combustion gases are released into the atmosphere, which has slightly negative impact on climate change. The paper concludes that the use of renewable energy sources in Serbia and the Republic of Srpska has a negligible negative impact on the environment and climate change.

It is well-known that, in the past decades, the burning of fossil fuels was identified as the major cause of climate change. Climate change mitigation is becoming a central concern of global society. Limiting global warming to below 2 °C above the temperature of the pre-industrial period is the key to preserving global ecosystems and providing a secure basis for human activities, as well as reducing excessive environmental change. The ambitions increased at an accelerated pace with a dramatic expansion of net zero-emission targets. Increasing pressure from citizens and society has forced countries to intensify their climate plans, while the private sector has bought a record amount of renewable energy. An energy system based on fossil fuels must be replaced by renewable energy with low carbon emissions with improved energy efficiency. That applies to all consumers of fossil energy: cities, villages, building sectors, industry, transport, agriculture, and forestry. The paper explores and presents the strategy of energy development of renewable energy sources in the world. The application of new technologies that have led to developing renewable energy sources is presented in detail: wind energy, solar energy, small hydropower plants, biomass, and their increase in the total share of energy production, i.e., reduced fossil fuel use in energy production. Investments in new technologies used in renewable energy sources have led to increases in employment worldwide. Analysis of the trend of increased energy production from RES (Renewable Energy Sources) with investment plans, the employment rate for each energy source, and the development of renewable energy sources in the coming period are provided.
