Renewable Resource

Global climate change and land degradation are two grand changes facing humanity. In this perspective, we examine how degraded and abandoned farmland can be harnessed to fight climate change. Building upon and extending natural climate solutions, we suggest that the carbon capture and storage of abandoned farmland can be accelerated and maximized through restoring the diversity of plant species, applying biochar to soil, and co-developing renewable energy such as solar power. The benefits of these approaches extend far beyond climate-change mitigation and land restoration.
Although numbers are still low compared to cattle rearing, intensive dairy goat farms have been widely spreading in the Italian livestock systems. Since goats are quite rustic, they can easily adapt to different management practices; however, improving the efficiency can make the difference, both in productivity and on the environmental impact attributed to goat milk production. In the present study, the Life Cycle Assessment (LCA) approach was used to quantify the potential environmental impact of goat milk production system in 17 farms in Lombardy (Northern Italy).

Access to reliable, affordable and sustainable energy is essential for improving living standards, development and economic growth. From a healthcare perspective, energy is a critical parameter for delivering and improving healthcare services and life-saving interventions in the Global South. This review provides an estimation of the energy needs of different healthcare facilities as a function of patient capacity and services provided. It also presents the strengths and limitations of several energy sources that can be used to meet these needs.
Fossil fuel subsidies are a key barrier for economic development and climate change mitigation. While the plunge in international fuel prices has increased the political will to introduce fossil fuel subsidy reforms, recently introduced reforms may risk backsliding when fuel prices rebound − particularly if they fail to address the underlying mechanisms that create demand for low fossil fuel prices. Extant literature has mostly focused on the consequences of fossil fuel subsidies, including their economic or environmental impact, and the social contract that make their reform difficult.
Capacity planners in developing countries frequently use screening curves and other system-independent metrics such as levelized cost of energy to guide investment decisions. This can lead to spurious conclusions about intermittent power sources such as solar and wind whose value may depend strongly on the characteristics of the system in which they are installed, including the overall generation mix and consumption patterns.
This paper presents a review of exergy analysis of solar thermal systems. It includes both various types of solar collectors and various applications of solar thermal systems. As solar collectors are an important technology when sustainability is considered, exergy analysis, which gives a more representative performance evaluation, is a valuable method to evaluate and compare possible configurations of these systems. It should be noted that this review is based on literature published in the last two years.
This paper defines the concept of 4th Generation District Heating (4GDH) including the relations to District Cooling and the concepts of smart energy and smart thermal grids. The motive is to identify the future challenges of reaching a future renewable non-fossil heat supply as part of the implementation of overall sustainable energy systems.
Based on literature and six country studies (Belgium, Denmark, Finland, Netherlands, Sweden, Slovakia) this paper discusses the compatibility of the EU 2020 targets for renewable energy with conservation of biodiversity.We conclude that increased demand for biomass for bioenergy purposes may lead to a continued conversion of valuable habitats into productive lands and to intensification, which both have negative effects on biodiversity.
