This paper aims to analyse: (a) how the attitude towards renewable energy-based heating systems, pro-environmental behaviour and the perceived attributes of technology influence intention to convert residential heating systems from fossil fuels to biofuels, and (b) the moderating role of culture based on Hofstede’s individualism dimension. A total of 425 responses were collected from a panel of internet users from representative countries in three continents (the United States, the United Kingdom and South Africa); the data analysis was carried out using structural equation models in a multigroup analysis. The results showed that attitude towards renewable energy-based heating systems is influenced by environmental variables in the United States and the United Kingdom, and by the perceived attributes of clean residential heating systems in the United States and South Africa. Attitude, in turn, impacts on the intention to convert from fossil fuels to biofuels. In addition, individualism has a moderating effect between these variables and there are intercultural differences in the degree of importance attributed to them. The study concludes the use of these energy systems as drivers of environmentally-sustainable development.

Subject Renewable energy in the Caribbean. Significance At the Summit of the Americas on April 10-11, US President Barack Obama said that the United States would help Caribbean countries develop renewable energy sources. The Caribbean had an average cost of 0.33 dollars per kilowatt-hour (kWh) in 2012, nearly three times the US cost of electricity -- a considerable economic burden, not just in the region, but in nearly all island economies. Impacts The World Bank may attract attention as a focus point for investment less politically contentious than the United States or Venezuela. Renewable energy concepts may be first tested in Puerto Rico, which offers US legal protection to investors. Low oil prices may aid the shift to renewables in the region, by damaging Venezuela's regional influence.

As two super powers in energy consumption and carbon emission, the United States and China have been striving to develop clean energy in recent years. In this paper, we study the international competitiveness and potential for trade cooperation in clean energy between the two countries. This paper reveals that the United States has comparative advantages in terms of biomass energy and nuclear power, while China has comparative advantages in terms of solar energy and wind energy. The two countries have a strong complementarity in solar energy, biomass energy and nuclear energy with exporting from the United States and importing from China. In solar energy and wind energy a strong complementarity has been formed with exporting from China and importing into the United States. So the two countries have a strong potential for cooperation. Meanwhile, the potential trade cooperation is enhancing with the United States accelerating the development and exportation in natural gas. Therefore, the two countries have a strong trade complementarity on clear energy and a strong potential for cooperation in general. At the same time, the VCR model is built based on the clean energy Trade Complementary Index(TCIc and TCIu) between the United States and China. It can be found that the clean energy trade cooperation helps to curb CO2 emissions and promotes the GDP growth in the United States. However, China is in the early stage of clean energy development, the cooperation would cause a decline of GDP in China.

Market Demand

Despite a lack of action at the national level, the transition to carbon-free energy is becoming a reality across the United States. At the local level, community choice aggregators (CCAs)—which offer communities public control over their electricity purchasing decisions—are accelerating this transition. By forming these electricity providers, member cities and counties can choose how much renewable energy is offered to their residents and businesses. In California, CCAs have become an effective policy tool at accelerating the transition to clean energy. Across the state, 182 cities and counties have become members of one of the 23 CCAs, with additional communities planning to join or form CCAs in the next few years. These CCAs have been effective at unlocking market demand largely stifled by an investor-owned utility monopoly by giving cities and counties greater choice and access to renewable energy. The vast majority of these CCAs procure more renewable energy than the investor-owned utilities they compete with. As a result, CCAs purchased 204% of the renewable energy required by the state from 2011 to 2019. By achieving California’s carbon-free energy targets more quickly than mandated, the state benefits from a cumulatively larger reduction in greenhouse gas emissions each year. The success of CCAs in California demonstrates the power of promoting carbon-free energy at the grassroots, enabled by public, local choice in electricity supply. With six states considering CCA-enabling legislation, and with hundreds of cities and counties across the United States working toward a 100% carbon-free energy goal, policies like California Assembly Bill 117 (2002) that enabled CCAs can provide a valuable tool to accelerate the transition to carbon-free energy. The purpose of this paper is to assess how CCA-enabling policy can support the clean energy transition using California as a case study. We assess three conditions that affect a CCA’s ability to accelerate the clean energy transition: CCA customer characteristics, CCA design features, and their policy and regulatory context. We conclude with a discussion of policy recommendations important to ensure CCAs can continue to support clean energy goals.

Loan Guarantees

Conceived as an idea to push financing toward underdeveloped clean energy technology to improve the environment, promote economic growth, and produce a more secure energy supply, the Title XVII loan guarantee program has likely failed to meet these objectives. Instead, it has been used as a political tool, exposed taxpayers to unnecessary risk, diverted funding from alternative clean energy investments, and primarily benefitted large, politically connected corporations.

Current Trends

Crisis related to distribution of COVID-19 requires significant state involvement in the response, which includes the definition of strategies formation and direct intervention in to the socio-economic processes. Governments of countries are addressing the development of stimulus and recovery packages strategies what have a goal to form in the future necessary potential for society and economy on the whole. In given environment, stable assets are needed, including an inclusive energy system capable of supporting energy development in accordance with the United Nations Sustainable Development Program and the 2016 Paris Agreement, this requires further research of the prospects for innovative development of renewable energy sector in the crisis of COVID-19 in the transition from the use of fossil fuels to the use of renewable energy sources. Global forecasts from the International Renewable Energy Agency, the International Energy Agency, and the US Energy Information Administration have suggested ways to transform the global energy system. China's hybrid energy market is showing an increase in wind and solar energy production. Reduced costs in the United States have stimulated an increase in renewable energy capacity. In Ukraine, the important role of alternative energy can be identified in the stabilization of Ukraine's agro-industrial complex. In the article reviews current trends and conditions in the development of the energy sector in the transition from the use of fossil fuels to the use of renewable sources in China, United States and Ukraine in terms of forecasting generation and justification of investment directions. A number of technical challenges and problematic aspects of management in the renewable energy sector in Ukraine are highlighted. Long-term goals are proposed for all stakeholders of the energy system in the transition from the use of traditional fuel to the use of biopropellant. The conceptual principles and prospects of scientific research in the formation of the National Renewable Energy Development Plan until 2030 are also outlined.

The Cost

The foreseeable energy future will be driven by economics of known technologies and the desire to reduce CO2 emissions to the atmosphere. Renewable energy options are compared with each other and with the use of fossil fuels with carbon capture and sequestration (CCS). Economic analysis is used to determine the best of several alternatives. One can disagree on the detailed costs, including externalities such as climate change and air and water pollution. But the differences in capital and operating costs between known technologies are so significant that one can draw clear conclusions. Results show that renewable energy cannot compete with fossil fuels on a cost basis alone because energy is intrinsic to the molecule, except for hydroelectricity. However, fossil fuels are implicated in climate change. Using renewable energy exclusively, including transportation and electricity needs, could reduce the standard of living in the United States by 43% to 62%, which would correspond to the level in about 1970. If capture and sequester of CO2 are implemented, the cost of using fossil fuels will increase, but they beat renewable energy handily as an economic way to produce clean energy.

Abstract. During the last decades, several studies have been conducted on the effectiveness of sexual abuse prevention programs implemented in different countries. In this article, we present a review of 70 studies (1981–2017) evaluating prevention programs, conducted mostly in the United States and Canada, although with a considerable presence also in other countries, such as New Zealand and the United Kingdom. The results of these studies, in general, are very promising and encourage us to continue this type of intervention, almost unanimously confirming its effectiveness. Prevention programs encourage children and adolescents to report the abuse experienced and they may help to reduce the trauma of sexual abuse if there are victims among the participants. We also found that some evaluations have not considered the possible negative effects of this type of programs in the event that they are applied inappropriately. Finally, we present some methodological considerations as critical analysis to this type of evaluations.
