Abstract Policy support for renewable energy has increased considerably over the past decade. Two drivers underpin this trend: first, the effort to constrain growth in greenhouse-gas emissions and secondly, the concerns to diversify the supply mix (promoted particularly by high oil prices, especially in 2005–2008). To address these concerns, more and more governments are adopting targets and taking measures to increase the share of renewables in the energy mix. Worldwide, traditional and modern renewables together supplied 27% of total demand for heat, or 1059 Mtoe, in 2008. This increases to nearly 1400 Mtoe (1 Mtoe = 42 PJ) in 2035 in the New Policies Scenario, meeting 29% of total demand for heat. The share of modern renewables in total renewables for heat grows from 29% to 48%. This paper is a comparison analysis of the global and the Hungarian renewable energy trends.

The Cost

Heat accounts for about one-third of the final energy use and it is mostly produced using fossil fuels in South Korea. Thus, heat production is an important source of greenhouse gas emissions. However, using renewable heat that is directly produced from renewable energy, such as bioenergy, geothermal, or solar heat can save energy and reduce greenhouse gas emissions, rather than transforming conventional fuel into heat. Therefore, an energy policy for renewable heat urgently needs to be established. It is such situations that this paper attempts to assess the consumers’ additional willingness to pay (WTP) or the price premium for renewable heat over heat that is produced from fossil fuels for residential heating. To that end, a nationwide contingent valuation survey of 1000 households was conducted during August 2018. Employing the model allowing for zero WTP values, the mean of the additional WTP or premium for one Gcal of heat produced using renewable energy rather than fossil fuels was estimated to be KRW 3636 (USD 3.2), which is statistically meaningful at the 1% level. This value represents the price premium for renewable heat over heat that is based on fossil fuels. Given that the heat price for residential heating was approximately KRW 73,000 (USD 65.1) per Gcal at the time of the survey, the additional WTP or the price premium corresponds to about 5% of that. When considering that the cost of producing renewable heat is still significantly higher than the cost of producing fossil fuels-based heat, more efforts to lower the production costs of renewable heat as well as financial support of the government for producing and supplying renewable heat are needed to ensure residential consumers’ acceptance of renewable heat.

Standards as a controlling mechanism: Methods and effects of carbon footprinting in the logistic sector. Carbon footprints describe the greenhouse gas emissions of predefined objects, such as products, companies, persons or transport units. Corresponding emission calculation standards have been developed and their application increased over the past decade. The article discusses this development, the current state of implementation and open questions regarding application and harmonization using the example of the logistic sector. Additionally, the author explores the question, how carbon footprints contribute to CO

The Impact

According to the objectives of the European Union concerning the climate changes, Member States should take all the necessary measures in order to reduce the greenhouse gas emissions. The aim of this study is to identify the causality relations between greenhouse gases emissions, added value from agriculture, renewable energy consumption, and economic growth based on a panel consisting of 11 states from the Central and Eastern Europe (CEECs) in the period between 2000 and 2017. The Autoregressive Distributed Lag (ARDL) method was used to estimate the long-term relationships among the variables. Also a Granger causality test based on the ARDL – Error Correction Model (ECM) and a Pairwise Granger causality test were used to identify the causality relationship and to detect the direction of causality among the variables. The results obtained reveal, in the long term, two bidirectional relationships between agriculture and economic growth and two unidirectional relationships from agriculture to greenhouse gas emissions and renewable energy. In the short term, four unidirectional relationships were found from agriculture to all the variables in the model and one unidirectional relationship from renewable energy to greenhouse gas emissions.

The City

Urban rooftops are a potential source of water, energy, and food that contribute to make cities more resilient and sustainable. The use of smart technologies such as solar panels or cool roofs helps to reach energy and climate targets. This work presents a flexible methodology based on the use of geographical information systems that allow evaluating the potential use of roofs in a densely built-up context, estimating the roof areas that can be renovated or used to produce renewable energy. The methodology was applied to the case study of the city of Turin in Italy, a 3D roof model was designed, some scenarios were investigated, and priorities of interventions were established, taking into account the conditions of the urban landscape. The applicability of smart solutions was conducted as a support to the review of the Building Annex Energy Code of Turin, within the project ‘Re-Coding’, which aimed to update the current building code of the city. In addition, environmental, economic, and social impacts were assessed to identify the more effective energy efficiency measures. In the Turin context, using an insulated green roof, there was energy saving in consumption for heating up to 88 kWh/m2/year and for cooling of 10 kWh/m2/year, with a reduction in greenhouse gas emissions of 193 tCO2eq/MWh/year and 14 tCO2eq/MWh/year, respectively. This approach could be a significant support in the identification and promotion of energy efficiency solutions to exploit also renewable energy resources with low greenhouse gas emissions.

Energy Efficiency Standards

Despite efforts by some congressional legislators to pass laws to limit greenhouse gas emissions and reduce the use of fossil fuels, no such laws have yet been adopted. Is this failure to pass new laws attributable to a lack of public desire for such legislation? Data from national surveys support two answers to this question. First, large majorities of Americans have endorsed a variety of policies designed to reduce greenhouse gas emissions; second, policy support has been consistent across years and across scopes and types of policies. Popular policies include fuel economy and energy-efficiency standards, mandated use of renewable sources, and limitations on emissions by utilities and by businesses more generally. Support for policies has been price sensitive, and the American public appears to have been willing to pay enough money for these purposes to cover their costs. Consistent with these policy endorsements, surveys show that large majorities of Americans believe that global warming has been happening, that it is attributable to human activity, and that future warming will be a threat if unaddressed. Not surprisingly, these beliefs appear to have been important drivers of public support for policies designed to reform energy generation and use. Thus, it seems inappropriate to attribute lack of legislation to lack of public support in these arenas.
