Maintaining grid stability is a challenge as utilities rush to add renewable power to their generating portfolio. The business case for renewables is undeniable: as prices for wind turbines and solar panels keep dropping and the costs of installation go down, renewable electricity becomes some of the cheapest power available. But the inherently inconsistent nature of solar and wind energy has grid operators looking for new ways to seamlessly integrate their output into the system. This challenge is being faced around the world, and in the U.S. it is playing out initially in California.This article takes a closer look at the steps California is taking to smooth out the duck curve, a graph of power production over the course of a day that shows the timing imbalance between peak demand and renewable energy production.

Photovoltaic (PV) energy is one of the most promising renewable energies in the world due to its ubiquity and sustainability. However, installation of solar panels on the ground can cause some problems, especially in countries where there is not enough space for installation. As an alternative, floating PV, with advantages in terms of efficiency and environment, has attracted attention, particularly with regard to installing large-scale floating PV for dam lakes and reservoirs in Korea. In this study, the potentiality of floating PV is evaluated, and the power production is estimated for 3401 reservoirs. To select a suitable reservoir for floating PV installation, we constructed and analyzed the water depth database using OpenAPI. We also used the typical meteorological year (TMY) data and topographical information to predict the irradiance distribution. As a result, the annual power production by all possible reservoirs was estimated to be 2932 GWh, and the annual GHG reduction amount was approximately 1,294,450 tons. In particular, Jeollanam-do has many reservoirs and was evaluated as suitable for floating PV installation because of its high solar irradiance. The results can be used to estimate priorities and potentiality as a preliminary analysis for floating PV installation.

Energy policies established in 2005 have made Portugal one of the top renewable power producers in Europe, in relative terms. Indeed, the country energy dependence decreased since 2005, although remaining above EU-19 and EU-28 countries in 2015 (77.4% vs. 62.4% vs. 54.0%, respectively). Data collected from governmental, statistical, and companies’ reports and research articles shows that renewables and natural gas assumed a growing importance in the Portuguese energy mix along time, while oil followed an opposite trend. Recently, the country remarkably achieved a full 70-h period in which the mainland power consumed relied exclusively on renewable electricity and has several moments where power production exceeds demand. Currently, the main option for storing those surpluses relies on pumped hydro storage plants or exportation, while other storage alternatives, like Power-to-Gas (PtG), are not under deep debate, eventually due to a lack of information and awareness. Hence, this work aims to provide an overview of the Portuguese energy sector in the 2005–2015 decade, highlighting the country’s effort towards renewable energy deployment that, together with geographic advantages, upholds PtG as a promising alternative for storing the country’s renewable electricity surpluses.

The paper is related to the solar energy power generation, more specifically the paper revolves around the topic of solar tree. This paper shows how efficient and important is the solar tree for this generation. This presents how solar trees converts the solar energy into electrical energy. Sunlight irradiates daily and blasts out an enormous amount of solar energy towards the earth, the total energy that is received from the sun is more than enough for humanity to run for many years, still the received solar energy is not harnessed properly and hence there is not sufficient energy production in the world. Since solar panels are the efficient method nowadays for generating electrical energy from the solar energy, but solar panels requires lot of space to install. Hence this paper solve this problem by using solar tree that is mounting of solar panels on artificial tree..

The study deals with the socio-economic geographical analysis of the solar energy production — one of the most rapidly developing industries of the world energy complex. The aim of the study is to identify and explain main features of the territorial structure of solar energy production and assess its role and place in the world. The paper also investigates the factors that affect the development of solar energy production itself as well as the deployment of individual solar panels or solar power stations. The study carried out is based on the review of datasets and official documents which enable to draw a conclusion that the result of an intensive development of solar energy production is its dynamic spatial expansion visible in the emergence of new poles of growth which largely changes the territorial structure of the industry, transforming it from a monocentric to polycentric.

Renewable Energy Production

<p>Renewable energies, like solar and wind energy, play an important role in current and future energy supply in Germany and Europe. The renewable energy production highly depends on weather, which leads to an increasing impact of the meteorological fluctuations on energy production.</p><p>Here, climatological datasets with high spatial and temporal resolution are used to simulate the electrical energy production from photovoltaic (PV) installations and wind turbines. For the solar radiation the CM SAF SARAH 2.1 dataset is used, which includes global and direct radiation with a temporal resolution of 30 minutes and a grid spacing of 0.05°. The data is available from 1983 to 2017. The regional reanalysis COSMO-REA6 provides hourly wind speed data from 1995 to 2015 with a spatial resolution of 6km. Based on these datasets capacity factors are calculated for PV and wind energy for Germany. Using the spatial distribution of solar panels and wind turbines as well as electrical power generation data from 2015 the simulated capacity factors were converted into (potential) hourly power generation in Germany from 1995 to 2015. </p><p>The main aim of this study is to identify weather regimes where renewable energy production from solar and wind was comparable low. Due to high power production from solar radiation, which exhibits a comparable low variability and high predictability, in summer, all low production events occur in winter. During winter, wind power is the main contributor to renewable energy production. On the basis of the hourly time series of simulated power production the weather regimes that are associated with multiple days of low renewable energy production are identified and analysed. European regions are identified that exhibit comparably high potential renewable power production for those weather regimes with low energy production in Germany.  </p>

Modern theoretical views point to the increasing role of renewable energy sources, biofuels in particular, as a way of creating a sustainable economy and an important condition for successful socio-economic development. Various methods of regulation are used to stimulate the production of biofuels in the world. The heterogeneous socio-economic situation of the world's countries makes it necessary to solve a whole range of scientific tasks to continuously optimize existing national programs for the development of the energy sector and determine the place of renewable energy production in them. The global heterogeneous socio-economic situation makes it necessary to solve a whole range of scientific tasks to continuously optimize existing national programs for energy sector development and determine the place of renewable energy production. The purpose of this study was to study the regulatory framework features for biofuel production in Russia according to the available target indicators for the development of the renewables and taking into account the experience of some leading countries. Based on the analysis, a number of directions for the development of regulatory support for biofuel production in Russia are identified: organizational, resource, environmental, scientific, educational, and economic. The collected information on the accumulated experience of the Russian Federation in the field of production of renewables is presented, as well as relevant materials available in some developed and developing countries. Based on these data, it is noted that the regulation of biofuel production by processing solid industrial, agricultural and household wastes containing organic compounds (biomass) can be considered as one of the promising approaches to protecting the environment from anthropogenic pollution both in the Russian Federation and in other countries. Thus, this approach in the future may be of key importance for the preservation and improvement of existing environmental conditions.
