This research aims to study the acceptance of real management of designing electrical generation plants that work using solar energy and wind energy, to explain the benefits for the decision makers of the use of the solar energy and wind energy, and to define the most important obstacles that hinder the use of solar energy in generating electricity in spite of fulfilling the environmental conditions as clean energy and renewing energy contribute to sustainability of natural resources. The descriptive methodology was used by going back to reference material including books, and scientific journals and periodicals as well as scientific researches to identify the real management and design of electrical plant generation using solar energy and wind energy. A questionnaire was distributed among the study sample that was composed of the engineers working in energy field and electrical generation plants, the general institute for environment, Kuwait Institute for Scientific Research, and Kuwait Society of Engineers. 203 responses were received from the study sample. Results of the study showed the presence of obstacles and special problems related to the use of solar energy that face the decision makers with regard to the ability for acquiring important advanced technology and the huge financial support and the partnership of the private sector and training of unskilled human resources. And it was declared that there is a huge focus and attention in generation electrical energy from fossil fuel because of its presence and sustainability in investment in this field and the ability to fulfill the needs of the local market from energy.

Efficiency And Productivity

This paper examines the dual efficiency of bioenergy, renewable hydro energy, solar energy, wind energy, and geothermal energy for selected OECD countries through an integrated model with energy, economic, environmental, and social dimensions. Two questions are explored: Which renewable energy alternative is more dual efficient and productive? Which renewable energy alternative is best for a particular country? Data envelopment analysis (DEA) is used for the efficiency evaluation, and the global Malmquist productivity index is applied for productivity analysis. Results indicate bioenergy as the most efficient renewable energy alternative with a 20% increase in average efficiency in 2016 compared to 2012. Renewable hydro energy, wind energy, and solar energy show a 17.5%, 16%, and 11% increase, respectively. The average efficiency growth across all renewable energy alternatives signifies major advancement. Country performance in renewable energy is non-monolithic; therefore, they should customize their renewable energy portfolio accordingly to their strengths to enhance renewable energy efficiency. Renewable hydro appears to have the most positive productivity change in 2016 compared to 2012, while solar energy regressed in productivity due to its scale inefficiency. All renewable energy alternatives have relatively equal average pure efficiency change. The positive trend in efficiency and productivity provides an incentive for policy makers to pursue further development of renewable energy technologies with a focus on improving scale efficiency.

In the high altitude, solar energy, biomass energy and wind energy are widely available and renewable energy sources. It will improve the region's living levels at high altitude and the ecological environment when developed efficiently and in low cost. Making full use of renewable natural resources is of great value and significance to sustain the development of high-altitude areas of the economy. This paper is a kind of research and study, which based on new energy and aims at making full use of solar energy, wind energy, biomass energy complementary relationship and physical changes between planting and breeding to improve the renewable energy industry, integrated, modular for the high altitude area residents gathered .

Climatic Information

<p>The variability of renewable power generation is often quantified based on modern reanalyses such as ERA5 or MERRA-2 which provide climatic information over the last few decades. Compared to infrastructure lifetimes, modern reanalyses cover only short periods and may consequently fail to sample relevant longer-term climate variability. While there is evidence for multi-decadal variability in wind power generation [Wohland et al. (2019), Zeng et al. (2019)], hydropower [Bonnet et al. (2017)] and solar energy [Sweerts et al. (2019)], a consistent treatment of multi-decadal variability has not been achieved. </p><p>This knowledge barrier can potentially be overcome using 20th century reanalyses which provide internally consistent fields of energy-relevant variables (e.g., solar radiation, precipitation, temperature and wind). However, the provision of reliable climatic information on these timescales is known to be a challenge due to, for example, the evolution of measurement techniques. Some cases of spurious trends and other shortcomings of the datasets are known. It is therefore of utmost importance to quantify uncertainties prior to usage in energy system studies. To this end, we systematically compare 20CRv3, 20CRv2c, CERA20C and ERA20C with respect to variables needed in renewable energy assessments and report similarities and discrepancies accross the datasets. The focus is given to substantial differences with respect to multi-decadal solar radiation variability in Europe, also known as dimming and brightening. </p><p><br>References</p><p>Bonnet, R., Boé, J., Dayon, G. & Martin, E.
