| Summary/Abstract |
This study investigates the effect of renewable energy production on water and land footprint in 58 developed and developing countries for the period of 1980–2009. Utilizing the ecological footprint as an indicator, the fixed effects, difference and system generalized method of moment (GMM) approaches were employed and eight different models were constructed to achieve robustness in the empirical outcomes. Despite the use of different methods and models, the outcome was the same whereby GDP growth, urbanization, and trade openness increase the water and land footprint. Moreover, renewable energy production increases the water and land inefficiency because of its positive effect on ecological footprint. Additionally, based on the square of GDP it is concluded that the EKC hypothesis does not exist while the square of renewable energy production indicates that renewable energy production will continue to increase water and land footprint in the future. From the outcome of this study, a number of recommendations were provided to the investigated countries.

| Summary/Abstract |
According to the Sustainable Development Goals (SDGs), the principal threats to human well-being encompass both non-renewable and renewable energy sources, alongside a mounting environmental deficit, which aligns with the targets of SDG-7 and SDG-13. This study explores how environmental technologies, financial growth, and energy use influence the ecological footprint and green growth in the top-ten countries with the biggest ecological footprint from 1990 to 2019. Environmental innovations, green growth, and renewable energy improve the environment, while financial expansion and the use of non-renewable energy have been shown to be detrimental to the environment. Financial expansion, ecological impact, and non-renewable energy constrain green growth. However, environmental innovation and renewable energy deployment have a cumulative effect on green growth. Moreover, the results of the panel causality approach signpost a bidirectional causal association between environmental innovations, green growth, non-renewable and renewable energy, and ecological footprint. Nevertheless, it is observed that there exists a unidirectional causal relationship from financial development to ecological footprint and green growth. Moreover, this paper provides an in-depth evaluation and offers significant policy recommendations, both in a general sense and specifically targeted towards countries with the highest ecological footprints.

| Summary/Abstract |
Conceptual and empirical work on socio-technical transitions, such as energy transition strategies, often disregard the limited planetary capacity of available land. This paper explores the trade-offs between energy transition pathways and land use in different geographical contexts. We draw on empirical data from three contrasting case-study countries: Vietnam, New Zealand and Finland. An enhanced calculation model based on the Ecological Footprint method is used to assess land consumption for different transition pathways towards a low-carbon society. More specifically, the spatial impacts of the energy sector and its carbon dioxide emissions are assessed for different timeframes, namely the past, the present and future scenarios (by 2030 and the 2040s) based on the national energy strategies of these countries. The results show a lack of consideration in these strategies of the land area required to ensure an adequate implementation for each national territory. Hence, we argue for an acknowledgement of spatial factors, namely land availability and the geographical context, in theories and policy strategies on socio-technical transitions.

| Summary/Abstract |
The purpose of this paper is to measure the ecological footprint (EF) of energy and electricity consumption by the residents of an Irish city-region, in terms of the land area required to sequester carbon emissions from energy and electricity consumption and to support energy infrastructure and development. The EF was also used to analyse the impact of potential scenarios and policies and results were compared with the business as usual (BAU) projection in order to identify the optimal policy measure. It was found that the total EF for domestic energy and electricity consumption by Limerick residents increased by 7% from 0.125 global hectares (gha) per capita in 1996 to 0.134 gha per capita in 2002.
The EF was then used to assess different policy measures or scenarios. It was concluded that Scenario 2, which proposes reducing energy and electricity consumption, was the most preferable option, and Scenario 4, which proposes increasing the contribution of short rotation coppice (SRC), the least preferable option. This suggests that absolute reduction and demand management should be prioritised over renewables substitution in a policy hierarchy. Of the renewable energy scenarios, Scenario 4 has the highest EF as a result of land appropriation for biomass production.

| Summary/Abstract |
In today's global energy mix with a share of 80% fossil energy, the growth of the world population and energy demand will lead to a conflict between stable ecosystems and global welfare. The inspection of social indexes of welfare and happiness leads to the following energy plan: high-income countries with a current annual energy demand of up to 8 tonnes of oil equivalent per capita (toe pc) have to reduce their demand to 2 toe pc, which should be sufficient without cutback in welfare. Vice versa, low-income countries increase their demand until 2 toe pc are reached. Compared to today this scenario (2 toe pc, 9 billion people by 2050) leads to an increase of the ecological footprint from today 1.3 to 2 planet Earths in today's technologies. The only solution to provide 2 toe pc without damaging the biosphere is a reduction of the CO2 footprint with a current share of 50%. A complete shift from fossil fuels to renewables would half the ecological footprint as needed for the desired footprint of one planet Earth. To reach this goal, one or more forms of solar power and/or nuclear power are needed, as the potential of non-solar renewables is too small.
