Standalone renewable energy is widely used to power irrigation systems. However, in agricultural facilities, electricity from the grid and diesel are also consumed. The design and sizing of renewable generation involves difficulties derived from the different seasonal profiles of production and demand. If the generation is 100% renewable, a considerable energy surplus is usually included. This paper is focused on a renewable energy system, which has been installed in a vineyard, located in the northeast of Spain. With energy from the photovoltaic fields, the wastewater treatment plant of the winery, a drip irrigation system and other ancillary consumptions are fed. The favourable effect of combining consumptions with different seasonal profiles is shown. The existence of some deferrable loads and the energy management strategy result in an aggregate consumption curve that is well suited to production. Besides, the required energy storage is relatively small. The surplus energy is used for the on-site production of hydrogen by the electrolysis of water. The hydrogen refuels a hybrid fuel cell electric vehicle, used for the mobility of workers in the vineyard. In summary, electricity and hydrogen are produced on-site (to meet the energy needs) from 100% renewable sources and without operating emissions.

Energy sovereignty in Indonesia is experiencing problems with a decline in national energy security. Indonesia's energy system is currently facing serious challenges. The imbalance in the condition of energy supplies with national energy needs, especially the oil and gas sector and efforts to fulfill national energy needs in a sustainable manner are the main problems of this nation in the energy sector. It is absolutely necessary to have strategic efforts in the field of creating new and renewable energy. Although the government has issued various policies to catch up, but to realize national energy security, it is necessary to urgently regulate the development of renewable energy as a form of supporting national energy security. As for the formulation of the problems raised in this study are: support national energy security in Indonesia? 2) what is the urgency of regulating the development of renewable energy as a form of supporting national energy security? This research will use normative juridical research and supported by empirical juridical research so that it will be able to see the conditions of developing renewable energy as a form of supporting national energy security in Indonesia. To realize this, it is necessary to urgently regulate the development of renewable energy as a form of supporting national energy security.

Where renewable energy sources, solar, hydro, wind are available the remote communities and businesses can be provided with the most reliable and affordable source of electrical energy. This paper presents a model of safari rest contains all the necessary services for the interested tourists who visit the safari Sinai desert. The PV energy system provides the rural energy needs of remote communities. A photovoltaic renewable energy system is designed to feed the global Ac and Dc electrical required load of this safari rest. The benefits of photovoltaic renewable energy at rural applications are its versatility and convenience. This model of safari rest must be taken in consideration by Egyptian Government as it will provide the tourism plane by new interested tourism field which put a big spot on Red sea area: El Ghordaka.

India’s energy needs are in demand with the increase in energy and other electric uses which is highest among the world. There are sectors which heavily rely on energy generated by fossil fuels but there is also seen a paradigm shift towards renewable energy sources. If India continues to rely on the former then they end up blocking development in energy system meeting uncertainties and face difficulties in supply of fossil fuels. To meet the fast-growing economy, India needs to supply the energy 3-4 times more of what they are supplying now. Government of India has become aware of the situation and has started facilitating polices in action towards a sustainable energy. As of 2019, India’s on grid renewable energy capacity is 85.9 GW. Government is working to establish 500 GW of renewable energy source by 2030.

Hybrid Renewable Energy

The demand for electricity is increasing day by day and canNot be satisfactorily met without Non-renewable energy sources. Renewable energy sources such as wind and sun are universal and environmentally friendly. These renewable energy sources are the best options for meeting global energy needs, but they are unpredictable due to natural conditions. Using solar and wind hybrid renewable energy systems is the best option to take advantage of these available resources. This article introduces wind energy conversion systems, solar energy conversion systems, and multistage inverters.

Splitting Water

The growth of industrialization, which is forced to use non-renewable energy sources, leads to an increase in environmental pollution. Therefore, it is necessary not only to reduce the use of fossil fuels to meet energy needs but also to replace it with cleaner fuels. Production of hydrogen by splitting water is considered one of the most promising ways to use solar energy. TiO2 is an amphoteric oxide that occurs naturally in several modifications. This review summarizes recent advances of doped TiO2-based photocatalysts used in hydrogen production and the degradation of organic pollutants in water. An intense scientific and practical interest in these processes is aroused by the fact that they aim to solve global problems of energy conservation and ecology.

System Focus

The integration of previously unconnected sectors of the energy system is considered one of the most important strategies for reducing CO2 emissions. Many studies on technological innovations that deal with the transition to a sustainable energy system focus on innovation niches as a favorable environment within which new solutions can be tested and made ready for the market. This paper examines how protection in such a niche, in combination with organizational path dependency, supports the integration of renewable energy in residential buildings. The results presented are based on a case study on the integration of the electricity, heat, and gas sectors in a housing pilot project, in which local energy needs are met and electricity is fed into the grid in a flexible way. Our findings indicate that favorable conditions for inter-sectoral innovation can be achieved through niche protection, complemented by path dependency in organizational routines and culture.

Business As Usual

Controversy exists as to whether renewable energy (RE) can provide for all the world’s energy needs. The purpose of this paper is to help resolve this vital question. Official forecasts see a resumption of a business-as-usual world after the pandemic-induced recession, with further economic growth out to at least 2050. The novel approach taken in this paper is to assume that such a world is fueled entirely with RE at global energy levels at or above those of today, and then to examine whether this scenario is feasible. Because the intermittent primary electricity sources, wind, and solar power, would have to supply nearly all this energy, a simplification made for this analysis is that they do supply 100% of all energy, including non-electrical energy needs. It is found that the energy that could be delivered by these two sources is much less than often assumed, for several reasons: The declining quality of inputs; the need for inclusion of uncounted environmental costs; the need for energy conversion and storage; and the removal of existing fossil fuel energy subsidies. It is concluded that a future world entirely fuelled by RE would necessarily be a lower-energy one.
