Soleimani's killing sharply escalated tensions between the U.S. and Iran and stoked fears of a military conflict. Iranian leaders vowed revenge, while U.S. officials said they would preemptively attack any Iran-backed paramilitary groups in Iraq that they perceived as a threat. Many in the international community reacted with concern and issued statements or declarations urging restraint and diplomacy. Five days after the airstrike, Iran launched a series of missile attacks on U.S. forces based in Iraq, the first direct engagement between Iran and the U.S. since the naval battle precipitating the Vincennes incident on 3 July 1988. Following the shootdown of Ukraine International Airlines Flight 752 amidst the escalation, leaders from both countries seemed reluctant to further escalate the crisis.
Module performance is generally rated under standard test conditions (STC): irradiance of 1,000 W/m2, solar spectrum of AM 1.5 and module temperature at 25°C. The actual voltage and current output of the module changes as lighting, temperature and load conditions change, so there is never one specific voltage, current, or wattage at which the module operates. Performance varies depending on the time of day, amount of solar insolation, direction and tilt of modules, cloud cover, shading, state of charge, temperature, geographic location, and day of the year. The fluctuations in voltage and current can be logged with a multimeter or data logger.
More InfoThe strike occurred during the 2019–20 Persian Gulf crisis, which began after the U.S. withdrew from the 2015 nuclear deal with Iran in 2018, reimposed sanctions, and accused Iranian elements of fomenting a campaign to harass U.S. forces in the region. On 27 December 2019, the K-1 Air Base in Iraq, which hosts Iraqi and U.S. personnel, was attacked, killing an American contractor. The U.S. responded by launching airstrikes across Iraq and Syria, killing 25 Kata'ib Hezbollah militiamen. Days later, Shia militiamen and their supporters retaliated by attacking the U.S. embassy in the Green Zone.

More InfoA notable feature of Indian food is the existence of a number of distinctive vegetarian cuisines, each a feature of the geographical and cultural histories of its adherents. The appearance of ahimsa, or the avoidance of violence toward all forms of life in many religious orders early in Indian history, especially Upanishadic Hinduism, Buddhism and Jainism, is thought to have been a notable factor in the prevalence of vegetarianism among a segment of India's Hindu population, especially in southern India, Gujarat, and the Hindi-speaking belt of north-central India, as well as among Jains. Among these groups, strong discomfort is felt at thoughts of eating meat, and contributes to the low proportional consumption of meat to overall diet in India. Unlike China, which has increased its per capita meat consumption substantially in its years of increased economic growth, in India the strong dietary traditions have contributed to dairy, rather than meat, becoming the preferred form of animal protein consumption accompanying higher economic growth.
More InfoAverage pricing information divides in three pricing categories: those buying small quantities (modules of all sizes in the kilowatt range annually), mid-range buyers (typically up to 10 MWp annually), and large quantity buyers (self-explanatory—and with access to the lowest prices). Over the long term there is clearly a systematic reduction in the price of cells and modules. For example, in 2012 it was estimated that the quantity cost per watt was about US$0.60, which was 250 times lower than the cost in 1970 of US$150. A 2015 study shows price/kWh dropping by 10% per year since 1980, and predicts that solar could contribute 20% of total electricity consumption by 2030, whereas the International Energy Agency predicts 16% by 2050.
