What were the results of World War II, both nationally and internationally?
What were the reasons for the decline and fall of the Soviet Union?
Solar energy is one of the most widely used and best-developed renewable energies. When sunlight is absorbed by solar panels, the solar energy knocks electrons off from the atoms, allowing the electrons to flow through the material and produce electricity. This process of converting light (photons) to electricity (voltage) is called the photovoltaic (PV) effect. (http://www.chemistryexplained.com/Ru-Sp/Solar-Cells.html) Solar energy is effectively infinite. The Sun’s energy is so abundant that more energy is transferred to our planet in an hour’s sunlight than the entire global electricity consumption for a year (https://books.wwnorton.com/books/The-Great-Transition/). It is also one of the fastest expanding renewable energy sources. With quicker technical gains and stronger policy support, the price of solar power is dropping rapidly. Figure. Annual photovoltaic addition history versus International Energy Agency (IEA) World Energy Outlook (WEO) predictions from 2002 to 2016. The graph shows exponential growth in solar energy capacity and a continuous underestimation by WEO. https://2oqz471sa19h3vbwa53m33yj-wpengine.netdna-ssl.com/wp-content/uploads/2017/05/iea-predictions-solar.jpg Figure. In the Evolving Transition scenario (ET scenario), which is premised on a demand for fossil fuels that vastly exceeds the carbon budget for limiting temperature rises to 1.5-2C, solar cost continues following its learning curve. The module cost falls by around 24% with every doubling of cumulative capacity. The rate of decline slows down in the BP 2018 Outlook, as it takes longer to double the cumulative capacity later on the learning curve. However, there are still unsolved issues in using solar power. We are currently only capable of harvesting a small part of the light spectrum. We harvest the visual light spectrum while the IR and UV su>GET ANSWER
