1. Renewable energy comes from natural sources that are replenished, including sunlight, wind, rain, tides, waves, and geothermal heat.
2. Solar energy has the highest available energy flux of all renewable sources. Common instruments for measuring solar radiation include pyranometers, pyrheliometers, sunshine recorders, and albedometers.
3. Wind power currently makes the largest contribution to renewable power production, followed by solar and geothermal. Tidal range is greatest during spring tides when the sun and moon are aligned.

Conclusion
Renewable energy is making its move. Eighteen percent of all electricity in the United States was produced by renewable sources in 2017, including solar, wind and hydroelectric dams. That’s up from 15 percent in 2016.
According to data released by the International Renewable Energy Agency (IRENA), by the end of 2017, global renewable generation capacity increased by 167 GW (gigawatts) and reached 2,179 GW worldwide. This represents a yearly growth of around 8.3 percent, the average for seven straight years in a row.

Studying the factors affecting solar power generation systems performance ( S...IJERA Editor
Solar energy is a huge, clean and renewable source of energy. It is also available everywhere on the earth. However, there are many technical and economic difficulties need to be solved so that solar energy becomes a strong competition against the traditional energy sources. Energy from the sun can be used successfully in electric power generation systems. Depending on the climate conditions and the use of a properly designed, installing and maintained system can meet a large demand in this request. Work plane for this research will include many steps, the first step will include an introduction to solar energy. The second step will be a short review of the solar energy availability, geometry, fields of applications and the largest commercial application of solar energy is the solar thermal power generation. In addition, the most common types of solar thermal power plants, the solar field, heat transfer fluid and the power conversion system types will be explained in detail. The third step, a simple analysis for the solar thermal power plant will be explained in order to predict the optimum conditions leading to maximum performance. Discussions of results will be the fourth step. The last step a conclusion and recommendation for future work will also be included.

Solar Radiation and the Seasons
The amount of solar energy (radiation) striking the
outer edge of the atmosphere is not uniform over the
face of Earth at anyone time, nor is it constant
throughout the year at any particular place. Rather,
solar radiation at any location and time is determined
by the Sun'.

Aiims previous year sample paper set 2Prabha Gupta
Find here previous year AIIMS question papers and solved sample question bank with answer keys at Aglasem. Visit @ https://admission.aglasem.com/aiims-mbbs-2019/
This paper is a mathematical study for finding the amount of solar radiation on the surface of the
Photovoltaic (PV) system affected due to the variation in the slope (tilt angle) of the PV system along with the
background theory of the attenuation of the solar radiation. The power density is maximum when the solar moduleabsorbing
surface is perpendicular to the sun and in all other cases module power is always lesser than the incident
power. Hence extra addition of panels with fixed tilt is no longer economical viable when electricity demand
increases. Theoretical estimation of solar radiation on the slope of the PV surface from the radiation available on
the horizontal surface is evaluated and the results are presented on the basis of the data available and proposed
mathematical model for the calculation of the total amount of solar radiation on tilted surface.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
