In the former Soviet Union, electric traction eventually became somewhat more energy-efficient than diesel. Partly due to inefficient generation of electricity in the USSR (only 20.8% thermal efficiency in 1950 vs. 36.2% in 1975), in 1950 diesel traction was about twice as energy efficient as electric traction (in terms of net tonne-km of freight per kg of fuel). But as efficiency of electricity generation (and thus of electric traction) improved, by about 1965 electric railways became more efficient than diesel. After the mid 1970s electrics used about 25% less fuel per ton-km. However diesels were mainly used on single track lines with a fair amount of traffic so that the lower fuel consumption of electrics may be in part due to better operating conditions on electrified lines (such as double tracking) rather than inherent energy efficiency. Nevertheless, the cost of diesel fuel was about 1.5 times more (per unit of heat energy content) than that of the fuel used in electric power plants (that generated electricity), thus making electric railways even more energy-cost effective.
What year could be marked as year when electric railways more efficient than diesel ones?
1965

Spring and autumn have, on average, mild days and fresh nights but are changing and unstable. Surprisingly warm or cool weather occurs frequently in both seasons. In winter, sunshine is scarce; days are cold but generally above freezing with temperatures around 7 C (45 F). Light night frosts are however quite common, but the temperature will dip below 5 C (23 F) for only a few days a year. Snow falls every year, but rarely stays on the ground. The city sometimes sees light snow or flurries with or without accumulation.
Does Paris see snow?
sometimes sees light snow or flurries

Franklin S. Harris was appointed the university's president in 1921. He was the first BYU president to have a doctoral degree. Harris made several important changes to the school, reorganizing it into a true university, whereas before, its organization had remnants of the Academy days. At the beginning of his tenure, the school was not officially recognized as a university by any accreditation organization. By the end of his term, the school was accredited under all major accrediting organizations at the time. He was eventually replaced by Howard S. McDonald, who received his doctorate from the University of California. When he first received the position, the Second World War had just ended, and thousands of students were flooding into BYU. By the end of his stay, the school had grown nearly five times to an enrollment of 5,440 students. The university did not have the facilities to handle such a large influx, so he bought part of an Air Force Base in Ogden, Utah and rebuilt it to house some of the students. The next president, Ernest L. Wilkinson, also oversaw a period of intense growth, as the school adopted an accelerated building program. Wilkinson was responsible for the building of over eighty structures on the campus, many of which still stand. During his tenure, the student body increased six times, making BYU the largest private school at the time. The quality of the students also increased, leading to higher educational standards at the school. Finally, Wilkinson reorganized the LDS Church units on campus, with ten stakes and over 100 wards being added during his administration.
How many new LDS Church wards were added during Wilkinson's presidency?
