Southern Europe's most emblematic climate is that of the Mediterranean climate, which has become a typically known characteristic of the area. The Mediterranean climate covers much of Portugal, Spain, Southeast France, Italy, Croatia, Albania, Montenegro, Greece, the Western and Southern coastal regions of Turkey as well as the Mediterranean islands. Those areas of Mediterranean climate present similar vegetations and landscapes throughout, including dry hills, small plains, pine forests and olive trees.
What are two broad categories of similarity among countries which have a Mediterranean climate?
vegetations and landscapes

In the last two decades, photovoltaics (PV), also known as solar PV, has evolved from a pure niche market of small scale applications towards becoming a mainstream electricity source. A solar cell is a device that converts light directly into electricity using the photoelectric effect. The first solar cell was constructed by Charles Fritts in the 1880s. In 1931 a German engineer, Dr Bruno Lange, developed a photo cell using silver selenide in place of copper oxide. Although the prototype selenium cells converted less than 1% of incident light into electricity, both Ernst Werner von Siemens and James Clerk Maxwell recognized the importance of this discovery. Following the work of Russell Ohl in the 1940s, researchers Gerald Pearson, Calvin Fuller and Daryl Chapin created the crystalline silicon solar cell in 1954. These early solar cells cost 286 USD/watt and reached efficiencies of 4.56%. By 2012 available efficiencies exceed 20% and the maximum efficiency of research photovoltaics is over 40%.

IBM's employee management practices can be traced back to its roots. In 1914, CEO Thomas J. Watson boosted company spirit by creating employee sports teams, hosting family outings, and furnishing a company band. IBM sports teams still continue in the present day; the IBM Big Blue continue to exist as semi-professional company rugby and American football teams. In 1924 the Quarter Century Club, which recognizes employees with 25 years of service, was organized and the first issue of Business Machines, IBM's internal publication, was published. In 1925, the first meeting of the Hundred Percent Club, composed of IBM salesmen who meet their quotas, convened in Atlantic City, New Jersey.
In 1925 the first meeting of this group occurred.
