PurposeIn order to compliment the growing use of renewable energies in the US, additional technologies must be employed on the bulk power system. This paper aims to forecast the most probable energy storage technologies.Design/methodology/approachThe methodology was deployed in two steps: evaluate the potential energy storage technologies that could complement a wind turbine or photovoltaic system; and forecast which of these technologies is best poised to become a viable solution to the energy storage problem facing these renewable technologies.FindingsBased on the publication and patent data, compressed air energy is set to be the fastest growing complimentary technology to wind energy. Two of these types of plants are currently in existence today as mentioned previously indicating the technology is commercially available. This technology has great potential; however, implementing this technology involves finding or creating underground airtight caverns in usable locations.Research limitations/implicationsThe number of variables have been limited due to the methodologies chosen for this analysis. The research can be expanded using other criteria such as cost, cost of capital, economies of scale, environmental concerns, social and political constraints.Originality/valueThis paper provides an assessment that was indicated as necessary by those who identified the need for the development of energy storage technologies for future electricity generation.

When regional autonomy was implemented, local government had control over the region. Local government could work because of local revenue. Without the local revenue, local government could not operating their programs. The higher the local income, the more possibility the region will be prosperous. Local revenue divided by two, there are original from region local revenue and granted revenue. Local revenue is obtained from local taxes. One of the local taxes is vehicle fuel tax. The contributions of vehicle fuel tax could be influence the original from region local revenue.

In many conflict zones around the globe - spreading from Sub-Saharan Africa to Eastern Europe and from the Middle East to Haiti - contingent troops, experts, staff officers, police and personnel are working under the umbrella of the United Nations (UN). Controls struggle to promote peace and stability, as well as maintain the rule of law and order. According to conflict resolution theorists, peacekeeping operations (PKO) are necessary for positive conflict transformation. Thus the UNPKO plays a fundamental role in maintaining world peace (Diehl, Druckman and Wall, 1998). The UN Peacekeeping's mandate is unique in terms of global partnership. It is set by the UN General Assembly and the UN Security Council (UNSC); consent of the host country is needed, as is that by troop and police contributors (What is peacekeeping, 2020). UN peacekeeping troops help countries navigate the challenging path from conflict to stability. However, as the UN doesn't have a regular army, it relies on member states troop to carry out Peacekeeping Operations in conflict areas. This research demonstrates that well-equipped and trained UN peacekeeping operations promote peace and stability more efficiently. The paper centres on an important question: what motivates the willingness of member states to contribute with troops to the UNPKO. We found that states experiencing inter-state rivalry and with struggling economies tend to contribute more troops than great powers and wealthy states. Bellamy and Williams' Model and Middle Power theory are used here so as to better analyse the rationale of troops contribution in PKO. China as a case study is also used in the paper.

This article seeks to undertake a critical assessment of the changing position of public science in the entrepreneurial ecosystem of the countries on the periphery of European research. These countries are driven by new innovation paradigm based on entrepreneurship, which are implemented within the European Smart specialization strategy (S3). This article argues that S3 is widely implemented in the cohesion countries and, while it provides substantial resources for science, technology, and innovation, it fails to provide sustainability in the public research sector. This has direct implications for policies concerning innovation and entrepreneurial ecosystems. In order to prove the thesis, the article provides theoretical argumentation for emergence of a new innovation paradigm, driven by the rise of the entrepreneurial ecosystem, its incorporation into S3, and a consequent retreat of science policy in favor of entrepreneurial policy. The empirical analysis is focused on the funding trends seen in the business and public research sectors over the last decade (2008–2017), which have clearly shown that S3 has not contributed, despite expectations, to an increase in public expenditure for science. This signifies S3's neglect of public research within entrepreneurial ecosystems and challenges the ability of S3 to reduce wide disparities in research and innovation performance across the European Union. This ultimately endangers the innovation potential of the entrepreneurial ecosystem itself.
