Amidst the hype of a ‘new’ energy regime in India with a singular focus on renewable energy, this paper offers a more scrupulous reading of renewables to set up a critical energy discourse. It offers a three-part analysis where it begins by questioning the entrenched idea of ‘renewables as science’ and its instrumental use of metrics and measurements to convey an unbelievable reach and significance. Highlighting the consistent invocation of a calculative ethos, it shows how an ‘empirics of targets’ relying largely on the lure and lore of a single numeric, installed capacity, is persuasively employed to gloss over the crucial distinction between the potential and reality of renewables. An associated consequence is not only its pegging to the speculative value of market-based energy production but also that it remains rooted in the assumptions of an existing system, that is, the logic of a carbon lifeworld. Renewables, as a result, display the tell-tale sign of a sustainability paradox, raising questions about their ability to master a transition to a post-fossil performativity, exasperated as they are by internal contradictions embedded within their core characteristics – efficiency/sufficiency and, more importantly, tensions between utilities and infrastructure. With loose connections to parallel initiatives such as the Smart Cities Mission, the transformative potential of renewables is undercut as it remains embedded within an abstract grid imaginary, challenging any effort to actualise it in and through the urban.

Set Up

The Clean Energy Resource Teams (CERTs) is a project designed to give local citizens and other stakeholders a voice in planning and determining their energy future. In total, there are seven CERTs operating in seven regions across Minnesota, USA. CERTs connect citizens with technical expertise to facilitate planning and implementation of energy conservation and renewable energy projects. These technical resources are helping the teams identify and prioritize the most appropriate and cost-effective opportunities within their regions. This paper will describe one of these energy teams (the Northeast CERT) and its efforts in promoting clean energy production and conservation. A key product of the Northeast CERT is a strategic energy plan that highlights the region's top energy priorities. As part of its project priorities, the Northeast Minnesota CERT is working to set up demonstration projects at every school and community in the region. Toward this goal, the team is currently collaborating with two schools in the region to set up renewable energy projects such as wind and solar, which in turn would help students to understand that renewables and conservation can and should be an integral part of our energy system.

There is significant regional heterogeneity in terms of relative positioning in relation to the issue of sustainability and, in particular, in relation to the implementation of renewable energy. For this reason, the aim of this work is to analyze whether these differences in attributes for each region are likely to condition the expansion of renewable energy production. In this paper, we focus on wind energy. Therefore, the evolution of the installed capacity of wind energy is studied for a set of Spanish regions over the period between 2004 and 2017. The results obtained confirm that, in effect, there are factors linked to investment and environmental knowledge capable of conditioning the deployment of wind energy at the regional level.

<span>The use of new energy sources to replace traditional energy sources is the worldwide interest based on its irrefutable advantages, especially in regions where supply systems Power supply cannot reach. The devices installed capacity has a significant effect on the economy as well as on system operation. In this paper, formulate and solve the problem of optimizing installed capacity for devices (generators, charge controllers, storage, inverters) that are used in independent renewable energy systems. In illustrating this method of calculation, we apply it on a standalone system, i.e., it is not connected to the power supply grid.</span>

Energy Expansion

While overall power generation in India has been increasing over the years, the coverage of households in the energy access net (with 38% of total households or over 500 million people having no energy access) and availability of supply (at only 5-6 hours/day) are still prime concerns for the Government.  In such a scenario, is renewable energy an alternative given the shortage of supply from conventional sources, with over 30,000 MW stranded power plants, commitment of the Government to set up 100 Smart Cities, High-speed/Semi-speed Rails, Industrial Corridors and more beyond that ‘power to all’ by 2022’ Through this study, an attempt has been made to understand the socio-economic-environmental impact of renewable energy expansion and examined the factors that govern the feasibility and/or viability in meeting the ambitious clean energy target of 175 GW set out by the Government. The key determinants of renewable energy are found to be functionality variation, pattern of household’s energy consumption, willingness-to-pay, behavioral change in tariff and cost, grid integration, energy efficiency and access to cheap green finance. Selective implementation of a combination of On-Grid, Off-Grid and localized Mini-Grids application and flexible revenue modality such as ‘Pay as-you-go’ in off-grid areas and ‘Net-metering’ or ‘Feed-in-tariff’ concept in grid-connected areas are best suited. Further, enforceable renewable purchase obligation, renewable generation obligation, faster and efficient implementation of renewable energy certificates as tradable commodity, carbon trading as a source of revenue, green marketing, mobilization of funds under corporate social responsibility and single procurement of all renewable energy by a centralized unit would go a long way in achieving the renewable targets.

AbstractThe energy turnaround created a high volatility in the energy production based on renewable energy. To integrate renewable energy economically in buildings and smart cities an additional concept of energy storage and energy supply based on energy management concepts must be claimed. The political views have changed during the last years and energy efficiency in buildings is seen important because 35% of greenhouse gas is produced by the final energy consumption. The deployment of local energy production concepts is an important step to energy turnaround. To generate and distribute energy effectively in buildings, digital components such as sensors, actuators, meters, and energy management systems must be installed in the buildings and the digital components must be able to communicate via communication networks. The paper describes systems for local energy generation, necessary communication networks for buildings and smart cities and digitization applications in industrial buildings. As an example of energy management, the Oktett64 system is presented, which is based on Enterprise IT technology and has implemented AI and blockchain technology. Digitalization with platforms such as Oktett64 are based on technologies that are superior to today's often commercially available Programmable Logic Controllers. The article also shows how the future mobile communications standards 5G beyond and 6G can offer special solutions for the digitization of buildings in their edge clouds.

The article discusses the main problems of the using of biomass as a fuel, including the fuel use of biomass as an innovative way to generate clean energy. It is shown that according to the development of technology for the production of renewable energy sources, energy costs will decrease, and the operating time of the devices and, accordingly, their productivity will increase. Ultimately, this will allow to get a positive result, i.e. reduce harmful emissions from energy production. The methodology basis on the open statistics data and analysis of the energy balance of new energy production technologies are considered. The motivation for the using renewable energy sources in industrialized and developing countries is investigated. A review of new technologies for the using biomass as a fuel is made, which allows for efficient processing of biomass, including gasification, co-production of heat and electricity, fuel use of combustible gases generated at landfills, and production of fuel for transport in the form of methanol and biodiesel.

The aim of the executed research is to determine the influence of harvesting renewable energy on the labour market. Eurostat Databases provided a source of empirical data concerning the amount of produced energy. The number of the employed and the performance of the installed equipment were determined thanks to reports drafted by EurObserv’ER or International Renewable Energy Agency (2016). The following sectors were considered: solid biofuels, biogas, liquid biofuels, geothermal, hydropower, municipal waste, solar photovoltaic, solar thermal and wind power. The research concerned 28 member states of the EU between 2009 and 2015. The results presented were based on averaged data on both employment and the volume of primary energy production and installed capacity. The estimated models show that the solar and wind energy sectors were characterized by the highest labor intensity in the analyzed period.

Nowadays, in the context of climate change, efficient energy management and increasing the share of renewable energy sources in the energy mix are helping to reduce greenhouse gases. In this research, we present the energy system and its management and the possibilities of its development through the example of an ecovillage. The basic goal of such a community is to be economically, socially, and ecologically sustainable, so the study of energy system of an ecovillage is especially justified. As the goal of this community is sustainability, potential technological and efficiency barriers to the use of renewable energy sources will also become visible. Our sample area is Visnyeszéplak ecovillage, where we examined the energy production and consumption habits and possibilities of the community with the help of interviews, literature, and map databases. By examining the spatial structure of the settlement, we examined the spatial structure of energy management. We formulated development proposals that can make the community’s energy management system more efficient.
