| Summary/Abstract |
The development of renewables has attracted abundant attentions. However, existing studies have not recognized the potential impetus of Information and Communication Technologies (ICTs) on renewables. In this study, we explore the impact of mobile ICTs on renewable energy generations in seven countries including USA, Canada, UK, Germany, Italy, Netherlands and Poland. As revealed by static and dynamic empirical analyses of 19-year data, there exists significantly positive relationship between the renewables and ICTs at the macro-level. One percent increase of ICTs would lead to 0.2/1.1% increase for renewables in the long/short terms. Thus, ICTs can promote the development of renewables, and policy makers should consider full integration strategies between renewables and ICTs. Besides ICTs, factors positively affecting renewables include economic developments (long/short term), primary energy consumptions and carbon reductions (short term), and population growth (long term). Interestingly, natural gas competes with renewables in the short term, while it compliments renewables in the long term.

Government of India decided to observe the birth anniversary of Dr. Babasaheb Ambedkar on April 14 as “Water Day” to sensitize people on managing the precious natural resource.1 Dr. Babasaheb Ambedkar is known as the ‘Architect of the Constitution of India. However, he is less known in the field of water resources.

| Summary/Abstract |
New renewable energy generators such as solar photovoltaics and wind turbines have the ability to be sited in a more decentralized manner than conventional generators such as coal, nuclear, hydroelectric, or natural gas plants. However, at the commercial scale, these new renewable generators are often built in existing generation corridors and are not necessarily more decentralized. This paper analyzes the degree of centralization of generators in the contiguous U.S. between 2001 and 2018 and identifies the state level policies that may be driving differences in the degree of centralization between states and regions. The results show that community solar programs such as those in North Carolina and Minnesota have driven greater decentralization of generation while community choice aggregation programs such as those in California have not led to greater decentralization of generation. The degree of centralization of generation assets has implications for sociotechnical systems, communities, energy security, and resiliency against manmade and natural disasters.

| Summary/Abstract |
China's industrial transformation of the past thirty years, when its GDP has been increasing by an average of 10% per year, has been underpinned by an energy industrial revolution. Electrical energy is the driver of this transformation, with China utilizing latecomer advantages in building an electrical energy generation machine of prodigious size. In terms of electrical energy generated, China's system has expanded twelve-fold in 30 years, from 280 TWh in 1980 to over 3500 TWh in 2010. In this paper we describe the principal features of this remarkable transformation, examining the official projections to 2020, the semi-official projections to 2050, and offering our own projections based on observed logistic industrial dynamics for the uptake of renewable energies as well as the continuing role to be played by fossil fuels, particularly coal. We emphasize the role to be played by China's construction of a 'strong and smart' electric power grid, as envisaged in the 12th Five Year Plan released in March 2011, and the complementary proposals to build a national high speed rail system. We see China as on track to phase out fossil fuels altogether in its power production system by the end of the century. We develop an argument as to why it might be expected that fossil fuel utilization will decline while renewable energy utilization might increase in China, constituting a genuine energy industrial revolution.

| Summary/Abstract |
Several projects in the European Union (EU) are currently under development to implement the carbon capture, transport and storage (CCS) technology on a large scale and may be subject to public funding under EU support initiatives. These CCS projects may develop any combination of three types of operating levels: pilot, demonstration and full-scale, representing progressing levels of electric power generation capability. Several projects have commenced at the demonstration level, with full-scale commercial levels planned for approximately 2020. Taking the perspective of a funding agency, we employ a real options framework for determining an optimal project selection and funding strategy for the development of full-scale CCS plants. Specifically, we formulate and solve a stochastic dynamic program (SDP) for obtaining optimal funding solutions in order to achieve at least one successfully operating full-scale CCS plant by a target year. The model demonstrates the improved risk reduction by employing such a multi-stage competition. We then extend the model to consider two sensitivities: (1) the flexibility to spend that budget among the time periods and (2) optimizing the budget, but specifying each time period's allocation a priori. State size and runtimes of the SDP model are provided
